No matter how the transceiver VFOs are set when first powered, it only takes a wsjt-x band change to get both VFO synchronized with wsjt-x. After that VFO A is set for every band and then checked at the polling rate. VFO B is set for every band change and is re-set anytime the TX cursor moves into another 1000 Hz segment.
Since VFO B is only set, but not monitored, by wsjt-x it would be possible to have the VFO B freq wrong if it was changed since the last time it was set by WSJT-X. However, as I indicated, my VFO B was correct.
It is possible that the other op, if using wsjt-x in dual mode, had somehow miss-set his VFO B.
When I first posted I thought this was just a curiosity. Since then, two other ops have reported seeing the same thing. I didn't check if we were all working the same station.
