How KTRK-TV shares transmitters
During the switch, stations in a market pair up: one transmitter (the “lighthouse”) goes NextGen-only and carries everyone’s 3.0 versions, while its own old-format programming moves to a partner. Your TV shows the same channel numbers either way.
- KTRK-TV’s NextGen TV version airs from KTXH (MY NET 20) (RF 19).
Questions about KTRK-TV
Is KTRK-TV broadcasting in ATSC 3.0 (NextGen TV)?
Yes. KTRK-TV still broadcasts its regular signal from its own transmitter, so nothing changed for your TV. A NextGen TV (ATSC 3.0) version also airs from KTXH's transmitter (since December 2, 2021).
Will KTRK-TV stop working on my TV?
Not under today's rules. Any full-power or Class A station that switches to NextGen TV must keep an old-format (ATSC 1.0) simulcast on the air, and that requirement has no end date. What could change it: broadcasters have asked the FCC to let full-power stations in the 55 largest markets end old-format signals in February 2028. The FCC's own October 2025 proposal leaned the other way — letting each station choose when to stop. A final decision is expected by the end of 2026.
Why can't I get channel 13?
Start with a full channel rescan (Settings → Channels → Auto scan) — stations change transmitters and frequencies more often than people expect. KTRK-TV transmits on real (RF) channel 13, which is VHF-high. Many flat and "HD" indoor antennas are built mainly for UHF and do poorly on VHF-high (channels 7–13). If this station drops out while UHF stations come in, try an antenna that lists VHF-high reception, or one with rabbit-ear dipoles extended.
