I am having trouble with biasing of the driver and final. I can’t turn driver down below about 75 ma.and then it drifts about to about 95 ma when keyed . And I can get the final down to about 75-80 at the lowest but then as I hold down the key, it will slowly drift higher to well over 100...
Saw pics on another site about how to do the Channel expand on this radio. Here are pics from inside my radio. Can someone confirm this is the right part to remove? Looks like it is the one with the white arrow on the board (which is already on the board-kind of weird?). Thanks !
