Good point. I hadn't considered flying metal.

What's with these exciters. I'm hearing many people complain that 
they're out of service more than they're in. Locally, my NPR station 
has had assorted problems requiring the unit to be sent back for 
repair. It seems IBUZ is turned on when someone wants to play with it 
and off when they're done.

I find the same lack of attention in HDTV. It's as though no one is 
monitoring it.
