Thanks again, Mike. My K3 has the bipolar 100w PA.
I also have a properly-functioning K3S/100 with the CMOS PA. Just for comparison I ran the HP TX gain calibration on the K3S and it produced these numbers: 160m/19 80m/08 60m/10 40m/12 30m/13 20m/08 17m/08 15m/05 12m/10 10m/10 6m/06 The numbers are significantly different from those of the K3 but that probably doesn’t mean much. I even thought about swapping the PA modules between the K3 and K3S as a test but they are not compatible for a direct swap.
