[Milsurplus] HC6U crystals needed 7.007/5.535

[B. Smith]

Ray you probably need to off set for the audio. Put a good "calibrated" 
receiver on
5690(dial frequency), transmitt on the PRX-108  and see what the actual 
crystal frequency in the PRC-108 is  to generate that signal is.

Picked up a couple AN/PRC-108 transceivers at a fest the other day, only 
two that I have ever seen before with the exception of Mr. Starks, 
anyway if your like anyone else and unfamiliar with them they are a 
solid state AM/SSB portable transceiver that was built for the Coast 
Guard by Sunair back in the late sixties or early seventies. Big radio 
for portable operations but way open and easy to work on, they both have 
crystals for 2.182, 2.638, 2.670 and 5.690 so the plan is to change 
channel 4, 5.690(USB) to 5.357(USB) and channel 3, 2.670 (AM) to 3.885 
(AM). Looking at the manual that’s available on line on Sunaisrs site 
don’t think this will be a big deal but it creates one of the largest 
problems today with radios of this age, I will need two HC6U crystals. 
One on 7.007 MHz for 5.357 to use on M&S net and a 5.535 rock for 3.885 
AM at other events. The radio use the same crystal for TX and RX with a 
1.650 offset, so if you have one or two of these rocks please contact me 
and will see what form of a deal we can work out. Ray F
