[Elecraft] Filter Setup Questions

[Fred Jensen]

I'm setting up my K2/100 for RTTY, using a RigBlaster and MixW.  I 
recently had an unrelated KPA100 problem, and Gary fixed it for me, and 
also totally aligned the radio [thanks Gary, that service was totally 
worth it, my K2 is way better than I thought, and I was pretty impressed 
before!].  I don't want to change anything he did, it's really perfect, 
except I want to adjust the BW of one of the SSB filters a little.  Can 
I just adjust the BW in CAL FIL for that filter, and not mess with the 
BFO settings?    I just want to make it a little wider and I really 
don't want to undo what Gary did with everything else.

Second, are the USB and LSB filters locked together ... i.e. if I change 
the BW on USB, have I also changed the BW on LSB?

Third, if my mark-space are normal below 15m, will they be inverted on 
15m and above?

I just barely understand the K2 filter things, and sometimes I have QSB 
in my mind.  This is one of those times.  (OK, maybe I don't 
"understand" the K2 filter things like I said).
