[Elecraft] K3 Filter question

[Keith Heimbold]

Matt,

Thanks, I was hoping that was the case. The 1.8 kHz filter is good for SSB but not exactly what I want at 350 kHz in CW. I think I will set it for 600 kHz and see what happens.

I really appreciate your quick response.

It generally cuts out at 300 kHz and then my 1.8 kHz filter takes over. I would like to use the 250 kHz filter up to 400 kHz as I have read the filter is actually specified for 370 kHz. How do i change the cut out point for this filter? Is this something I can change in the utility program under filter calibration? I appreciate any advice on this.
