KOIN 6 is moving to a new frequency

KOIN TV has moved to a new antenna on our tower, raising the elevation from 520 feet to 780 feet. This elevation adjustment should help many viewers receive our signal.  Viewers who are not currently receiving KOIN TV’s signal will need to re-scan their television sets to receive the signal.  We are still transmitting on a lower power output and we are diligently working on raising the power level to help the coverage in all of the Portland area in the near future.



KOIN 6, Portland’s CBS affiliate, is changing transmission frequencies on June 1, 2018. Viewers who watch TV with an over-the-air antenna will have to rescan their TVs to continue watching the station. Viewers will not need to purchase new equipment or services, and those who watch KOIN 6 through a cable or satellite service do not need to rescan – your service provider will do it for you.

Main points
  • Rescan your TV if you only use an antenna
  • No need to rescan if you watch via cable or satellite
  • KOIN will remain on Channel 6
  • Change happens on June 1

KOIN-TV is currently transmitting at reduced power on a backup transmitter on channel 25 and your TV will display 6.1 after the scan.  

Due to the reduced output power, some viewers may not be able to receive the KOIN TV over the air signal. We are working on increasing the power level once KOIN moves to our main transmitter.

Currently we are transmitting from an antenna 520 feet up on our tower.  The week of Sept 17, 2018, we are moving to a new antenna at the 780-foot level on the tower that will help many viewers.   

By the end of September, we are on schedule to raise our output power and be on an antenna that all viewers can find KOIN TV on their televisions.

Recently, the Federal Communications Commission (FCC) held an auction of broadcast airwaves to provide more channels for wireless internet broadband services. KOIN 6 did not participate in the auction. However, the FCC is requiring this station and nearly 1,000 others nationwide to move to new frequencies to make room for wireless internet services. In addition to KOIN 6, other stations in the Portland area are also moving frequencies later this year or in early 2019.

TV stations must move frequencies at different times as required by the FCC. This means viewers who use an antenna may have to rescan their TV sets more than once.

KOIN-TV can also be seen over the air on channel 25.1

How to rescan

To rescan on or after June 1, select "scan" or "autotune" on the TV or converter box control menu to start the scanning process. Instructions are usually available by pressing the "set-up" or "menu" buttons on the remote control. This move is happening behind the scenes, so the channel number viewers know will not change. Stay tuned to KOIN 6 for more information, or visit our website at KOIN.com.
