[Elecraft] CW ZERO-BEATING WITHOUT BUTTON PUSHES

[Darwin, Keith]

Tom (& all)
 
Yes, it makes sense.  Next time I'm on the air, I'm going to play with
MON level a bit to see what I get with slight changes to it's volume.

Keith:

The trick I've used for decades is to set the sidetone just a bit louder
than
those signals I'm listening to.  Then, when I zero the received signal,
I tune
it in to the point that it (audibly) "disappears" beneath the sidetone
of the 
same frequency... if it's NOT zero beat, you'll be able to hear the
offset. If
it is zero beat, it'll be hiding behind the sidetone.

I (think I) can provide a short WAV file to demonstrate if you have
difficulty
following the above verbal description.

	Really?  I always try to tune CW by ear and I'm amazed at just
how far off I am once I check it against the spot tone.  I never get it
right without some help.
	 
	I suspect I'm not alone.

recognizable when a signal is being tuned in and "hits" that pitch.
