Charlie, et al

Here's the story.  The engineers at Hallicrafters before the War who were
designing the HT-12 that eventually became the BC-669-A decided that they
needed a connector about the size and number of pins as the AN 310n-28-8x
but they decided that they needed five #12 contacts instead of two.  So, as
they did or had done several other times before and since, American Phenolic
(later Amphenol) modified the inserts so that pins A, B and C took #12
contacts instead of the original #16.  The modified connector was
re-designated as AN 310n-28-767x (where "n" is a digit that designates the
metal shell type and "x" is P or S, for gender.  And the modified connector
has 7 #16 and 5 #12 contacts.  "PF" has nothing to do with the modification.
P means Pin and F means Fixed (non-rotating) contacts, which was an option.
Unfortunately, the -8 is molded into the inserts so they just left it.  Some
later production has the correct numbers stamped on the nose of the cable
connectors and the square flange of the chassis connectors.  But I haven't
seen but a few examples.

The standard 28-8 connectors may still be in production, but the 28-767
hasn't been made since the Korean War..  It is possible, assuming that you
have extra pins or sockets, to modify a 28-8 to a 28-767 but the depth of
the holes for the females is critical.  And if the source connector was a PF
or an SF, the contacts in the modified contact holes will not be fixed.

On the $95 for one new connector, most of you guys are 'way out of date on
military circular connector prices.  $95 is probably at the high end of the
going price new for a circular connector without rear insert contacts of
about the 28 shell size these days.  So my guess is that he looked up the
recent new price of an AN 3108-28-8S or P (not knowing that the one that he
has isn't that) and quoted the book price.  When I have them, I've been
getting $35 for the cable connectors (same as for U-7/U and U-9/U) and $25
each for the chassis ones.

Happy New Year to everyone!

Subject: [Milsurplus] 28-8S Mystery

I have a BC669 and power supply waiting for me to restore it, something I
will start when I get caught up on a couple other things first.  So, while
it waits I have searched for the elusive Cannon 28-8S to mate with the rig.
The modern Amphenol 28-8S does not match the WW II layout.  Low and behold,
a 28-8P came up on Ebay, and the seller said he had the mating connector for
it.  He wants $95, ouch big time, but a close examination of his pic showed
it to be 95% correct.  There should have been 5 larger diameter pins laid
out like a pentagon in it, but it only had 3, it was missing the two on the
end of one row.  I looked at a picture of the other end that goes to the PS,
and it seems like it only has 3 large pins like the one he is selling, but
from the pic, it is hard to say, but somewhere along the line, my PS had
that connector swapped for an octal, so don't have one to compare to.  So,
now there are 3 iterations of this plug and socket. I wonder if the fact
that the writing on the male connector on the BC669 says 28-8 PF is
indicating a special type that is in the truly unobtanium category.  I have
run across another fellow who has been searching for 7 years trying to find
one with no luck.  Guess I will have to either change it out on the 669, or
using pins that fit and epoxy a home made connector body for it.

Yes. I believe that many WWII firearms are "Curio and Relic", but one should 
check each one for this. The C&R group has many advantages over those 
which are not C&R.

	No, heres the C&R def from ATF:

	Firearms automatically attain C&R status when they are 50 years old.
Any firearm that is at least 50 years old, and in its original
configuration, would qualify as a C&R firearm. IT IS NOT NECESSARY FOR
SUCH FIREARMS TO BE LISTED IN ATF'S C&R LIST.

That is very interesting. I didn't know there were any in the continental USA. I wonder what the power of this station was.
There was an Army training base out here in western Oregon,  Camp Adair, which at its peak had a population of tens of thousands; I think it was actually Oregon's "second largest city", but even with that size, I
have not found any evidence there was any kind of broadcast station there. ( But it started at only about 7 miles outside of Corvallis, Oregon, which did have radio stations. )

Many years ago, I walked the halls of an Army hospital at Ft. Lawton, WA, with a transistor radio trying to find out where station "KURE" was. These were the one-story long, wooden buildings with numerous rooms off the
walk-through hallway, almost a kind of "shotgun shack" construction, and these buildings were all linked together, so you could walk for a long time. Some of you will remember that style construction. What I eventually
concluded was that "KURE" was a "wired broadcast" operation. I was a youngster, and didn't know much. I also recall out at a very small town on the Olympic Peninsula, trying to figure out where "LaPush Radio" was
located. I finally figured out that actually  meant "LaPush Radio Repair".

Camp Adair is now gone except for just a few buildings and a natural wetlands park.
Fort Lewis, right in Seattle, became a park. Still has a large radar installation, Army cemetery, and a couple buildings.

>Subject: [Milsurplus] AFN in the US

Does anyone have any information of AFN (Armed Forces Network) operations Stateside during WWII. There is plenty of info available for overseas ops in Europe and N. Africa  but information on  US station operation is scarce. Evidently there was a station in operation at Ft. Dix under the call sign WDIX.

Thank you, Jon. :-)

Lessee....I am 77, born in 1942. WWII ended in 1945. That Sauer has to be 
at least 74 years old. I.e., C&R.

The Sauer 38H pistol probably qualifies as a C&R firearm under current BATFE
regulations.
Depending upon the state in which the firearm is located, one need not sell
the firearm through a licensed dealer, to a resident of that same state.
There is no Federal restriction on the transfer of a firearm between two

To sell a handgun outside one's state of residence, the firearm must be
shipped to a licensed dealer in the purchaser's state, it is then that FFL's
responsibility to ensure compliance with applicable state and/or local
ordinances and regulations.
Whether or not a firearm is on the C&R list, the transfer if not within the
state of residence of both parties, must be in accord of the GCA 1968 as

That's true about the 50 years since manufacture requirement to be a Curio and Relic firearm.  Unfortunately that does not help anyone who does not hold the "01" Dealer FFL or the "03" C&R Collector FFL that allows him to sell and purchase C&R firearms for collecting purposes.  That license is easy to get, but it does require the approval of the applicant's chief law enforcement officer (usually the county sheriff) and a modest fee.  There are also bound book acquisition and disposition logging requirements.  Thus, the fact a a firearm is a C&R is of absolutely no value to those who do not hold an 01 or 03 FFL.

Every Sauer 38H is a C&R by age alone since 1995.  
  https://www.atf.gov/firearms/curios-relics
But long before any Sauer 38H ever got 50 years old, it was explictly defined in the BATFE's C&R List as a C&R:  
  https://www.atf.gov/file/128116/download

Some confuse a C&R firearm with an Antique Firearm... an entirely different  animal.  By BATFE rules, an Antique Firearm is any firearm made in or before 1898.  Such a firearm is legally NOT a "firearm" under BATFE rules and is thus subject to no federal firearms regulation.  There is no federal control of transfers of Antique Firearms.  Not even a convicted felon is prohibited from possession of Antique Firearms.  All this can make a world of difference to a non-FFL purchaser.  It has no beneficial effect on transfering a Sauer 38H, all made between 1938 and 1945.

I held an 03 FFL for about 20 years, but I let it expire on purpose.

ATF considers it a C&R weapon.

*To be recognized as C&R items, 478.11 specifies that firearms must fall 
within one of the following categories:*

 1.

    /Firearms which were manufactured at least 50 years prior to the
    current date, but not including replicas of such firearms;/

 2.

    /Firearms which are certified by the curator of a municipal, state,
    or federal museum which exhibits firearms to be curios or relics of
    museum interest; and/

 3.

    /Any other firearms which derive a substantial part of their
    monetary value from the fact that they are novel, rare, bizarre, or
    because of their association with some historical figure, period, or
    event./

My brother bought me one of these for Christmas & I've begun playing with it finally.?
I've noticed it seems to have an unexpected (& undocumented) behavior when measuring small capacitance values. If I set it up with a small fixed capacitor of say 20pF, in a few seconds, the displayed value starts drifting downward & will continue until it reaches 0.00pF.A similar thing happens with small inductors, say 1uH. ?With larger values like 100pf or 5mH, the drift takes longer to become noticeable.

Is this the usual behaviour for this model?

Message-ID: <CBE3F3E3-6E2A-42B9-BFCF-0BF9E97DC05A@gmail.com>

Can someone enlighten me regarding the SCR-59 and SCR-68 airborne sets from World War I? One online source indicates SCR-59 comprises receiver type BC-12 and is the ?receiving unit of SCR-68?. Looking at the SCR-68 however, it is clearly a receiver and transmitter in one box whereas the SCR-59 / BC-12 appears to be a stand-alone receiver. I am familiar with the SCR and BC nomenclature system since I have plenty of World War II equipment but this one has me slightly puzzled. 

Also, does anyone know of a source for a pair of WE-205 / VT-2 tubes?

Thanks for the help and best wishes to all for 2020.

Someone with an original GRC-9 bias batt, will you please measure it and give me the dimensions?
The 3-cell holder I bought is a cylinder 2.5 x 1.5 cm.  ( Even if you're not used to metrics, you can see that's small )
( Seems to me, a recent conclusion, that metrics work better for small measurements. )
I am sending a sample to the lead scientist on the GRC-9 project, Richard Brunner, for beta testing.

The CW Classic Exchange will take place Sunday Jan 12 1400Z to Jan 13 0800Z and Tuesday Jan 14 1400Z to Jan 15 0800Z.

The CX is a no-pressure contest celebrating the older commercial and Home Brew equipment that was the pride and joy of ham shacks many decades ago. The object is to encourage restoration, operation and enjoyment of this older Classic equipment.

You need not operate a Classic rig to participate in the CX.  You may use any rig in the contest although new gear is a distinct scoring disadvantage as your multipliers are directly related to the age of the equipment you use!  However, you can still work the "great ones" with modern equipment.
There are two (2) entry categories per mode: ?Three or fewer receiver-transmitter pairs ?Four or more receiver-transmitter pairs.

Suggested frequencies:         160M   80M   40M    20M      15M      10M       6M            2M
1810   3545   7045 14045  21045   28045  50095  144100 Khz
+/- QRM. Listen up and down at least 5-10 Khz for crystal controlled stations.

See http://classicexchange.org/winter2020/Winter_2020_CX_Rules.pdf for complete details including scoring, categories, bonuses, and log submissions.

As I understand it, the main failure mode is the separation of the tiny leads from the crystal surface.
Otherwise, for a cleaning try, what immediately came to mind is a small ultrasonic cleaner, like for cleaning jewelry.

That is correct: I have TONS of the little beggars and fully 50% are no good. 
Opening those which are bad reveals exactly what you mention above: the 
tiny leads are separated from the crystal, and I have not yet found a way to 
reattach them.

Did some googling until I found some papers relating to the manufacture of FT-241s. The papers all say the leads are soldered to the plating on the crystal using an aluminum iron tip or hot air. ?The aluminum was important because it wouldn't draw solder off the joint when withdrawn. I thought this might be useful info as I think I've seen it assumed they were welded.

Message-ID: <5f9e4345-1d45-9857-eedf-6e3c94e10955@comcast.net>

Another option:? There is available a small LED which works very well on 
1.5 volts, identified as "222 E10 base 1.5-3 volt LED." It's a screw 
base.? It starts giving light at 0.5 volt, good output at 1.0 volt, 
plenty more at 1.5 volts, and runs very well on the 1.5 volt filament 
line.? Leave the original lamp socket in place, but remove the bulb so 
it doesn't shadow the dial.? Run the leads through the hole in the 
chassis that the original lamp lead runs through, and solder to the 
filament line.? Position the lamp to illuminate the three bands on the 
dial, and hold as you wish. Mine is merely held with tape, and seems 
satisfactory.

There are some miniature electronics in the base, and wrapping an 
antenna lead around the lamp I heard very weak harmonics every 18 Kc, 
but installed in the receiver nothing is heard.

First of all I would not use an ultrasonic cleaner on them as it would
likely lead to greater lead separation.

Has anyone tried a tiny drop of conductive glue?  They used to sell stuff
like that under the description of "liquid solder."  If the contact
surfaces are not too badly oxidized it might work.  The ESR of the
connection is not important because a high impedance crystal cut was used
in the FT-241 rocks.

In this modern ham world, folks that knew, and actually did it, are dead, and if you research, you will find articles in the mid 30's in QST, and in the Handbook of that pre-WW II era that told you how to make your own radio crystals.  Projects included the building of a saw to cut the quartz, how and at what angle, even for overtone units, a start thickness to get you somewhere near your freq. of interest and grinding techniques to bring it to freq.   Brazilian quartz is still available on Epay, not too expensive, and the design for the saw is still doable if you wanted to try making your own.

I will add this, tho it might not be to some people's taste. On a bayonet base socket I had, from some disassembled equipment, I slightly bent one of the "holding flanges" or "ears" at the top of the socket.
I very slightly bent it inward to try to engage the threads of the screw base bulb. I was able to force - fit a screw base bulb into this socket and it held; yes it actually held. With the LED you will practically 
never need to change the bulb, so I think this is practical; you don't have to concern yourself with how easy or hard it is to replace the bulb. HOWEVER I have not executed this inside the GRC-9 where there
is very little room to work !

A seller of such bulb is 
https://www.ebay.com/itm/223625154188
If you need to search Ebay for such item, search on:   E10 LED 1.5 volt 
The screw base is the negative contact, which is good for us.
If you want to look up sockets, you look for " E10 socket ". Ebay has them for no money in wire leads style. I am wondering at this point, maybe we could solder a stiff wire to the base of the bulb and use this
both as ground wire and to hold bulb in place. 
Thanks to Richard Brunner for his many experiments to prove out these ideas.
-Hue 

>Subject: Dial Light for GRC-9 Receiver

Another option:? There is available a small LED which works very well on
1.5 volts, identified as "222 E10 base 1.5-3 volt LED." It's a screw base.? It starts giving light at 0.5 volt, good output at 1.0 volt, plenty more at 1.5 volts, and runs very well on the 1.5 volt filament line.? Leave the original lamp socket in place, but remove the bulb so it doesn't shadow the dial.? Run the leads through the hole in the chassis that the original lamp lead runs through, and solder to the filament line.? Position the lamp to illuminate the three bands on the dial, and hold as you wish. Mine is merely held with tape, and seems satisfactory.

There are some miniature electronics in the base, and wrapping an antenna lead around the lamp I heard very weak harmonics every 18 Kc, but installed in the receiver nothing is heard.

Thanks, gents, for some interesting posts !
I have a couple real early crystals, look like homemade ham things, that I hid from myself. I need to find those and give them to the AWA types who are running old breadboard type transmitters on the air.
On the general topic of 'crystals', I have an interest in growing crystals for piezoelectric earphone elements. A future project.

Hi

Ok so you *need* natural quartz to grow synthetic quartz. The further your seed gets from natural, the
more the result degrades. That does not translate to an enormous demand, but there is a point you can?t 
go past. 

Indeed the USSR also had a ?stockpile? mentality. In their case the quartz stockpile was measured in 
mountains rather than trivial units like tons. They had mines running full time piling up ?reserves? for many
decades. 

The fiber optic industry is by far a bigger user of quartz (fused quartz, but the same chemical compound) 
than the crystal industry ever was. Even with their explosive growth over the last three decades, they are
having a hard time working through the various piles lying around the ex-USSR.

Gents:

     All this print about quartz crystals reminded me of the 1981 IEEE article on the subject:  https://ieee-uffc.org/about-us/history/uffc-s-history/a-history-of-the-quartz-crystal-industry-in-the-usa/ .  I've read it a couple of times over the years.  It's a fascinating account of a program that, in my eyes, was almost as important as the Manhattan Project at the time.  Lots of mom-and-pop crystal manufacturers made - and lost - fortunes in the 1930s in this market.  The paper also mentions manufacturers' names that are familiar to us gray-beards:  Miller, Peterson, Bliley, and Galvin.

I would say series. I don?t see much in the way of reactive components in parallel to the crystal (other than some filtering for the transistor).

How can you tell if this oscillator is designed
for series- or parallel- resonant crystals?

I believe this is a Colpitts oscillator, though it's drawn for maximum
obscurity.  These use the parallel resonance of the crystal.  C407/C408 are
the impedance-splitting capacitors in the feedback path.

Thanks!

Shoulda mentioned that this is the common-collector (or emitter follower)
form of the bipolar transistor Colpitts..  You can also build common-base
and common-emitter forms, the latter probably looking a bit more familiar.
All three forms can be found in the vacuum tube literature and in our
favorite boatanchors, as well.

Dave,

It is parallel.

The giveaway is the freq adjustment cap in series with the rock.  It's
function is to reduce the inductance of the crystal.  A circuit that
operates the crystal in its inductive range is parallel.

Thank you to everyone for your insights into this question.
I think I'm going to try Quartzlabs for a few crystals.
The Canadian Marconi manual does not give any specifications for
the crystals (at least, not my abbreviated copy).

Good Afternoon All,

        I picked up a Conar Model 251 Solid State Oscilloscope. It needs
some TLC, was able to find a Assembly / Users manual. But it dose not
have a schematic. Web searches so far have not turn up any thing. Anyone
have a copy or a source that I could get one from.  Any and All Help Will
be Greatly Appreciated. Thanks.

Somebody here have previously - employed  "3 circuit microphone jack"  ( tip, ring, sleeve ) they feel like putting in a small padded envelope
and I send you about $7 - 8  ?  Yes, this is not a money - maker for you, it's more like me asking a favor.

I could buy a new one, and the postage is $7.75 one place I looked at. You'd think with all the equipment I've scrapped out, I'd have one around,
but no go. This is to replace the microphone jack in a USAAF BC-366 aircraft crew switchbox. Someone  robbed out the MIC jack.

A couple of the wide ? awake readers noted that the jack  I need has to fit the PJ-068, is not the ? inch size plug.
Thanks ? I would have been very chagrined if I had ordered a new 3-conductor ? inch plug.

Pure speculation on my part but looking at it would speculate that was a HF AM Marine base station from back in the days before all marine traffic migrated to VHF FM. Cannot tell from the second photo if there is a receiver under the 813 deck so maybe it is a transmitter only? Perhaps it was used in the great lakes or for river traffic? Think the telephone dial is for remote channel change or remote monitoring. Junked a Gates BC-5 AM Broadcast transmitter some years ago that was installed in 1948 and it used a telephone dial along with a telephone stepper relay for the remote control function, it was remoted over two dry pair telephone lines with one controlling the stepper relay and the second providing the meter output to the remote end. In order to read different things on the transmitter like plate current and voltage you dialed a digit from one to nine and the stepper connected the proper circuit to the remote meter. There was a second dial on the remote at the transmitter end that you used for calibrating the remote control.
It was odd to see a transmitter set up for remote operation back at that time being most of the old time AM broadcast stations had the transmitter located right at the studio being until the late seventies you had to do meter readings every three hours and have a licensed engineer on duty the entire time you were on the air. Or at least someone with a first commercial, now you can have transmitters remoted with no monitoring and use remotes that if anything goes wrong calls you.

Message-ID: <MWHPR22MB026949A208A9DEAE7C18D79EE4360@MWHPR22MB0269.namprd22.prod.outlook.com>

Here are some reproduction Wehrmacht WWII radio accessories I recently bought from Europe. I had to resort to reproduction items to complete some sets,
as these accessories are practically "unobtanium". They are very well made; in fact, they bear the German "Waffenamt" war ministry acceptance stamp.
However, on very close inspection a "kenner"  even disregarding the new condition, can detect they are "repro". But you do what you have to do to get the
pieces and you are thankful this avenue exists. The prices are very retail and if you cannot afford the original, in this case, you cannot afford the repro.

Shown: back rest for manpack radio Fu.Sprech;  2 antenna base for Torn.Fu.b radio; 5-way top hat connector for Torn.Fu.b radio, leather corner hooks for
manpack radio carry straps.

The Annual Richmond VA Frostfest event will be coming up on the first of the month. Just looked at their web page  http://frostfest.com/wp/  and see that there are only six flee market tables that are available and all the others are sold in advance. Just a quick count of the tables show around 250 or so tables at the event, it did sell out in advance last year.
I have table BG-010 and intend to bring a bunch of junk to sell, wire, cables and parts mostly and I have always done well selling at that event in the past.

I came across this interesting site of equipment by the same sell on that

What's most interesting is the junction boxes with all of the cables. Not
mine, or any attachment to it, but thought I'd bring it to y'alls attention
if you haven't seen them.

I wish I had the time, the knowledge,  and particularly the space for a

The militaria firm "What Price Glory" has these 'empty shell' BC-611 repros for $75. Pretty clean job and the size is realistic, unlike the plastics body BC-611 CB toy offered by "Ultimate Soldier".

Question: does this have potential as a drilled case for tuning up your real BC-611 ?

Message-ID: <MWHPR22MB02692353CFEBDBE59790F4ADE4300@MWHPR22MB0269.namprd22.prod.outlook.com>

Looking at the December 2019 issue of the 'Surplus Radio Bulletin' ( I assume this means military surplus radios and not surplus radio bulletins ) of the  'Surplus Radio Society',
Netherlands, and going by some Dutch words approximately similar to Deutsch, i read about a "test carried out over some distance" using a BC-611 on  40 meters. Apparently
the BC-611 was set up with different crystals for receive and transmit freqs, 7073 kHz transmit and 7070 receive, using BC-659 crystals. No further details. I would think with
the antenna quite a bit more efficient here than on 3885, range would be substantially better ?  But here, "the" frequency for low power AM operations is 3885. I prefer to
leave mine working in the original frequency range.

And this is that rare occasion where the consensus is actually correct.  See SHIPS 242A.  GF-11/RU-16 was bought for USMC.  At least some of them went into the M2 Halftrack  configured as the M2 Tank Destroyer (Gun Motor Carriage 75MM) when USA gave them to USMC after they were replaced by the M18 TD.  Several years ago, I supplied and helped install one in what is thought to be the sole surviving example.

It would be nice to have a worldwide frequency for low power and 3885 is 
widely used in North America but it is outside the region 1 bandplan. 
Maybe some year.

If you are familiar with the RME CME-50063/DB20, preselector/amplifier, wonder if you noticed some irregularities in the schematic and alignment procedures?  There are 9 trimmers in it, 3 you set at 1MC that are used on all bands and are across the main tune cap., the rest across the bands up to 30MC.   On Band 4, the 7MC adjustment uses a trimmer that is selected first on Band 3 which is not mentioned as part of Band 3 alignment.  Band 3 setting was lumped into the settings of the main tuning cap trimmers at 1MC.  I noticed peaking band 3 at 5MC with cap CG worked better than peaking it on Band 4  at 7MC with the same gain results on both bands.  Bands 5 and 6 peaked fine on the remaining trimmers as instructed except for the last adjustment for 30MC which was also one of the caps, CD,  set at 1MC, and had little effect.  I have the original instructions for the DB20 from RME, but maybe there was a correction?  Also, found it odd that the schematic drawn with the band switch in Band 6 where conventionally it would be at Band 1.

I have uncovered a control head for a
Stoddart Aircraft Radio MRT-5A.

This is just the cockpit control head,
remote tuner, mic and headphone jacks
volume and ICS/Transmit switches, no electronics.

What I think is the voice/range filter
is a part of this head as well.

Very tired looking, but inside looks
nice.

Anyone want it, just for postage.

I have two shockmounts taking up space that
someone can have for postage.

MT-362A/A  I think this is for some type of
            IFF gear. APX something or another.
            Some flaking paint, but otherwise good shape.

MT-608/APR-9. Mount is labeled as holding the
               tuning units for the APR-9.
               Dusty but in good shape.

Any takers?

Just trying to reclaim space.

That is very interesting. I didn't know there were any in the continental USA. I wonder what the power of this station was. 

There was an Army training base out here in western Oregon, ?Camp Adair, which at its peak had a population of tens of thousands; I think it was actually Oregon's "second largest city", but even with that size, I 

have not found any evidence there was any kind of broadcast station there. ( But it started at only about 7 miles outside of Corvallis, Oregon, which did have radio stations. )

 ?

Many years ago, I walked the halls of an Army hospital at Ft. Lawton, WA, with a transistor radio trying to find out where station "KURE" was. These were the one-story long, wooden buildings with numerous rooms off the 

walk-through hallway, almost a kind of "shotgun shack" construction, and these buildings were all linked together, so you could walk for a long time. Some of you will remember that style construction. What I eventually

concluded was that "KURE" was a "wired broadcast" operation. I was a youngster, and didn't know much. I also recall out at a very small town on the Olympic Peninsula, trying to figure out where "LaPush Radio" was 

located. I finally figured out that actually ?meant "LaPush Radio Repair". 

 ?

Camp Adair is now gone except for just a few buildings and a natural wetlands park. 

Fort Lewis, right in Seattle, became a park. Still has a large radar installation, Army cemetery, and a couple buildings.

Does anyone have any information of AFN (Armed Forces Network) operations Stateside during WWII. There is plenty of info available for overseas ops in Europe and N. Africa? but information on? US station operation is scarce. Evidently there was a station in operation at Ft. Dix under the call sign WDIX.

Good Morning,
Back in the day I had gotten one of these receivers bymail order from a west coast surplus dealer. I traced outthe circuit and thought some details strange. This hasbeen bugging me for years.
Recently I found a copy of the manual, which gave anexplanation for the design. If anyone else is puzzled bythis odd duck, I scanned the manual and would be happyto send a copy.

I'm looking for a CW-62017 Junction Box for the
RU-19 receiver. Although I could use the CW-62007A
junction box for the RU-18 as a substitute.
(I would have to hide the dropping resistors for
the filaments and relay in the external wiring).

The RU-16 and RU-17 junction boxes are not usable
for what I have in mind.

Not looking for a museum piece, just a fair
condition usable unit. I find I prefer my
gear to show a bit of use.

Anyone have an extra laying around?

Thanks

I have an RBM-1 receiver(6-tube)-transmitter(3-tube) unit, which is most likely the model being used as a prop in that movie scene.? It is definitely not an RBM-5 (which was between the RBM and the RBM-1.

My RBM-1 was built in 1950.? It's an interesting unit that reflects its design origins in the late 1930s.  It's not nearly as well-designed in any characteristic as the US contemporary RT-77/GRC-9.

Here are some descriptions and better photos here of the RBM-series as well as other period Soviet radio gear from a mid-1950s UK military publication:

 http://www.radiomanual.info/schemi/Surplus_Handbooks/Foreign_military_signal_equipment_USSR_1955.pdf
 https://www.radiomuseum.org/r/unknown_rbm_1rbm.html

There's no chance of confusing the visual appearance of the MF/HF-A1/A3 RBM-series with the VHF-FM R-105D, nor the later R-105M.

When I looked at the Russian RBM schematic and read about its pre - war development I was quite impressed. From seeing a couple examples of Russ pre-war and WW2 radios
I tended to think of them as rather crude. Wehrmacht equipment is often touted as so wonderful but in the case of this class of field radio, I mean < 5 watts low HF band, I think
the RBM is clearly superior to the German competitor, the Torn.Fu.b series. The Torn. is larger and has an older - style circuit and also looks older. ( "Torn." is short for "Tornister"
= pack. )  
Since that fellow in Norway won't respond to Americans, I had a Czech contact obtain for me some antenna sections and base for the Torn.FuG.k, similar to the above set. The 
antenna has an X - style antenna hat. The antenna base unit is X - rare and people even bid up "dug" examples from Russia to restore.

My work on a B17F project leads me to seek out info not readily available online, so I use aviation museum archives, and look for books that may contain one scrap of esoteric data.  I bought a book from ABE Books on service and instructions for B24D radio equipment.  In it, it tells you how to calibrate or reset a BC375D to it's TU's after replacing the master oscillator tube.  On the D model is a control right above the name plate on the front.  You tune up the rig to CW power on the highest frequency of the highest frequency TU available, 'lock' the key down for 25 to 30 minutes, and then adjust this control to zero beat the transmitter using a freq. meter.  I guess when 
VT4-C's were a dime a dozen, keying your BC375 for 30 minutes at full power was not a concern.

Looks like a neat rig.

Many years ago, I was given a brand-new, never used, TechRad T-350XM transmitter with 
separate speech-amp by MARS..

What a wonderful transmitter!

A pair of 813s modulated by a pair of 805s (as I remember it). Had a wonderful VFO, and it 
covered 1.5 through at least 20 Mhz. Had a built-in wide-range antenna coupler at the top.

When I left Missoula, Montana several years later, I gave it back to the Montana State 
MARS director. He then traded it to someone for a T-368.

I had a photo at one time of an entire room full of those transmitters at some Army base 
somewhere, all neatly lined up side-by-side and ahead and behind, with antenna leads 
going straight up to the ceiling.

Apparently many of  those were sent to England, and there are very few of them left here in 
the U.S. I did see somewhere on the web where someone had restored one and had it on 
the air.

I sure miss that rig. It was wonderful.

The USS Wisconsin Radio Club now has the RAK and RAL receivers.
One of the power supplies is missing its nomenclature plate and the
screws that secure it.??? Photo attached.? If you have one you can spare,
it will help them in their intention to keep the equipment as authentic
looking as possible.

I don't need it in either case, but is the box for ATA (as the Subject says)
or ATC (as the text says)?  And should we assume from the weight given that
it is empty?

I had one of these, Hue. It was the transmitter only, in a smaller cabinet,
with mating supply and cables. Found an original manual online for it.
Ended up trading it to a friend for another rig. He sold or traded it to
someone else.

Very nice, high quality construction. Didn't look like it had seen much, if
any, use. Very little information out there on its use. The one item I
found mentioned use at shore and harbor batteries.

Always saw it as being in a similar category as the Meissner 150B which is
seen in limited numbers, though more often than the TechRad gear.

Todd, so I have my information correct as possible, you are saying that the transmitter ( at least ) was available separately cabineted ?  Very interesting, as the manual does not include that option.
I note that the input power is 500 volts 160 mA under all conditions. 90 watts.
Where did you find a reference to it and its possible use ?
Definitely one of those "rare sets".  I wouldn't be surprised that total production was in two digits.

Check out this thread. Looks like the LRR-5 is similar to the receiver
portion of the R-T set in your photo????

Looks like the same panel size and some of the mechanical design was held. Certainly too expensive to build for war ? expendable use in
vehicles or small vessels.

Check out this thread. Looks like the LRR-5 is similar to the receiver portion of the R-T set in your photo????

The window to the left is the actual frequency indicator, two bands 1500 ? 4300 and 4300 -12000. Right above the tuning knob is a logging scale.
One the right side is a speaker with louvres. The receiver has a 6J5 HFO with VR105 regulator and 6J5 BFO.  Different from TCS.

"NOTE: RECEIVER RADIATION:
The R-50M receiver has been basically designed for low radiation from the high frequency oscillator. To this end, the shielding in the oscillator and RF stages
is extensive. In addition, oscillator injection voltage to the mixer stage has been kept to a minimum consistent with good performance. In many cases,
however, receiver radiation is of no consequence and my be dispensed with in favor of increased sensitivity. Note that R7, ( the oscillator plate voltage drop
resistor ) is normally shorted out at the factory. If reduced radiation is an essential factor, the short should be removed from across this resistor. "
.........

Navy to Tech Rad ( in my imagination ) :
"This manual has no voltage or resistance tables ?!  Not acceptable - send it back to your technical writer for rework !"

Aha, the situation  is becoming more clear.
* Both Navy and Army bought a variant. The Navy manual, maybe equivalent to a prelim, is actually a Tech Rad publication identified only by the contract number NXss-LL-23312.
( Nick, what category of equipment is 23 ? )
* The package transmitter ? receiver is TR-50.
* The solo transmitter is T-50.

Here's a link to some photos of one in WI, looks like it was for sale or ?
on some recycling site.

Some good shots of the interior as well.

The 23xxx is just a contract number rather than a class of equipment.
But LL indicates a Lend-Lease contract which may mean why we don?t see
these here.

Yes. That has been modified in a couple of ways, besides the meter panel at the top. 
Originally, that top panel included a wide-range antenna coupler with an RF ammeter in the 
center-top of that panel.

Also, the bottom panel never had any meters in it originally.

Lastly, it is quite clear that the the panel above the VFO compartment has been replaced 
also. Originally, all were grey.

I see he also has a TV-2 tube tester. I have two of those plus a manual or two for mine.

One of mine works, and one doesn't.

I am not at all sure that the complexity of those is worth it, though.

Thanks for the info, Robert.

I was wrong about the Navy buying this. I misinterpreted the contract number to be a Navy number.
Thanks to Nick for pointing out the Lend Lease designation. I have a list of LL equipment somewhere and I'll have to see if this
set is listed therein.

Hey Jimmy Horn, Seattle area, why not pick up a copy of 'Aviation History'  March 2020 at Fred Meyer's, or just read the article there, and maybe comment on it?
I recall you telling me the AN/ARC-2 was installed in the HSS-1 chopper you flew.
The article of interest is called "The Night Dippers - Helicopter Anti - Submarine Squadron 5 pioneered all weather night operations in the early 1960s..."
( What else did the chopper carry for communications? )
( Couldn't find an email for you, thus the broadcast. )

Message-ID: <CAF6Vb56LXPt67MKPFLj9PrTabi+4m9C2+RdgPii3EeFgkbwmcQ@mail.gmail.com>

I'm curious if anyone is using one of these as their main station
receiver and what they might have done for muting during transmit.

Usually I take the old National approach and break the B+ with a
relay.  In this case I don't know where I could fit one in a very
densely packed chassis.

Any thoughts or experience to share?

Thanks,

For those who use this old workhorse on the IF output of a milsurp receiver, does anybody have an assembly manual for the HO13 panadaptor?  The online manuals do not contain the build instructions.  I need to 'see' how the L2 circuit is wired, I know how it is by schematic, but  think the previous builder may have L2 backwards with the normal hot end of the coil swapped placing the tap and normal ground end on the hot end, and  he jockeyed it to make it work.  This one is a bit of a mystery as it was working fine on 455Kc, but I want it on 1681, easy with this model since L2 is the same for both freqs, just a few resistor changes.  When I wire it as shown in the schematic, Bandwidth acts like a band centering control, and the band centering, 'Pip Center' has very little effect.  So, also have issues with the accuracy of the chart on the schematic that shows wiring for the various IF freqs and the different resistor values they spec.  Gone over my work till I am bugged eyed and can't see where I might have made a mistake.  As found, the varicap diode cathode went right to the hot end of the coil instead of ground, the .001 coupling cap that should have been making that connection, was a .005 going to ground.  Could find no 'errata' sheets or factory notes about it.

I restored a TekRad  350 ten ? years ago and had it on the air for a few
years and then sold it to a ham in Texas.  Unfortunately I do not know who
it was.  This unit came out of the Philadelphia Navy Yard.  I believe that
they were a replacement for the Marconi transmitters that could fit 2 of
them in the back of a military truck - the reason for the non-standard
width.  Quite a workhorse - could run all day without working up a sweat.
I had written up a restoration article for Ray at Electric radio.  He
misplaced the article before it was published and my pc crashed and I could
never recover it.  The buyer called Allied Van Lines to ship it to him.
They showed up in a big rig - wrapped it in blankets like a fridge -
wheeled it on the truck -  all 600 pounds and it arrived in TX without a
scratch!

I may be wrong?? I seem to remember having to short two pins on the back 
connector.

Thanks to all who responded for my request for help.  Gary, K5JWK provided a scan of the L2 assembly area that answered all my questions, and confirmed wiring that was not correct.  I have since put it right, but still wonder about correct operation of controls.  Did discover all the scopes trace control pots were wired backwards, except intensity, and after inverting control positions for BW and centering per the manual, full CCW is really CW,  it aligned much better, but still has issues.  If anybody has a HO13 set to any IF freq except 455Kc., if you rotate the scan bandwidth control, does the base line trace move left or right on the screen, requiring you to use horizontal position and horizontal gain to put it back on screen with the scale on the CRT?  Or if you turn scan BW, does the trace stay aligned with the CRT scale or move just a tiny bit?

AN/SRR-12, -13, -13A receivers have seven connectors on the rear, but no muting circuits.  You may be thinking of the R-105*/ARR-15 with those muting connections on its one rear connector.

I have an AN/SRR-13A from NAVMARCOR MARS that I last used with a transmitter in 1970.  I used an external relay that on transmit grounded the receiver antenna input connection and switched the antenna to the transmitter...not perfect but better than making internal mods to the receiver.  For more than five years I carted it and an HW-101 in my Opel Manta duty station to duty station from California to Maine and several points in between.  I doubt it would have survived the typical military household goods shipment.

The SRR13 standby/operate switch supplies B plus to V501, the first RF amplifier/preamplifier.  The radio has a fast acting current relay to protect the RF input from strong transmitter signals.
To "mute" the receiver, simply add two wires to the standby/operate switch, bring them to rear connector shelf, and either add a proper connector, or remove an IF or PAN connector and install your two pin connector there.  Place the operate/standby switch in standby, and using a relay, close the circuit brought to the rear panel for operate, a simple mod.
OR, just use the operate/standby switch when transmitting.
Switching the entire B plus line will cause stability problems.

I see he's at least dropped the price some. Originally he started it at
$4,000 or $7,000.

He's right about one thing - it truly is in unbelievable condition.....

 Yes, I know what an RAX is.
But what's puzzlin' me, is why these "extra slots" ? Too strange.
I commented before to Brian Harrison that a lot of Japanese radios have similar semicircular "slots" in their tuning dials, and I cannot divine the purpose
for this, except in that case, some kind of logging, like you mark thru the slot with pencil ??
Oh well.
Funny, isn't it, these people who ask $x000 for their treasure?  It takes a while for it to sink in, that the appreciative eager masses out there are NOT going
to buy. Maybe there's even a law here, the higher the asking price, the longer it takes to sink in, no one's ever going to bite. -Hue

Subject: [Milsurplus] Japan 94-2 Transmitter on Ebay
Message-ID: <MWHPR22MB026951E7237025053781DC1FE4050@MWHPR22MB0269.namprd22.prod.outlook.com>

Here's a transmitter from the Japanese 94-2 Ground - Air set. Both Brian and I have owned the receiver for this set.
I am a little surprised to see this transmitter offered again, and then, maybe not.
Note, seller does not specify weight anywhere in listing. Note also the mansize carry handles.
I was offered this item long ago, had to be somewhere in the decade 1985 - 1995. Of course, there's no way I want
to own something that takes two men and a boy to lift. The price at that time was less than 1/10th the present price.
I have to say this is sad, but..."Good luck with that !" Due to size it probably belongs back in a museum of some sort,
but with its condition, it hardly is something that visitors would appreciate. Needs a fair degree of work to look
respectable again.
I have a photo of this type equipment being used in the Aleutians.
Note also the plug-ins for the indicating meters. I do not understand the why of that construction. Did they burn out
a lot of meters, or maybe it was to be able to remove the delicate meters when moving?

When the band switch is rotated, the extra slots rotate along with it to the top of the dial to reveal the desired band while simultaneously covering up the undesired bands.  Like Mike says, the main cover is missing.  If it were in place, you wouldn't see the extra slots.

OH okay ? the WHOLE circular disk moves ! I saw this disk as the front of a whole new cover, imagining a frequencies disk
behind it.
Like one of those optical illusion things, depends how you look at it.
thanks-
Hue ( but still not sold on this item. )

Does anyone on these two lists happen to know Mark Mears of Harrison, OH?
Several weeks ago he bought a new leather handle for the BC-659 etc. from me
on eBay.  I shipped it and in three or four days the USPS say that they
tried to deliver it but couldn't (doesn't say why).  They say that they left
a notice and that it is at the addressees Post Office available for pick up.
According to their web site, he never has.  I sent him two messages through
eBay and one direct with no response.

 

It wouldn't be the first time that USPS actually delivered something and
failed to scan and mark it as delivered.  But as he didn't respond to either
the eBay or the direct messages, I thought that I had better check.

Message-ID: <MWHPR22MB0269EBAA9FAF623E4FDD2C7FE4070@MWHPR22MB0269.namprd22.prod.outlook.com>

I started looking online for a G4M 'Betty' bomber model and one thing led to another.
I found this photo of a radio from a Betty wreck on Yap Island:

[cid:image001.png at 01D5D78F.D6E3DBD0]    https://www.aviationarchaeology.com/src/Yap/site4betty.htm
The provenance shows signs of earlier human intervention. Perhaps some native wanted the cables for a belt, or to help construct a hut, or a weapon.

I thought it looked familiar. I then saw this on the Yokohama Military Radio Museum site:

[A picture containing electronics  Description automatically generated]      http://yokohamaradiomuseum.com/tenjitop.html

I have a Navy O.N.I. ( Office of Naval Intelligence ) list of Japanese aircraft with radio type carried. However, I find this list next to useless.
There seems to be no hard and fast rules. This radio is listed for the 'Dinah' observation plane, but not the 'Betty'. Additionally, I have seen a
bringback VHF radio from a crashed Betty, with a photo of the crashlanded plane in a Philippine rice paddy, and this was the ONLY radio onboard.
So the radio may have been keyed to the mission, that is, whether long distance or not? As well as availability, and we know the Japanese were
poorly supplied for spare equipment.

I recalled then, I do have this radio, stored elsewhere far from here. It was taken from a base in Japan. Unfortunately, I do not have the crystal
calibrator/ RF output indicator, or the control box. In Allied nomenclature, I think this radio is called 'Type 103'.  The "103" means 1943. This is
a HF  5 - 10 MHz AM, CW radio of about 75 watts input. Allied publications called it one of Japan's best, most modern radios. As you can see,
it departs from usual Japanese design, in that is designed for remote, not local control.

Ah, now back to what I really should be paying attention to: taxes and medical bills.
