My beloved Yaesu FT-1000MP (the plain version, not a MkV or Field version) has suddenly developed a problem. The faceplate momentary contact "button" that transfers the VFO-A signal to VFO-B does not operate when I push it in. The button next to it that alternates the frequency from VFO-A to VFO-B and vice versa works fine. I do not hear a relay "click" then I push the VFO-A to VFO-B button like I do with the VFO-A alternating VFO-B button on the faceplate. I've done a factory reset a few times, inspected the radio's chassis, wiring, circuit boards and all looks fine. No smoke, crackles, sizzles, etc. I'm far from a repair expert regarding issue like this and would appreciate any help offered. Tnx, 73, Bill / w0bp
