Based on the KX3 specifications, it is designed to run at lower power for full-carrier modes.
From the transmitter specifications on page 54 of the KX3 Owner’s Manual: "5 W or less recommended for high-duty-cycle modes (FM, AM, DATA). Power will automatically be reduced if PA temperature or current limits are exceeded.” I’d check the KX2 specs for info on that model. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Mar 18, 2019, at 1:55 PM, Bill Frantz <fra...@pwpconsult.com> wrote: > > Based on a presentation by Eric at the West Valley Amateur Radio Association, > Elecraft tends to build their equipment to run at full advertised power with > digital modes.
