That Keuwlsoft Audio Frequency Counter is pretty cool! Thanks for
pointing it out.
I found the easiest way to use it is to put the K3 in reverse CW, tune
to 10.00 MHz, and set REF CAL to a setting that "eyeball averages"
best to your PITCH setting. Even with the eyeball averaging, it is

Not sure why nobody has mentioned using WSJT in frequency calibration mode.
It’s the bottom selection in the Mode menu. Shows your offset in Hz to about 5
decimal places. Just pick from the list of standard freqs and away it goes.
Then adjust the K3 ref frequency to walk it in. There are

I find that trying to match two beat notes when I can only hear one at a
time to be hard, best I can do is maybe 10 - 15 Hz Hz depending on the
frequency.
FWIW: The Burdick Calibration Method [BCM] for the K3 is actually much
easier to perform than has been suggested in this thread,it is

You had it fixed, but then you broke it again. After doing the
alternative method on page 49, when you tune in to 10. MHz in CW
mode, you should hear a CW note at the same frequency as your PITCH
selection. I presume that is 400 Hz.
I got an extremely good score on last year's Frequency
Pete,
When using WWV to set the K3 reference, make certain you are listening
to the carrier. WWV is an AM signal that is modulated by a 500 or 600
Hz tone on alternate minutes (440 Hz 2 minutes after the hour). That
produces tones that are both above and below the carrier.
So be certain you

I've been wondering for some time if my 10-year-old K3's frequency
calibration was off, because it seemed like most spots of me were well
off when I clicked on them, usually in one direction. Not having a
frequency counter, I went to the alternative method outlined in page 49
of the manual.
I love my K3, but one thing puzzles me. When I jump to a Reverse Beacon
Network spot (on CW), the perceived audio tone of the station's CW is
almost always higher than where I have my Pitch set, so in order to
center the signal, I wind up tuning up-frequency perhaps 100-200 Hz.
This is not
Pete,
I think you are assuming that the spot frequency is dead on, and I
would believe that is a bad assumption. The other fellow's receiver may
not be well calibrated.
If your K3 receives 15 MHz WWV at the right frequency, I would say your
K3 is calibrated correctly.

Scott, what's the advantage of your iterative process over simply setting
the K3's VFO on freq (e.g. 10.00 MHz) and then tuning for zero beat
using REF CAL as described in Method 2?

My procedure is only a slight modification of Method 2 in the manual.
If you don't have perfect pitch, you can use a technique I recently
described on the Reverse Beacon Network blog, substituting Spectran for
a good ear, which I don't have. See

My procedure is only a slight modification of Method 2 in the manual. The AGC

All frequencies in the K3, including the sidetone, are derived from the master

audio frequency matches the sidetone, the receiver is tuned to exactly the
