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
