Rick,
When you say WWV zero beats at exactly 10.000 in USB mode, what exactly
are you "zero beating"? The carrier or one of the transmitted tones?
What happens if you are not in either Split or Diversity - reception on
the main receiver only (turn the SUB off)?
What the P3 should show is the WWV carrier at 10.000 MHz, but the K3
audio will not be receiving that carrier in SSB mode. The K3 will
receive one or the other of the sidebands, so the green band will be
offset from the center indicating the sideband that is being received.
The center of the green band should be offset by the amount of shift you
have dialed in on the SHIFT/WIDTH knobs. If you are using LO/HI CUT,
the amount it should be shifted will be the center of the difference
between the Hi and Lo frequencies.
Normally when you listen to an SSB station, the K3 frequency will
indicate the suppressed carrier frequency - but WWV is an AM station,
and when tuned properly to listen to the audio, you will not hear the
carrier (it is out of the receive passband), but the P3 will still
indicate the carrier of the WWV signal.

Hi all
I have a very odd thing happening in diversity mode after installing the new
VFO's. I have a K3 with dual receivers and new VFOs using a dipole and loop
antenna when in diversity. I also have a P3. I am on current 5.29 firmware
and have successfully gone through all required calibration steps after
upgrading the VFO.
Scenario follows ...
I am listening to WWV 10 MHz in USB mode.
When I am in Split, not Diversity, WWV zero beats at exactly 10.000 MHz.
The P3 green band denoting the K3's passband is nicely lined up with the
upper sideband of WWV.
When I am in Diversity mode, however, WWV zero beats at exactly 9.9985 MHz.
On the P3 I clearly see the WWV signal at 10.000 MHz while the green band
denoting the K3's frequency is just as clearly 1.5 kHz lower.
I can't figure out what is causing this -1.5 kHz shift!
I have had my K3 for some time so I feel I am reasonably competent with it
:) but this has me stumped.
I have asked K3 Support about this but I thought someone out there might
have seen and dealt this this already.
