[Elecraft] K1 stopped working on 15m and 20m

[Don Wilhelm]

John,

If you cannot find a signal generator, do you (or a friend) have a 
transmitter that can produce a signal on 15 meters?  If so (that is a 
signal generator), run it into a dummy load and connect a wire "antenna" 
to the K1 placed near enough to the dummy load to produce a signal that 
you can hear.
Adjust the 15 meter bandpass filters for maximum response on receive, 
and then further refine that adjustment using the K1 transmit, peaking 
for maximum power (set the menu OUT parameter for 1.5 watts and exit 
TUNE and reenter TUNE if the actual power exceeds 4 watts).
Once you have 15 meters working, then adjust the 20 meter bandpass.

73,
