[MRCA] J22/ARC-5 throat mic push to talk switch question

[Robert Downs]

I don't totally agree with the below statement.  If the HF pair were an R-26 and a T-19 tuned to 3885, that would often be usable.  And the R-28 and one or two of the 4 channels in the T-23 will tune up on 2 Meters.  Of course, the set is AM, not FM.  But there might be a way around that.  The only thing that I can't think of any use for would be the R-4.

The historically-accurate representation of a typical three-receiver two-transmitter AN/ARC-5 radio set in a late war carrier-based single-seat fighter such as an F6F-5 would be unusable for most ham activities.
 
The three receivers would be:
R-4A/ARR-2 VHF ZB homing
R-26 or R-27/ARC-5 HF locked-tuned
R-28/ARC-5 VHF four-channel
These are controlled by C-38/ARC-5 with VHF channel selection by C-30A/ARC-5.
 
The two transmitters would be:
T-19, T-20, T-21, or T-22/ARC-5 HF locked-tuned
T-23 or T-126/ARC-5 VHF four-channel
These are controlled by C-30A/ARC-5 in VOICE mode.
 
This maked a very compact and capable set that provides one HF channel and four VHF channels for VOICE communications plus a ZB-homing receiver with six pilot-selectable MF modulation channels.  (This is the AN/ARC-5 and AN/ARR-2 configuration that I have assembled.)
