Both conditions need to fixed.  VFO-A needs to be set as selected VFO and VFO-B 
set to the split freq at all times.  Otherwise a tune instigated from an 
external source will be on the wrong frequency.And yes...I know you can click 
Tune in WSJT-X and then VFO-B gets set...but that leaves the amplifier in-line 
with too much power to tune and for some could fry the amplifier.

The same is true if VFO-A is the active VFO; VFO-B does not get set with a band 
change until you transmit.
I just hit WSJT-X's "Tune" button for a second when switching bands. Works fine 
on the IC-7300 with tune-on-PTT enabled.

Found an undesirable behavior that I think can be easily fixed.
On ICOM rigs hamlib assumes split is always on VFOB to cover rigs without 
status commands...as does FLRig (and perhaps others).
If VFO-B is the active VFO and you switch bands on WSJT-X only VFOB gets 
set...VFOA does not change...so it appears to do a reverse split and tuning 
can, of course, be way off depending on where VFOA is sitting.  Once you click 
transmit VFOA does get changed but by then it can be too late for your tuner.
I believe all that we need to do is make VFOA the active VFO when switching 
bands before any frequencies are set.  Is there any reason not to make VFOA the 
active one?
