Steve:
That desk mic idea actually sounds like a possibility. ... I have three
TMV7A's and had actually thought of swapping one of the others out, and
putting it into the RV for our trip.
I know the others don't have this problem.
Then, I could just pick up a desk mic somewhere and use it with the hot one
at home as the base unit.
Any recommendations on a desk mic that would fit the TMV7A?
