ATSC 3.0 or NextGen TV is on its way to Houston and supposedly on air in Dallas - Fort Worth, but a YouTuber in North Texas viewed mixed results on that.
UPDATE NOVEMBER 2021
Houston TV getting ATSC 3.0 December 2021
I've received some notes from Houston television viewers asking me when ATSC 3.0 NextGen TV is coming to the Bayou City. So far on the ATSC 3.0 deployment map, Houston is listed as an "announced target market."
If you are in Houston or anywhere else in Texas, and receiving ATSC 3.0 signals, let me know! It seems like there might be tests going on right now.
