Here is what I posted on the Yahoo group just now. I hope a little time
helped clarify my description....

I can better explain and reproduce the issue now. Thanks to Dale WA8SRA,
Don W3FPR , and Wayne N6KR for hints along the way
I have the following 8-pole filters
Main: 1=15k, 2=6k, 3=2.8k, 4=2.1k, 5=0.4k
Sub: 1=0.0, 2=0.0, 3=2.8k, 4=2.1k, 5=0.4k
I am tuned to 10.000 MHz USB in diversity mode with Lo = 0.00 and Hi = 3.0
I observe RX A XFIL = FL2 (6 kHz) and using BSET I see that RX B XFIL = FL3
(2.8 kHz)
At this time RX A passband starts at 10.000 MHz but RX B passband is shifted
-1.5 kHz to start at 9.9985 MHz
Now I decrease Hi to 2.8 kHz.
The instant I do this, RX A XFIL shifts from FL2 (6 kHz) to FL3 (2.8 kHz)
and RX A and RX B passband are both aligned properly to start at 10.000 MHz
I can work around this.
Cheers
