Don, Thanks as always for your reply.
But you don't seriously believe that my problems with electronic equipment could be THAT simple, do you?? After all, I'm the guy whose dog ate one of the ICs while I was building the K2 (no joke). I ran 5 watts and 2.5 watts, and ran each test five times (first 5, then 2.5, then 5, then 2.5, etc.). With 5 watts commanded, both power meters usually read about 12 watts, the K2's RF display read 5, and both the K2's ammeter and an external WattsUp meter read about 2.7 amps. HOWEVER, on one try, both power meters were indicating 15 watts (with about 2.8 amps on the ammeters and 7 on the RF display). With 2.5 watts commanded, the MFJ consistently read 7 watts, and the W1 consistently read between 6 and 8 (it doesn't have a display for 7). The K2's RF display flickered between 2 and 3, and both the K2's ammeter and the WattsUp read about 2.1 amps. You had me run this test sometime late last year because I was reporting excessive heat when running in digital modes (e.g., PSK31). At that time, the numbers were a lot closer to what was being commanded -- although back then I was running it with the KPA100 in use (trying 100 watts, 50 watts, and 25 watts). This started today because I was trying to tuck up the ribbon cable and the speaker wire, which you had suggested to me a while back. I hadn't actually tried that until today, and I noticed the power and SWR problems after I buttoned everything back up and was testing the change. I've put the ribbon cable and the speaker wire back where they were to begin with, but am still having the power and SWR problems, so my guess is that I managed to mess something up while I had the case open, but I don't see anything offhand when looking at it now.
