Chicago area is getting an atsc 3.0 lighthouse. Our local cbs affiliate is moving all their channels (main and 4 sub-channels) to different frequencies. The new sub channels are not mpeg2 encoded. They are AVC encoded. My Tablo 4th gen guide doesn’t list them.
In Chicago, the “new” ATSC 1.0 channels are live and simulcasting with the originals on RF12. RF12 will shut down/convert to ATSC 3.0 Monday 2/5 around 1PM CST.
According to posts on the AVS Forum Chicago thread, the new 2.1 (RF19 WGN) and 2.3 (RF24 WFLD) are MPEG2. 2.2 and 2.5 (RF34 WGBO) 2.4 (RF33 WMAQ) are MPEG4.
The tropo interference in Chicago is mostly over with now. Able to get all the channels.
The new 2.2 Start TV has switched back to MPEG2, so it is now usable on a Tablo.
48.3 has changed from a simulcast of 2.1 to Catchy Comedy. But, it still shows up as CBS on the Tablo scan. I guess it may take a few days for everything to get updated.
On a TV directly connected to an antenna, the channel name is CATCHY, but the program info also still shows CBS. I think Weigel still has to get their act together (it’s a Weigel-owned station.)
