[Elecraft] K3/100 TX problem on 20m

[Paul Kent]

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.

Paul, K0PK
