[MRCA] Regency Radio Pallet

Thu May 28 19:45:25 EDT 2020

Torn Fu.d2 should be able to operate with the low band side of the PRC-25/77 provided the squelch is left open on the more modern radios. But the frequencies are on a band reserved for government use.

Coax cable connector for the antenna ( original was a banana plug ) a push button for something where the plug for the telephone remote was, and some vent holes drilled in the transmitter case. I have a 2nd transmitter case that, with a little work, can become the battery case.  The calibration device that is mounted in the battery box used a “magic eye” tube to set calibration.  Also got a line on somebody who makes really good reproduction parts. The goal is a correct, fully functioning  transceiver.

I’ve managed to get a clear copy of the operators manual ( in German, of course ) and I’m already gathering accessories ( like antenna base, microphone, headphones, power plug and Morse code key ). I also was able to get an original transmitter front cover that, while it’s not restorable, I can pull parts off the lid and have a new lid made.   This radio operates on the lower end of 80 meters.

This would include a GRC-215 transceiver, power amplifier, reference assembly and digital control unit. No, I don’t have and will not be looking for the TSEC KG-84 or the KY-65A security equipment but fortunately they include a bypass box on the pallet that allows you to use it without the security equipment installed.
> The problem I see right now is according to the manual the digital I/O control system, they call it the D/K assembly looks at the reference oscillator assembly (RFO) and wants to load TOD (Time of Day) data when the system starts and without a valid TOD entry the system is in fault.
> Been thru the book a couple times now and it looks like you had to use a key loader like a KYK-13 or maybe a MX-18290 to load the TOD data. They also have a GPS port on the reference assembly but cannot imagine that it would be as easy as just providing NEMA data at that port. Anyone got any ideas?
> So far this is a hypothetical project, got a line on the pallet with most of the hardware and now may be in a place where I can get the radio itself so I am trying to see how much more would be involved with this.
> Also posted this to the GRC-215 group, who would have thought! Have to wonder if they have a GRC-106 user’s group?
