I'm thinking for this up coming contest season, inviting over a bunch of 
non-contesters to give them the experience and maybe get a few more bit 
by the contesting bug. And this loos too good to be true, the 
distribution machine AND 4 headphones?  this if it works would be great 
to have so rveryone near the radio can have a headset, and even maybe 
use one of the outputs for a regular speaker too?

My question is do you have one and how well does it work?  how about 
RF?  does it have any problems with RF? My computer has nice sound 
system speakers for music  sub woofer and all that But i have to shut it 
off when transmitting because RF gets into it. (everything is plastic.)

so  anyone?
