Message-ID: <CAFcNxxX8gMn2EHWe=6iaHH2U-C2oApv1VbrWiTSOardgjJk+rQ@mail.gmail.com>

Just signed with KA5IXE in LA running TCS, on 40m with my TRC-77.

Turned the radio on just as he was signing with another station on one of
my crystal frequencies.

Cool to run into stations running mil gear outside of nets.

IF the set covered 40 without alignment trick i would be in love with 
it, but 80 band just does not interest me. So that means my interest in? 
WW2 "combat tactical" equipment, that is, <6 MHz, has ebbed in favor of 
skywave equipment.

I found it would double in the final to 40 meters without any trouble, 
and made contacts, though I don't remember how much power out.? 5-7 
watts rings a bell.? Mine tuned the bottom of the 40 CW band- I don't 
remember if I "fudged" the Osc. or not.

Have you seen the "complete, NOS" 474 with accessories on Ebay for 
$3000?? The more those of us near or in retirement watch our money decay 
away, the more desperate they seem to be to get silly money for their toys,
the market for which collapsed years ago.? Kinda sad.

If you ever want to sell or trade for those 474 canvas pieces,
I'm certainly interested.
All the best,
Dave AB5S

Due to a last minute venue problem, the MRC Friendly Fest scheduled for
this Saturday, November 2, 2024 is off. It's too bad, because it usually
has a good turnout and some interesting items.

https://wi9mrc.org/mrc-91-friendly-fest-2024/

(I don't know why this posting is dated August 25th; it was more likely
October 25th. I reserved tables on October 15th and received a confirmation
the same day so it was still on two weeks ago.)

Dave, that cable Hue shows is very small, 8 inches or so. It seems odd to have a TCS remote box so close to the dyno?

Hi all,

I'm doing a presentation on military radios throughout the various US conflicts. I have several WW2 radios to bring, but the BC-1000 is so iconic and important that I thought it would be great to show it. But I don't own one! Anyone in the NY/NJ/CT area have one I could borrow? Condition is unimportant (both physical and operational). Just looking for an example to show. Presentation in November 10th. I'd be happy to pick up and return in person.

thanks

Hi all,

Question about the evolution of these aircraft radios. I know the BC-375 was a 1930's design. The ART-13 was a major improvement but still, like the BC-375, required the use of a separate receiver. And then you have the ARC-2 which is a transceiver in a (relatively) small package. Was the ARC-2 introduced after the ART-13/ARC-8? One might think that given the combining of functions. Anyone know the approximate years of service for these radio systems? And what aircraft they were used in?

thanks

The ARC-2 is a very strange beast with its varying IF. It was clearly thought of as a voice radio first, maybe as replacement for Command Sets. It's kind of a hassle to use on CW - there's no "BFO offset".

Is there an online database which will give me information on an "order number" or contract number on the data plate of a radio? For example I'm looking at an AR-88 with contract number "NObr-39228" but I'm interested in doing this for many of my milsurplus radios.  Is there a good source for this?

Unfortunately I haven?t ever come across such a database for Navy contract
dates.

The NAVSHIPS 94200 Directory of Communications Equipment often gives
contract number and date but not always. No luck on the AR-88 entry.

I suspect that cable was designed to go between the dynamotor and the
interphone amp, CMX-50128A.

Isn't the ARC-2 perhaps the first Collins transceiver?? Also the first to have a hermetically sealed HFO later known as a PTO.? The ARR-15, an offshoot of the ARC-2, with it's RF slug racks, IF slug racks, two PTOs seems to me to be the start of the 51J except that the ARR-15 is single conversion? The 75A came later, AFAIK.Jim

A tip for those brave enough to tackle an ARC-2: be very careful with the heat of your soldering iron on those little coaxial cables. The internal insulation melts if you just look at it hard, and they didn't leave a lot of slack.

Yes. You are correct: it is difficult to use on CW.?And the selectivity is much too wide, even for me. I prefer to use the 50 Hz filter between my ears. I kinda like to keep track of other nearby signals.But the ARC-2 is a bit too broad even for me.And IMHO it is really much too big for what it is.But it IS a very interesting rig.As I remember it, Dave suggested an easily removed mod to increase selectivity in it.I own an almost NIB one here.If I live long enough, I'll get it on the air yet.Ken W7EKBSent via the Samsung Galaxy S21 5G, an AT&T 5G smartphone

The ARC-2 is a very strange beast with its varying IF. It was clearly thought of as a voice radio first, maybe as replacement for Command Sets. It's kind of a hassle to use on CW - there's no "BFO offset".

I have 2 of them. I do not know if i will keep any! I like the looks and the good frequency calibration.
Years ago, in Seattle, a burglar took an ARC-2. I still don't get that and wonder how it ended up. This would be around 1985, and was one of the ones sold by Fair for $50. It occurs to me now, this may be one of those surplus items whose value is "flat". I also about the same talked with a guy who had used one in his car on a camping trip. Yes, believe it or not. I don't recall how he got the 24 volts, and yes, he said when receiving CW you had to retune off the operating freq, and yes he said you could do it, which sounded kind of not so practical. Made me think of the Forest Service model S radio, a vhf superregen with no rec - trans equaization, so that a QSO gradually crawled across the band.
Roy Paffenberg's selectivity solution in his conversion booklet, using a regenerative IF stage, is not for me, as i tried it with Command Receiver and i was not at all happy with its functioning - as we discussed here, some time back. I have an early SSB era book that shows a Franklin osc using 2 6C4 with 2 caps of 1 pF attached to the LC. A 2 terminal oscillator. 'Amateur Radio Techniques' by Pat Hawker ( RSGB book ) has a 2 terminal regen amp, no LC of its own, which you connect across an IF can LC. So i was thinking this SSB book circuit with approx 1 pF load could do the same and not create major tracking problems. I think you build likecin the Hawker book the works right into the radio and the DC control pot is elsewhere you choose. I do not like the external Q5er idea, the external MF receiver; that's too Mickeymouse for my taste. Who knows if i wii actually try this though. I need to radically decrease the number of projects. Oh, last note, i would not use 6C4 or any other tube. I would use 2 MOSFETS.

The SCR-288 set now on Ebay is mine. I let my brother sell off much of my stuff as i downsize, as he has a very minimal income.
I do not much manage his work. I think this listing is not well done at all and i will give him some suggestions, but it?s up to him.
What and how he does, does not affect my own Ebay reputation, which is important to me. My preference, and the way i usually
do auctions, is just list it for the minimum i would take and let the auction process proceed. Usually. We did learn a good lesson
earlier on. He had 2 of German ?FuSprech A? armored car and SP gun radios, a cute little 24 MHz AM voice transceiver. He sold
them both for about $1900 each to Ebay bidder ?Messerschmidt?, which we thought was doing okay. One week later Ebay seller
?Messerschmidt? sold on his own militaria website store, one of these 2 for twice what he bought it for, and kept the other, which
made the one he kept, essentially cost-free for him. We did learn from that, believe me ! So if you have the time, are not desperate
or in a hurry, and your auction item is not common at all, maybe even accurately described using the overused term ?rare?, you
might want to do a ?reverse auction?, where the seller gradually lowers the price until it sells. In such case, the 7 or 10 day auction
window may just not be enough or the auction format may not necessarily work to your advantage. An example would be the
BC-1209 ( SCR-583 ) he recently sold. One of 2 i know of. The buyer, from what i heard of the sale, is, well, not very savy about
radios or their values, but his money was green, and so be it. Buyer also got 1 of 3 manuals i know of. Years ago, around 1980, i
gave one copy of the manual i received with this G&G purchase, to Tony Grogan, and who knows where this manual went, when he
passed away. I ?believe? i still have one SCR-583 manual, but if not, so be it, also; i just couldn?t get it together enough to scan in
the manual i mailed away.

Hi

Over the years, I?ve run into folks at hamfests who would supply you with repo tags for pretty much 
any mil item that Collins ever made. All of them offered custom serial numbers. Some stamped serial 
numbers right there when you bought it. Others shipped the tag to you after putting the serial number 
on it ?back at the factory?. 

At least the ones I ran into did an amazing job on the tags themselves. Typically the weak point was
how well they duplicated the serial numbers (font / size / ?.).

Ok, so here is a question for all the smart people out there: From the first contract on 12/41 (NOS-LL-95008) for the TCS-2 to the last production run in 7/45 (N5SR-10539) for the TCS-15 How many TCS sets were produced?
Appears to be a simple question but cannot see any answer, considering the numbers that I have seen and that it was used in almost every surface vessel in the US Navy for decades I will speculate that it's no less than ten thousand and may be higher.
They were produced by Collins, Stewart-Warner, Hazeltine Electronics and Air King and for just a four year production run may be one of the radio platforms that the government got their money's worth and then some.

Speculation and opinion beyond this point, if easily offended do not read!
Always amazed by radios that served well beyond their service life. The TCS sets were in service well into the sixties and some survived beyond that and were only driven out of use by the advent of SSB and VHF FM radios, in addition to this they were one of the many radios that were used and favored by Hams. Other radios that were just as successful like the BC-348 and ART-13 were also in service long after WW2 and prized by Hams. Other high production lines like the ARC-3 and the ARC-27 served for decades but never had the Ham popularity. High production numbers often are indicative of a successful product line but not always. Consider things like the command sets that were way popular (at one time) with Hams but were basically useless by military standards at the end of WW2 Think of the huge quantity of command sets that were produced during WW2, maybe over twenty thousand? Verses the in service life of those sets compared to something like the TCS assuming value is a function of cost compared to length of service.

I did find this on the collins website

https://collinsradio.org/cca-collins-historical-archives/the-equipment-of-collins-radio/the-war-years/

Interestingly, it seems to indicate that for the TCS, about 35,000 were made (it says "all manuf.") and the ART-13 had 90,000 produced! Wow. I would have expected the TCS to have more produced than the ART-13 since the TCS were used is so many more roles. Or could it be that the 35,000 was only for the models 5,7,12 and the other 12 versions increased that number substantially?

Subject: Re: [MRCA] TCS production numbers

I don't know total numbers for TCS sets.  The Collins production is available on the CCA website.  I assume would assume the total is over twice the Collins production.  As for command sets, given the numbers of aircraft produced over the period of 1940-1945, and assuming the vast over production of sets, I would say closer to 100K.  It is interesting that in 1955, Collins introduced the URC-9, which was an updated TCS in essence (More power, bigger frequency range, modern design, similar form).  I don't think it was actually produced in any more than prototype numbers.  It might just be the coolest AM/CW rig ever!

Interestingly, it seems to indicate that for the TCS, about 35,000 were made (it says ?all manuf.?) and the ART-13 had 90,000 produced! Wow. I would have expected the TCS to have more produced than the ART-13 since the TCS were used is so many more roles. Or could it be that the 35,000 was only for the models 5,7,12 and the other 12 versions increased that number substantially?

I don?t know total numbers for TCS sets.? The Collins production is available on the CCA website.? I assume would assume the total is over twice the Collins production.? As for command sets, given the numbers of aircraft produced over the period of 1940-1945, and assuming the vast over production of sets, I would say closer to 100K.? It is interesting that in 1955, Collins introduced the URC-9, which was an updated TCS in essence (More power, bigger frequency range, modern design, similar form).? I don?t think it was actually produced in any more than prototype numbers.? It might just be the coolest AM/CW rig ever!

Ok, so here is a question for all the smart people out there: From the first contract on 12/41 (NOS-LL-95008) for the TCS-2 to the last production run in 7/45 (N5SR-10539) for the TCS-15 How many TCS sets were produced?
 
Appears to be a simple question but cannot see any answer, considering the numbers that I have seen and that it was used in almost every surface vessel in the US Navy for decades I will speculate that it?s no less than ten thousand and may be higher.
 
They were produced by Collins, Stewart-Warner, Hazeltine Electronics and Air King and for just a four year production run may be one of the radio platforms that the government got their money?s worth and then some.

It's not a "Cannon" style connector, Dave.? It's a 19 pin AN3106A-22-14S 
Amphenol connector, according to the ARC-39 manual. I may have 
one...will look later this morning.

I have a data plate that is
warping/shrinking up that if possible without damaging it I would like to
flatten out. It looks to be fibrous and not plastic.
I'm sure this question has come up before. Unless someone has successfully
found a way to do this...I'm maybe leaning more to just leave it as is.
It's from a Navy AMA radio that was going to be used in a amphibious glider
but the program was scrapped. It's similar to the BC-721 that were used in
the gliders on D-Day.

Due to a number of last minute conflicts, other lame excuses like having to work that weekend and a plethora of other problems like my toe nails is coming off due to dropping a bowl on it last weekend I am regretting to announce that the field component of Able Archer 83 at camp X-Ray will be canceled. The on air event is still going on, and I will attempt to operate on the 7087 RATT Net and the 7296 USB Net Saturday morning but not be in the field. I will still be using the W3A call for those operations.

I had some large circular dial plates that sound like they were the same material. I could flatten them after hot water soaking but they always curled back up before long, no matter how long I kept them under weights to flatten them.

I have seen  some Navy equipment with apparently plastics blue nameplates with cracks at the corners where the fastening screws are. 
There is no solution for this, i suppose. Maybe, occurs to me, remove some of the screws that apply horizontal limits to shrinkage, "process" 
the screws so that they have no shank, and something like glue to hold the screw head and nameplate down. Or have a good replica made.
Or, none of the above. 

I have a Japanese portable, from WW2, where all the control legends are on semicircle white material, which i suppose is a form of plastic

What about ironing them, or similar?

Hot water, lay a sheet of aluminum over them, then run an iron over that 
to "re-set" them?

I've seen plenty with the issue, but never played with reversing the 
process.

Anyone else here part if the "SCARS" forum, Southern California Antique 
Radio Society?

I bet more than a few there have had to deal with the issue.

Ironing might work but when you've only one example to play with, you tend to be less adventurous with possible corrections. One problem, as I see it, is we don't really know what the material is, precisely, so we have less knowledge about how it will react to lots of heat, etc. Unless we have sacrificial copies to experiment with.

Subject: [Milsurplus] An LS-10 Speaker with "built in" Radio Compass
Message-ID: <CABdVoaBuph4ZTung-Q9W8HRY2HyxL9vhhXudak3CmdDiaKRJ3Q@mail.gmail.com>

Here's an odd one.....

https://www.ebay.com/itm/167041736494?_trksid=p4375194.c101831.m47269

Thia LS-10 has had its front panel and speaker replaced to house the radio
compass unit.

I have the radio compass and it has a pair of cinch-jones connectors on the
back.   This repackaged unit has a 7 pin connector on the back,  so I
assume it interfaced to the compass in some fashion. Maybe someone wanted a
portable radio compass?

No idea what the knob to the right of the compass is for, as the compass
dial is rotated by the control on the unit's upper right.

 Forwarding this request to the group. If anyone has one, knows where one is, or knows somebody who does. Stuart would appreciate a call.

Would you, or any of your contacts, know where I might be able to obtain the proximity fuse from a WWII artillery shell (diagram below)?

I've recently come to understand the incredible significance of this prox fuse to the war effort and I would like to put one on display, showing the miniature electronics (especially the tiny vacuum tubes).

This may be a very difficult item to obtain, but I appreciate any suggestions you may have.

Thanks Charlie -
Stuart

 Along with the Atomic Bomb and Radar, the Proximity fuse was one of the 3 technical developments that won WWII. For anyone interested in the development of the Proximity Fuse, please read "12 Seconds of Silence" by Jamie Holmes (Amazon Link: https://www.amazon.com/Seconds-Silence-Inventors-Tinkerers-Superweapon/dp/0358508630 ). Very very readable, it goes into great detail of not only the development of the fuse but also the impact of its development and the impetus of the after war missile development. Few people realize the massive damage that was done to London by the V-1 Flying Buzz bomb and even fewer know how the proximity fuse stopped the V-1 cold in its tracks.

Also, because of their effectiveness and secrecy, VTs initially were not permitted in ETO, lest any duds fall into "nasty" hands. [Deliberate misspelling.] War Dept permitted them only in PTO where they were fired over deep water. Battle of the Ardenne Forest (Bulge) later showed their effectiveness in anti-infantry use when set to fire 50 feet over heads of German forces.

IMHO, attempting to flatten these is futile.
One would be better served to carefully cut-out
some clear flat plastic,? print a paper backing on
photo paper and affix it in that place.? I will be trying
this and perhaps other solutions on an RAS stack.

Did not notice you had attached a picture.
You look for the sockets if the German "Stahlr?hren" *steel tubes*
How many pins should they have? I think they are made from Bakelite...
I will place an advert for you.

Dave ? 

 

How do you know they are bad? Also, it should be easy enough to find good ones and not having to rebuild duds using their bases. Those are pretty common. What are the tube numbers you need? If you need them tested, I can test them for you. 73 ? Mike

Yes, it IS an exercise in futility. It?s a process you cannot arrest.
I once made a laminated photocopy of a label for a BC-1306. It turned out okay, and i sold the thing, but i think if i was
going to keep it, i would be unsettled, and i would look up instead some maker of label tags. They are out there. I even
saw in a ?trophy shop? a couple decades ago, some label work that would make great nameplates for the blue ARC-5
tags.

IMHO, attempting to flatten these is futile.
One would be better served to carefully cut-out
some clear flat plastic,  print a paper backing on
photo paper and affix it in that place.  I will be trying
this and perhaps other solutions on an RAS stack.

Seems to me, it should be completely reversible, like 
uncurling/unshrinking a photograph.

What's lost over time?  Moisture?  Volatile organic compounds? 
Thermo-set at one temperature, which isn't the same as the one it exists in?

What about placing in a humidor of hydrocarbon fumes?

What about processes to reverse the shrinkage of other plastics?

I think we need to consolidate a tons of these things, ones too far gone 
to matter, even just bits and pieces, and spread them around amongst the 
members interested to find a way to unshrink/uncurl them.

I'm thinking, it can't be THAT hard, it's just a flat sheet of material, 
not ash, which is a bit harder to work with.

There has to be a way we just haven't figured out yet.

>Along with the Atomic Bomb and Radar, the Proximity fuse was one of the 3 technical developments that won WWII. For anyone interested in the development of the Proximity Fuse, please read "12 Seconds of Silence" by Jamie Holmes (Amazon Link: https://www.amazon.com/Seconds-Silence-Inventors-Tinkerers-Superweapon/dp/0358508630 ). Very very readable, it goes into great detail of not only the development of the fuse but also the impact of its development and the impetus of the after war missile development. Few people realize the massive damage that was done to London by the V-1 Flying Buzz bomb and even fewer know how the proximity fuse stopped the V-1 cold in its tracks.

>73, Gordon KJ6IKT

I am very surprised to read here the "massive damage done to London". I have a book of about 500 pages on the V weapons attacks; not going to cite its title, as i'm not
sure, and i may have given it away already. The V weapons program were a "massive" waste of resources by German Reich, in terms of the actual paltry returns done to
the  UK industrial establishment versus the resources devoted to their attack. By strict control of the British press, misdirection by feeding false information back to
Germany by British controlled, German spies, the actual damage to UK war production was minimized. If i recall, the Germans also missed going after the radar towers
too, this while the German press crowed about the "massive damage" to Britain and held out the promise for the Reich that 'wonder weapons' would turn the war and save
the Reich. What a delusion.
One thing was learned by the German effort: the viability of mobile rocket launchers. The Allied search for and bombing of rocket launch sites was not very successful. What
really did impinge on the V weapons work was the steady shrinking of the Reich, which necessitated frequent relocations of the equipment. That book i read about the V weapons program gives a practically week by week account of their movements.
Oh - lest we forget - the lives of thousands of slaves, living underground in the V weapons factories, whose lives were reckoned no more value than the  nuts and bolts of the
mechanical assembly.

These song lyrics by Tom Lehrer come to mind:

"When the rockets go up
  who cares where they come down.
That's not my department,
Says Wehrner von Braun."

To be fair, i just read the Wiki article on von Braun, before i let loose this post. He was what you would call, a "complex character". I didn't know that the Russkis, by using
agents in British uniforms, had tried to kidnap von Braun, or his later life religious conversion.

Basically unguided missiles with crude steering devices such as the V-1 & V-2 were, were not really expected or meant to impact the industrial output or the military. They were terror weapons, intended to demoralize the population & perhaps induce them to force leaders to negotiate with Germany. They did deal out death & destruction & were successful in that direction but it seems they only galvanized the sentiments against Germany, so they failed in that direction, too.

Dr. Barry Ornitz wrote about this in several groups about twenty years 
ago.? Do a search on "Barry Ornitz radio plastic" and the same with 
"radio plasticiser" and you will get quite a few hits on his 
methodology.? And of course he had the lab at Kodak to do material 
analysis.? His conclusion was that you can't put the genie back in the 
bottle.? The closest I've come without resorting to etched brass 
material has been by using a a TLC 5500T credit card lamination machine 
with a 15 Mil thickness credit card "pouch".? I had to get a better 
machine to do it well - the first one I bought didn't get the thicker 15 
Mil credit card material hot enough. Below is one of the results, this 
for a WWII pulse analyzer.? (The original is on top...)

How is this receiver tuned? Is it variable tuning ?
I have wanted for years an ARR-16 Sonobuoy receiver. It looks something like an RBM Navy MF-HF receiver.

I have an ARR-3 and a Sonobuoy used with the system. Interesting, but not useful, and so does not contribute to my rent,
and it should go.

Once you've seen a plastics tag that has the 4 screw mounting corners ripped out because of the tag's shrinkage, you will forget any idea of resuscitating the tag.
BTW, i just last night cleaned off a Heathkit HD-1250 dip meter where the black foam insulating material had turned to sticky crumbly. It sure didn't take a lot of 
years for this material to decay. Certainly not the worst case i have encountered; some of this plastics foam turns more petroleum like. When i was still working,
i threw a test set away, sent it to surplus disposal, because the insulating foam in its trunk was that ugly.

Personally, I think the way I'd say it is that Germany "hoped" to strike manufacturing or military sites. The crude guidance devices they used left a lot to chance, at best. And as you say, deliberate misdirection caused the initial guidance settings to become even less accurate & their "chance" went out the window.

The V-2, I can definitely see that a lot of resources went into that project, enough to have made a huge difference if applied elsewhere. The V-1 was such a basic airframe that I'm less sure those efforts would've made much difference anywhere else. As I understand it, as the war progressed, they were turning out fighters faster than they could turn out pilots. Thus, I suspect, the V-1 factories, building a stinker of an airplane, might not have added much usefulness making different airplanes. Your thoughts?

Read some of the posts/forums he was in on the subject, and a lot of 
talk about what is lost, and the conditions, as well as surface 
re-applications of plasticizers.

I didn't happen to see instances of reversal of the scenario, however, 
placing an out-gassing high temperature formed plastic into a low 
pressure/temperature atmosphere, being placed into an atmosphere of the 
lost material, at high concentrations, temperatures, pressures, et 
cetera.  Maybe it's in some forums I didn't come across.

I'm still sure there's a way, might not be the most practical for a 
hobbyist in a condo, working on a dining room table, but it can't be too 
difficult.

Leave a sponge on a table on a hot day, it dries up and shrinks.  Place 
it on a table in a fog, and it gets damp and swells.  Seems one needs 
the right type of fog.

A very worthwhile book, if you can find it, is "V2." Written by von Braun's boss Gen Walter Dornberger, it's a detailed study of the WW2 efforts by the Wermacht (?) to perfect Werner's "hobby" for military use in the 1930s and beyond.?

I am sure the testing of the proximity fuse was an interesting process.  In a 5 inch shell, it accelerates from 0 to 2500 FPS in 22 feet, so the G forces on the electronics must have been crushing.  But lets move up a few years to 'Atomic Annie".  So, we put a nuclear weapon in a howitzer and fire it.  I am sure the testing of the projectile and fusing was done over and over to the Nth degree before they put the nuke in it.  Still, I can envision the fellow pushing at the control shack, keeping his eyes closed,  and cringing with  his other hands index finger in his ear as he mashed down on the fire button. At least it was electric, and not some poor troop standing next to it pulling a lanyard.

Here are two photos.
I have two Siemens KG32 GWB
Morale receivers which use 1.5V
filament valves:
DCH11?? Triode/Pentode Converter.
DF11? IF Amplifier
DAF11? Diode Detector, Pentode 1st Audio
DL11? Audio Power Output.

1S4 works well to sub DL11.
I'll be trying 1V6 for Converter,
1T4 or 1U4 for IF and 1U5 or
a sub-mini (forget the number)
for Detector/First Audio.
Both of these sets have been
"golden screw-drivered."? One
was presented as a "parts" radio
at the auction but I believe it to
be recoverable.? Most of the
slugs in RF/IF coils have been
broken but I found a way to
get around that I'll write up if
and when I ever finish these
things.? I don't get a lot of
"play radio" done lately.
Thank you kindly for your help!

There is no need to go to a 1L6 or 1U6  for converter when a 1R5 will do. Or a transistor sub for the 1L6, which you can buy.

Good news for you, Wayne! The stickiness may come back to visit !
I had a, i think it wa, model G5 'Buzz Aldrin' multiband radio with the same problem. I thought about it and read about it, and decided that was enough 
for me. I gave the radio away; i did not want to deal with this again. And YES, it had been stored inside, room temperature, and i was the first
owner. It got the disease in about 5 years. 
I have 2 of Panasonic RF-5000, a large portable multiband radio. One has sticky and one does not. The sticky one was stored in semi - outside storage,
subject to large temperature and humidity fluctuations. This does not seem to be a necessary requirement tho. 
I have felt cords from WW2 era, both headphone and power cords, some sticky, some not. And radios and test equipment of less than 10 years old when
this first appears.

Just did a video on the Colins KWM-1 transceiver, so it's not strictly a military radio but was used in early U2 flights and may have been tied into Curtis LeMay's thought process into adaption of SSB into US Air Force use. For a radio built for the Ham radio market it has much more in common with military radios then Ham radios of that time.

Good Evening All,

        I have to radically down size my collection of parts, test
equipment, speakers, Etc. So here is the drill. On Saturday November 30th
and Sunday December 1st. I will have my doors open for any and all who
wish to stop bye. Most items will be FREE or make and offer. I have a set
up that needs to be taken. This is a Five foot rack, with an R-390/urr,
TMC SSB adapter,Speaker so make me a reasonable offer. I can supply a
photo of the rack and radio.  All items are pick up only. Please contact
me for my location as My new address is listed on QRZ and the FCC data
base. I really hope I can have many people come and get item, otherwise
its off to the scrap dealers.

Thinking of trying to clear out space in the shop for a second work bench. Have an equipment rack that has a Collins ARC-38 CW/AM Transceiver with head, 180 Antenna tuning unit and power supply all set up and working, along with a ARR-41 receiver that's all original with solid state power supply or the original dynamotor supply if you wanted to go with that in the same rack. Options are to disassemble all this stuff and store it but would much rather sell or move it all to someone else if they were interested.
A video from the last time I was using it five years ago:

https://www.youtube.com/watch?v=HD2Y-zEcvKE&t=113s

Have a couple spare radios, other parts and all documentation that would be thrown in with it, open to offers at this time.
Another alternative may be to get something like a S-280 Shelter and relocate all the Ham radio operations out there? Just that its getting old only having space for one item at a time on the workbench and projects are starting to back up around the shop.

I have an "extra" lone GRC-109 transmitter. I concluded it would not be best use of my time to try to "complete the full set".
This is not a giveaway. I am open to offer. I will take a look today and see what overall it looks like. Not beat up.

Message-ID: <CABdVoaBQa8+K6Hcd3NXxQFarmd27Dua6VgLxgNtU=n6iNrW0uQ@mail.gmail.com>

I am running cables for the 2KV and 500V TBW Power Supplies and I was
looking for a way to provide a strain relief for a Millen HV connector with
parts on hand.

I found using the soft outer plastic shell from an old microphone connector
works great. The electrical tape securely holds the shell to the HV
connector while allowing the shell / connector to rotate freely around the
HV cable.

Just a word of caution from experience. Back around 1970 I had a KW amp with a separate PS. I believe it used a pair of 4-400s. In order to go from class C to linear, the drive had to be changed from one connector to another and they were SO-239s on the amp. They were spaced about one inch from the Millen HV connector. So, one morning before work, I decided to go from one mode to the other, without switching off the HV. Done it before several times with no problem. I unscrewed the PL-259 that was 2 inches from the HV connector and as I was putting it on the SO-239 one inch away from the HV, one of my fingers holding on to the PL-259 touched the Millen HV connector. The whole connector literally blew up. Thankfully my other hand was not touching anything. So, there is smoke and a lot of strong smell of burnt flesh. I was knocked on my ass. As I managed to get up and walk around in a daze holding up my hand still smoking, my wife at the time comes into the radio room and asked if I got a shock. A couple of weeks later I was working on a low voltage solid state PS and something fell on the large filter cap that sounded like a gun going off. I almost had a heart attack and looked behind me to see if the HV supply was still on the floor or came after me, HI. True story. Be careful. 73 ? Mike

Subject: [Milsurplus] GRC-9 Bias Battery
Message-ID: <DM8P220MB0472526217307419A3621666B8272@DM8P220MB0472.NAMP220.PROD.OUTLOOK.COM>

Just started doing awork on a bunch of GRC-9 transmitter / receivers. Never spent much time on them before but getting an education now. The big question for today is the receivers bias battery, lot of stuff on line about this from its only there to improve audio response to it is limiting current in the audio output tube and absolutely necessary.
It only provides cutoff voltage to the audio output tube, nothing else. I have seen where people have built up battery packs and all sort of stuff but when I look at it am going to assume it draws almost no current at all in normal operation thru grid current. When the radio is turned off no current is drawn, unless something like C54 gets leaky So why use big cells (AA, AAA) for this and just stuff a lithium 3.6-volt clock backup battery in its place?
Would look a lot better than some clump of AA cells and can fit in the original holder. The other option is to just use the radio without the battery. Cannot hear any difference between the audio with or without the bias.
Another thought, if you don't use the battery should you jumper C54 to ground to prevent any positive DC voltage from developing acrost the grid of V6, maybe a 1.0 K resistor to keep you from grounding the grid?
So, lets see what the prevailing opinion is on this?

Would the small "coin" cells be useful for bias battery replacement?? I know they are available in 1.5 and 3 volt types, the holders/sockets are not much larger than the batteries, and have solder tabs.? Both the cells and the sockets are very inexpensive.

My recollection is that the original battery was 4.5 volts, so you could put three 1.5v in series or a 1.5 and a 3v in series to get exactly what is needed.? I think there are taller sockets that will hold a stack of these cells - if you can find one that would hold three 1.5v cells it would be perfect.??
I have also had success stacking several coin cells, placing stripped hookup wire against each end, and putting heat-shring tubing over the whole business to pull it all into contact.? An example of this is right here on my office desk - a small stack of coil cells powers the code practice oscillator I mounted on a key base for people to play with.? I send a little Morse to them if they seem interested.? Here's a photo showing the heat-shrunk battery pack in the lower right corner:
http://www.wd8das.net/Office-Key-2.JPG
I have more often used these coin cells to retrofit into a radio with a dead memory backup battery.? Often the original type is obsolete or hard to get, so I usually select a more common type of the right voltage.? Size might not be exactly right and I can't mount the new one exactly like the old one, so I end up connecting the socket to the board with hookup wire, putting the battery and socket into a small ziplock bag to insulate it (and maybe catch any future leakage), and tuck it wherever I can find some space.

My understanding is that with an expired bias battery, but of course one that still has some DC resistance, the maximum audio output is limited,
for speaker output, and distorted at higher, non headphone level. I cannot remember actually verifying this myself. But the receiver will work with
an expired battery in place.
I sold maybe 4 GRC-9 last year. With each, i provided a small 3 watch cell holder. This holder was about ? inch diameter, so it fit well into the
battery space. I bought the holders and cells from China ( naturally, and with some regret of course. ) The holders are quite compact and not
heavy duty at all, but how often do you have to change the cells, at 0 uA draw ? Another thing i got ready to try, but never did, was to use a standard
9 volt radio battery, with a high resistance divider across it to deliver 4.5 to the grid. The divider resistance would be in the low megs and the
divider current, altho continuous, is in low microamps, so the battery can be expected to last a long, long time. I kind of prefer the 3 watch cell
holders i have though.
Richard Brunner pioneered the use of an LED to illuminate the receiver dial instead of the feeble pushbutton operated dial lamp. You interrupt
the B+ line in the receiver and the LED runs in series. This costs you of course ~3 volts from the B+ for the plates, no big deal. I have, i think i can
find, Richard's summary of the process and i will forward it on request, or if it's a small file, i will post it here. I later looked into "string LEDs"
as a further improvement but i never actually put such in a set. I think this style LED has much promise. If you replace the feeble #49 lamp you
will love the lighted receiver dial, no lie. None of these LEDs cost any money; you just might have to buy 20 or so to get 1. You then have the dial
light pushbutton to devote to some smarter use.
I am letting my impoverished brother sell off some of my collection. His attitude is "Sell, sell, sell!" while my attitude is, "Let's think about that a
minute." We sold off 2 of my best GRC-9, one a Hoffman and one from the rebuilds Fair sold, which  was especially picked out. I also foolishly  sold
one for a nothing price at a hamfair, and then sold 2 to a ham radio acquaintance, which i'm sure he flipped, as well as the stack of boat SSB
radios i gave him. Live and learn. I am not a fast learner, but i learn very well, with an indelible memory for some things.

Antother thing you can do for dial light is to use one of the Chinese ( of course... )  "pencell flashlight bulb" replacements.
These use an LED but include in the same size bulb package, a small relaxation oscillator to boost the 1.5 volt supply source
to the ~2 volts the LED wants. You can actually force fit and bend flanges on the original dial light holder to hold such item,
or you can solder it in. Richard Brunner found that you actually do NOT hear any spurious from the LED voltage boost circuit.
This too works pretty well, and is pretty easy to implement. A lighted radio dial is part of the magic.

More GRC-9 questions! What type Neon bulb is I101, that's the neon bulb that you tune to max. Think it's a NE-47 but not certain.

Commentary and opinion beyond this point, if easily offended do not read!
Ok, I get it that you needed some method to tune to max, the old WW2 stuff always used a antenna current meter and for some reason in the fifties there was by cost cutting or because of size restrictions the idea of using a neon bulb to tune to max bulb. These are field radios, to be used in the field or attached to a vehicle for use in the field. How in the Hell where you supposed to see this little neon light in the daylight?
Ok, so maybe the big black tube around the bulb helps and will admit that until I started this project never used a GRC-9 before, although I now have like five of them in the shop all at once but just looking at it have to wonder how that was supposed to be used. Speculation is that you would drag out a field strength meter and tune the radio that way. Just using vertical output have no issues generating power into a fifty ohm load and inside with the one good neon bulb I see it ok but already know where you set the antenna tuning control has a big difference in output power and with a week display like the original design have to wonder how this is used outside in the daytime?

guys I could never get my bulb to glow bright  while tuning up even after changing the bulb twice from other sets I was using the dipole.  not sure if it had to do with low impedance 75 ohm antenna   Jeff

Looking at the picture of Tim?s set figure he has got to be using some kind of Atomic or Nuclear bulb in his set! Got a couple more NOS bulbs coming in and will see what happens, also noticed that a couple of the VR150/0C3 tube wont fire and starting to think maybe this is all because after seventy years the gas leaks out or something?

Hi Ray - Yep, the lamp is a cheaper, smaller, rugged but effective tuning indicator.  Much more light output than the typical NE-51 pilot light...Quite bright in daylight in Hi Power CW, less so in low power AM but mine is still quite visible outside.  The cross-polarization light attenuator would be very helpful at night...
Here's a shot of mine lit while indoors: https://www.n6cc.com/wp-content/uploads/IMG_3953.jpg

Figure I would post a couple pictures of some of the radios that have been under discussion. This is the French set with the one good bulb that I have now. It appears brighter in this picture then it doses in real life but maybe that?s something wrong with me, who knows? The picture was at 7.0 MHz at around twelve watts into fifty Ohms. Still get good glow in HI/Low CW and AM so think new bulbs will help the other radios with week or non-working bulbs I can swap the good bulb around and know the issue is the bulbs and not the circuit. Same thing with the VR150/0C3 The next issue is gaining access to the band switching assembly in one of the transmitters to try to clean that up. So far, I have not come acrost any Whisker Growth but have noticed that the Frenchie was never shot with MFP like all the US sets and have some issue with corrosion throughout the receiver. It has good sensitivity on band one (40 meters) but sucks on band two (80 meters) and band three. Also noticed on the receivers that they appear to have an issue with strong signals pulling the osculator, it?s that or the backlash on the tuning not right but it?s annoying when tuning and the signal appears to shift up or down. Although it?s only a small amount still not right. Anyone else had issues with backlash on the receiver?

Ray,
I see you are using a PP-327(A or B?). I just acquired a "B" unit of
unknown provenance that had the power cord cut off, but nearly pristine on
the inside with the exception of seeing the blower motor disconnected. When
you acquired your power supply, did you completelyre-cap before applying
power? I see the warning in the manual to never power up without a load (or
radio) attached; but want to get some insight into what to expect before
applying power.
73,
Matt

The PP-327B is on loan for this project, the story I was told is that it was NOS and never used and is very clean. Because it appears to have never been used, I did check all the DC to ground resistances and also connected a external power supply set to 3.0 volts with current limiting to the Low voltage - filament bus. That's the junction of L3, L4 and C7 and let that cook for a day to reform the three huge capacitors (C6, C7 and C8) and then did HV checks with an external capacitor tester, a real capacitor bridge and not some little POS digital tester and ran them up to working voltage to check C1, C2 @650 volts and C3A and B @200 volts.
Think after that it's all ready to go. Have to say the PP-327B is uptown with its B+ regulation and clean design. Like that box way better than the stock 327
If you don't have it download TM-11-5070/ TO-31R2-2GRC-9-21 from Radionerds

Is anyone interested in a 400Hz 120volt Dynamotor and a 800Hz 120 motor
generator?
Input is 24 volts DC at a few amps!
They're used!!   Bought them at Jim Dunn Surplus back in the day

I used a 24 volt 50 amp power supply to run these things.  That's available
too and it's heavy.

The price is you pick them up at my home.

I can't speak for the GRC-9, but have some
experience with battery sets.
In many of those which use a bias battery,
if one runs them without proper bias voltage,
one risks blowing-open the hair-fine
Audio Output transformer primary winding.

That's right, Dave. Those primary windings are #40 wire.

Wow, Energizer Industrial Nine-volt batteries are easy to open and do provide 1.5 volt cells that can fit into the plastic shell of the Bias battery on the GRC-9, they also have tabs attached so you can solder them. I know what I will be doing this weekend!
Going to rebuild the bias battery and am taking into account everything that has been said so far. The manual says that the battery is needed for improved audio response although I think that's a bit of a Red Herring. Looking at the plate current curves for the 3Q4 I am more inclined to think they had the tube biased that way because the plate current is half of what it is with no bias and being the audio output tube draws more current than any other tube in the radio, they did that to get maximum life out of the B Battery if you were using the radio that way. Remember that the receiver was capable of running from a dry battery pack in the field where you would only have to crank the generator when transmitting. Overall current drain in receive would be a big factor and the designers of old were skilled at building battery powered radios that got long hours of operation from dry batteries. I had a TBX-6 that only drew about 10 Ma @ 90 volts for the receiver and was always impressed that anything can run using that little power.
In regards to the gauge of the wire in the output transformer I have a hard time imagining it being 40 gauge, but if it is 40 gauge is only rated for about 15 Ma, it's only a guess on my part but I would think more along the lines of 24 or 28 gauge and that is good for around an amp. But that's just my speculation and as my wife will be the first to tell you I am often wrong.

Some of the manuals actually tell you what gauge wire the transformers use. I am confident the primary of the high ratio transformer
does not have the first digit as a "2". More like No.38 or smaller.

Subject: [Milsurplus] Chineseium Plastics & Polyimers
Message-ID: <733cbc62-4c8b-4e52-ad5a-f932b70b6837@localhost>

The Chinese have a long history of leaving expensive stabilizers out of their plastic or polymer products. This is why, when you buy a refrigerator, the shelving in the doors lasts about 6 months and then starts cracking and breaking. This is why your radio develops the sticky-icky problem.

Even worse, metal canned food spoils much more quickly (you can taste the metal), because the cans are made in China, and the polymer coating that's supposed to keep the food away from the metal breaks down in short order. My family has gone to canning with the glass jars, but even there, the red sealing polymer on the lids is also chineseium and breaks down much more quickly, losing the food inside after only a year or two. We're busy trying to find an American-made lid for canning jars. Yeah I know - good luck finding anything American-made today.

Hi Mark,

Mobilith SHC 100 has been recommended several times in the past several
years.  I tried it with success over 20years ago but in those days it
tended to separate in storage.  I bought a new tube a couple of years ago
and the new one has not leked red oil, thank goodness.

Hope this helps.

Clare. N2RJB

The separation is why in past emails I've suggested laying it flat in 
the refrigerator, in a ziplock bag.? Same thing happened to me, and 
reducing the head pressure seemed to solve it.? But there is a better 
version of it out now, one that uses a much more modern thickener made 
of polyeurea - same Mobil company.? It's called Mobil SHC Polyrex 102 EM 
(EM stands for electric motor).? I got a tube of that four years ago and 
it will protect your dyno bearings even better than the SHC-100.? It's 
come down in price - about $14 on Amazon.

Keep in mind that some later dynos may use permanently sealed bearings, 
so you won't need to/cannot repack them.? :-)

Ok, for one or two people out there who may have been following me on the latest GRC-9 adventure wanted to post an update and a question. Four sets came in, three US and one Frenchie. Two of the sets are done, cleaned up, calibrated and all that sort of stuff and are ready to go. But two are still on the bench. One transmitter has a band switch that refuses to work and the other a Cincinnati Electronics receiver has an issue with backlash. This appears to be the newest receiver and works well except the receiver has an issue with backlash when tuning. On AM it's no problem, espicaley with the huge Barn Door wide IF in that receiver but with no separate BFO you have to use the tuning control to set the beat note in CW, its important because with a wide IF and high gain receiver in the CW sub band you can often hear two or sometimes three stations at once so having the ability to set the pitch of the note is important. Would have thought that maybe it's just the design of that radio but the other receivers have good response on the tuning, even the French receiver. So, I cleaned the drive gears, lubricated the bushings that support the main drive shaft and the ball bearing on the tuning capacitor but still have the backlash issue. There are just two gears, the main drive shaft and the gear on the tuning capacitor but it's like I have too much of a load on the capacitor or maybe excessive gear ware or something that I don't understand going on here. Any ideas on what I should be looking for? Is it possible that Cincinnati Electronics just built these things this way? Anyone else had this issue with that receiver?

Dave,

Here's the impedance of the output transformer used on the RAS. Hope this
helps.


Thanks,
Konrad

I know Ray is on here somewhere, but could not find an email I saved with his email address.  I was looking for some info on a vintage radio and in the images up came this:   https://staff.salisbury.edu/~rafantini/IMAGES/ARR-41/arrdyno.JPG   What is interesting about this, is that it says it is from Salisbury.edu, and while the address points out ARR41, the picture caption is BC348.  Don't know if you are privy to this posting by Salisbury, but maybe you want to let them know.

Wow did not know anyone looked at those web pages anymore! Keep that page up on a server at work so I can set it as a home page on my web browser. Makes regularly used links fast. Was thinking that I would go back and delete a lot of that stuff because in the last five years have migrated somewhat over to doing videos on You Tube. At one time I owned the WWW.KA3EKH.NET<http://www.ka3ekh.net/> domain but didn?t know if the payments were still current or where that stands today, had a DNS redirect that pointed to a university server if you used that address. Problem with that was that the redirect lived on one of Al servers at QSL Net and that?s long since been sold.
I am looking at retiring in the next year or two and don?t know what I am going to do at that point. Not going to have access to any of the servers beyond that point.
