Re: [Elecraft] K3/100 TX problem on 20m

Hi Paul, I'd say that our respective KPA3A TX Gain calibration values are similar enough. Having not had the bipolar PA model KPA3, I don't have a point of reference for whether your TX gain parameter values are reasonable or not. I would contact Elecraft Support and copy Keith, WE6R with a
