Just a thought....not sure if anyone ever tried it....or if there would be a reason to not try it (I guess I ask because I was thinking about it)....but
Lets say you used one of the PDA/cell phone sleeve type things to put the transmitter in on your strap and it had extra room it in.....couldn't you just wire up a RC car battery (one of the small ones...4" long or so) with a 9V adapter end.....plug it into the transmitter and stuff the whole thing in the sleeve....and run for a long time (thinking like 10hrs)? I mean those batteries are 9.6V and like 1400mah or better. Seems it would work no? Some of the techie guys here may have a reason it wouldn't....so thats why i ask.
Just thinking outside the box I guess.
