[Elecraft] CW pitch changes slightly between filters...

[Don Wilhelm]

Steve,

Due to the DAC resolution, up to a 20 Hz shift can be expected.  For CW, 
it is usually not a problem (just a bit of a surprise when you first 
notice it), but for digital modes it can cause the stations in QSO to 
'walk up the band' if you do not take countermeasures - locking the 
transmit frequency in the software application is usually the best 
preventive measure, you may have to retune the receive end in the 
software, but the operator on the other end should not notice any change 
if you have locked the transmit frequency.

73,
