[Elecraft] [K2] question about crystal filters and DSP audio filter settings

[Robert G Strickland]

Kevin...

Don's advice is excellent and reflects his many-faceted expertise with 
the K2. He repaired mine a while ago after I had reached the end of my 
line with the unit, and his advice here is always spot on.

I would offer a comment on Don's very last bit that less than 200 Hz is 
seldom necessary. Generally true. I have found that, when the QRN is 
high, either natural or human generated, bandwidths down to the K3's 50 
Hz DSP limit can sometimes be useful, even allowing for lost gain and 
the ringing and signal artifacts. Just a thought.
