[Elecraft] [K2] Low Output Power solved

Turned on my K2 after about 4 months of not being used. No evident output power! The rig has worked well without issues for several years since I built it. Checked with dummy load and was actually putting out about 200mW. Searching archives, found similar problem mentioned with Don

[Elecraft] K2 Low output Power

OK, I confess that after building control and receiver circuits [carefully] with no problems, I wanted to believe the rig was 100% after initial transmitter alignment. I put the rig on the air and made contact immediately. THEN: a friend loaned me his OHR WM-1 wattmeter so I could
