But don’t be alarmed.
The title sounds like click-bait but it’s true. All around the USA, during 2019, some TV channels will stop working. This is because the FCC has ordered them to change to a different frequency. In my area, there are four channels, including PBS that will be changing frequency. This may happen several times during the year in your area since different TV stations have different dates for implementing the change.
Fortunately, it’s no big deal nowadays. When your favorite channel “disappears”, just tell your TV to rescan for channels. It will find the new frequency and everything will be fine.
The change is something of a hassle for the transmitters themselves. It requires changes and adjustments to their equipment and modification or replacement of their antenna(s). But this doesn’t affect you.
The NAB (National Association of Broadcasters) has a web site here http://www.tvanswers.org/ to help with your questions. You can enter your zip code and get a list of coming changes in your area by station and date.
