[MRCA] Transmitter to pair with a AN/GRR-5 Receiver

[Ray Fantini]

Would assume that a T-195/GRC would net with the receiver but more inclined to think maybe a GRC-26 would be used to broadcast out to those receivers with something like a T-368.  The popular thought is that was intended as a network warning receiver and used for things like general broadcast orders, air and gas warnings. Going to assume that they would have been set to monitor a large broadcast type transmitter located at a safe operational distance  away. The broadcasting transmitter may have been something like a commercial 1 or 5 kW transmitter feeding a full size antenna system but that’s just pure speculation on my part.
Have spoken with people who have clamed to have used them in the field but never as a tactical radio.
I do know that the military did purchase a number of RCA broadcast transmitters that would have been more then up to doing that job, although always thought that was just for Moral and Welfare.
If anyone knows how GRR-5 was intended to be used and what the originating station consisted of that would be interesting. One thing for certain is that looking at the huge numbers of GRR-5 receivers that were produced they must have had some determined roll.

There is arguably nothing organic nor period that would go with that receiver.  That said, there are a myraid of commercial, 100 watt class transmitters that would be operationally satisfactory (e.g.: Ranger, Challenger, WRL, etc.).  ARC-5/274-N would work but not are not related.  Maybe an ART-13 or a T-195/GRC-19?  Any of these would make a strange combination, however.  So, it comes down to simply select something and integrate them (muting, antenna xfer, etc.

Anybody got any ideas as to what transmitter might pair well with a AN/GRR-5 Receiver?  I know this receiver was designed and  issued as a stand alone and did not have a designated transmitter specifically paired to it. A local owner is asking this question (not me), and I don't really have an answer for this, other than maybe a BC-610, and that transmitter is way too large and rare for him to either find or use.
