[Elecraft] IMD of MOSFETs vs. bipolar

[Lou Laderman]

It’s only anecdotal, but I was in a 6M QSO where we both were receiving each other with 20dB+ signals. I adjusted CMP from 0 to 30 and the difference heard by the other station was 6dB. It definitely works.

Reducing power while maintaining communications effectiveness recently became a whole lot easier on the K4 with the addition of CESSB. In our tests, average power went up by over 6 dB between settings of CMP=0 and CMP=30.
