San Francisco, CA - OTA - Page 297

I am a bit late posting regarding poor reception here in the North Bay, but we had problems with severe pixillation with a new show "Revolution" which was broadcast on HD KNTV 11.1 last Monday at 10PM. Since I TiVo'ed it and did not watch anything else that night on KNTV, I do not know if it was a problem on KNTV's end or mine. Usually when we have pixillation problems we also have short dropouts in sound too but not then.

Regarding Fox 2.1, we rarely have any problems.

Do you or anyone else remember having recent problems with 11.1 last Monday?

Bob

It must have been KNTV. I had the same problem with Dish. They get their signal OTA as well, but from a much closer reception point.

Update TV.

Airbox.

No clue, but I can guarantee you they are not for Mobile DTV, since Mobile DTV cannot be decoded by traditional TV sets. Shoot me some TSReader data and I'll have a look at what you may be seeing.

CQ San Francisco.....CQ San Francisco.

Two weeks without a new post in San Francisco is rare.

The KQED, 30.8 and 30.9 channels are Update TV service artifacts:

Three and a half years after the transition and I guess all reception problems have been solved. The AVS Official Antenna topic is dead too - no reception issues. The only changes left are the end of LP analog in 3 years (When if ever are all those LPs going to transition?) and the FCC auction of UHF broadcast spectrum (Is anyone going to participate?).

Chuck

And all the LP analog 6 turn to digital. Bye bye FM radio.

That doesn't make a bit of sense since the LP 6 analogs have been exploiting a loophole that allows them to be licensed as a TV station but to broadcast as a de facto FM station.

FM radio itself is doing well enough as it is and there is absolutely nothing on the FCC's announced drawing bard that will change it. If anything, the FM band could be expanded lower into channels 5 & 6 with minimal impact nationally to the TV broadcast industry, IMHO.

Hi,

 

It sure needs expanding here in the S.F. bay area.

 

It took a year and a half for the one radio station I listen to come back on the air after it was deemed redundant. (KDFC FM 104.9, 89.9, 90.3 And worldwide at KDFC.com.) USC was ready with the money right from the start.

 

Now back as strong as it was before.

Anybody else using KTVU's fill-in transmitter on RF channel 48? I get occasional moments of pixelization and poor audio, lasting a minute or so, that I never got on their main transmitter. I'm using an HDHomeRun and MythTV. Monitoring using the HDHomeRun software during these break-ups shows a continued good signal quality and symbol quality. I'm kind of puzzled by this.

This sounds just like the problem KGO was having with their channel 35 translator. That turned out to be dropouts of KGO 7 at the receiver on Mt. Allison. That will give you the symptoms you saw. I don't know how the translator is getting the signal but simply receiving KTVU on 44 is likely.

Chuck

I've added these two channels to my monitoring script, results will be here for RF 44 and here for RF 48. Only two data points as i post this, but graphs will be prettier later (signal doesn't look very good on 48 right now though)

After a few hours of sampling, my graph of RF 48 looks pretty bad. If this is a similar problem to RF 35, it's much worse; but the signal strength number I'm seeing is pretty low (~50 on HD Homerun), so it might just be the digital cliff?

Hi,

 

Every time I click on your links I get nothing of value, please stop wasting our time.

 

SHF

Don't speak for me. I find his graphs interesting. If you don't like his links, don't click on them. Let the rest of us decide for ourselves.

Hi,

 

I just told him that I was getting nothing. ZIP, NaNa. He said it should display automatically and would fix it.

 

I made other suggestions when he returned a sample picture.

I am using ie9 and can read his graphs fine.

Hi,

 

Are you using your X-Ray Glasses?

 

He said that it just would appear, no instructions necessary.

 

I just get a big white space follow by a button that does nothing for me.

Hmmm, it all loads fine for me, graphs and all with FF 16.0.1 on W7.

toast0's graphs work just fine here on Chrome. They use a Google visualization API, which some browser privacy extensions may block.
That seems to be the case for you. Though it looks like the signal quality has improved today.

Works in fine in Safari.

Chuck

Works fine here on two browsers (Chrome and Iceweasel). A third (Konqueror) pops up a message saying "Your browser does not support charts."

- Trip

Was broken for me in IE9 too; I had an extra comma in the javascript; I also put in some html to kick it into standards mode, which makes the google visualization API a lot faster, and I made the charts bigger. (I may still switch to server side graphing, so I can capture the valuable Konqueror market, and/or have an easier time making the labels not suck). Please feel free to PM me any feedback, as I don't really want to clog up the thread.

So is anyone successfully watching KTVU on 48? From the graph I would say not but what about other people?

Chuck

Funnily enough, I haven't had any problems on 48 since my first post! I don't normally watch the station but with postseason baseball season upon us I've been watching more, which is what made me post about the dropouts in the first place. I just hadn't been annoyed enough with them to post...

Hi,

 

I getting a unchanging Signal from RF48 right now here in Sunnyvale. YMMV

 

 

 

KEMO is missing and KRCB just barely shows up. Not a good time for 97 mile reception.

 

SHF

Im only 19 mies from mt allison but as far as reception for RF 48's signal goes it might as well be coming from sacramento. RF 35 at least shows some heartbeat, even if there is no reliable signal.
the new low power transmitters there must have been intended for people on the peninsula who's SF reception is blocked by mtns to their north, or maybe to some nooks and crannies of the tri-valley, because they have done zero to provide any new service to the south bay


im hoping that cooler weather that is predicted for the weekend indeed arrives, this warm weather has a very negative impact on ch 7's reception down here

Looks like both KCNS and KTNC are having PSIP problems *sigh*

If you have a tuner that does not handle duplicates, you might want to hold off rescanning channels (because of the overlap between digital 14 and RF14).

The south bay is served by Sutro tower & San Bruno Mountain with very strong signals. KNTV tower move from Loma Prieta (San Jose) to San Bruno Mt. was approved because the new location gave comparable service levels to the residents of the city of San Jose ..... KNTV is a San Jose based tv station.
You should have no problems with a outdoor VHF television antenna.

I will guess those "repeaters" are for the small town cable systems in the monterey area (Charter Cable) in Soledad. The mickey mouse cable systems have antennas on the towns well water towers and are LOS to that spot.
There was problems trying to get ABC 7 and ABC service to those areas with the distance and Sutro tower being blocked.
I noticed a "Fading" problem with Channel 2 down there on cable. Some small town cable systems are STILL analog.

I do not think those repeaters are intended for the general viewing area already served.

Ion-tv (PAX) Channel 65 Also moved from Loma Prieta (Analog 65) to (Digital 41) San Bruno Mt.
2 San Jose stations that moved towers north.
