Mississauga hasn't moved (yet). It is a map error. It is funny.

Very weird! I didn't think an RF could display different virtual channels at the same time. Wouldn't the receiver get confused?

The receiver won't get confused.  Just like WIVB can display  and  without and channel number in-between.  The only concern that the FCC has in the U.S. to a station's virtual display is that it does not conflict with another station's virtual channel in the same market.  (In Buffalo, WIVB has exclusive rights to virtual .)

The mandatory requirements for assigning the major channel number component of stations’ virtual channels are set forth in Annex B to ATSC A/65C, which first lists the major channel number assignment provisions and then explains in subpart 8 that “[t]he provisions listed above assign major_channel_number values 2 through 69 uniquely to broadcasters licensed to broadcast Digital ATSC signals and guarantee that the two-part channel number combinations used by a broadcaster will be different from those used by any other broadcaster with an overlapping DTV service area.”13 This ensures that broadcasters who built their brand in a service area on a particular channel can retain their brand identification even if they are no longer using the same RF channel on which they built their brand ,and that consumers associate with the station.14 Section 73.682(d) and Annex B are self-effectuating, and the Commission’s involvement in virtual channel assignments ordinarily is limited to situations where a station chooses a major channel number and another station objects, or a station requests a waiver of the mandatory channel assignment provisions of Annex B.15 The vast majority of operating full power television stations were transmitting a licensed analog signal prior to the end of the DTV transition in June 2009, and accordingly, are currently using their former analog channel number as their “virtual” or “major” channel number.

So when is WIVB really going to switch from RF 39 to RF 32? A previous post hints it's already done but as of Thursday, Jan 25, they're still on 39. There has been nothing said on Ch4, on their web site, in the Buffalo News or any other form of the media except here. Where did the switch date of Jan 23 come from?

Channel 2-4 Quest. Coming soon. Preview on now.

Was wondering about this! That's great - its too bad my reception is no good for channel 2 (RF 33).

Guys, please be careful with information that you're finding in the FCC databases. It doesn't tell the full story. My name is Steve Yoder. I'm the Assistant Chief Engineer for WIVB-TV and WNLO-TV. We are not changing frequencies this weekend. The transition will not be happening for several months yet. I promise it will not be a secret when we make the transition. When it's coming, you will know about it. It will be very public.

Thanks for watching.

Steve, thanks for the information. I would expect Ch 4 and the Buffalo News to announce when this transition will take place.

Happy to pass along the info. We will definitely make sure everyone knows when the transition is coming. We don't want to disappear on our viewers. We'll make sure we let folks know when as well as what they might need to do to find us after the transition. Some TV's should be able to find us on their own, but others will need a channel scan. If you guys ever have a question or concern related to our OTA signal, feel free to reach out to us directly. We don't bite. My work email is in my profile.

Sorry for the misinformation.  There is an FCC (PDF) document somewhere I will find, that has January 23 as the date of WIVB's RF 39 signoff, plus this from the FCC release DA 17-314 Released: April 13, 2017

3. Channel Sharing Stations
76. A channel sharing station (113) must implement shared channel operations, and a sharee
station must discontinue operations on its pre-auction channel, within 180 days after the sharee receives its share of auction proceeds.  114

Also, was told from someone at the FCC (as I posted earlier somewhere) that a station is considered to have received payment 5 business days after the release of the documents.

Sorry...

I found the FCC document, WIVB is listed as Nexstar, facility i.d. 7780 with the date January 23, 2018.

I guess they're wrong...

WIVB on Rf 39 was granted a 90 day STA extension.They have until end of April to move to channel share on Rf 32.

I think it would be beneficial if when posting information about channel changes, the source would be identified. Otherwise it may be just a rumor.

WIVB has STA granted until april 23rd 2018 to continue on RF 39.Source FCC, LMS Application search WIVB.

Thanks for the info...I usually don't post of the weekend.
