[Elecraft] Power output keeps folding back to 5 watts on my KX2

[Walter Underwood]

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.

Their model is a RTTY contester calling CQ with 60% to 70% of the time transmitting. He indicated that the KPA1500 would run for 5 minutes at full output before needing a rest.
