[Elecraft] K2: Sudden CW filter FLT2~FLT4 shift!!

[Don Wilhelm]

Dave,

The ST P parameter changes only the sidetone pitch, it does not change 
the filter centering.
BUT, the amount of transmit shift is determined by the ST P value, so 
the transmit frequency will change, but the receive frequency stays the 
same.  That is why it is best to center your CW filters at the same 
pitch as your sidetone.
