[MRCA] Regency Radio Pallet

Thu May 28 21:55:49 EDT 2020

From what I’ve been able to find so far, NOBODY has been specifically authorized by any government entity to use any frequency in the 33.5 to 38. 0 MHz am range ( VHF-AM ). VHF -AM  from 118 MHz to 136 MHz AM is used by aviation, but the Torn Fu.2 isn’t capable of operating in that range. The other VHF Band (VHF-low and VHF- high) are fm. So are we talking about some frequency range (33.5 to 38.0 MHz am )that’s basically the Wild- Wild West ?  Knowing how politicians and government administrators would like to control every aspect of just about anything they can think of, I would find it somewhat difficult to believe that somehow some government bean counting weenie hasn’t slapped some sort of control over frequencies in the 33.8 to 38.0 MHz am range.

>> My next project is a German Torn Fu.d2 transceiver - not a repro, a real one. The transceiver itself has been modified. 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.

>>      The original cabinet for this radio is very interesting. It’s made from a laminate.  Wood sandwiched between two thin layers of aluminum. The radio I have was made in 1944. 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.

>> Ok, so am seriously planning on starting on a new long term project. This would be restoring and setting up a AN/GRC-215 Regency Network radio pallet. 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?
