Well...that was a gory process to get running...(been following along...).

Now...for the big question...figured out my squelch was nice and loose 
(iow...when I got the stream working...what I heard was hash noise...to 
check, ran radio-tune-menu, tightened up the squelch setting...that 
quieted things down...ok...so, what I'm hearing via the outstream 
command is what's coming in via the RF side.  How about the output to 
the transmitter?

So..what I'm thinking...is stream my hub site which ties all my machines 
together...???

(Imagine my surprise when the darn thing finally came up and all I heard 
was my background noise (obviously radio-tune-menu set my squelch 
setting a bit..ummm...loose....), but, knowing that the net is usually 
pretty active...but that blew half the folks on the hallway here at work 
(it's my last day here at Telcordia...) out of their chairs...)

Well, for years I was smart. I recommend pleasant. You may quote me.
