Another PC122XL TX Problem

Not to be captain oblivious here but...

Make sure you have the right Mic wire to the right spot...

Last minute detail - kinda' thing.

Regards!
 
Andy I was thinking the same thing this afternoon. If the ground and audio were somehow swapped I was thinking it would have the same effect. I think.
 
Ground thru a 600 ohm might - because speaker is done differently - what normally would use 1 - 4 on the mic socket is toggled internally thru a diode on the main board (that D38 and CB PA switch in CB) - but if the mic wires to the radio were reversed ... hmmm...

    I will not be there but hopefully by the end of this month I will have my New tower and antennas back in the air including my M2 6M5X. The old tower and all of my antennas came down in October 2023 during a Hurricane.
