K2 CW FIL2 problem

Donald Currier
Hi Guys,

I've recently developed a problem in #5885. If I select XFIL2 in CW  
mode, the signal becomes very muffled, and unclear.

I used spectrogram to check my filter setup, and the signal doesn't  
look clean in spectrogram either.

Only XFIL2 in CW is affected. CW reversed is fine, and the SSB  
filters seem fine as well.

Listening to WWV, the signal strength on the S-meter goes from 20  
over 9, to S-1.

Any help as to what might be the cause?

Thanks!

Don

Don,

About the only thing I can think of is that you may have the FL2 CW filter
positioned on the wrong sideband.  Spectrogram will not tell you that.
Look at the frequency display while in CAL FIL.  The frequency of the FL2 CW
bfo should be within a couple hunderd Hz of the frequencies set for the
other filters - if it is a kHz or so away, then you have it set to the wrong
sideband.
