[Elecraft] P3, what lies ahead?

[Don Wilhelm]

  If you are using a filter width that is greater than about 1.5 times 
your sidetone pitch, the filter must not be centered at your CW pitch - 
it must be skewed so that you do not receive the opposite sideband.
That offset is done automatically in the K3.
