An FTDX10 operator reports that changing band from OpsLog moves the rig but the
displayed frequency stays on the old band until they nudge the VFO. The existing
readback is taken immediately after the write, so it always shows the old value
and proves nothing: OmniRig queues the CAT command and sends it over serial.
A second readback is now logged ~1.5 s later, from ReadState (the goroutine that
owns the COM apartment), together with what OpsLog concluded. That separates the
two candidates, which look identical to the operator: the rig ignored the write,
or the rig moved and its rig file never re-reads the frequency.
