[Elecraft] (K3) Low power on some bands

[Don Wilhelm]

Jan,

Run the TX Gain Calibration.  You may have to borrow a dummy load that 
has a lower SWR if the calibration procedure shows errors.
K3 Utility makes it easy and automatic, but it can be done manually - 
see the Calibration section of the manual.
