Roy: I assume you are probably making these measurements/observations on CW, in which case I can't add to what has already been suggested.
However, if you are testing in SSB mode, there is another possibility. Some K2/100's have trouble keeping the power down on SSB, especially on 80m. The ALC action is just not aggressive enough in these units....they probably have a bit higher gain through the transmit chain than most, resulting from particularly "hot" transistors, etc. This is particularly obvious near the 10 W crossover between the QRP final and the KPA100. If I recall correctly, mine gives about twice the output at the 11 watt setting as it does at the 10 watt setting, even after a mod to make the ALC more aggressive (which is adequate to stop more serious over-power/distortion problems at higher power settings). To check look at the K2 output power display; if you see 30 watts peak on SSB on the display then you may actually be getting around 30 watts rather than the 12 watts you have it set for. This problem does not affect CW however; the actual/displayed power output should be very close to the requested value. 73, Steve VE3SMA __________________________________________________ Do You Yahoo!?
