[Elecraft] [K3] Wide CW RX issue in 2.32 firmware

[Leigh L. Klotz, Jr WA5ZNU]

With 2.32, CW mode doesn't seem to have the correct bandwidth above 
1KHz, which is my 2nd-widest filter.
LSB mode provides good bandwidth at 2.8Khz, but in CW mode, it doesn't 
offer that same result at 2.8Khz.
I thought perhaps the issue was the center frequency of 600Hz vs 1.5Khz, 
and perhaps it is, but when I shift the CW center frequency, I don't get 
any more bandwidth.  Furthermore, the audio sounds markedly different 
when I veer off of 600Hz center by even 50Hz, as if it's selecting a 
different  xtal filter or something.

If this isn't "as designed" and you can't reproduce this please let me 
know and I'll provide .wav file recordings for you to examine on a 
spectrum scope.
