Came home and fired the rig up. let it run for an hour. Found a 10 to 15 W carrier on Both side bands.
Attempted to NULL the carrier.? The POT works and did null it down to 3W.?
The Trimmer Cap only has an effect of maybe .5w.? ?
I clipped a counter to the test point of the carrier xtals and could not believe it. Both xtals had moved in the right direction!? ?
What the heck.? They are both spot on now.? 1648.550. I can adjust up and down from there. That xtal was best case 1648.4?
I guess the trimmer failed???? ?
I hate to have to change it. its riveted in.? I have a replacement 5 to 25PF trimmer.? Also new modern diodes. I guess I will rebuild this circuit now.
