[ARC5] AN/GRC-109 serial number

[Fuqua, William]

   I had seen your article. I have some HG-10B VFO's.  I was thinking of making something in a GRC-109 case to sort of match the rest of the rig.

Hi Bill - I have had good luck driving the GRC-109 TX with an old Heathkit HG-10 VFO.  No mods to the transmitter or VFO, the combination produces full output, no chirp..
Take a look here for details: http://www.n6cc.com/angrc-109-rs-1-transmitter-with-vfo<https://na01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.n6cc.com%2Fangrc-109-rs-1-transmitter-with-vfo&data=02%7C01%7Cwlfuqu00%40uky.edu%7C495aa2f357de4a979c4108d67feecf26%7C2b30530b69b64457b818481cb53d42ae%7C0%7C0%7C636837060988752148&sdata=ya0Wrw7VxCMkWrrQXcN0DogvtbKm6R64iR5BQxiD3%2BI%3D&reserved=0>

Just need to keep the VFO-TX coax wire short to reduce the shunt capacitance.

Matching serial numbers are always nice - but somewhat rare in my experience.  These sets saw lots of use over a long time period and "stuff happens" to mix up components.  Part of the sets "charm" really...

Anyway, give it a try...

Our radio club has an AN/GRC-109 transmitter with a different serial number on the transmitter panel than on the cover. I am putting it up for sale at some point and wonder if the serial number mismatch affects the value. And if so if blank cover plates are available somewhere.

 I noticed that it will produce almost 20 Watts into a dummy load on all frequency ranges.

I personally have a set that I am keeping, and wonder if anyone has any ideas of a VFO  that could be used with it that is a good match. Have a junk TX that I could build a VFO into that would match the set.

 Or I could build one into a one of the high speed keyer boxes. Empty boxes are available on the surplus market.

It should probably be a tube VFO however, I could possibly build a solid state one.

   Just brainstorming here, any ideas?
