I’m looking for a “service manual” not the owners manual for the 5054dx non 100 version. I’ve acquired one real cheap on eBay in mint condition and it works “pretty good” but has a few minor quirks that need some straightening out. It needs an alignment on the pll carrier oscillator cans because for example if you want to talk on 50.200 usb you have to set the vfo to 50.199.8 to be right on with the station you’re communicating with. It needs a receiver alignment that I can do without the service paperwork, but I need the pll and transmitter alignment procedures so I can properly set the frequencies on the carrier oscillator cans. I do know how to do the modification to make the clarifier/RIT control transmit and receive track together but that still don’t do me any good when i don’t have the alignment procedures from a service manual. I’ve looked all over the place for documentation on this unit. Google, mods.dk, cbtricks.com I’ve even contacted radio shop supply.com and got nothing. The only thing left is to try and contact the manufacturer but I doubt that will do me any good.
