Gary pointed me to: http://www.elecraft.com/Apps/Power_Control_Mod.html
and also said, "...there is an optimum value of R98 for any specific K2 that will allow the best power control resolution. Basically, it allows the 8 bit DAC (U8 on the control board) to use more of its maximum possible 256 bits of control." This is cool! Tweakage for my specific rig...The closest I had was a 5K pot, and I fiddled with it a bit, but couldn't get a truly satisfactory result with 10W on 10M, because, I think, my dummy load is only for 5W. I finally went to 40M, and tested to see the highest value that would give me near what I requested as power-out, but since the suggested value of the pot was 1K, I didn't exceed that. I wound up replacing the 270 ohm R98 with a 1K, and now I'm well-pleased; getting just a few tenths of a watt over the requested power level on all bands.
