fix: split read (and set) backwards on a Yaesu reporting the TX VFO

Browse Source 
Reported on an FTDX101: the panel showed split ON with the radio OFF, and the
reverse — while the same model behaved correctly for another operator, and an
FTDX10 was fine throughout. That pattern is the clue: one operator was on MAIN,
the other on SUB.

The two commands say different things and were read alike:

  ST is a split FLAG   — ST1 means split, whatever VFO is in use.
  FT names the TX VFO  — FT0 = transmit on A, FT1 = transmit on B.

Split is on when the rig transmits on a DIFFERENT VFO from the one it listens to.
Reading FT1 as "split" is therefore correct only on VFO A, and exactly inverted
on SUB. It is now compared with the current VFO.

Writing had the identical fault, and it was worse: sending FT1 for "split on"
while the operator listened on SUB CLEARED the split it was asked to set. Both
directions are pinned by tests over each VFO state.

"Clicking a cluster spot while listening on the SUB VFO no longer pulls the radio back to MAIN. The command used to tune sets the main VFO by definition; on SUB the sub VFO is now written directly and the VFO selection is left alone."

"Split showed the opposite of the radio on some Yaesus. Where the rig reports which VFO transmits rather than a split flag, that has to be compared with the VFO you are listening to — so it read backwards for an operator working on SUB and correctly for one on MAIN. Setting split had the same fault."

"Cliquer sur un spot du cluster en écoutant sur le VFO SUB ne ramène plus la radio sur le VFO principal. La commande utilisée pour s'accorder agit par définition sur le VFO principal ; sur SUB, c'est désormais le VFO secondaire qui est écrit, sans toucher à la sélection."

"Le split affichait l'inverse de la radio sur certains Yaesu. Quand la radio indique quel VFO émet plutôt qu'un indicateur de split, il faut le comparer au VFO écouté — l'affichage était donc inversé pour un opérateur travaillant sur SUB et correct pour un autre sur MAIN. Le réglage du split souffrait du même défaut."
