Here's the mods I have... but I still don't know where D54 (Out-of-band TX
for VHF & UHF) and D61 (out-of-band TX for 50mhz) are...
Anybody know where to look on the boards?

Remove D54 on the LOGIC boards expand VHF and UHF bands
137-229 mhz high band
350-500 mhz uhf band
(where the heck is D54?)
Remove D61 on the LOGIC board to expand 50 MHz band
50-65 mhz low band
(where the heck is D61?)
