[TenTec] Using Non-TT Supply

[Paul Kraemer]

I can't add much to that except during a recent fault in the OMNI VI the 
fuse in the radio did not blow, the ASTRON protected it against the over 
current as it is supposed to.
I put a lot of faith in products made by companies where that is their only 
product.  If they weren't doing it right they probably wouldn't last
