P3 Strange Display Behavior on BSET

[Stan Gibbs, KR7C]

I'm running P3 firmware 1.05.

If I have my SubRX enabled and the two receivers tuned to two different signals, my P3 cursors are displayed exactly as expected.  If I then hit BSET, the P3's VFO A cursor and display (including the displayed VFO frequency) shift to the VFO B frequency, despite the fact that the audio for both RXs does not change, indicating no change in the VFO A in reality.  This also results in an incorrect display for the VFO B cursor because it is displayed as though it were tuned to the VFO A frequency.  Tuning the VFO B is no longer synchronized to the P3 display.

Turning off BSET returns the P3 display to the correct state.

Has anyone else seen this?

Hi Stan,
I turned on my KRX3 and BSET.  My P3 display did not show the VFO B frequency and the cursor remained with VFO A.  When I pushed ALT, VFO B did change to the opposite sideband as expected.  Roy Morris  W4WFB

I think that the aberrant BSET behavior only occurs when the diversity
mode is on.  This is related to the front panel display (and the SUB
receiver) switching over to VFO B during BSET, but I don't see it when
not diversity.

I confirm the bug when in fixed-tune mode.  I'll add it to the list,
thanks.

Thanks for the confirmation, Alan.  I was aware that the behavior was only present in fixed-tune mode, but forgot to mention that fact in my posting.  

The fix will greatly improve SO2V operating with the P3.
