Sorry, but I did not look at your link until after I sent my response.
While that DIP version may work in a K2, I doubt that it can be squeezed
into a KX1.

If getting to exactly the sidetone frequency works, an instrument tuner box (or
app) might do the job. I don’t know enough to recommend one, but I see some
devices for $30 or less and some apps ranging from free to a few dollars.

You will enjoy your KX1, as I have mine. I made thousands of QSO’s. If you
can “zero-beat” within approximately 100 Hz this should be plenty close most of
the time. I am a musician so I just adjusted the tone a bit above high C which
is an octave above middle C. Actually a D is 587 Hz, which

Ref the linked article - "you slowly tune the received signal until it reaches
the magic tone that means "zero-beat". Usually, this is the same tone as your
CW sidetone, 500-800 Hz, depending on your rig. You need a good ear for pitch."
Has everyone forgotten what to "zero beat" means or is it

If you do not have perfect pitch, then what you are doing is one way.
Another way would be to build a tone generator for your preferred
sidetone pitch and use that.

OK that is a different issue to that which I think many folks understood

to detect and fine tune. Indeed, it is a regular requirement, not a do

Ted,
Is the value you have set in PITCH the same as the audio frequency you
are listening at? If so, the SPOT feature should be quite accurate.
Actually, between the CWT indicator and the Auto-Spot feature of the K3,

HI,
In a pileup, I ALWAYS move off zero beat, so if I transmit, I don't

I have never been convinced of being accurate on zero-beat on my K3.
With previous radio units, I would zero-beat by matching the tone of the
received station with my own keying side-tone. But it does not seem
accurate on the K3.
So the question: How would I determine that my offset and side ton

Hello all,
Don't worry about zero-beating to find the other ops frequency!
Just add a K6XX CW Visual Indicator to your K1, K2 or KX1. All you do is
tune onto a signal until the LED starts flashing to the cw. That's it -
