I have started this on my ~40 year old Tristar 747.
Rather than get really invasive, I have programmed a little Arduino/si5375 box that sits on top and replace the PA socket with sma to feed the output of that box to replace the "LO" cristal on the crystal PCB. I thought about taking a feed from the LSB line ( 3kHZ offset ) but just have a "mode" indicator on the external box.
This potentially gives me 26-30 depending on tunning / lock range.
Is it worth it? - probably not but its great fun :-)
Dire warnings about some about phase noise if not using integers on the si board seem overblown.
