CW Pitch

I only completed my new K3 (complete with subreceiver) a couple of days
ago, and it's my first experience with true dual receive with stereo
headphones. I suppose that with time and practice I'll become more
proficient at copying different signals in each ear, but at present I
find it easier to do so if the CW pitch in one ear is different than in
the other ear. With a really narrow bandwidth (say 250 HZ roofing and
200 Hz DSP), though, there isn't much room for a shift in tone before
the desired signal starts sliding down the skirt. Is there any way to
set the CW pitch separately for the main receiver and the subreceiver?
I've searched both the manual and the reflector archives and haven't
found any mention of separate pitch at all, either yes or no.

Thanks much es 73,
Dave AB7E

Re: CW Pitch

Hi, Dave,

If what you are saying is that you want to hear a different band of tone in
each ear, say 400-550 in the left ear and 550-700 in the right, that is
easily done by setting the shift. Set the shift for the left as you want it
for main RX. Then hold BSET to get b SEt display, the shift control will
now move the heard tones bandwidth in the subreceiver. Adjust the shift for
the right ear.

There are a plethora of adjustments available in the K3, and they are being
extended by Elecraft based on the user community. Takes a bit of time to
learn them.

73, Guy

Shift won't change the pitch/sidetone, it will just change the passband. It will attenuate the level of the cw signal as the passband moves away from the sidetone frequency, but it won't change the pitch.

Re: Separate CW Pitch for Main and Subreceiver

In reply to this post by Guy, K2AV

Thanks, Guy, that appears to work. I should have thought of that
myself, I guess, but somehow I thought PITCH would be separately
definable for the subreceiver.

I used BSET to shift the subreceiver about 150 Hz. I've tried it both
directions, but lower of course gives me the greatest percentage
difference. As I tune VFO B the signal in the subreceiver peaks at the
different pitch and it's easier to distinguish it from whatever I'm
hearing in my left ear. I currently have it set for 640 Hz in my left
ear (my preferred tone) and 500 Hz in my right ear.

I was kind of hoping for a method that was independent of passband
shift, but I'll gladly settle for this one. Thankfully it holds as I
change bands.

Thanks again!
