TR1196 HF radio control unit

[yahya]

I am looking for a sketch or image of the TR1196 HF radio control unit. It belonged to the transceiver, which covered 4.3MHz-6.7MHz in maximum of four spot channels. If someone has it, it would be appreciated if the image could be shared on the forum.

The control unit that appeared on TR 1196 – PA0PZD – Signals Collection may not be exactly from the TR1196 set.

Another image from an RCAF Lancaster showed a HF and a VHF radio control units, which look almost identical. Source: AVRO LANCASTER BOMBER - WWII ERA ELECTRONICS FIT

Did the 'HF' marked control unit from the RCAF Lancaster indeed serve the TR1196?

Thank you for the reply. Unfortunately, none of the links provided an imagery of the control unit for that very radio set.

Found one reference that said it could use the same control head as the SCR-522, which was the the BC-602-A

Right. It seems that the TR1196 used the Type 4 Electric Controller. I am trying to find a sketch of that control unit.

Edit: found this:

Ah .. the switch control box was almost the same for most of the RAF planes. These differed from variants with the shape and number of the connection sockets. These can be found both the fighter and bombers ...

These control units differed a little bit. The one that you depicted was Type 3 for the VHF radio, the TR1143. It had a small latch, perhaps a locking unit just over the T-R-REM toggle switch. Type 4 control unit did not have it. I also assume there were some minor electrical circuitry differences between the Type 3 and Type 4 controllers.

Figure 8-8, of Section 8, pdf page 175 has the BC-602A dimenstions.

And here the Type 4 selector also used for the Spitfire ...

As for the Canadian Lancaster cockpit photo from TR1196 HF radio control unit, the HF radio control unit was Type 4, while the VHF control unit was Type 3 as it had a small locking latch visible next to the T-R-REM toggle switch.

 

[Wurger]

Both look the same IMHO. Just the HF box is turned 180 degrees comparing to the VHF one. And the locking latch seems to be moved towards the T-R-REM toggle switch.

Also see my post above.

 

[yahya]

I would dispute that. See my comment in: TR1196 HF radio control unit.

The VHF control unit has two small metal latches or hinges, while the HF one has only one. The upper one was to control the brightness of the glowing bulbs, which was very useful especially during night flights, when you had to reduce the brightness to the minimum.

In addition, the VHF one has a locking mechanism for the T-R-REM toggle switch. The HF control unit does not have it.

 

[Wurger]

I think you are right. Having a closer up look at the box I would say the light spot next to the T-R-REM toggle switch of the HF box is the "T" letter of the inscription there. Also the pics of the Type 4 unit don't show the locker.

 

[yahya]

Correct. The T-R toggle switch changed the mode of operation of the radio from Reception (R) to Transmission (T) if the remote Press to Transmit (PTT) button on the control column was not available or working.

This illustration comes from an article I researched and wrote, describing the communications equipment used on the Supermarine Spitfire: it's a little disappointing that you didn't at least acknowledge the source. Thanks.

Here is manual for the TR 1196. I may have one for the controller as well but I am about to go out for the day so do not have time to check.

Ah .. I do apologize. Sorry, I haven't seen your article. Just found it some time ago as the pic only. I just edtited that.

Guys, do you happen to know in which radio installation the Electric Controller Type 1A (10J/7) has been used? It resembles the Type 4 controller from te TR1196, but has a rectangular connector. IWM suggests the TR1133.

No real problem; as long as people realise that I worked hard on that article (and still managed to leave out some details...see below)

Yep, the Type 1A was the original control box used on the TR1133 (I'll have to revise my article to include this). The bayonet fittings at the back were replaced by a round, universal socket on the Types 3 and 4 Controllers.

As to the Type 4 controller, things are a little bit murky.

Long story short: rather than continue with development of an unreliable VHF set, the Americans arranged to manufacture the British TR1143, using American components and manufacturing techniques: this was the SCR-522 series, as fitted to Mustangs, Thunderbolts and Lightnings. Along with the SCR-522, the Americans also used the Type 3 controller as the basis for the BC-602 'Control Box'; again, using American components and techniques.

In turn, SCR-522s were supplied to the British under lend-lease as the TR5043. The associated BC-602 control box either became the Type 4 Controller in RAF service, or the British manufactured their own version of the BC-602 as the Type 4, to be compatible with both the TR1143 and SCR-522.

A really useful site to consult is SpitfireSpares.co.uk, that has photos and some details of British/British-American radio equipment.
