[wsjt-devel] VFO readout on FT8 shutdown

[Glenn W. <af...@al...>]

Hello,
Comment: The following Human Induced confusion of VFO frequency occurs 
on FT8 shutdown. Not necessarily a "bug" in WSJT-X. Just thought
I would send out the information.

Setup:  Windows 10, Kenwood TS590SG, USB cable driven, both WSJT-X 2.6.1 
and 2.7.0-rc2. Bands: at least on HF bands.  Everything going well as 
usual.  TX frequency high enough to separate VFO A and VFO B by 1.000 
kHz (RIG SPLIT) in this example.

Action creating problem:  Human manually toggles VFO A/B button. Now VFO 
B is in the main position, VFO A on the side, no frequency changes have 
occurred in either VFO.  Next steps:  EXIT out of WSJT-X. Restart 
WSJT-X.  Now VFO A displays what VFO B was displaying. VFO B is still 1 
kHz higher, which is now 2 kHz from the original.  Examples follow.

TX  = 2800 Hz
  PC          rig        rig
FT8 Display  VFO A      VFO B
24915.00     24915.00  24916.00 <-A on main, B on side. Not in QSO.
Toggle A/B on rig.
24916.00     24915.00  24916.00 <-B on main, A on side. Not in QSO.
EXIT and restart. Symptoms begin.
24916.00     24916.00  24917.00 <-A on main, B on side. Not in QSO.

This effect also might happen on other CAT-based rigs?
Problem with hamlib?
