[Elecraft] K2 - IF shift

[Ron D'Eau Claire]

If you want a narrower passband, just use one of the CW filters instead of
OPT1. 

But with the SSB filter already down near the minimum passband  for decent
voice quality, I only find that useful for digital modes. 

Remember, as Don pointed out, FL1 is always used for transmit, no matter
which filter is being used for receive, so it must be set up using OPT1 and
adjusted properly for transmit. Then you can do whatever you want with Fl2,
3 and 4 to provide optional bandwidths and changes in the pass-band for
reception.

As Don pointed out, the IF passband can be shifted lower or higher (but not
narrower) using the SSB filter on the KSB2.
