On Tuesday, local TV antenna users will notice static across the airwaves where station KOPX-TV-ION Media Networks 62 used to be.

In an ongoing effort to realign the use of the public's airwaves, television stations have been implementing the move to different frequencies.

Some area stations have already made the switch, like KAUT-TV-Independent 43, which moved in December.

On Tuesday, local TV antenna users will notice static across the airwaves where station KOPX-TV-ION Media Networks 62 used to be.

As 35 area stations complete the transition, local antenna viewers will simply need to rescan their TVs and converter boxes to continue reception.

According to a TV Technology survey, at tvtechnology.com, 17 percent of U.S. households still rely on broadcast-only — also known as over-the-air (OTA) — television reception.

What happened

The Federal Communications Commission (FCC) in March of 2016 commenced the first-ever incentive auction designed to repurpose spectrum for new uses. Authorized by Congress in 2012, the auction used market forces to align the use of broadcast airwaves with 21st century consumer demands for video and broadband services, the FCC states on its website, at fcc.gov.

According to the website, the auction preserves a robust broadcast TV industry while enabling stations to generate additional revenues that they can invest into programming and services to the communities they serve.

By making valuable low-band airwaves available for wireless broadband, the incentive auction will benefit consumers by easing congestion on wireless networks, laying the groundwork for fifth generation (5G) wireless services and applications, and spurring job creation and economic growth, the site reads.

Bidding in the auction closed on March 30, 2017, repurposing 84 megahertz of spectrum — 70 megahertz for licensed use and another 14 megahertz for wireless microphones and unlicensed use. The auction yielded $19.8 billion in revenue, including $10.05 billion for winning broadcast bidders and more than $7 billion to be deposited to the U.S. Treasury for deficit reduction.

On April 13, 2017, the transition to new channel assignments started.

According to National Association of Broadcasters, at nab.org, as part of the broadcast spectrum incentive auction, the FCC was authorized to repack the television band by assigning television stations to new channels. This process poses significant challenges for the broadcast industry. Repacked television stations will need to complete channel moves. Radio stations and non-repacked television stations may also be affected if they are located on or near a tower with a repacked television station, the NAB reports.

By law, TV stations started moving to new frequencies at different times since the fall of 2018 and will continue through at least the spring of 2020.

Nearly 1,000 stations are being moved to new channels.

The undertaking for the broadcasting industry is affecting nearly 73 million over-the-air television viewers across the country.

According to tvanswers.org, a resource from the NAB, what that means for those who watch TV for free using an antenna, a rescan is necessary to keep the channels. Any time after a station moves, rescan the TV or converter box to continue to receive local TV stations. Rescanning is when the TV finds all of the available channels in the area. Because stations must move at different times, a rescan of the TV may need to be done more than once, the site states.

No new devices, equipment or services are needed to rescan.

How to Rescan

If a TV hasn't been rescanned recently, there may be other TV channels available, the site reports.
