Gang,
The URC-14 seems ready for serious testing at Gilbert on the official
MRCA 2-meter frequency. The PRC-117D will be there to provide backup on
VHF AM.
I'd like to thanks Zorro, K4CHE, for his advice and encouragement.
For anyone considering a similar project, I can recommend International
Crystal Manufacturing for custom crystals. They are easy to deal with
and prompt. All it took was money, $28.34 in this case. The important
missing parameter for the 72.125 MHz 5th overtone crystal was that it
needs to be specified as "series resonant." Also, it was necessary to
remove one turn from each of the four coils in the radio to move up from
the original 121.5 MHz. This was not difficult.
YMMV,
Al
