Re: Many uBitx's have reduced power on 40m CW

Jerry,

I agree with your assessment.  I really need to do the IMD and power tests for SSB.

Doing some more simulation, I do believe that increasing R83 to allow for a better filter impedance match is probably a good thing.  The 10 ohms with 1nF C81 seems to be the best but does reduce the total output. 

Thank you again for the input.
