T1154 and keying of same

I remember as a RAF Cadet in 1958 using a R1155/T1154 combination on the RAF net. Every time you pressed the key a large relay clanked on the top of the TX. I recently read that sometimes because of the finite time it took for the relay to pull in ,the first dot could be lost or the first dash shortened. Is there anyone out there that actually used this kit in Lancs and could confirm or deny this.
Was it just an antennae changeover relay or did it actually switch some part of the circuit on or off. I would be very greatfull for any information.
(Incidentally I do get out quite often, I am researching this to clarify another historical event. !)
Many thanks.

Re: T1154 and keying of same

Ken,

can't tell how things worked operationally, as I wasn't around. I can tell you what the key does to the Tx, as I have just added AP2548A Vol.1 Ch.1 to the VMARS website (where anyone can grab a copy if so minded). This has all the circuits for each model.

As you rightly say, the key controls a keying relay (designated A/12), which switches the following items between send and receive modes:

a) the MF aerial between the Tx o/p and Rx i/p
b) the HF aerial between the Tx o/p and Rx i/p
c) the phones between the Tx sidetone and the receiver audio
d) with the key down the negative bias on the Tx valves is removed thus producing output

Re T1154 and keying of same.

As a signaller/gunner flying in many aircraft [Lancs, Lincolns, Ansons, Varsity, Valetta and Shackletons] equipped with the Tx1154/Rx1155 combination I can assure you that I never noticed any problems of this sort. The 1154 was a very reliable piece of equipment........although the aircraft Morse keys left a lot to be desired!
Hope that helps.

T1154 keying.

Ken.
I don't think you will find may old timers left who flew on Heavy's during WW2, but for what it's worth, I spent 5 years as a Wireless Op with the RAF in the 50's. The T1154 was well on its way out at that time, and although it had done it's job to perfection throughout the war, there is no escaping the fact that it is possibly one of the crudest designed transmitters ever built.

The relevant AP reference to the 'Magnetic Relay type 85' specified that it is designed to operate at speeds of 25 WPM or more. Given the distance the contacts must travel and return each time the key is depressed, and the simple mechanical design of the assembly, this estimate seems absurd to say the least. A good wireless operator could send at 25WPM using an RAF type 'D' ground station key, but not on an aircraft Bathtub key while wearing leather gauntlets.

After a great deal of careful contact adjustment on my own treasured T1154, the best it can do is 15 - 18 WPM, with a regulated 6.5 Volt supply for the keying voltage. The relay undergoes a full movement each time the key is closed, so the problem of clipping a dot or dash would not be confined to the first character sent, but would continue throughout the transmission.

Bendix RA-1B receiver

There is a reference to the Bendix RA-1B as the receiver installed in Amelia Earhart's plane on her unfortunate around the world trip. It's message 10 on the following website:

http://www.tighar.org/forum/Highlights101_120/highlights105.html

The other messages are all part of a discussion of her last flight, which I did not read.

In general, the receiver is for installation in aircraft. Presumably, there was a companion transmitter, but I don't know what it was, and I am trying to find out all I can about both. Perhaps someone can add to my meagre information.
Hope this helps.

Re Bendix RA-1B

I also have a RA-1b in working condition.
I obtained it about 40 years ago from the Airline
I was working for ( T.C.A) complete with schematics.
I have been unable to track down if TCA ever used it
on their Lancasters or Lockheed 10's but still trying.
The companion xmtr was the TA12. The rcvr could be used with a cable connected remote head and also
antenna switching from D.F/trailing antenna/fixed antenna.

A prototype model (RA1) which I believe only covered
up to 7.5meg was installed on AEarhart's 10E aircraft
along with the RDF loop ant.

RA-1B receiver (posted by Don)

Yes ! This black wrinkled painted wonderful receiver was used on Lockheed Lodestar aircrafts (BOAC) during the early part of the '40.

I used to repair them when I was at the Almazah RAF air-station, (Radio Shop N�2) when the aircraft had to undergo a "CHECK-4" or the more stringent overall of the "C of A".

Almaza base was, and I guess still is, an extension of Heliopolis, next to Cairo. Further away was the US Airbase called JOHN PAYNE.

WWII radar operator

Dear Karen -

My father was Larry "Al" Wilkinson, a sergeant in the 1st Marine Div., 12th Anti-Aircraft Battalion. He was stationed on Peleliu in the S. Pacific.
His radar trailer unit was set up on the SE tip of the island. He was 19-20 at the time.

I don;t remember that he mentioned anything about the glowing tube thing, but I think the radar screen itself was a primitive tube, like a TV
tube, but simpler. I think the screen was coated on the inside with a chemical (something that's fluorescent when the electrons hit it) so it
would glow a little bit to show the targets. Does this sound right?

I haven't learned much about it. My dad wouldn't talk about it for
years. Then we'd mostly try to ask him about his experiences, rather than the technical stuff. He died in 2000, but I think he felt good that he was able to talk about it, and meet up with some other old Marines.

I'd like to know more about this, and the men who ran them.

Thanks- Craig Wilkinson

Hello,

My father was a member of the 562nd and later the 582nd SAW Battalion during WWII. I believe there were some other names for his unit as well, maybe 2691st and 734th? He served in North Africa, landed on Pantelleria and continued on to Italy and France. He was a radar mechanic and I believe his military occupation number was 514. I do not recall how I came upon this site and your address. I had it bookmarked some time ago. I would be interested in comparing notes with you.

582nd Signal Air Warning Battalion

My grandfather (L. B. Krauss) served during WWII for the 582nd SAW and spent about 2 years in Europe (Italy, France, Germany) from 1943-45. He passed away very young and long before I was born so I've always been curious about him. My grandmother and mom remember that he would never talk about what he did over there and always joked to them that all the guys "just played baseball the whole time", which we know really wasn't the case. I've been searching high and low for information on his unit and can't really find too much about them. Any information would be wonderful!

562nd Signal A.W. Battalion

Hi,
I saw your message about your father being in the 562nd. My father was in that battalion as well. I've been trying to research what he did in WWII, but haven't had much success. My father passed away when I was a boy, 38 years ago, so I don't have a lot to go on. I wanted to ask if you've found any good websites regarding any kind of history of what the 562nd did in WWII. My father was listed as being in the headquarters company. I tried to get his military records from the National Archives, but they said the records had been destroyed back in 1973 in a fire. Any leads would be most appreciated.

Thanks

Women's Air Raid Defense, Hawaii 1941-45

I am writing a book on the Women's Air Raid Defense, this was a group of
uniformed-civilian women who took over the Information Control Center at Fort Shafter,
Oahu, Hawaii. I have interviewed several of these women and have been able to ascertain
history, development, life styles of the WARDs but none has remembered the training to
become a radar plotter with any detail.

I have contacted Fort Shafter and any manuals or training modules of 1940 are long
gone. Can you direct me to or do you have information about the nitty-gritty of their
jobs?

For example, one of the WARDs told me she plotted her husband in from Midway and
knew that he had crashed. (He survived and went on to win the DFS.) When I asked her
how she knew it was Bill's plane, she replied, "He wasn't on the board anymore." But
she couldn't explain to me what that meant. "It wasn't my job to post on the board."

I've asked about the training, but they all remember the strange names for the
quadrants, and the military protocol, uniform-measuring, hearing tests, but that's it.
Those are significant details, but I still am not at the meat of what they did.

Could you please help me?

Radar during WW2

My connection with Radar. (RAdio Detection And Ranging)
made up the name with the capital letters RADAR.
I started in 1943 in Tampa FL. with the original SCR 270.
This was a very limited unit, limited to only detection.
After training on the 270 for a year. It then had a set date POE E (Port Of Embarcation for Equipment) followed
closely with the POE P. P for personnel (which included me.) The design engineers had perfected Friend or Foe.
As the name indicates: Is it one of our planes flying into our area or is it one of the enemy? NO WAY will we send an obsolete Radar unit into the war zone. Then we saw
trucks arriving at Camp Murphy, FL with the parts for the new units with FOF. This happened again when Height
Finding was added for the Anti Aircraft boys to be ready
to shoot down the enemy. I started over three times.
As a result I was never sent overseas...the WAR ENDED !!.

Re: bc191x model 24 volt.

If the unit has power and output connectors also on the bottom of the set it is a BC 375.If it only has connectors on the side it is a BC 191.The BC 191w was used in vehicles while the BC 375 was for aircraft.

Was the BC 191 - BC 375 a Lemon ?

Hello to all from Australia ,
I have a BC 191 here and A few people have said the set was a lemon , not very useable on the ham bands . Does anyone else have a opinion ? The set is a MOPA design using four 211 tubes . I believe the VFO 's in them were very unstable , they certainly are a weird design .

I know some hams did use them on air , but with modified VFO's . Does anyone have details of the mods ?

I plan to install the set in my 1/2 Ton Dodge Command car but need the 12V dynamotor and plugs etc. At least it will look great . The BC 312 is a nice rx , no problems there .

Thanks for any replies , Mike VK3CZ

BC375

You can find the entire manual on <http://www.kg7bz.com/manuals.html>;.
To change frequency you have to use different tuning units. You can also change some materials in the tuning box to get on your frequency.
All I know, it's a nice machine. I used him for transmitting on the medium wave (TU 5B tuning unit)

Good luck

BC375 stability

You have probably had many answers by now. The BC375 was very unstable. Modulation ended up being a mixture of AM and FM, about 20 kc wide. That's the bad news. The FCC got after a few hams in the US for using them on the air.

Now the good news. AfterWW2 Air France installed thm on Connies for Atlantic runs. They had one good feature. On CW they didn't arc over at high altitudes The ART13 did that they used. I used to work in Maintenance for Lockheed.

Re: BC375 stability

by William Donzelli

The BC-191 and -375 really do have a bad reputation. They actually do work fine on 75m if they are used properly and all of the rules in the manual are followed concerning the power supply and neutralization. If you cheat, you have troubles.

BC-191

HI,

I am a collector of old military radios and I am brazilian.
I have one BC-375 in my collection( the same as 191, but the 375 uses 28 volts) and is no good for ham use as the VFO is unstable and difficult to mantain QSO on AM.
I believe the ART-13 is better and stable...
My experiences with the BC-375 was not satisfactory.

They have two languages because they were made in USA for Lend Lease to Britain and Russia.Few went to Russia because the US government knew that Russia would never pay for them.

Dear Pete,
I have a relative who lost her husband on 7th Nov 1944, he was James Frederick Dines, Sergeant 746565 of the RAF Volunteer Reserve B.S.R.U unit, his ship hit a mine on that day in that area so it may well be the same ship. I would like to know more details of this event and the purpose of the B.S.R.U. unit at that time if possible. I can then pass any information on to his widow.

LST 420

Some details of the sinking of LST 420 are contained in "Ships Without Names" by Brian Macdermott ISBN 1-85409-126-3 published by Cassell 1992. My father was on LST 367 which drifted between the two halves of 420 and picked up some survivors - this was either brave or stupid by the skipper of 367 (Lt Comm Page) since this was in a howling gale and in the middle of a minefield !

LST 420

Just in case anyone is still interested - my father was one of the 26 ORs rescued from LST 420. He said in some memoirs that the RAF personnel formed a mobile radar unit sent to support the allied offensive in europe. They had developed radar, operated from the back of a "Bren gun carrier", to detect low flying aircraft and tanks. He was incorporated into a new unit and flown into Belgium a couple of weeks later.

and
my only notes say...
GL3
Two CV22 thyratrons were used to generate a 40A/25kV 1�s pulse at 400pps for the GL3 S-band radar.

and finally I once received from...
Fred J. Heath
At Royal Canadian Air Force, where I became the resident engineer at Research Enterprises in Toronto, where the Canadian government was manufacturing radar equipment basically to the British design: initially, the ASV equipment and also gunlaying equipment equipment that used two separate antennas, one for transmitting and one for receiving. They had operators who maintained the direction: one operator for vertical and the other for horizontal direction. It gave, I would imagine, about the same sort of performance as they had with the 584. This was the GL3-C I think they called it. And they said that without radar it took about 2,000 shells to bring an enemy plane down; with radar they could do it with about eight or ten. [Chuckling] They built about 660, I think, of those GL3-Cs and shipped them over to Britain and, I guess, to the continent.
