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. 73 Udo, DK5YA
