It's there alright but Tribune Media has not added it to the on-screen program guide (the whole schedule is "To Be Announced"). Interesting it's not adjacent to THIS 17.3 on channel 467. 468 is open.
Until Tribune Media updates the guide listings, Tivo and other DVRs will only be able to record manually.
Now, when do we get RTV (69.3)
Comcast here in Bristol, Connecticut added Antenna-TV 2 weeks ago on Channel 376 and the whole thing is still "TO BE ANNOUNCED" along with no call station named listed for 376. Meanwhole COX Cable which serves nearby Southington, CT (where my mom lives) says the guide got listings for Antenna-TV within 3 days of them adding the channel. First on 806 on January 1st and then moving to 810 (next to THIS-TV) a couple days later.
