Program guide update / channel frequency

3478 Views 17 Replies 6 Participants Last post by  JosephB
Local TV station KFLA changed frequencies but still reside on 8.1, 8.2, 8.3 etc.. It's been a couple weeks and there's no program guide data so there's no season passes recording.

This channel is better than TVLand with lots of good old shows from the 50's through the 80's.

Do I notify Tivo or Tribune? or just wait a month?

Did rescan channels? What does zap2it have?
Thanks, yes, I did rescan, twice. Zap2it has the correct data however, so did Tivo before I rescanned. The station only changed frequencies, not channel numbers.

Prior to rescanning I had program guide data but no reception, now I have reception, but no data. Neither works very well for recording. :)
Ok. Are the channels showing up in the TiVo guide, just with no program data? If so, then contact TiVo.

If they are not showing up at all, then check in "Channel List" and make sure that they are selected.
I'm not sure, but does that scenario fit the normal case:

Thanks, I just filled out the form. I will probably call later today. I'm scanning again now because I know they will ask if I did it lately. I don't think Tivo knows that their guide data is aiming incorrectly. They have correct data for the correct stations, but not on the right frequencies.
I gave this some more thought, and I am totally confused. How can a station keep the same channel numbers but change OTA frequency? If it were cable clear QAM, yes that can happen. But OTA?

One more thing you might try if you haven't already - redo guided setup.

I just finished the entire guided channel setup. Nothing changed. There are two 8.1's, two 8.3's. One of each shows the guide, one of each shows a picture. Neither shows both.
Hmm. And you have your antenna hooked up to the "Antenna In" and nothing connected to "Cable In"?

Just spend an hour with Tivo support. KFLA is now transmitting on frequency index 8 instead of 52 because of a mandate by the FCC. They couldn't transmit on 8 before because of interference with San Diego. KFLA is a very small independent station in Los Angeles.

On the channel list screen it shows

8.1 KFLALD frequency 52 <---- shows correct guide, no picture (old)
8.1 KFLA-RT frequency 8 <---- shows picture, no guide (new)

Anyway, the tivo tech finally understood what is happening and it will take 10 days or so to take effect. Time will tell.
Really not surprising that this was causing a problem. It is a very weird situation. One wonders why there were two channel 8's within interference distance of each other. Why wasn't KFLA on channel 52?
Recently, there was a similar problem with a Minneapolis station. I put in a lineup issue report with tivo and then when that failed I contacted the station directly and a tech there contacted TMS directly and the issue was resolved, but it did take a little time.

Yes, the OTA channel number has no relation to what frequency is involved. Switching over from analog to digital required frequency changes, but the stations considered the channel number part of their branding. So the ATSC standard allows virtual channels. A station's digital broadcast carries its virtual channel number which is picked up during a channel scan, and is used by the device's interface. The device maps that virtual channel to the real frequency.

Although the deadline of 12/31/2011 was a bit of a surprise, it was known all along that channels 52-69 (700-800MHz) were going to be vacated.

I understand that. What I don't understand is why channel 8 was assigned to frequency 52. The only way this makes any sense at all is if they were originally channel 52.

OK, I can think of a way - they never existed as an analog channel and there would only be interference with the San Diego station in analog. So they were assigned to frequency 52 with the understanding that they would have to change frequencies at some point after the digital conversion was complete. I don't know if this is possible from a technical standpoint but it is the only explanation I can come up with.

I posted the link that explains the history of the channel and why it has moved around. http://www.kfla.tv/Viewer_Notice_1.html

So basically, the FCC didn't do a very good job of performing the one duty they were created to perform.
The only VHF frequencies not broadcasting a network in LA are 3,6,8,10, and 12. I think all those frequencies are in San Diego, so its a matter of limited power and limited direction for any new station, like KFLA to get any airwaves in the LA area.

When I scan for channels using only my rooftop antenna, I get 142 signals locally. Granted most of them are foreign, religous, educational, informercials, and near worthless subchannels, but it shows how congested the airwaves are here.
This happened recently here in Birmingham, a local station added a subchannel and TiVo had the wrong frequency, so there was a blank channel with the guide data and the actual scanned channel had no guide data. Submitted a line up form and they fixed it in 3 days.

If you can provide the frequencies TiVo *thinks* the channel is at and where it actually is, I think that will help better than anything
