That's not quite correct. There is also a cable that runs from the
connector on the rear panel of the 746 to the tuner. This connector is
commonly used for the Icom AH-4 style tuner. Rather than the LDG tuner
simply sensing the RF, this cable commands the unit when the rig is tuned. I
had wrongly assumed that it would also tell the tuner what frequency it was
on. If I had done my homework I might have discovered this.

    It's not a show-stopper - only a very minor inconvenience. I wanted to
pass it along for anyone else that might make the same assumption.

  Well, sure. The only thing going from the radio to the tuner is
  the antenna cable, so the tuner has no way to know that you
  have changed frequency on the transceiver. Whereas a tuner
  built into the radio, or one made for the radio you have and
  connecting to the radio with a control cable, can get frequency
  information from the radio. But the third-party tuner only knows
  you have changed frequency when you tickle it with some RF.
