[Elecraft] K2 - No power control on SSB
I have K2 ser# 5614. I am unable to change power on SSB, full power out. Works in CW and tune, same problem with or without ATU. in TX: U1-2 .5v U5.5 .5v U1, Q1 and Q2 have been replaced. Any idea where I should look next? Ben NE5W ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.
