![]() Place the tranceiver upside down and remove the four screws from the bottom corners and two on either side (including the carrying handle screws). Remove the two screws at the front of the top cover (heatsink). Remove the two screws affixing each VHF or UHF band module and slide the modules out of the tranceiver. Switch off the tranceiver and remove the AC power cable and all other cables from the rear panel. The radio can now transmit from 1.5 Mhz to 29.999 Mhz The board we want has some switches on it,(one of them allows 5 Khz/rev or 10 Khz/rev tuning), locate S 01 and flip the switch. Lift the loose card tray to expose the inner circuit boards,there are two wires that need to be disconnected to do this (dont forget to reconnect them!). Remove the bottom covers,plastic rear panel then the metal rear panel,loosen the hinge screws on the front bottom. Once you open the radio back up with the knobs toward you looking down into the radio the switch should be in the position to the back of the radio, that is the "General Coverage" position. I would say that the ham operator that you got the radio from knew you were planning to flip the switch and disconnected it, check that out first. ![]() Any help from the experts would be most appreciated in solving this mystery. What am I missing here? Mods from different sources read the same. Worked great on the ham bands but not on any CB channels. ![]() Thinking the mod had been done before I got it, I took the radio apart again and returned the switch to the original position. Trying the Ham band frequencies the radio puts out about 130 Watts USB and LSB. Post mod found the internal tuner does its job like it should but no output on any CB frequency. Once done the mod says it will xmit from 1.5 to 30 MHZ which is just what I need for 27.385 lower side band. This switch has only two positions so doing the mod was easy. ![]() The mod requires a complete disassembly of the radio just to get to switch S01, a slide switch, and move it to the next position. ![]() I performed the mod to convert it to all band receive and XMIT. I acquired a mint condition Yeasu FT-767GX with CAT system. I thought I would run this one by the experts. ![]()
