Menu Switch Not Working
The menu switch is much worse. It is still intermittent, but mostly not
working. I checked the circuit connections from the Menu button to U3 pin 6
(/BANK 1) and to U2 pin 6 (D7). All checked fine and I also checked
connections at RP1, again fine.
The XIT button works, all the other front panel switches seem to work OK,
so does the RIT switch.
I had an Electrical Engineer friend who is a ham go over this all with me
this afternoon and he concurred that all seems as it should be, and at one
time the menu switch worked, but all the rest of the time no effect.
We connected the two appropriate poles of the switch, still no action on
the circuit.
Reheated all the pins on U2 and U3
I performed a hard reset by holding down the 4,5, 6 buttons at the same
time when the power is turned on and no effect on the menu switch.
Is it possible that I have a bad U2 or U3? I do not know what else to check
suggestions?
