You might want to try a CPU reset.
You might have to do it a few times.
You will have to re-program the radio
after.
Good luck, 73
By the way. If you ever have to tighten the volume / squelch
knobs, DON'T!! Those switches are mounted VERY poorly
and you will rip the control off the circuit board. This might be not
fixable!!
Took me 4 HOURS to repair it with wire wrap wire. Any other wire is
WAY too big. This is truly micro surgery!!!
The only way to tighten the knob is to take the front panel apart
and hold the back of the pot so it won't rip off the board.
SHAME ON YAESU!!!!!!!!!!!!!!!!!
