No, I'm set flat in rx eq. Was easy to zero beat using 20mHz WWV and the
procedure.
Thanks!

Is your RX EQ set to roll off lower freqs? The 1-5 Hz zero beat note is easily
heard when listening to the WWV carrier beating against the CW spot tone on the
K3.

When there are two tones closely spaced in frequency, they will produce

I have used Fldigi and its WWV analysis mode to do the same thing by
off-tuning the WWV carrier by 1 kHz. Of course, that presumes that the
sound card is accurately calibrated.

The easiest and most reliable way for me to calibrate my K3 using WWV is to
switch between sidebands when a tone is being transmitted. When the two
tones are equal in pitch, the rig is calibrated.

Just another note:My K3 will not produce a audio tone below 200 cycles in
the speaker.. ( could be my ears) so finding a zero beat is impossible as I
could be off that much above or below WWV trying to callibrate that way.

I use a program called Spectran ( freeware ) which will display the audio
frequency of the output of the K3
I set the Frequency of the K3 to .000 kc (usb) this will produce a
1kc tone to the sound card in the computer when tuned to WWV at 10 mhz
Spectran will then display the frequency of
I have s/n 3012, factory built. On a few occassions I have been told by a QSO
partner that I am tuned a bit high. It has happened infrequently but I decided
to check against WWV.
Three questions:
1) is comparing to WWV a good method to confirm display accuracy? I used my P3
