[Elecraft] Low outout power on higher bands, K2

You may wish to check the power supply current drawn for the maximum
output power on each band, If it decreases when you select the higher
frequency bands there probably is a RF drive level problem.

If the current is high on the higher frequency bands then you have a
problem with the output impedance matching filters etc as you stated.

How are you measuring the RF output power ?

On my K2 with the KAT-2 Bypassed I get only 8W out on 10M @13.8V the
KAT-2 has some insertion loss. The lower bands are at least 10W or above
