[Elecraft] K3-100 low power output

[GRANT YOUNGMAN]

Check the SWR into the amp.   I have a couple of bands where the input tuning circuits have drifted a bit on my AL-1200.  I need to get in there and retune my amp, but the simple solution in the meantime is to use the auto tuner in the K3 to take care of it.
