CW audio

Dennis Watkins

I can't seem to get the audio on CW to be like it is on SSB.  With
only one filter I would think that switching between CW-SSB the
band width should be the same. It isn't and I don't know why.  If
I hit the "XFIL" button it is the same.  It sounds like I'm band
limited to about 1.5kc.   The internal filter is stock 2.7kc. Radio
#3109, K3.

Re: CW audio

I believe this is caused by the shift in the IF's center frequency when
switching to CW. You can vary the shift with the "Shift" knob to change the
sound. If you are in SSB mode and set your shift for an FC of 600 or
whatever your cw FC is set for, it will sound just like you are in cw mode.
Keep in mind however that if you change the shift in cw mode it will affect
your ability to use narrow filtering. I usually just leave my shift at the
default as indicated by the *. Note that changing the Pitch will change the
shift FC.
