Hi Howard and Others,

I had a set of wireless headphones and they operated wide band FM. The 2 
channels were in the 911 MHz and 916 MHz range.  The left and right 
channels were in those 2 ranges.   I can't remember which channel was in 
which range.  The model I had from Radio Shack had 5 channels and of 
course when you changed channels, the 2 frequencies changed simultaneously.
