R1556A/AR88 transmitter
Just as a matter of interest. Does anyone know if there was a companion transmitter that went with the R1556A/AR88 receiver. As I have the receiver, the addition of the TX would make a great combination.

Re: R1556A/AR88 transmitter
I suppose there are 2 ways to look at this question:
1. Did RCA produce a companion transmitter to the AR88? 1. Did the RAF intend to use the AR88 (in its R1556A guise) with a transmitter?I have no idea of the answer to 1 but it's my understanding that the R1556A was mainly intended for use by the RAF "Y Service", where it's purpose would have been to intercept enemy (mainly German) transmissions. In that role there would have been no associated transmitter. Hugh |

Re: R1556A/AR88 transmitter
The AR88 was produced as an amateur receiver, but was seen by the military as an off the shelf solution when they required large numbers of communications receivers in WW2. It does incorporate RX/TX switching, so it's possible that RCA made a companion amateur transmitter. This would have been unsuitable for military use though as it would have covered the wrong frequencies and in most cases AM wouldn't have been needed.
The three services all had their own design of transmitters, but I don't know what would have been used with the AR88 if indeed it was ever used with a transmitter in military service.

Re: R1556A/AR88 transmitter
Thanks for the replies. I was just curious as there is provision for receiver muting. If there was no 'companion' transmitter, I guess a 'period' transmitter of the time would be something like a BC459A or the monster T1509 for which I would not have room even if I could find one!.

Re: R1556A/AR88 transmitter
Interesting AR88 question. Re the info from Stockden, I've said before that mine has a "slave 36 " badge so perhaps it was once a part of a Y Group monitoring stack? There is very little ref anywhere to an associated TX, you are right. Even Wireless For The Warrior and the VMARS site just write it up as a high quality set.
An amateur [mentor] I knew in the sixties was very proud of his set, using it with a Heathkit DX100. He explained the T/R switching system in the RX to me but no mention of a war time use. Clearly it must have been originally designed with some sort of "Ham" radio TX in mind but that doesn't necessarily mean they were ever paired up with a TX in conflict I suppose! Curious though. I suppose members of the VMARS group might know something? Dave W |
