[FADCA] Central Florida Backones working again.

[bud thompson]

Thanks Rick - ... maybe we'll take a ufh beam and HT up on the roof of the 
building and do some fox hunting.

Now.. remembering I'm not a TV kinda guy  wouldn't a TV signal be pretty 
broad - and maybe I can't see it on the spectrum analyzer (other than the 
blip).. Wonder if this could be the cause of our 440.050 receiver having a 
higher "s" meter reading w/o a packet signal on it than any other Mitrek we 
have?
