That date is next Wednesday, December 8, at 2:05 AM. (That is right at the start of "The Insider" entertainment show, for those who are insomniacs like yours truly.)
WCPO has, if you recall, been working over the last few weeks to get their signal switched from RF Channel 10 to RF Channel 22. (Your TV displays that RF number as channel 9, through the use of PSIP technology.)
Here's the WCPO release from their own website:
CINCINNATI - WCPO, Channel 9, the Tri-State’s ABC affiliate, announced today that on Wednesday, December 8 at 2:05 a.m., the station will transition to its new, 910 kilowatt (Effective Radiated Power) transmitting facility. WCPO’s signal will move from its current VHF frequency to the stronger UHF band. The new transmitter and antenna will increase WCPO’s power by 300% and allow the station to broadcast a stronger signal to all parts of the Tri-State.
According to WCPO Vice President & General Manager Bill Fee, “The investment in the new, more powerful broadcast equipment will address over-the-signal issues some viewers have experienced since the digital transition, and prepare WCPO for exciting new services such as Mobile Television. This project powerfully demonstrates WCPO’s and its parent company, Scripps Media’s belief in, and commitment to, over-the-air broadcasting in the Tri-State.”
On December 1st, the station will kick off its “Plan to Rescan” campaign to make Tri-State viewers aware of the upcoming changes, and what they need to do to receive the new, stronger signal. Because of the move to the new transmitter and antenna, viewers who watch WCPO over-the-air (with an indoor antenna such as rabbit ears or an outside rooftop antenna) will need to rescan their digital televisions and/or digital converter boxes. Viewers may rescan any time after 2:05 a.m. on December 8 to receive the improved signal. For questions, WCPO will operate The “Plan to Rescan” hotline on December 8 from 5 a.m. to 12 midnight. The number for the hotline is 513-749-9400.
People who watch WCPO on televisions with DirecTV, Dish Network or cable service will not be affected. Cable and satellite service providers will automatically place WCPO on the correct channel.
Something we need to note, as it seemed to be a point of confusion: If you normally view WKEF-TV 22/Dayton over the air, you should NOT be concerned about losing that channel. WKEF uses RF Channel 51, NOT RF 22 - your TV only displays it as 22 through that PSIP technology. Nor does it affect any of the WKEF/WRGT subchannels; again, none of them are on RF 22 as it was a vacant allocation.
Another point: You'll recall that the switch was originally set to happen on November 15. WCPO decided to delay the switch at the last minute, to prevent confusion and to not interfere with November's "sweeps" period.
That ended last week...but since WCPO opted to warn viewers in advance, it's not happening for another week...
