Brian,
it is MCU 5.29 from June 16. 2015. I didn't try the latest beta yet.
Before I roll back to a former FW I'd like to share my thoughts and
experiences cause its perhaps me doing something wrong.

Hi Udo,
Very nice setup.
You don't say what firmware you are using.
Can you revert back to an earlier version?
If earlier firmware version works then you can blame the new firmware.

Sorry, forgot to mention: it's a K3 (serial 59xx) issue here.

Gents,
with the last firmware release I'm struggling with diversity mode. I was
running diversity for a very long time without any issues on my Xpol EME
system (144 MHz). The main RX is fed with the H-Pol signal from my
transverter #1 via KXV3-A, the sub RX is fed with the Vpol signal from
transverter #2 at AUX input. Both transvertes are in exactly phase by a
common GPS controlled LO. In diversity mode the signals were stereo at
line out, with Hpol on left and Vpol at the right channel. It was
exactly the same on my headphones.
With the latest firmware release there's no stereo signal at line out
anymore and I recognize that strange "hum hum hum" phase shifting on my
headphones. On line out there seems to be either a mono signal mixing
both channels to one or just the main RX on both left and right. I can
see this clearly on my WSJT system, when Hpol and Vpol signals are
eaxctly the same now. There's no difference anymore, even that there
must be some.
When diversity is off and main RX and sub RX are exactly on the same QRG
things are like they were before: main RX on the left and sub RX on the
right channel on both line out and headphones.
Anything worng with the latest firmware release, is this a new feature,
a bug or is it me doing something wrong?
Have no idea.
