Hi all,

Just for the record:

K3 #1255:
for main RX:
BW: 2.7k  - 2.1k  - 400 - 200
gain:  0     -   4     -   6    -  8      dB

Sub RX:
BW: 2.7k  - 2.1k  - 400
gain:  0     -   3     -   6     dB

Measured with XG2 on 50 uV, AGC-off -  dBV indicator of K3
With above settings, output is nearly constant.

If there is still too much deviation, think about the following solution:
Make sure your SSB filters are gain-matched as a group, and do the same 
for the CW filters.
Ofcourse this will depend on the filtercombination in your K3 and the 
filters you use for different modes.
