[Elecraft] Problems because of filter switch during CW operation K2

[Steven Pituch]

Dear Martin,

If your narrow filters are aligned using the Spectrogram software so 
that they are all centered on your cw tone (say 600 Hz), then all you 
need is to zero beat the signal while in the 1.5 kHz filter, and then it 
will stay centered even at 100 Hz.  The instructions for finding and 
using Spectrogram are on the Elecraft site.

For a lesson on zero beating see:
