Implementing that for the XV144 could supposedly be as easy as lifting
the end of C15 which connects to Q1 and injecting the 116 MHz signal at
the 'flying lead' of C15.

Another aftermarket solution might be the new DIGILO PLL synth from DEMI
for $99:

It can use an internal TCXO or high stability 10-MHz ext reference.
Basically disable the current LO ckt and capacitively couple 116 MHz RF
into the XV144 in place of xtal LO.
This unit replaces the A32 PLL which apparently is NLA. I run them in
my 432, 1296, 3400, and 10-GHz transverters.
