[Elecraft] K2 scratchy noise on RX CW signals

[Don Wilhelm]

Andrew,

That sounds like you had the NB and/or NR set on in the KDSP2 with 
aggressive settings.
If the settings were aggressive, it would give you 'scratchy' audio - 
but it does eliminate other unwanted signal sounds.  You might want to 
put the KDSP2 in again and try several settings - see the KDSP2 manual.  
Start with all settings at default and go from there.
