Hi all - I'll have my TCS-8 station (AM), Swan 350 (AM/SSB), and RT-68/GRC (6m WBFM) up and running at various times. I'll be monitoring w/my Hammarlund SP-210 SX and BC-312 also.

Note my Northern CA QTH, so a QSO w/the TCS will be a remarkable thing, hihi! Sunspots may be w/us next weekend, though.

Cheers and good DX!

Cheers!

There's the answer.  I have a Heath SB200 behind mine on AM fone.  Net 
result is a strapping signal that'll match any Viking I(or II) / DX100 /
etc.... or a BC-669/PE-110 'in full.'

Message-ID: <000d01c865c1$abe934e0$6401a8c0@boudreaux>

I built another of my little converters to go in a second LF receiver
(corrected diagram):
http://home.netcom.com/~arc5/converter.JPG

I grabbed what I thought was another color burst xtal from the parts
bins at the goodies store.
I also deleted the 20-100 pFd trimmer 
and used a fixed 47 pFd cap, 
tuning the input with the slug in the coil.

It tuned up and worked fine, but 3880 KC 
was showing up at 339 KC, not 302.
There was also a large SWBC image just down from the 
"AM Ghetto."  I looked at the xtal and it's actually 
marked 17915 KC!  Try as I might, I can't seem to find 
any formula that gets 339 KC out
 with 17915 LO and 3880 input.  

For some reason, this one is more sensitive than the one
that used the color burst xtal, and a simple wave trap got 
rid of the image.  Anyone have a clue??

Also:  This set's T/R switches by killing the receiver B+,
and I didn't want to drill any holes to bring a PTT line or 
put in a clunky relay, etc.  So I built a voltage divider that
cuts the 250 VDC*  down to about 5.5 volts.  
I put 50-Kohms 2 watts in series with 2200 ohms 1 watt
and put a 6-volt, 1 watt zener across the 2200 ohm resistor to 
protect the converter, should a surge or resistor change bring
the voltage too high.  +5 to +6 volts available at the junction
and it works great.

Hi

My bet is that it's a 5th overtone crystal. That would give you 297 Kc  
out. Since the ratio of fundamental to 5th is never exact, the crystal  
may well be correct on the fundamental to give you 339.

Anyone need any RT-18/ARC-1 parts? I have
a parts unit that has already given up a couple
of small pieces for another unit.

Kind of a shame, it looks like the previous owner
started an AC power supply conversion by ripping out
the rear panel connector, along with a good portion of
the wiring to the connector, and some of the harness
in the autotune control area. Then he stopped.

Rest of it mostly untouched. Let me know if you need anything.

Subject: [Milsurplus] CX CW Contest Report
Message-ID: <006d01c8667f$c13c66a0$7536c847@HAL1000>

    This years CX CW  event was great and the activity really did  pick up 
in the late afternoon and evening. Much better than last year. Many thanks 
to WQ8U, N5AIT,W8KGI and AA4RW for keeping the event going all these years. 
A great event  and I quote from the CX web site:



    The CX is a great no pressure contest. ?The object is to encourage 
restoration, operation and enjoyment of this older "Classic" equipment?

    I especially enjoy putting some of the military equipment on the air.

My goal this year was to get sets on the air and not try to make large 
numbers of contacts. My CW skills are rusty ask K2TOP he will tell you.



The Phone portion of the CX contest is Next Sunday February 10th!



    Since the CX allows me to use a  lot of the military radio projects I 
have been working on during the year I have posted some

brag photos of equipment and the link is below.



Early in the event I worked a couple of AWA stations as they were having 
their contest at the same time.I started off on 40 CW with my Wireless Set 
No. 19  and milked  several  contacts   with non CX stations and a few AWA 
stations.  I later received an email from KZ8G one of the NON CX stations 
who worked me on the Wireless Set and  stated: Thanks for the great QSO! 
?It was fun  tuning your "yooping" CW signal up  and down using the RIT on 
my TS  830S!? Well I guess the WS No.19 does indeed yoop just a little tiny 
bit. I then  fired up the GRC-109 with my latest vfo project a compact 
external solid state VFO. The little VFO ran off of internal  batteries and 
it had been through several meets this last year  and  the voltage was 
getting a little on the low side ,so as I keyed the transmitter but had to 
tune the VFO to keep it on frequency.  Those dag gone dollar store batteries 
only lasted 6 or 7  months.   My internal antenna relay modification on the 
GRC-109 worked great.

Then I switched over and plugged in the HV supply on the Navy GO-9 and 
immediately blew a fuse. I wondered what the loud hum was and then the fuse 
let go with a nice  snap sound.  I did not know that those 4 prong plugs 
( the ones with two big pins and the two small pins) would fit into 4 pin 
socket  upside down. The diodes (K2AW?s) on the HV supply  did survive, they 
are great  diode packs.  After the HV crisis  I got on  with the Navy GO-9 
and RBJ setup and qualified it on 40 , this was the first time I had tested 
the new power supplies and had the HV for the 803 final set to ?medium? on 
the  Variac. Prior to the CW CX contest I had covered up the power supplies 
with a red milk crate as the power supplies   were  still in the testing 
phase and not mounted in the G0-9 rectifier cabinet.  I stole the idea of 
the milk crate from somewhere but can?t remember who it was.   Following 
K2WI?s and KA3EKH?s advice I was keying the screen voltages with a relay, it 
interesting listening to the relay   clicking and klacking while I was using 
a special home brew key which also was making a nice clanking sound.  The 
evening  before the contest  I was testing the  GO-9 and noticed that the 40 
meter second harmonic on  20 meter was only about 20 db down so I am sure 
someone heard me on 20 while I was on 40 but there is no CX rule that say 
you can not transmit on two bands at once. Oh well probably get some sort of 
FCC violation but what can they do, they can?t send me back overseas. 
FCC Violation number 1?

 I then gang banged NS3E on 40 CW and changed equipment several times for 
some easy contacts.

Question: Why is it that on 40 meters everyone has to stay around 7040 when 
we have the whole band? And no one will dare tune up 10-15 Kcs  above 7040.

        Then I  went over to the  ?Flight Deck? (note 1) , the Collins 
18S-4 dynamotor was having start up  problems getting up to speed,  I 
quickly checked  my power supply combination of a   parallel  50 amp Lambda 
and a 20 Amp Solo, both lights were ?on? but the dyno was slow, oh so slow, 
so managed to get the dyno up to speed by clicking several times but only 
made a single contact. It would take about 5 seconds to click the dyno up to 
speed. Later found that one of the ?On? lights was the ?blown fuse? light on 
the Solo. duhh I then fired up the 32RS-1 that I modified for CW and worked 
with it for a while. (Note 1: the term ?Flight Deck? and the  use aircraft 
style equipment bays to house and display WWII  aircraft radios was coined 
by Mike Hanz at AAFRADIO.org.)

Early in the evening I  turned on my Fitzgeralds Junk Yard KWM-2A (salvaged 
from an Aluminum scrap pile from Dover AFB) and listened and listened and 
listened  on 80 meters  but did not hear anything, so thought it was 
strange. So sent out several CX CQ?s, still nothing. Then while tuning 
around  what I thought was ?3585? I heard  New York VOLMET transmitting 
weather so then realized that  I was out of band and was one crystal 
position low. The new York frequency is 3485. duhh   Probably get another 
FCC violation.                              FCC Violation Number 2?

Finally got the right band switch selection on the 2A got on 80 CW and heard 
lots of stations  and worked W8TM with several of my stations including the 
PRC-47 and the Viking Ranger and the 32RS-1.

Then 80 meters got fairly busy with CX activity and it was easy finding  the 
K2TOP multi-operator station as I could hear it on every receiver in the 
shack, most of them were not connected to an antenna and just had the lead 
ins connected running to the CX equipment switches. Didn't try a crystal set 
but sure I would have heard them.

I then turned on the ART-13 and hooked up the new APN-4/ART AC supply, 
thought I would run it instead of the dynamotor as I was having 28 volt 
power supply problems.

My  ART-13 lost position 3 on the VFO so had to improvise and use Position 
4(3.6Mc) and crank it all the way down to the stops past 3.600 to about 
3.582 Kcs and thus managed to get it slightly below it design bottom 
frequency of  3.600. So then I had to go down to 3550 with the junk yard 
KWM-2A  and grab K2TOP and  drag him up to 3.580 so I could use  the 
ART-13/BC-348 combo. He remarked that he thought it was a little strange but 
followed me up anyway.

Question why do we all have to hang around 3550 when we have the whole band 
its just like that 40 meter thing.

          Later worked K2TOP again with the Russian R-104M using the N3FRQ 
"phantom voltage divider" power supply circuit  and then  switched over to 
the Navy GO-9 , seem eerie  as I sat using the goose neck lamp for light and 
working Rob?s TCK/RBB combination and  my using a  Navy GO-9 and RBJ, two 
Navy WWII combinations klacken away using skills and mode that just about 
completely  disappeared. Eerie.

         Then got Rob to listen for the Wireless Set on 80 and could hear 
him loud and clear over most of the band, I guess the WS-19 receiver is a 
just a little wide. But he could not hear me.  Next day I looked at the 
output of the WS-19 on 80 and it looked like a Christmas Tree so guess I had 
multiple spurs.   Oh well guess that is FCC violation 
Number 3?

Hi Gang:
Getting ready to power up the BC-348-O after a couple of years. And just 
want to check to make sure that I am doing things correct.On the power 
connector +28 volts to Pins 3 & 4, - 28 volts to Pins 7  & 8.
Do I ground pin 5 audio output also?
T 101A is set to pin 4, 4000 ohms

On the audio output is there a way to tie the rig to a speaker and still 
use the WECo headset?

That's correct for pins 3/4 and 7/8.  

Audio out is pin 1, and pin 5 is grounded internally.  You need not ground it at the plug, though it would make sense to run the low side of the external audio circuit to it.

You must jumper pin 2 to pin 6 to "unmute" (complete the HV circuits in) the receiver.  These pins are normally connected to a normally closed set of contacts on an external receive-transmit switching relay.

For the E/M/P models, component 101-A (AF output transformer) output connection for 4000 ohms is to terminal 5, and 300 ohms is to terminal 6.  I don't have an -O model, but I think it is the same as the E/M/P sets.  

Various BC-348 manuals (including the -O model) are in pdf format at:

I have the opportunity to parts out some 1950s VHF aircraft
radios, Bendix and Collins. I am pretty sure there is next to
zero interest from collectors for these, and they are HEAVY.
IF they were transceivers, that would be something in their favor;
but separates + heavy + VHF  AM + no control boxes  is voting
strongly for their demise. 

I noticed some interesting dynamotors in some of them. There
are receiver dynamotors of 220 V 80 mA, and transmit dynos
of 425 V 325 mA. These do not have the unscrew & pluck out
basing of military dynos: they mount on a chassis with 4 screws,
and then the leads from the dyno go thru a cutout in the chassis
and land on a terminal block. So not directly plugin replacement
for any mil dynamotor. Nevertheless, these voltages seem useful.
But collectors want the real thing. So i ask, are these dynamotors
worth saving? For example, the 425v one seems ready made for
the ATB transmitter. Of course, not a whole lotta ATBs out there
crying for dynamotors.

Also i noted a mod transformer for 2x 2E26 to 829B for about 40W
AM input at 415 volts. Mentioning these on the GB list seemed to 
elicit no interest; i suppose ham from-scratch builders want more
AM power than that, probably around 100W. So are these mod
xfmrs worth saving, at all?

Oh, yes: all the control boxes apparently went the way of the scrap
wire bin - as usual. -Hue Miller

I found my copy of the procurement records this evening and I have that information.

In total, the Signal Corps purchased 63,972 units.  This total breaks down as follows: 1940: 0,
1941:0, 1942: 13,585, 1943: 28,618, 1944: 21,769, 1945: 0.

Couldn't get to sleep last night, so I turned-on my little
portable shortwave receiver and tuned around.
Freq readout is pretty crude, but at around 5875 I heard 
the spanish "numbers" lady.  Just below her, at about 5870,
there was a strong station sending 5-letter code groups at
about 20 WPM in mode A-2.  Man, it was good to copy code
someplace besides the ham bands again.  
Happily copying those groups in my head, 
I finally drifted off to sleep.  No telling to whom they
were sending, but I hope they hang around for awhile.

Gang,

There appears to be a very early SP-600 (no suffix on the tag) (Serial No.
743) on the E place.

The listing is 250211892028. It might be worth a look.

A fellow contacted me because he thought this might be Navy gear. Of course,
it wasn't but sounds like it might be available at a good price. The photo
he sent shows the outside unmolested and complete with case/shock mount.

On a rare occasion of looking at the boob tube, I was watching a show about hidden underground places on the History Channel.  This particular episode was showing tunnels, forts, and the RVN headquarters underground bunkers in Vietnam.  The bunker shots under the RVN "White House" showed shots of T-368s, RTTY gear, field sets, TMC/Sp-600/R-390? receivers, and some larger transmitters.

 Remember,this equipment was abandoned when we bailed out of Vietnam.
  My Mother and Step Father gave me some nice photos of radio gear on 
display in Ho Chi Min City and it is as you describe.They were on an 
Asian Cruise that included Vietnam.Thier comment to me was that the 
people of Vietnam were the friendliest to Americans of any of the Asian 
countries they visited.
  What will we leave behind when the new administration bails out of 
Iraq?And no matter who comes out on top, the People want out so it has 
to happen.
  Thank God my cousin made it through his tour and he worked in the 
streets every day, mostly secureing and towing back to base Marine Corp 
HumVees!I've got a great shot of Cousin with his holstered .45 at a 
gunslingers rake and an arm load of Junk Food and a very disgruntled 
Marine alongside and a HumVee on the hook of the biggest tow truck 
(read VEHICLE) I have ever seen.Not the most exciting duty but he did 
not complain for lack of munchies.

Multipart question

1.  I'm using T17 with WECo F1 soldered inside then taped to body.
    Std. 50s ham trick (ok, ok - I saved the dead kellog elt.)

    Now comes a carbon mic data table

      a. have RS38 (4 tcs) that's 380 ohms.  Telephonics.  Good
         original runner

      b. T17's heart transplant F1 is 88 ohms

      c. Have Continental F1 substitute that's 220 ohms

    So do your elt.s vary all over lie these AND were elt.s soldered
    into T17 or was there once some spring doololly once to contact
    elt.?
     
2.  has anyone ever seen the dynamic mic intended for the ART-13?
    Have Moto dynamic that looks like RS38 cookie that does OK &
    looks 'period.'

3.  How deep is the ocean?

Why this?  Well to enter AWA AM sattidy nite with a TCS (cum SB200)
& ART-13.  Then starting 9A Sunday there comes CX fone hoo hah

Yup. Cementation, storage conditions, and original size of granules 
affect the resistance considerably.  The Summary Technical Report of 
Division 17, NDRC after the war records these complimentary observations 
about carbon mikes:

"Carbon-type microphones were adopted almost exclusively by the Armed 
Forces of the United States, despite the fact that all carbon 
microphones are essentially nonlinear devices.  Furthermore, their 
frequency-response characteristic depends on the level of the sound 
pressure for which the response is obtained.  They require a separate 
source of current, their performance is likely to vary with change of 
position, and they produce a certain amount of "burning noise" due to 
passage of current through the carbon granules.  In addition, there is a 
certain amount of deterioration of the carbon granules with age.  Their 
extensive use is due primarily to their very high sensitivity, far 
exceeding the sensitivity of magnetic and dynamic microphones."

>2.  has anyone ever seen the dynamic mic intended for the ART-13?
>

The intention for this capability was for British applications, so 
you'll need to get one of the WWII British aircraft mikes to be totally 
correct.  However, according to that Summary Technical Report, the 
Signal Corps MC-253-A button developed for the US mask microphone was 
"extensively tested and adopted for use by the British."   It looks like 
it's the same size as the ANB-M-C1 carbon button for the mask oxygen 
mask, so if you can find one of those buttons and stuff it in a T-17 or 
RS-38, you should be good to go.

> Must be a different configuration of coil.

Could be.  I don't have a diagram and didn't trace out the stage.
The tube was good.  The bypasses around it were bad.
Just my "best guess" as to what toasted the coil.
Luckily, the open was right at the inside of the winding,
and the coil itself had "cooked loose" from the form.
I was able to fish out a turn, glue the winding back in place 
and reconnect.  The burned insulation still works,
as the radio aligned OK.

Hi - I was in the shop last night and found that I still have 3 M-80 microphones. They are new in the packaging. This is part of a lot I had previously sold on this list about 18-months ago, everyone who purchaed them was happy with them.

$16.00 including shipping in the USA. Overseas would be $11.00 plus actual shipping cost.

Payment via Paypal is OK. Reply if interested. 

Thanks in advance.

Yes, I know they're single conversion, big and heavy, hard-to-find
power connector, etc. But I've always wanted to play with one for some
crazy reason. A few years back I nearly made a deal for a trade with
someone here or on the R-390 list, but we both got busy with life and
it fell by the wayside. Would prefer a clean, working D model but
willing to consider any.

The likelihood of finding one nearby is slim, at best.. In realty,
shipping is likely to be the more viable option. But you never know

Todd,

The B40 is an excellent receiver considering it's single conversion.  
It's sensitive, stable and the front end is bomb-proof. The dial is  
unique and a pleasure to "bandcruise" or just set and forget.
I have the D model, which I found on ebay about 4 years ago and it  
didn't cost me an arm and a leg, in fact it was very reasonable.  
Shipping from the UK cost me almost as much as the price, but even  
adding it to the purchase price the total is still not over the  
reasonable range for a 50's/60's vintage boatanchor.
Mine was practically unused, came with all the connectors and the  
original shock mount.
A friend of mine liked it after he saw mine, and I found him another  
on ebay, he got it since and takes center stage in his boatanchor  
station.

Just keep looking, they're out there...

Message-ID: <cc8.2663a7e4.34df0b8b@aol.com>

I have been trying this GRC-109. I do not think I am getting my signal  
through the coupling of the tx through to the rx ae socket. When I attach the ae  
direct to the rx there is a good signal strength but through the tx it  drops 
quite a lot. 
 
I have just changed the 18pf coupling cap, no difference. I lifted off the  2 
diodes, no difference. 
 
Anyone else noticed this problem or have any suggestions?

This is a common problem with the GRC-109. The tuned circuit on the GRC-109 
absorbs most of the signal so I used a 5  volt DC SPDT antenna relay which 
is keyed by the normal CW keying circuit and powered by the filament voltage 
picked up from   transmitter board TB2. The filament voltage was  rectified 
by a diode and capacitor. If you are not going to use the AC mains then you 
do not need to rectify the filament voltage. I used an isolation diode on 
the relay when I connected it to the keying circuit. The relay, diode, small 
cap  etc. are  easy to put in and easy to take out, no holes drilled etc. 
Also while you are inside  the transmitter check  diodes CR1 and CR2 on the 
receiver antenna port.        Pictures available.
I will try and post the information this month on my web page.

Message-ID: <004901c86b43$022b4470$db15e555@TOMAS>

Hi
I am a Swedish ham and I am using the Collins 618T-3 since many years with great progress! During tha last year, my 618T has sometimes become unstable drifting a few kHz down or up. This is really irritating! The station can be ok for half an hour and then it becomes unstable and then normal again.

I have replaced almost all modules and I have also checked the alignment of the modules A12 and A4. However, this station is kept in a barn which is not heated so the station warms up through different temperatures. But of course it should be able to handle such differencies in temperature .

So my question is if anyone of you have a solution for this problem? This is not a military station though but there are similar versions used by the airforce as well.
Best regards
Tomas Rinman

If you can't find the original stuff you might try here, John.

http://www.radiodaze.com/catalog-306-page45.pdf
or
http://www.tubesandmore.com   and look under wire and heatshrink. They 
offer parts for the vintage radio people.

I suspect as standards change or evolve that original "spec" 
wire/tubing  may now be out of spec and no longer produced.
The stuff from AES (tubesandmore) is pretty good, especially the laquer 
covered cotton wire.

Hmmm.....
I suspect these were not really total manufactures but REmanufactured,
as were the France BC-312s. That would be too much engineering and
reengingeering to no point, when there was no shortage of such equipment
already on the surplus markets.

Have we discussed WW2 Army-Airforce production numbers?
Do others have this info from "Table PR-10 Quantities of Major
Items procured by Signal Corps by Year of Delivery: 1 Jan 1940
- 31 Dec 1945" publication 1952 ?

Thanks to a friend who probably prefers to remain unnamed, i 
have this, but a photocopy of a photocopy, and in spots requires
some close looking. In some cases without further close examination
the 3 and 5 figures were so similar that a mistaken interpretation  may
have been done by me. Some interesting extracts:

Or, do a search on some of the terms in the title, like "scale SCR-508".

I have been tempted by the scale model radios i have seen offered,
including the "GI Joe" radios.
I could get rid of all my heavy metal and have my whole collection in
a shadow box hanging on the wall. Packing up a (scale model) radio
for swap or sale would be a piece of cake, 10 minute job.  No more
aching the day after moving stuff. Or dreading another  cross country
move. Looks good....???

Hi Hugh,

That's very interesting data.  86 thousand WS-19's, wow!  Can you 
extract numbers for SCR-288/BC-474, one of my favorites.

Thanks,
Al

There was NO data for SCR-288 ! I don't know why! There are
some, actually plenty, of omissions. No JT-350, no Bendix-
nomenclatured stuff, like TA-12. Why it would miss those but
include the PRC-1 i don't get.
BTW, as long as i listed SCR-183, i should have included 
SCR-283......19732

1) Some equipment should be seen more today than they are, going from what 
you would expect from the production numbers. I am thinking  of specific example
SCR-300. I "assume" this condition is from the fact that so many went overseas to
be used by allied countries, after the war.

2) Makes you really wish you could find something similar for Navy  
All we can do for Navy is maybe, guesstimate from "frequency of
sightings" and comparing to Army equipment. But that would not be any kind of
publication-ready number. The only numbers i know, or knew!, was for ARB and
ATB, which numbers leaked out by way of RCA. And the MBM and CMS, you
know the numbers had to be on the scale of the PRC-1, maybe less!

Hi Hue,

I'd like to know the ARB numbers.

Also, all the US produced WS 19s were the Mk IIs. AFAIK, no Mk IIIs were made in the
US.

Best,

I don't have these numbers at hand at present; they're "somewhere".
They came from an article by Frederick W. Chesson in AWA "Old
Timers Bulletin" from at least 20 years ago, in an article, probably,
on the ARB. As far as i can remember, the figures were roughly
17000 for ARB and 4000 for ATB. Altho the ARB & ATB seem the
"perfect match", the ARB was matched with other equipment, namely
ART-13 and ATD, thus the lesser numbers for the ATB.
What we would really like to see, is numbers for the ARA-ATA and
ARC-5.  -Hue

Just had an interesting read about US Navy communications of about 100 
years ago. The book was called:
"Manual of Wireless Telegraphy (radio) for the use of Naval 
Electricians". It was printed by the US Navy at Annapolis in 1913.
They sure used some pretty crude stuff back then.

I sure hope times have changed for the Navy because at the end of the 
book one of the appendices covers resuscitation from electric shock.

I quote two of the "rules":

   "Forcible stretching of the sphincter muscle controlling the lower 
bowel excites powerful reflex actions and stimulates a gasp 
(inspiration) frequently when other measures have failed. For this 
purpose, the subject should be turned on the side, the middle and index 
fingers inserted into the rectum and the muscle suddenly and forcibly 
drawn backward toward the spine."

    "The tongue is seized and drawn out quickly and forcibly to the 
limit then it is permitted to recede. This is to be repeated 16 times 
per minute"

I think nowadays this is probably against the Geneva Convention :)

I've got a copy of that same book here... ROBESON'S MANUAL OF WIRELESS
TELEGRAPHY.

I had a GREAT time with it at the local Society of Broadcast Engineers
meeting!  <<GRIN>>

One comment it evoked...   "If I'm so far gone that you have to resort to 
that kinda stuff, I beg of you...  just LET ME GO!!!"

Is that the book with the photos from the Alaska wireless station?
( Must have been a pretty lonely and boring duty station! )
If so- i think it was first published in 1911 and then a new edition every
year to 1914 at least. 
I sure don't remember that quoted text in it. Maybe i just had to "tune

Hi Hue,

Yes, this could be the book. This copy was printed in 1913 and is called 
the 3rd edition and there are photos of an Alaskan wireless station at 
Sitka.
The quotes are from Appendix F, rules 5 and 6.

Actually the part about the rectum is spelled out for the "summoned physician", not the operator. So you only need to hope the doc washes his hands before he comes back to his office and does a prostate check on some unsuspecting soul.....

Actually I like the part about "seizing the coattails or any piece of loose clothing" to yank the victim away as long as he is in contact with earth. Whaddya do - take out your ohmmeter and see if the guy is grounded?

This must be a fairly popular book. According to the preface it was first published in 1907. Mine is the 1913 edition.

Greetings to all the MILSURPLUS list members!

 

A quick few words from your list manager.

 

I wanted to say thanks for making the management of this list easy! Everyone
maintains a great attitude here. 

 

----------------------------------------------------------------------------
--------

 

I would ask all of you a few things to make my life a little easier.

 

Whenever mailman bounces a message, I get it. I list here a few of the more
common problems:

 

1) Non-member submissions are forbidden.

 

If you are not a member (reading the messages off the website) and respond
to the list, your message will not be sent out.  Also, in some cases, users
subscribe with one account that auto-forwards to their home account.  When
you respond, it must be from the subscribed account name. 

 

2) Users incoming quota is exceeded.

 

If your email account has a quota, please keep it purged. If  your account
continually bounces back due to the mailbox being full, the account will be
unsubscribed automatically. If  this happens, just re-subscribe once you've
cleaned up your mailbox. 

 

3) HTML or other 'fancy' text fonts & attachments

 

This list is not setup to accept any HTML or other 'fancy text' or
attachments. mailman will drop your message if it contains any. Please send
in plain ole text format and everything will go through.  Don't forget that
fancy signatures also contain HTML.  This is probably the number one reason
people have trouble posting messages to the list.

 

4) User unknown or invalid account

 

We have members who subscribe and then disappear. If you subscribe, please
take the time to unsubscribe before you vanish or change email addresses.
Invalid users are immediately purged from the membership ranks.

 

5) Duplication of message content.

 

If you are replying to a message, please snip out what your are responding
to and DELETE the rest of the message. This is common courtesy.  There are
hundreds of users on this list. Every unnecessary single word or letter you
keep in the message is multiplied by hundreds that the qth.net center has to
send out over the net. We all got the first message, there is no need for
you to resend the entire context again.

 

6) Electronic Bidding Sites

 

Please do not promote your own auctions ( ebay, etc.) on this remailer. This
is a QTH.net rule we have to live with. I have relaxed the strict rules of
no mention of ebay at all. If it is to the benefit of the group to ask about
an item you saw (like what is it?) then this will be permitted.

 

7) Flame wars will not be permitted. All involved parties will be
unsubscribed or put on moderated status.

Fortunately we don't have to contend with this very often.

 

8) Please keep on the topic of this remailer.  Off topic subjects tend to
upset a lot of subscribers. We don't want to run anyone off due to excessive
discussions that are not the focus of this list.

 

9) Spam filters. As the popularity of the web has grown so has the threat of
spam and viruses. The QTH.net guys have to tighten the noose a little more
every year it seems to parse messages before they are sent through the
system. Unfortunately in some instances harmless messages are rejected for
various reasons. I try to work with anyone having problems of this nature.
Just shoot me an email and we'll work through it.

 

----------------------------------------------------------------------------
----------------

That is about it for now. Again thanks for helping this list be a great
success. We have a very large and growing number of military radio
collectors & users around the world on the list. The knowledge base is
tremendous! Thanks to all who contribute.

I found I couldn't arbitrate a disagreement about the SCR-274N's modulator, 
the BC-456.  Had to RTFM & found it's a screen & not a "heising" plate
modulator

So comes the question about why Navy used high level plate modulation
in their MD-7.

Weren't the command rigs meant to run at flea-radiated power to be only 
heard in the aircraft formation?  If that was a design criteria & it seems 
probable, where'd Navy get off with the xtra AM oomph?

The B-57 Cambera, at least, used an IFF called a APW-11/RT-122B
that goes in a command rx parking place... right down to rear connector

But to prevent accidental plug-in, there were 2 spears in rear so
it'd only go in it's reserved parking place

But was surprised to see ARC-5/274N radio nests were still spec'd into 50s

BTW, the APW-11 is packaging triumph (mga?)  Some ten 7&9 pin miniatures & 
a lighthouse tube in that restricted real estate

And this APW-11 emerged from a country flea market.  If these things could
only talk

The manual gives some clues:  "Due to the use of plate plus screen-grid 
modulation in AN/ARC-5 equipment, the transmitters may be tuned for 
maximum output in the VOICE position of the control unit."  [As opposed 
to the usual CW tuning procedure.]  "This results in a slightly higher 
power output than in the corresponding transmitters of Model ATA 
equipment.  Modulation distortion resulting from improper tuning of the 
antenna circuit has been considerably reduced in AN/ARC-5 compared with 
Model ATA equipment." 

So, it would appear that improper tuning in the heat of combat was at 
least one driver.  I suspect that the Navy may have asked for two 
options in the original contract, for evaluation - status quo and plate 
modulation.  The difference in cost would have been relatively minor for 
the improvement in intelligibility under certain conditions.  By 1943 
Bell Labs had engaged in a great deal of research into improving 
intelligibility of radio and interphone equipment, so this output may 
have factored into the mix as well.  Also, don't forget that 
occasionally these transmitters had to be used to fill in for the 
liaison transmitter, so a little extra oomph was probably not a bad thing.

73,

Mike

Not just for in-formation talking.  There
wasn't much of that going on.  WWII
airplanes flew a lot of places overseas
and in the ZI.  The pilot/copilot talked
to air traffic control stations and other
stations.  Even in combat zones the radio
operator was more of a gunner than a 375
operator.  There were rules, and it seems
that every command had their own, when to
carry a radio operator.  Like over water,
on international flights, etc.  I wasn't
a radio operator, but I occupied the radio
position many times on this old C-47 we had.

I am confident he doesn't read at least any
milsurpus lists, altho his interest is strong at 
least in the nomenclature area. His website
listing of mil electronics literature is still up,
and it would seem a strong bet that he is a

Follow up:
Published by Marine Corps at San Francisco, Mar. 18
1943: "GF-11 / RU-16 INSTALLATION IN 75MM SELF-
PROPELLED GUN MOUNT HALF TRACK"

Mounted between driver and co-driver seat. No pix but 
sounds like a box, with door access to radio controls,
receiver and transmitter control boxes. Antenna base 
is MP-37 installed on mast base support bolded to top
of the beam above right hand door of the vehicle. 
Shift control level must be bent forward 3 inches to allow
room for shifting into reverse. Extension control box mounted
on wall behind driver, near driver's side gunner seat. 
Antenna is MP-49, MP-50, MP-51, MP-53. 8 receiver coils
and 4 transmitter coils provided.

Why did they choose this radio? Maybe they had an excess of
them, as more  274N / ARA-ATA equipment was going into 
aircraft. The gear did have a wide frequency range was was 
fairly  robust, at least more robust than a lot of other aircraft
equipment. HF use would let you listen to warning networks 
and talk to gun spotter planes.  -Hue Miller

The recently updated web site has charts
of typical NVIS Ham Bands, based upon
foF2 Ionospheric measurements.

The most recent chart is an example of
the NVIS ham bands for Central California,
over the past several days, based on the
foF2 measured by the Point Arguello Ionosonde.

At the present time in Central California,
our Best Ham Bands for NVIS are:
Local Time
60 meters Sunrise to Noon.
40 meters Noon to 2PM
60 meters 2PM to Sunset
75 meters Sunset to 2 hours after sunset
160 meters Night
75 meters Sunrise to 2 hours after sunrise

Also presented, is an older chart for UK
best NVIS ham bands based on the foF2 in
April 2006 as measured by the Chilton Ionosonde.

Both of these are good examples of typical
patterns of best NVIS ham bands in the
mid-latitudes.

If you click on either chart, it will take
you to the hourly world foF2 map.

Nope.  It has a PJ-068 plug.  As I explained in excruciating detail last 
year, that makes it definitely post-war, whatever else it is.  I.e., whatever that 
artsy-fartsy cutesy arte-nuveau element cover means.  

Actually I had one of the real post-war re-nomenclatured T-17's (but in very 
poor mud-soaked condition) and it doesn't look anything like that.  The 
element cover has radial vents and is about twice as thick as the standard cover but 
from the front looks about the same as real ones.

Robert, I must have missed that.
Many WWII sets use this configuration of plug;
 what's the correct nomenclature for a WWII or earlier plug
of this type?

Once more, into the breech.

The common audio plugs in service from 19 uhmmm to about 1949 were PL-54 
(black barrel stubby high impedance bale-out), PL-354 (red barrel stubby low 
impedance bale-out), PL-55 (black barrel general audio use) and PL-68 (microphone 
and LS-3 and whatever the field-coil predecessor to the LS-3 was).  The Navy 
had a similar run with both five-digit and NAF numbers.  

The red band around Navy nomenclatured 7/32" diamater PL-68 equivalents has 
nothing to do with this.  It was because of a change in Tip/Ring assignments, 
nothing to do with impedance.  Early production of RS-38's had the PTT switch 
on the ring instead of the tip.  You should check this before attempting to use 
an RS-38 with plug without the red band, regardless of what the nomenclature 
on the plug is.

Post-war, the Navy type numbers and NAF numbers were dropped and the PL- 
numbers all changed to PJ-0 numbers.  And a color indicator letter added to some.  
PL-54 and PL-540 (I never figure out what the difference was) became PJ-054B. 
 PL-354 became PJ-054R.  PL-55 became PJ-055B.  PL-68 became PJ-068.  And the 
bale-out female cable connector JK-26 became JJ-026.

So if it says PL- or JK-, it was made before about 1949 or it's a postwar 
copy and not military at all (these are mostly Japanese copies and very crudely 
made - Fair had a bunch of their RS-38's once and I had the misfortune to buy 
some).  If it says PJ-0 or JJ-0 it's definitely postwar.  -30-

Robert/WA5CAB is a reliable source.

The plug you describe is the U-7/U.  If you want to connect to the transmitter's transmit/receive relay contacts to mute the receiver and/or install the external "MONITOR-NORMAL" (netting) switch that was used in the military installation, you will need a 27-pin U-8/U (which also leads to the control box, if that is used).

I always understood exposure to high intensity audio at 18Hz caused involuntary contraction of the large sphincter with corresponding results. Just think what one Kw of 18Hz audio would do on the front line.

John,

According to "A History of Engineering and Science in the Bell System:
National Service in War and Peace", pp. 87-88, the Friis group at Bell Labs
in Holmdel, NJ developed a mortar-locator radar, type AN/TPQ-2.  The book
doesn't have a picture of the set, but there is a drawing showing how the
beams intersected the shell's trajectory.  I'll scan and post it ASAP.

Jack and the Group,
  In the not so distant (but now clueless) past,someone sent me a list 
of RF connectors with an explanation of sorts as to the origin of thier 
names,like SMA,N, C, BNC etc.I think "N" was Navy connector and "BNC 
was Bayonette Navy Connector.It all seemed probable/improbable at the

  And in addition, someone else sent me a link to a web site(now buried

of RF/Microwave adapters.Nickle plate and Gold.It looked very cool and 
probably worth $10,000 in actual cost if purchased from a US supplier 
like MA/COM,Weinscell, or Narda .(I think MA/COM bailed out of the 
business.Anyone know who supplies the Omni-Spectra/MA/COM line

	Actually, I ran across some other info along these lines. BNC actually means 'Bayonet Neil Concilmann.' It's named for the Amphenol engineer who invented it.

	'SMA' means 'Small Microwave Type A.' You can probably guess what SMB and SMC mean.

	Not sure about types N and C.

	Happy tweaking.

And then there is HN which a Type C that's threaded.

 From what I've heard in the past, the N was designed along the lines  
of the BNC, but more rugged, whereas the TNC is simply a threaded BNC  
from a mechanical/electrical point of view.

From: WA5CAB@cs.com

And don't forget the usually forgotten TNC, which is essentially the  
same as the same vintage BNC except threaded.

The GR 874 connectors are hermaphroditic (unisex) and mate w/ themselves.
For those interested in GR, there is a Yahoo Group about their gear:

  http://groups.yahoo.com/group/GenRad/


BTW, GR also made another (fairly rare) series called the 900. High
precision, but $$$$.

Umm...The TPS-1 was a "round and round" search set with no height finder 
capability. Height finders with "rocking horse" antennas in addition to 
the TPS-10 were/are the CPS-4, the FPS-6 and its various latter day 
permutations such as the FPS-90.

Message-ID: <000601c8710f$f440e180$650010ac@DEN3>

  I thought I'd let all of you know about an upcoming operating event next
week. You may remember Taigh Ramey's plea for help with an A-36 restoration
a while back and he's also mentioned on this list about a project involving
a flying B-24 Bomber called Witchcraft. I answered his call for help and
have been involved with both ever since. I leave for Florida where the B-24
is spending the winter on Tuesday 2/19. I will be getting the Liaison set
ready in the B-24 for its first flight on the national tour set for Friday
morning, 2/22. 

  I spent a week working there in January getting the radios installed and
will be tying up the loose ends on this next trip. We plan on operating the
radios on the ground Wednesday and Thursday night and possibly some during
the day. The first time in the air will be Friday 2/22 sometime between 9
and Noon Eastern Time. Unfortunately the flight will be short so we won't
get much in air operating time. This flight is just a test of the radios, I
don't know at this point when they will be back on the air next because we
don't have full time operators, nor do they have any temporaries lined up,
at least none I'm aware of. I guess you could say we wanted to make sure we
could do it before we got too far ahead of ourselves. I'll keep you informed
as the plan develops. 

  The main purpose of this email is to ask those who are interested to
monitor the frequencies I'm about to list and try and work us on the days
mentioned above. The call we will be using is mine, KB4DMF. My name is Steve
Williams and a friend of mine, Joe Fox, N4NYT will be along to help. Look
for us on or about these frequencies.  

 

Daytime, 7.290 or 3.880 MHz

Nights, 3.880 or 1.985 MHz

 

The mode will be AM phone. I wish I could say that we'd be operating CW too
but I'm afraid I'm way too rusty for that right now. Joe may try it, but not
me. I can't really pin down any times since we will be working and that will
take priority over operating. We should be on sometime between 5 pm and 10
pm in the evenings though. As I said before, the actual flight should take
place between 9 AM and 12 Noon. All times listed are for the US Eastern Time
Zone.

  For those of you who may not be familiar with the radio equipment in a
B-24, the transmitter is the BC-375 and the receiver is the BC-348. Both are
being operated with dynamotors, complete with carbon microphones and HS-33
headphones. We will have both the fixed antenna and the trailing wire
antenna when in flight but we will obviously be limited to the fixed antenna
while on the ground. The fixed antenna is too short to be resonate on 3880
and 1985 so we will have somewhat of a disadvantage on those frequencies
while on the ground. 

  The planes are owned and flown by the Collings Foundation. You can find
them and a lot more information with a web search. They also have a B-17 and
B-25 that will be starting the national "Wings of Freedom" tour along with
the B-24 on the same day.

I hope to do the same thing with the B-17 next winter when this tour ends.
The Collings Foundations website lists tour stops and dates if you'd like to
try and catch them when they are in your area.  

 

Listen for us on the air and I hope we get to work you. I would like to add
though that this is more of an informal test than a scheduled event.

 

Tnx and 73s,

KB4DMF

I wish they were going to be in the Northern Virginia area.  There schedule
shows them starting in FL and going to the left coast via the southern

Was there recently a thread here on this receiver, a 
modification and renomenclaturing of the BC-348 ?

If there was, i seem to have thoroughly deleted all
traces of it, and wonder if i was dreaming.

The receiver, which i recently bought, at first looks like
a kludge, with its large connector coming of the left front
panel and the differently-colored small box attached to the
receiver top surface, having squelch and noise controls.
It probably contains miniature sized tubes.

The fellow i bought it from said he thought airfield usage.
I thought likely; but Brad Whiting searched on the web
and found "R-589 / MRC-20" for Forward Air Controller
jeep. Note, R-589 in the online listing but the receiver i 
have is nomenclatured R-584. MRC-20 consisting of R-584
+ART-13A + ARC-27 + ARC-55, or as Brad pointed out,
"about 600 lbs. of radios". I wondered why a FAC would 
need HF, but then i thought, maybe just insurance, better
to have than not have. BTW, this particular example was
originally a BC-348-Q. It has an AC supply in it; i thought
oh darn, modified by ham. Brad pointed out that the PS 
looks much neater than the ham added supplies, i noticed
the supply uses bathtub oil caps and not lytics, maybe 
another sign of a real production AC PS, but of course no
idea when or where this was added. -Hue Miller

Ah yes - with the date, i found them all.

Also seen at Rickreall hamfest: AN/PPN-2 looking unissued and
complete. It was apparent the owner was proud of it, so i didn't
even ask if it was for sale or if so how much. I knew that multiple
hundreds of dollars for something that basically did nothing, was
not for me, "value for money".  Even tho i do have a conversion
article on it. You end up with a 220 MHz A2  short range sending-
receiving set, and this option is not attractive either.  -Hue Miller

He's hoping to find one of the many people in the world
    who have more money
        then they have good sense.
And he very well may.

You'd think, if he valued the thing so much,
he'd have had the butchery on the metalwork fixed
before having it painted.  Now that's all to do again.

>.....I wondered why a FAC would need HF,.....

Because, contrary to popular myth, HF in aircraft 
did not suddenly cease to exist during WWII.
It was in sustained, concurrent service for decades
afterwards, with many fields and aircraft exclusively HF,
especially outside the U.S. and western Europe,
meaning "most of the world."
And,. in fact, is still in use on overseas flights
to this very day.

Think the mortar-locator was AN/TPS-3.  This was a ww2 height-finder that,
per Sig-Corps V3 called "The Outcome," was found effective for pinpointing
mortar launch sites.  Pic there matches somebody's antenna description.

The few remaining were rolled out & employed in Korea.

AN/TPS-3 used 600 mhz pp-parallel Zahl tube.  The VT-158.  Look here

 From what I've seen in the late 40's and early 50's the
post-WWII AT-6's were equipped with HF only.
Something along the lines of the 274 I think.  Our control
towers and other ATC used 6440 and 4220 KHz.   The
one thing that can be said for aircraft VHF is that  there
were Squelch controls.

Hmmmm....just briefly, how's a long wavelength radar like that work on
very small target?

Also, i comment, this fellow's tube storage facility is not very confidence

Keep watching the tour schedule for updates. Nowhere near all the tour

see that they did go to Virginia both years, but much later in the year.

  I guess I should have mentioned where the plane is located now, and where
it's going for the first stop of the tour.

  Right now it's at the New Smyrna Beach Airport at a maintenance facility
called American Aero Services. Actually I believe all 3 bombers are there
right now. On Friday they will be flying to Keystone Heights Florida. The
B-17 and B-25 have been touring Florida since mid January but the B-24
needed more work done on her. She had new fuel tanks installed.

Ken Lakin KD6B was at the hamfest trying to sell his 
Chinese handcrank generators for the 102E set. He 
told me that altho Red Star has kept a low profile lately
he still has 102E sets to sell. Sez Red Star has other 
import business from China and so radios are just not 
a priority. Ken had for display a 1.6 - 5.6 backpack 
CW/ USB set. Had 4 freq switches, one MHz and 3 kHz
like the PRC-47. This thing was about half the total height
of a PRC-10. Ken said it actually had no nomenclature 
number on it, nameplate said only "USB Radio" or something
like that. He says Red Star seems to know a lot about 
the radios and their usage but not at the engineering level.
Said he got the "USB Radio" out by installments as the 
China gov't seems to prohibit its export as something ??
critical ?? Don't understand. He also described a "73 Set"
which seems to cover same freq as 81 Set but he describes
it as better radio. Also sez the all-in-one package 102E set
to be very rare. I think he also said the 81 Set backpack 
radio was impossible to net on CW; when you switch to xmt
(or recv??) the freq ends up offset by more than a few kHz,
as there is insufficient buffering on the trans. oscillator. He also
said the "USB set" in CW mode injects a tone, common enuff
system, tho in this set not a sinewave and so sounds on the air
like A2 mode, which may be a feature when working to AM sets.
However i was thinking, it seems with China radios there is always
a fly to be noticed in the soup. -Hue Miller

U.K. Man, Charged With Forgery, Bought Radios  



2.15.2008   


If you?re crazy for collecting old radios, someone might accuse you of having a touch of OCD.

But in one case, this was less of a laughing matter.

A newspaper in the United Kingdom reports that a 56-year-old man stole the equivalent of almost $30,000 from his partner, a 71-year-old woman, and spent it all on radios. He surrounded himself with them and often had them all on at once, according to the report.

He was accused of forging her signature on checks made out to himself while she was a resident in a nursing home. Police found about 50 wireless sets in his home. The defense said the man had suffered from an obsessive compulsive disorder for 30 years.

Yes, that is the radio. However in this photo, the microphone
is incorrect. Also with the radio was a headset. The whole

I bought 3 radios from Harry at Redstar and the 73B was one of them. It 
is a nice little backpack with analog dials (separate rcv & xmit) and is 
am/cw. None of the docs that came with show power output but current 
drain with 24v battery is 550ma xmit. It covers 1.7 - 6 mhz.

I've only ever seen pictures of the single unit 102E on Bill Howard's 
site. All of what Harry sold were the two piece units. It is also known 
as the S1031 as the docs reflect both model numbers. The receiver is 
available separately as the 139. It uses vacuum tubes but the two later 
versions (139B & C) are solid state.
I have the 139B which is a nice little compact receiver. Covers 1.5 - 18 
mhz.

Ken Lakin has one of the all-in-one 102E type radios and
described to me its construction. He also cited a nomen-
clature booboo where there are two sets numbered 81 - 
one is the backpack rig 1.5 - 12 MHz but i don't remember
what the other one is. I think their nomenclature system is
a mess. -Hue

Yes, once it's out of the country there's obviously no more problem.
Why the government is touchy about what gets out, is maybe hard
to understand, especially for stuff that's not quite state of art - who's
going to steal that technology?  Someone i was talking with, maybe 
Ken, was saying that China didn't want their gear to be found in some
war zone, like some with some rebel army in Africa, and China end up
getting blamed for abetting some civil war.  -Hue

Yahbut consider that the source was a UK tabloid.  Not known for their 
accuracy in placing decimal points.  Besides, if he bought them from the States, 
two-thirds of the cost would have gone to USPS.  :-)

When i was looking at the handcrank gens for the 102E
set, Ken pointed out the kind of blemished finish on the
paint on the generator. He said he could clean it up but
it would be a lot of work. He said it was due to the wrapping

Hi, 
 
I have a Wilcox Gay VFO as used in the ET4336 tx, with just a few wire  
changes it is now a 10W single tube CW transmitter. Could either be used as such  
or returned to VFO status. Will supply details of mods done so they can be  
reveresed. Set has its outer case. 
 
Originaly the vfo o/p was via a pin on the bottom of case. This had been  
altered by the military, plate states mod in 1962. I think was a Navy mod for  
some reason, likely better contact etc. 8 pin Jones plug on rear for lt and ht  
input, needs 6.3 and 500v, and key line and ae o/p.
 
?40 plus postage
 
cheers, Ben.

G'day list..... maybe not  appropriate for this list but I have a cross
reference list of HP transistor  and diode part numbers that may be useful
if  repairing older HP equipment.
The list was compiled back in the 80's and may not cover components in some
earlier equipment.
List runs to several pages single  spaced on A4
E.g a  HP 1854-0590 is equivalent to JEDEC NO. 2N3054.

No, i didn't make an effort at all to translate the pages.
Tom Bryan sez he wrote the seller in English and did
business. I didn't happen to note an email address or 
link. Tom also sez they have two prices, one domestic
and then an export price, which is about double.

I am curious, what is the approximate weight of the 222
receiver and does it have the same problem as other 
one-dial receivers, that is, rotten tuning rate above about
10 MHz ?  

I looked and stared with eyes bugged out at the neato 
sets, but you know what, i think i decided i had enuff
projects aplenty, and as Dave Stinson once explained,
you have to become ruthlessly true to your mission.

Well, it tunes 1.5 to 30 Mc in 5 bands:
1.5 - 3 Mc
3 - 6 Mc
6 - 12 Mc
12 - 20 Mc
20 - 30 Mc

The tuning rate is certainly faster on the top band, but not uncomfortably 
fast.

Receiver weight is 48.5 lb.  Power supply is 11.5 lb.  I didn't get the 
little do-hickey shown hanging on the right side.
Bandwidth is 0.4 / 1.5 / 3.0 / 6 Kc.  It has separate rf, if, and af gain 
controls.  The meter is mostly for diagnostics, showing a measure of cathode 
current for all the tubes, and heater and plate voltages.
Audio output is 600 Ohms to a speaker, or through an attenuator to 600 Ohm 
phones. (supplied, very nice)
Input voltage is adjustable from about 180 to 250 volts, 50-60 cycles.

FYI
Richard, AA1P

It's almost the same specs (everything except the freq response, 200-5000) 
but earliest through latest TCS manuals I have show 677N227 as the Collins part 
number (of that number type) for the TCS receiver output.

Subject: [Milsurplus] Coax Connectors
Message-ID: <000e01c874b0$cec14d60$0501a8c0@alltel>

After reading all the threads on Coax connectors, it got me thinking (dangerous)
and doing some research in my old texts and reference info.

N Connector, sometimes called "Navy" where it was used predominately
for freqs above 30 or so MHz.  Invented by Paul Neill of Bell Laboratories.
Comes in both 50 and 75 ohm designs.  Do not try to mix them, different
pin sizes.

BNC Connector, "Bayonet Neill-Concelman" connector, Neill worked with
Carl Concelman, an Amphenol engineer.  Concept came from work done
by Octavio Salati, in 1945, he worked for Hazeltine Electronics. Made in
both 50 and 75 ohm styles. 75 ohm models do not have any dielectric
or only a very thin amount on the inside.  Cable TV uses a LOT of these.
Have seen it called "Bayonet Navy Compact" and other names.

TNC Connector, "Threaded Neill-Concelman", same specs as BNC but
threaded attachment.  It also comes in 50 and 75 ohm styles. Ditto on
names used.

All are available in both Solder, Solderless and Crimp configuration.  The
crimp style is all we use in shop here.  And I believe is used exclusively
in aircraft installations, no solder joints to crack.

Major design simularity is you can cut off the attaching ring, bayonet or
threaded style and interchange all the types.  They have same interior
size.  All do NOT depend on the attachment for circuit connection, a 
true coaxial connector.  Much different than convention UHF/Mini-UHF
which are terrible connectors unless very tight.

Just my input, be it useful or no.

Hi all, 
 
I know the TCS has been covered over and over but having recently acquired  
another one I am now going through the testing procedure once again. Its been  
some time since I messed with the TCS I already had, its just like going back 
to  school, hi. 
 
Anyway, I have the tx going, damaged meter and new relay fitted. While  
testing it I was using a croc clip to ground the keying line at the front jack.  I 
noticed there is quite a spark when the contact is lifted, ie the back emf off 
 the 2 relays must be quite a bit. Thinking on the fact the set is CW keyed 
via  these relays then even at 12 to 15wpm there are going to be quite a few 
clunk  clicks on them. Has anyone (bothered) to fit either a reverse diode or an 
RC  filter across the key line ? to help suppress these clicks and back emf  
voltages? or should one just get on with it ?
 
I do intend to bypass the ac mains on/off switching in the tx and control  
box, I'll fit a decent on/off switch to the psu chassis and disconnect the ac  
feed up the leads. I don't like the idea of 240v ac going through the various  
cables, not 60 odd years on.

In principle I never modify any original military radios. It's good  
enough for me if it was designed a certain way, and I want to keep it  
the way it was originally issued, operated and maintained.
If I want to mess with a circuit, I'll either build something new or  
will do it with an otherwise unrestorable piece of equipment.

Never had a problem with any TCS keying circuit (I've been using them  
since 1964), and cherish the keying characteristics/tone of each type  
of surplus transmitter. This is the tone that was heard when the  
equipment was originally used.
The only thing which makes the TCS weird to use is the lack of sidetone.
I rectify this problem by using an original LM-18 (Navy version of the  
BC-221 frequency meter) to monitor the transmitter frequency.

As to not using the control cable for switching the mains - if the  
cable is really in bad shape, it's justified, but if it was me, I'd  
just use a power strip or outlet with a line switch instead of  
modifying the original control box/PSU.

This is my opinion and way of treating surplus equipment. Your mileage  
may vary...

Ben,

There were two TCS's (don't recall the model number) in service aboard USS 
Valley Forge (LPH-8) when I got off Active Duty in November 1968.  They were 
installed when the ship was commissioned in 1946 and while I was aboard got used 
at least every time we got underway and until we dropped the tugs and cleared 
the sea buoy.

As far as pulling the AC from the receiver power cable is concerned (there is 
none in the transmitter cable) don't forget that it and the transmitter cable 
both have 230 VDC on some of the wires.  Having forgotten this, I once spent 
a full day trying to figure out why a receiver on the bench was deaf.  No 
screen voltage on a 12SK7 will do this.  :-)

I picked up this RCH from a buddy who used to collect Navy stuff, but he 
said he'd never had it powered up.  It incubated in my garage until I 
got around to lugging the 69 pounds (of 109 total) chassis down to the 
bench, but to my surprise the caps reformed nicely and it came up 
working like a champ.  It's an 11 tube superhet built by EH Scott, for 
Navships and based on the blank "placed in service" nameplate I'm 
guessing this one may have spent its career in a warehouse.

What was the RCH used for?  I know Scott made "entertainment" receivers 
that could operate from AC or DC mains but the RCH is a really heavy, 
very ruggedly constructed set with a 120VAC power supply and BFO.   
Since it has both LF and HF coverage, skipping the BC band I'm assuming 
it was a communications receiver,  but the geared flywheel tuning sure 
makes it a great SWL band-scanner.   And it's hot from the longwave 
beacon band all the way up to the 17meter shortwave band.

Another question - the "Gain" control is a ganged pot that adjusts RF/IF 
and Audio gain, but even at minimum position audio is still quite loud.  
Was this by intent?

Ben:

I have done that.  The only effect I notice is that it lengthens the 
relay "on" time
by a few milliseconds (not measured).  The "back EMF" spike, when 
shorted by the
diode, appears to keep some current flowing in the relay coils, 
thereby lengthening
the ON time slightly.   It does not present any problem with 
operation.  If you are using a
BUG or keying device you might want to lighten the weighting compared 
to what you
used prior.

Have fun with the "old reliable" TCS.

Bob,

According to the manual, it was primarily intended as an entertainment 
receiver but good enough to be a backup for the communications receivers aboard (at 
least when it was new).

It's been 39-1/2 years but I don't recall not being able to turn the volume 
all the way down on the one we had aboard.  I just took a quick look at the 
schematic.  Check the audio gain pot.  My guess is that you've lost the ground 
connection at the bottom.

Of course. Circuit theory says the time constant of an R-L circuit is
L/R. Also the constitutive relation for an inductor is V=L dI/dT.

If you put a diode across the coil of a relay (an inductor) the current
(and hence the force holding the relay armature) decays as L/R, where R
is the total resistance in the series circuit (= Rcoil + Rdiode) The
Rdiode is usually negligible.

If you put nothing across the keying contacts, the voltage across the
coil increases until the air breaks down and then drops to the voltage
across the sustained arc. This is likely to be hundreds of volts,
dropping to tens of volts.

So, in the case of a diode, the current decay will be much slower, so
the relay will stay pulled in longer.

If you want to suppress the key sparks, consider a series R-C snubber.
The C is chosen so that the stored inductive energy (1/2 L I^2) is
roughly equal to the stored capacitive energy (1/2 C V^2), so on contact
opening, the inductive energy transfers to the capacitor. The series R
is to limit the current through the key contacts and damp the LC
oscillation in the keying circuit.

Best,
-John

Maybe one of the caps didn't reform as well as hoped. I had this happen on an
ARC-5. You couldn't build up enough voltage to bias the cathodes to turn down
the gain.

No.  Your point could be valid if the RCH were like the Command Set receivers 
which have no audio gain control.  But look at the RCH schematic.  Box stock 
audio circuit for almost all WW-II ground and shipboard receivers except that 
some separate the audio and RF gain pots (like the TCS).  The audio gain pot 
sits between the output of the 6H6-GT detector and ground.  The wiper goes to 
the grid of the 6SQ7-GT first audio.  The cathode of the 6SQ7 goes to ground 
through a resistor.  No sort of feedback or other connection to anywhere else in 
the circuit.  With the audio gain pot fully CCW, it wouldn't matter what the 
condition of the capacitor across the cathode resistor was.  No input equals

Have you solved drift and FMing issues when using
the 375 on 40 meters?  I got mine to stop FMing,
but it still drifts down 1 KC+ after key-up.
I'm going to try to get mine going and see if I can 
talk to you, 375 to 375, although the distance at that 
time of day seems tough.

I have updated the directions of modifying the PRC-47 for fine tuning in 
frequency. The new modification instructions can be found at the URL below.
The reason for the update is that I had the wrong resistor marked in the 
photos of the modification.
The original modification worked and was very stable but the new revision 
will give you more frequency swing.
I have never made any mistakes before on any of my modifications  and 
probably will never make another mistake.     :-)
I do apologize for this minor error.

For those of you who may be wondering where we were today in the B-24 and why we weren't on the air; To make a long story short, the plane lost it's #4 engine in some sort of FAA Pilot certification test so the actual flight didn't take place. They are replacing the engine now and we could be on the air as early as Saturday morning but afternoon is more likely. Cant say for sure, but I will post something here if I have the chance. Just look for us anytime you can on 7.290 AM phone. 

Later,

Nice photo you found, Lloyd. Interesting, what year is this?
Looks like leftmost SCR-183 rec and xmtr are paired. 
Apparently no liaison receiver other than the single SCR-183
receiver and the SCR-240 ( ? my guess ) receiver next to it.
That apparently worked with the BC-191-AA ( my guess ) on
the floor. Het freq meter ( my guess ) on desk. I wonder where
the BC-191 antenna lead went to? To trail antenna only? The
SCR-240 and SCR-183 sets to the right seem to have their
antenna leads go right outside.  -Hue

I also noticed that altho there's a grinder hanging down with
the other control boxes, both the SCR-183 receivers are set up
for local control. Interestingly, the rightmost SCR receiver has
a tuning shaft extension over to (what i call) the SCR-240 
receiver, so that the SCR-183 receiver local tuning knob would
tune both, or better said, this one knob serviced both receivers.

Yep, yep.  Not too many pictures show this so nicely.

The SCR-240 was a whole 'nother kettle of worms, a channelized set
(transmit and receive) built by Westinghouse(?).  On the other hand,
the receiver on the right's antenna seems to go through, not parallel
with, the box next to it which itself has a case that resembles a
mirror image receiver or a kitbashed SCR-A*-183 transmitter &
receiver.  An early frequency converter?

Just to add to the fun, while both receivers have local control knobs,
there is a coffee grinder under the shelf holding the set on the left
which implies yet another receiver somewhere aboard.

There certainly are plenty of SCR-A*-183 tuning units under the desk
and that big box to the left of it is undeniably a BC-191 of some
stripe.

Hue, I think you're right about the freq meter.  It's definitely not a
BC-221 predecessor though.  Its power supply may be one of the boxes
under the desk to the right.

*sigh* ... Yet another mystery for The Book.

Best regards,

This was the XB-15, 1934 vintage. I recognize some of the pieces but do not 
immediately id by number. The long tube coming down from ceiling with meter 
mounted to left of it is part of the DF system. The loop is just barely 
noticable in the exterior pix of the plane, plus the shadow of it confirms 
it.

What's that box shown partial just to the left of the
BC-191 ? Is that some kind of antenna tuner for it?

And the large column coming down from the roof?
Is that for the DF antenna loop?

Interesting: my original note read,

"Lloyd, m a n that plane has a m a s s ive wing area."
But QTH net's s mu t detector found something wrong
and bounced that and 4 retries, until i deleted that word
or words.... ( I didn't space out the letters to words like
this in the original, i did it here to elude the sm u t

Recomend it? Depends on your interests. Is a nice 78 page pictorial history 
of Boeing. Lots of specs but no production numbers.
The book is 4th ed, 1977. Paperback. Had never seen it before. I have a 
rather large library of aircraft material, however except for company 
histories, it is civil aircraft slanted. Also collect civil aircraft radios 
and books etc. Also old electronic books and catalogs that interest me for 
one reason or another. Then there is the weapons book collection, and my 
wife's car book collection and and and.

A little follow-up on this...

Robert,  the ground connection is intact and ohmmeter checks on the dual 
pot are as you'd expect.   I finally printed the schematic I'd 
downloaded from BAMA and taped all six pages up so I could follow the 
wiring and verified both the AF and IF/RF sections of the pot are wired 
correctly and see no signs of modification.  However, contrary to your 
very logical observation above, the audio bleed-thru is still quite 
loud, and is unchanged even with a clip lead from the  grid of the first 
audio tube directly to ground.  In fact, audio can still be heard, 
although lower in volume and with distortion, when the 6SQ7 first audio 
tube is removed from its socket!   With the tube in, the audio level is 
unchanged from zero to about 9 or 10 o'clock, then it increases to what 
sounds like the specified 2 watts.  By the way this bleed-thru is only 
audible in the MOD position, with the BFO on the audio indeed goes to 
zero at full CCW rotation of the gain control.   So it seems there is a 
secondary path by which audio is reaching the audio output stage.

And so, head-scratching continues!

That's actually a BC-AA-191, which doesn't have the built-in
antenna tuner like the later BC-191 or -375.
The box you can barely see to its left and above and
left of the T-17 microphone is the external antenna tuner;
don't remember the nomen at the moment.  
There's a spare one stowed under the table on it's side.
Wonder if they failed a lot in flight?

The box under the SCR-183, at the back of 
the operator's table with the large, graduated center knob and
two smaller knobs is an external oscillator, which is feed into the
antenna of the BC-229 receiver to provide a "BFO"
for CW reception- no kidding.  I have one here.

Thanks for the great photo.

Put a scope on your B+ lead and screen leads.
See if there is audio impressed on the power supply busses.
If so, find your open bypass.

Message-ID: <8CA451333C12207-7F4-F812@webmail-nd21.sysops.aol.com>

Greetings All,
 I am looking for a few bits for a current project:
  VOL knob for A.R.C. C-57 control head.This would be a black painted 
plastic knob but able to be illuminated from the edge lit panel.Looks 
like the knob found on our familliar command set control boxes.
  Also looking for the connector for the C-57.This is a similar 
configuration to PL-151, six position plug but with a key at 12 
o'clock. (The PL-151 will work).A picture of this plug is on the Fair 
Radio website but they do not list it as available.
  Manual that would be for or include A.R.C. R-22.This is the grey post 
WWII broadcast band navigation receiver.
 And I'm not holding my breath on this one: a 2-3 ft spline cable.
  Any suggestions for mounting a control head that has those mini Dzues 
(sp?) fasteners.Source for rails or other ideas?My media is plywood to 
build a small portable display. A previous project that someone else 
started and I finished had removed the Dzues fasteners and used wood 
screws.I prefer to not molest the control head in any way.
 Thanks,
            Jay KE6PPF

Indeed, and to conclude this chapter of the tale of the RCH  that 
wouldn't shut up...

Dave Stinson was correct in that it was a bad bypass cap, but not one of 
the decoupling caps - the common screen supply which I figured to be the 
culprit turned out to be clean.  It was the cathode bypass cap on the 
6SQ7 detector/first audio stage that was  letting the cathode bounce all 
over the place.  This tube or it's miniature or loctal equivalent was 
commonly used as 2nd Detector and first Audio in receivers as it 
contains both a high-mu triode and a pair of diodes, sharing a common 
cathode. 

But wait a minute...don't the books (at least the Ghirardi and Johnson 
book that I consulted) say that cathode bias cannot be used for the AF 
stage, and don't all the typical receiver schematics show the cathode of 
a 6SQ7 tied to ground with either fixed or self-bias at the grid?   
Well,  the RCH designers went with a separate 6H6 Detector and only use 
the diodes in the 6SQ7 to rectify the AVC voltage, so they were able to 
go with cathode bias, which (when properly bypassed) works just fine. 
But with the bypass open, rectified output from the AVC diodes was 
making it's way into the plate, regardless of what was happening with 
the triode grid.

Thanks the the help guys, always good to have to have to think a bit.   
It's a nice receiver, hard to beat tuning with gears.

	Allied Electronics has one of the best selections of Jones plugs that I've ever seen. I would be surprised if they don't have what you need.

	http://www.alliedelec.com

	More specifically: If your friend is looking for a socket with a 90-degree cable exit type hood, they should order Cinch P/N S-330-CCE. If a straight exit is desired, they'll want S-330-CCT.

	This assumes that you're dealing with a 30-contact connector (per the ASCII drawing you posted). I would add that Allied shows both numbers in their catalog, but one is displaying a 10-week lead time and the other bears a minimum order of 500 pieces.

	At least you've got part numbers to work from now.

	Happy hunting.

Does anyone have the specs on a DW-44 RF Ammeter made by GE? What's it
from and, more importantly, does it have a built in thermocouple and is
the meter movement internally isolated from the antenna  line?

Thanks,
-John

This page 

http://jptronics.org/radios/Military/prc5/prc5.6.pdf

has a MARS document on mods to the PRC-5, from a 
minimum of changing the osc tube and neutralizing the
6L6 PA to a full blown hackover. I cite this page because
i found it interesting to read about some operational problems
inherent in the PRC-5. You have to wonder if the radio was
actually used in service, that is: outside of training.

Subject: [Milsurplus] B-24 radio report
Message-ID: <000b01c87813$68da2e20$650010ac@DEN3>

  Well I thought I'd let everyone know how the B-24 radio project went. It's
been 48 hours now since we were on the air and no one has indicated that
they heard us.

 We were not able to work a single station while in the air. We had two main
issues; the first being that the leads coming to the cockpit from the
magnetos from each of the four engines were no longer shielded. They were in
1941-1945, but the shielding had been removed at some point for whatever
reason. As I understand it, they were used to ground the mags to kill the
engines in the event of having to ditch the plane in an emergency. We
learned this late in the week and way too late to try and do anything about
it.

  That limited our use to 40 meters where the ignition noise was less of a
problem but still very noticeable. Had we of gotten on the air in the late
morning or around Noon like we had planned we may have been more successful
too. As it were though, due to the engine change I mentioned in earlier
emails, we didn't get airborne until about 3:45 PM Eastern Time Saturday and
that's the basis for our second issue. (We were originally scheduled to fly
late morning Friday.) We started calling around 4 PM and that was prime time
for foreign broadcast, at least where I was sitting anyway. We stopped
transmitting at 4:30 PM. (Way too little time):-) I finally just decided to
yell my head off on both 40 and 80 meters in hopes that someone might hear
me and let me know later. It was very apparent that I wasn't going to hear
them. Let's not forget the noise level of the 4 1200 HP radial engines
either.

 If anyone heard me and tried to answer, I couldn't hear you for the noise
and foreign broadcast.  If you were in Florida or the surrounding area, I'd
say you had the same problem I did. If any of you heard me at all, I would
very much appreciate you letting me know. I was using my callsign, KB4DMF,
and also indicating that we were in a B-24 Liberator and her name was
WITCHCRAFT.

  The one cool thing that did work very well though was the trailing wire
antenna. None of us had ever reeled a wire with a lead weight out of the
belly of a bomber so we weren't real sure just how it was going to behave.
It was actually one of the smoothest, most stable things you ever seen.
We actually watched it through the open bomb bay doors. 

 We flew from New Smyrna Beach Florida to Keystone Heights Florida and the
highest we ever got was around 1500 feet. That's still a long way down when
you're looking through those open doors. :-)

 As for operating the radios on the ground at night like I had hoped to, we
had a few problems there too. The main one being that there was more work to
do in prep for the flight than we had thought so less time for play. On the
night that we did have time, our roller inductor crank and dial seized up on
us. We were there till 1 AM that night getting it fixed. No matter what you
do to old radios, they're still OLD radios!! We did manage to make one
contact with N4VMY back here in Kentucky on 40 meters Thursday night.

 I'd like to thank everyone who replied to my emails telling me you'd be
listening or trying to work us. Like I said in the original announcement,
this was more of a test that a scheduled event. It just turned out to be a
lot more of a test than I had hoped it would. We learned some things from
the test though and I'm happy to say that it ain't over yet. We're already
working on solutions for the problems and will certainly try again. I've
even thought about brushing off the old key and starting code practice
again. CW would have probably been much more readable under all the
circumstances. 

Once again- If you heard me, please let me know.

Later,
Steve

ANy possibilty the RF ammeter is from the AN/ART-13?

The scale and model sound right, but I can't see enough detail
in any on-line -13 photos to verify.

Thanks for the effort, it great to see equipment used in its original configuration and in a historical setting. 7.290 is great early in the day before the international junk comes on the air, myself I spend a lot of time on 7.290 running the old TBW and am amazed by the ever increasing number of Hams running antique gear. have operated several people running ART-13/BC-348 set ups but nothing older yet at least in Military equipment. Once again thanks for the effort and maybe you can take some pictures and post them on line.

The #222 receiver has taps and adjustmets for 180 to 250 volts 50/60 cycles.
I run mine off 240 volts and it works fine.

I can look at my PSU and also I'll check in all my original manuals

Is it possible that a previous owner modified it slightly?

Ben,

I hope that this gets through.  Everything I posted yesterday bounced.

The TCS-13, -14 and one order of TCS-12 were supplied for use in small craft 
and vehicles and only shipped with one of the dynamotor supplies.  So that's 
all that the manuals cover.  I have manuals on 10 of the 15 number models, 
missing -1, 2, 3, 5, & -8.  The early models were only supplied with the 20218 
115VAC supply but it contains an S301 otherwise the same as S501 in the 20242.  
The TCS and TCS-4 manuals show the switch connected to terminals 1 and 2 on the 
transmitter HV transformer.  The text says that S301 (501) selects between 
400 and 450 VDC for the transmitter but nowhere in the installation or operation 
sections does it say when or why you might select either.  The TCS-6 manual 
still shows the switch wired to 1 and 2 but it is not mentioned in the text.  
The TCS-7,9,10,11,12 manual shows the switches connected only to terminal 1 
(that's the schematic that you have).  So sometime during production it was 
decided to eliminate the 450 VDC choice but possibly so that they wouldn't have to 
change the nomenclature of the supplies they left the switch in place.  

In any case, it does not appear that you would hurt anything if you moved the 
450 end of the switch to terminal 2.  On my TCS-14 I normally run the 
PP-380/U.  Years back I bridged the transmitter filter capacitors with additional 
capacitors that boosted the high B+ to about 450 and the transmitter still seems 
to have adequate drive to load to 200 ma.

replies include:

The TCS  and TCS-4 manuals show the switch connected to terminals 1 and 2 on 
the  transmitter HV transformer.  The text says that S301 (501) selects  
between 400 and 450 VDC for the transmitter but nowhere in the installation or

and 
 
The TCS 6 manual schematic shows the switch arm tied to the  line
connected to pin 1 of the other transformers, and the two  switch
fixed contacts going to pins 1 and 2 of  T502.
---------------------
 
so, thats clear then. I think I will go ahead and connect the switch to pin  
1 and 2, I have no fear the higher voltage will do any damage. 
 
Many thanks for the info.

I have come across a puzzle on RF Ammeters.

The ART-13 uses a TC meter with 5 A FS and the ARC-5 uses a TC meter
with 10 A FS, yet the ART-13 is a higher power Tx. There is a current
transformer in the ARC-5's BC-442, but it seems to be a 1:1 ratio.

Is the RF Ammeter in the ART-13 somehow not in the antenna line (but at
some higher impedance point in the circuit) ? I don't have ART-13 prints
to hand

Hi John,

In the art13 manual, T.O. 12R2-2ART13-2 dated 30 March 1956, the rf 
ammeter (M101) is a GE 8DW52AAR84. It is an internal thermocouple type, 
0-0.25 amperes with a 20X expanded scale. Freq range is 0-20 Mc. It is 
coupled to the output of the antenna vacuum relay by xfmr T102 which is 
used as rf meter coupling. No specs on the coil other than iron core, 
single turn primary, single turn secondary.

Bob Miller has kindly pointed out to me that the ARC-5 meter is NOT
calibrated in Amps, but in arbitrary units. Mystery solved. Thanks.

I don't understand "0-0.25 amperes with a 20X expanded scale".  Do you mean
the meter movement is 0.25 A DC and the TC produces .25 A in the meter DC
circuit with an RF current of 5 A ?

The 1:1 transformer is clearly a current transformer, used to isolate the
meter guts from the high RF voltages on the antenna line (as in the BC-442).

Best,
-John

Don't know for sure but that's what the manual says. Being a TC device 
it will work with dc current as well so set up a load with known E/R and 
see what happens.

(a) I don't have an ART-13 or even a meter, and (b) the DC won't go through the
current transformer...  you'd have to have a high current RF source.

Robert Downs opined a 20:1 ratio on the transformer ( it's wound on a Steatite
bobbin, not a magnetic core), but I'm no so sure. A 250 ma FS TC RF ammeter would
be very delicate.

The original question was if the referenced meter needed an external shunt and /
or current transformer and, to that end, I was trying to ID it's original
purpose.

Best,
-John

John,

Bruce was merely trying to say that (assuming that the thermocouple is still 
good) you could confirm the full scale sensitivity of the meter itself with DC 
just as well as with AC or RF.

But no (I realized I wasn't certain of the correct spelling of "au 
contraire"), a 250 ma full scale meter is not very delicate.  It's quite robust.  20 ua 
movements are delicate.  And the fine print on the scales on almost a dozen 
RFA's of three or four different makes removed from ATC and AN/ART-13 
transmitters that I have all clearly say "250 MA FS".

The answer to the original question is yes.

Sure, you can confirm the sensitivity of the meter itself, but if, as
you say, the transformer scales the current, the combination must be
measured at RF.

My reference about delicacy was not in reference to the meter movement
itself, but to the TC assembly.

TC RF Ammeters almost always have very low resistance (hence high
current) movements because the thermal EMF is millivolts. You need a low
movement resistance to get the number of ampere-turns needed to deflect
the pointer with the low voltage from he TC.

If the meter has an internal TC and the dial says 250 mA full scale, end
of discussion. ( I wonder how they made a TC assembly for that low
current.) Therefore transformer must scale 20:1 in current. As I said, I
don't have one.

The bottom line is the questioner needs to test his meter by applying DC
very gradually to find out what it really is. No shortcuts by IDing the
gear it came from.

Thanks,
-John

G'day all,

I have had this receiver for quite some time now but so far, have not be
able to locate any information to enable me to repair it. The previous owner
apparently applied 24v to it whereas it should only have a 12v supply, I
believe.

It is a small synthesised receiver that apparently was fitted into a
portable TADDS (Target Alert Data Display Set) unit which I believe may have
been a GSQ-137.

Does anyone have a manual that actually covers the receiver section or at
least schematics of the receiver? If so, please contact me off list at
davprin1@optusnet.com.au

Thanks for looking

" T.O. " sounds like a USAF designation. I think the RCAF manual is
designated " E.O. "

No, Army Air Forces.  USAF didn't exist.  You may be correct about what the 
RCAF called their manuals but the copy I have, like the copy on the AT-1 and 
AT-7, is an AAF Technical Order.  -45- indicating non-US nomenclatured equipment 
(commercial or foreign).

I have a T-17-B microphone with a plain, unfinished
aluminum "collar" around the microphone element
speaking area, with what looks like room for a standard
F-1 carbon element and a punched metal grill with a lot
more holes than the standard T-17. This does NOT look
like a hammified unit. Was this some kind of aftermarket
user modification?  The cord is grey - don't know if that 
is original either. -Hue Miller

Sounds like it was a mod by a ham with some machining talents...heh.

Never underestimate what one can do with a Bridgeport milling machine 
and a decent lathe...  :-)

Okay, i'll take Mike's and Michael's word for it.
To me, looks too pro, overdone for a ham job.
Even the 3 fasteners are matched pan heads.
But- i've not seen another one, so very possibly you are
right. BTW, the last 3/8" or so of the stem where the cord
exists thru the coil spring, this is grey painted brass, in
contrast to the stem itself, which of course is black plastic.

I am looking for a lid for an AN/USM-25D boatanchor signal generator.  Is
there an orphan lid out there needing a good home?  I am also looking for
some of the attachments.  I use an AN/USM-25D to align my R-390As.  Please
reply direct.

Dave, if you get real stuck, maybe let me know. 
I have the RCAF manual, dated 1955, imagine that,
altho production of the hardware was only WW2.
Also altho the manual is Large, like RBC size, and
has not been disassembled for copy. Also kinda 
interesting that apparently the RCAF kept them on,
instead of buying some surplus ART-13s as the 
airlines did.

The configuration  is interestingly different from our
amphib radios. The GO were about 350W input CW
only, and single channel. The same plane model,
the PBY, in RCAF configuration, carried 2x AT-12 HF
and a single AT-12 LF. The transmitter runs about 
250W input under cw AND am. ( But i think the modulator
/PS must be super rare.) The control box switches 
channels between the 3 transmitters. 

Does the 1625 have the same basing as the 814? I was
wondering if need be, or preferred, if 1625s could be used
in the PA of this transmitter. Altho 1100 volts is not that 
much more difficult to scratch up than 500 volts. -Hue

Hue,

You forget that some hams are professionals or as good as professionals if 
their actual profession is unrelated to military radio.  Not all are hackers, 
although a visit to any flea-market will usually lead anyone to believe 
otherwise.

There was in fact a late 50's or early 60's variant of the T-17-on-steroids 
made that looked somewhat like what you described.  But it did not have a 
chrome-vinyl cord.  Tthe T-17-B which is what I think you said this one was marked 
as was built by Shure in 1943 and 1944.  The only example of the late variant 
with the large ventilated retaining ring that I've ever seen was in such poor 
condition that I was unable to read all of the nomenclature, but it was 
M-something.

I think later on i'll disassemble the collar device
and see if i get any clues on its origin. Yes, it is
-B, and contract dated '44. There is no chrome
anywhere. The collar is aluminum, unpainted.
Maybe it was made for "Highway Patrol" (the
TV show.) -Hue

I once had a T-17 lookin' mic that had a much larger than usual mouthpiece
diameter.  Probably easily enuf for an F1 element.

Alumunum very oxidized & bakelite w/o lustre.

Looked like T-17's daddy.  Perhaps a BC-AA-191 accsy or employed on it's
one-band forefathers.

Had it sittin' on a fleabie table & some guy went nuts & paid a lot.

Think I shudda kept it

Russ IL-14 plane (similar DC-3 ??? ) destined to become

i'm sure its next stop after restaurant service will be scrap.)

Doubt if I would want to eat in their with all those radium loaded instruments and radios. Examples of the Russian ART/BC set I have seen are loaded with radium paint, would assume all their labels on control surfaces and instruments are hot too.
