All is working now...had to drop the front panel and visually confirm pin engagement due to a warped chassis.
My Drake TR-7 is now doing the same thing. I was having a problem with the display on 10 meters and was told to ensure all the boards were snug. I did, then rechecked them a 2nd time but this time I pulled the boards and cleaned the sockets and pins. After reinstalling everything and turning the rig on, my display is now reading 51950 but I can still copy signals on all the bands. What exactly did you find that cured your problem?
