Vehicle Mounted PRC-77 Sets

[Mike Cecil]

I've checked the inventory lists for the following:

AN/PRC-77
AN/VRC-64
AN/GRC-160, all three of which use the RT841/PRC77 receiver-transmitter, and none include a canvas cover.

I've also checked the inventory lists for the following:

AN/VRC46
AN/VRC47
AN/VRC48
AN/VRC49, all of which use the RT524/VRC as the receiver-transmitter, and none include a canvas cover.

So if canvas covers are/were available in Canada, I would suggest these were supplied from local production to satisfy a local (ie Canadian) requirement. Neither the US listing nor the Aust listing includes a 'covers, canvas' of any description.

If a unit indented for any of the the US sets mentioned above that are prefixed with the 'AN' end-item indicator, a complete set-up would have arrived in the nice cardboard crate. However, just indenting for an 'RT/524' or an 'RT841/PRC77', would result in just the transmitter-receiver arriving, and not the complete set-up with cables, hand mics, antenna, and so on.

The AN/VIC-1 control harness is not a radio or part thereof. It is the intercommunications system within the vehicle to allow communications between all members of the vehicle crew (and an external infantry telephone on the vehicle exterior). The 'heart' of the system was the AM/1780/VRC audio frequency amplifier. Any of the above GRC or VRC sets could be linked into the AN/VIC-1 harness through the AM/1780/VRC to allow the crew to communicate by radio transmission beyond the vehicle.
