Before we go off and  buy a bunch of these pups should we do some level of 
qualification to see how suitable they are for radio work.   Touch of 
concern on how much noise these may generate  - would hate to see us go get 
a bunch of these and get surprised when we find out it has hash all over 
the place etc.

Not exactly sure what level of qualification we should try and do - perhaps 
fire this thing up with some load on it and sweep a radio around and see 
what it sounds like -- or sweep a spectrum analyzer around and see what it 
show.

Cheers,

Bill (kd5tfd)
