Well, I don't broadcast anything, I doubt the range is very good,
I don't think anyone would complain about it being on an open frequency,
and its only on when I operate, so I wont loose any sleep over it.

I should check the range though, the lower power ones did not 
make it past my yard, and did not work very well in the yard.... 

The one I have may be 1 watt, they sold many different ones in the past,
and I don't remember what one I got. I think its got a power adjustment,
its all software controlled...
If the range is greater then the yard, I can turn it down I guess.

I tried the wireless headphones, they did not work worth a crap,
they are good for a room, not much else.
