CWT

Could someone explain CWT to me.  I use it all the time now because I can never
can quite zero beat the station.  I like a higher tone for may ears and that
causes be to off his zero beat.  But when I use CWT the tuning goes to a low
tone that I am not use to.  Is there away to change the zero beat tone to a
higher frequency?  I dunno if I am explaining it right or not...

I guess this old guy has some hearing issues...

 In our day and age it seems that Common Sense is in short supply.  If you don't
have any Common Sense - get some Common Sense and use it.  If you can't find any
Common Sense, ask for help from somebody who has some Common Sense.  Is Common
Sense divine?

Common Sense is the image of the Creator expressing revealed truth in my mind.

CWT tunes to zero-beat your CW pitch.  If it is finding false zero beat
at a very different pitch, try narrowing the the filtering (WIDTH
control) to a few hundred Hz, tune until you hear the signal in the
passband with CWT on and see the signal in the CWT moving dot display ,
then tap SPOT.

The capture range of CWT is about +/- 125 Hz.  If there are multiple
signals in your passband, that will probably confuse it.

  Lee,

It will adjust to the pitch that you have set for the sidetone.
Hold the PITCH button and adjust it to something easy for your ears to hear.

You do have to get close to the proper tone before the auto-spot will work.
You may have to adjust the threshold - see the CWT and SPOT instructions
in the manual.

Further, the CWT algorithm requires a reasonable signal-to-noise ratio.
If the signal is noisy, CWT won't find it.
