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. 73, Lou W0FK On Jun 28, 2022, at 11:18 PM, Wayne Burdick wrote: Reducing power while

I meant to point out another fact about the way the K4 handles power control. In addition to the usual ALC and our very clean CESSB-based compression, the K4 limits maximum drive in AF modes (audio-derived data and voice). This limit is calculated on a per-band basis, ensuring an upper bound on
