Wouldn't the net feed come straight from the board, independent of either transmitter?....and (gasp) may have to switch the 'net feed to FM temporarily.

OK...gotcha!Nope. If you do that you have zero processing for consistent levels or "tone" control and...we
take the feed from a tuner to prove what AM can sound like!
And it works! We're the talk of quite a few radio boards. It's great for P.R.!
