Yeah, 58.1 has no signal yesterday, 21.1 is still in low power I can't get a reliable lock, all others are good. KVIE 53.1 however keeps swtiching between 53.1 and 6.1 on my 811 receiver therefore get removed from my favorite list all the time, my DTC100 locks it on 53.1 no problem so I assume its the 811/KVIE issue.
On the Comcast cable side, they just added about 15 foreign language channels in their digital tier, who said they didn't have bandwidth for more HDs? Of course those foreign channels probably sell for $15 each. Judging from the fuzzy pictures they probably had squeezed 20 of them on a single 6mhz band so it was a no brainer.
