I didn't think you had a VHF antenna, though?
I'd worry too. Especially because WPVI analog, on Ch 6, is transmitting an ERP 
of 74.1 KW, whereas in digital, they are scheduled for 7.56 KW, on the same 
tower. That's a 9.9 dB reduction in power. If analog reception is very bad now, 
it seems dicey for digital with such a power drop.
That's also my concern here, with the two local and two Balt channels going 
back to VHF. I'm certainly not counting on getting the Balt channels any 
longer. The power drop in these markets, compared with their analog VHF, is 
even bigger than you have to deal with there.
Suspicious message? There’s an alert for that.
