[Elecraft] K1 won't transmit on band 2

Pete,

Can you receive a signal that is known to be on 20 meters?
That is an important first step.  It is possible to mis-tune the 
Pre-Mixer bandpass filter so that the K1 can receive signals, but they 
may not be in the 20 meter band.
If that happens, then the transmit signal will not get through the Low 
Pass Filter which has a cutoff frequency just above the 20 meter band.

If you have another transmitter capable of producing a 20 meter signal, 
feed it into a dummy load and put a "hunk of wire" antenna on the K1 and 
place that antenna near the dummy load to pick up the signal.

73,
