Yup, this is pretty maddening and I'm only on week 1 of this OTA stuff. Last night with the antenna in the garage rafters I got KNTV but not KRON. Tonight, nothing has moved or changed yet I now get KRON but not KNTV.

I've done battle with PG&E over power line noise for over 30 years mostly for ham radio. It's extremely unlikely that this is your problem. In order for it to be an issue on channel 7 with your directional antenna it would have to be very close by and probably in the channel 7 direction. The thing about power line noise is that it is intermittent. You'd have periods of normal reception and periods of no reception. Rain often makes it go away. Low humidity and north wind make it worse. I think you've said that there are no normal periods.

If moving the antenna doesn't fix it then it's not likely you'll figure it out until you get someone up there with a spectrum analyzer. It sure looks like a multipath issue from your image.

Sounds like both of those stations have a lot of multipath and small changes in the inversions are affecting those stations the most. If you look at the other stations closely you'll probably find they have changes too but not enough to cause dropouts.

This is telling you that the attic antenna is not good enough and you need an outdoor antenna high enough to clear whatever it is causing the problem.

There's no magic with antennas. If the attic antenna doesn't work then you have to go with something outdoors. If that's not an option then it's cable or satellite or maybe Hulu.

The bad reception sounds familiar.. I ended up with a split antennas, a Winegard YA-1713 and a Antennas Direct 91XG, into a combiner, then into a low noise amp from http://www.kitztech.com/, driving a HDHomerun dual.

I still don't get all the stations on Sutro (KTSF is one that drops in and out a lot, ION does too).

Why? Because I have to point the antenna(s) directly at a hill covered with trees to get anything from Sutro/San Bruno. I should take a picture to show that..

I also used the android HDHomerun signal app, plus I found an application written in Python that would do a scan of all the channels, then request you to rotate/move the antenna, and then repeat. This was really useful in finding what direction to point the antenna, esp. when it's not always the direction you thought it should be.

I agree. Noise is probably not the issue. Can’t hurt to ask thou.
Hopefully moving the antenna will help.
I know that moving the antenna had been suggested in the past but that is not a simple task. And why, WHY did the reception go from almost always good for over two years to nothing overnight?? Which is another reason I did not try moving the location of the antenna right away.
The search continues.

I had it on the roof on Sunday night. I found that I could get KNTV but not KPIX when it was on the roof. The whole purpose of moving it to the garage rafters was to get both KNTV and KPIX, which I did on Sunday night but not KRON. Last night I had KRON but not KNTV. Today it looks like KPIX is starting to get a little bit iffy.

It's company policy for all CBS and CW owned and operated stations across the country to NOT have any sub-channels. They allot the entire channel bandwidth to the one channel and it shows in the picture quality! Here in the Bay Area it's KPIX 5 and KBCW 44 and up in Sacramento it's KOVR 13 and KMAX 31.

iitywygms... With good signal strength and good symbol quality, but poor signal quality, as shown in your post, that indicates to me that you have multipath problems. You say it worked one day, then it didn't the next. Did they build something new in your neighborhood, by any chance? You could be getting a canceling reflected signal and moving the antenna might get rid of it. An EMI problem could be the culprit, but I suspect multipath.

Moving the antenna just might solve your problem. I'm located just 3/4 of a mile from Sutro Tower and I can see the tower out my living room window, but I had a mysterious problem with KGO 7 on one of my three antennas here a while back. It was only on the one antenna where the problem occurred. My signal would go from 100%, 31 dB, to 0 at random intervals for about three or four seconds, then it'd go right back to 100%. I figured it was a mix of some intermittent radio signal in the area... ham operator, taxi cab, Muni bus, etc., with some other signal that landed on KGO's frequency. Trying to find it was impossible, so I lowered the antenna 5 feet to see if there was any change. I haven't seen the problem occur since I moved the antenna. I hope you have the same success when you move yours!

You'll be lucky if you get anyone from PG&E that has any idea what they're doing locating noise. The last time I had PG&E out I did all the noise locating and the guy did all the bolt tightening. That worked well.

Maybe. This is off of a nxt2004 connected to a SAA7133 and I don't have the datasheet handy. I suppose I could switch to my HDHomerun if it is important.

I'm in N. San Jose, and still getting KNTV just fine. You can check back a couple of pages to see what I went through to set up my Terk HDTVi indoor antenna.

You'll probably want to post a TVFool report if you want any specific tips though.
post #9644 of 10432
I finally got an initial contact from an engineer at KGO regarding the problems with KGO-35. Most questions were the basic introductory diagnostic questions - antenna type, location, tuner type, etc.
Hopefully something will come of it.

As I check right now, KGO-35 has no picture - been that way since I started looking around 9:30pm. Toast0's data shows KGO-35 dropping off around 8pm.

Thankfully, I switched to using rabbit ears mounted outside for KGO-7 (and KNTV). And the Terk HDTVi, still indoors, for UHF. And combined the two signals with a UVSJ, which works well enough.

Of course, if KGO-35 ever becomes reliable again, I'd switch back to the single antenna Terk setup in a heartbeat.
I hate having to run cable from the outside and being unable to fully close the sliding glass door. I even bought one of those 8" flat coax cables but it's just not thin enough to latch the door. Anyone have any tips?

In the time it took for me to write up this post, KGO-35 has come back a bit - there is picture now, but LOTS of dropouts.

The Terk flat panels are about as useful as a brick on VHF. Swap it for the HDTVi (with rabbit ears).

Hi Larry. I am not aware of anything that has changed in my area. Nothing I can see at least.
Around the time KGO went away we had 4 pge trucks fixing some kind of problem about a half block from my place. Since that time KGO has been weak.
I do not believe whatever they did caused this, but it sure is a big coincidence.
This weekend I am moving the antenna about 40 feet to another location. We will see what happens then.
Thanks for the info.

Hi,

 

When I saw your post I looked at RF 35 and saw missing picture and then a picture with lots of dropouts.

 

Looking at Toast0's chart for RF 35 I did not understand what the drop ~ 8pm in utilitization was saying.

 

Click on the color boxes to the upper right to enhance that line on the chart!

 

Today I went into Toast0's source code http://ruka.org/~toast/atscdata/getstats.pl.txt and spotted that he was using the "get debug command:".

 

See Toast0's more info page http://ruka.org/~toast/atscdata/index.html

 

Silicondust's HDHomeRun Development Guide (20110518)

 

http://www.silicondust.com/hdhomerun/hdhomerun_development.pdf

Quote:

More advanced information can be obtained by using the get debug command:

 

format: hdhomerun_config <device id> get /tuner<n>/debug

eg: hdhomerun_config FFFFFFFF get /tuner0/debug

 

Example output:

tun: ch=qam:33 lock=qam256 ss=84 snq=88 seq=100 dbg=22081-6930

dev: resync=0 overflow=0

ts: bps=38809216 ut=94 te=0 miss=0 crc=0

flt: bps=38809216

net: pps=0 err=0 stop=0

 

Each line contains a prefix to indicate the type of data, followed by the values.

● tun = tuner status

○ see above section

● dev = device status

● ts = transport stream

○ bps = bits per second

○ ut = utilization percentage (100% is filled to capacity)

○ te = transport error counter (uncorrectable reception error)

○ miss = missed packet counter (jump in sequence numbers)

○ crc = crc error counter

● flt = results after pid filtering

○ bps = bits per second

● net = network status

○ pps = packets per second

○ err = packets or TS frames dropped before transmission.

○ stop = reason for stopping the stream

 

The counters are reset to zero upon a channel change, but may indicate a small number of errors

caused before the tuner locks on the channel. As a result, diagnostics should be based on the

change in values over time, and not the initial values.

So utilization dropping to zero was because the channel data was missing (not received) thus the "no picture".

 

"utilization" IMHO is one value that shows the quality of the signal received by the translator's RF 7 antenna pointed at Sutro. The others may be showing the quality of the RF 35 signal received at Toast0's garage.

I find this rather interesting. On a consumer review blog. KNTV is tops in the complaint department on OTA reception. KGO does not have that issue.
I guess not putting all the major networks on the same tower is kinda a big mistake ...... At few years ago they came in here on 48-2 and 11-1, but that is still not sutro tower.

Read what people are saying.
www.yelp.com/biz/nbc-kntv-san-francisco-san-francisco


From my observations at a family members apartment on Irving Street, SF Signal was fair but with severe multipath waves.
So indoor antennas on Irving street do not get NBC.
Carmel Street, San Francisco would be my pick for the absolute worst spot in San Francisco for OTA tv reception.
Try outdoor double- stacked VHF antennas just for NBC if you live on Carmel st.

I don't understand all those people saying they lost KNTV reception. It has not changed up here at all. They must have issues with their antennas.

I was thinking recently that since my current antenna configuration hasn't changed for a long time time how stable all the signals from all directions are. I see the same sort of ups and downs on all the stations. SNRs are little changed over the long term. Even the most marginal stations are unchanged. If I do see changes in the years to come it'll probably be from growing trees.

Probably. Most of them were yelping (whining) about poor reception without providing details about what they had or had not done. Of course, VHF indoors is a particular PITA and KNTV's location separate from everything else isn't helping most people in downtown SF.

I think people forget about the "scanning-in" process. So if the station sends bad data, nothing will show up on 11-1 and people never re-scan.
That, plus the failed campaign of nbc-3 branding creates a viewer mixed - up sloppy operation.
How many people dump cable, .... and still enter 3 on the tv for NBC ?

Reception issues .... have taken over their online reviews. No other tv station has that number or type of complaint.

Another station that has issues like this is 47 If I enter 47, after a few seconds the tv advances to 68-1
when they send bad or no data, it stays on 47-1
And it will flip-flop back and forth at any given time.

I agree with Chuck. Signals vary quite a bit, especially those that are some distance away from here, but it's always within established limits. I'm seldom surprised anymore by what I see. For example, stations like KMAX and KQCA from Walnut Grove can vary from just above the cliff edge, like 16 dB SNR, to as high as 26 dB, but they very seldom drop out or get pixelated. KVOR has a lower range, from 13 to 20 dB, but their signal is always within that range. VHF stations KVIE and KXTV are more often below the cliff edge at 13 to 14 dB than not, but they can make drastic increases to 20 to 22 dB at times. But again it's all within the established range of signal strength.

One station that doesn't vary much at all is KEMO, transmitting from Mt. St. Helena. It's usually between 20 and 22 dB all the time.

The distance for Walnut Grove vs Mt. St. Helena is very similar... 62 vs 65 miles... but the difference is the terrain. There are few hills between here and the Napa Valley, while Walnut Grove is on the other side of the 1,000 foot high East Bay hills. Is hilly terrain more conducive to inversions than flat terrain?

Every once in a while I see channels 20 and 24 that transmit from the bluffs east of Red Bluff, which is about 175 miles from here line of sight, but I have never received anything from the Salinas/Monterey area to the south.

Some fuel for conspiracy theorists: KNTV is NBC. Comcast owns NBC. Comcast is in the business selling cable service. OTA competes with cable service. I'll let you draw your own conclusions smile.gif

Is there a possibility that the connection between the antenna and the tuner has unnoticeably degraded over time (e.g. sun-bleached balun, animal chewed a cable, internal corrosion in a splitter, etc)? With a digital signal, marginal reception is indistinguishable from perfect reception when looking solely at the TV screen.

I've thought about this and I think the inversions are more helpful in some cases than others. If you were to move up hundreds of feet you might achieve LOS to Walnut Grove and signals would be very strong. An inversion at just the right height will bend those signals down to your antenna and greatly increase the signal strength. If you're at or close to LOS to KEMO then inversions may not do much to increase the signal since you already have a good signal with little terrain blocking.

The less the signal has to be bent the more often you'll see increased signals. I suspect that this is the case with me and Salinas. There's only one ridge between me and Fremont Peak and Mt. Toro and the bend angle is very shallow. It seems to take only the slightest inversion to make a big increase in those signals and signals hardly ever drop below their nominal levels. OTOH, inversions seem to only make the Walnut Grove signals go down. I rarely get significantly enhanced signals from Walnut Grove. Signals from Sutro seem to have about an equal amount of up and down and the range is small. The exception to this is KKPX on Mt. San Bruno which can rise from no signal at all to SNR 31 dB at times.

Everyone's situation is going to be different based on the terrain they're dealing with.

Thanks for the suggestion. I replaced the entire cable and balun all the way to the tuner. No splitter in between.

The graphic that he posted showed KGO with a 93% (strong) signal and 50% (low) signal quality. There are only two things I know of that can do that; 1) interference in the KGO frequency range or 2) multipath. Since it happened suddenly it sounds more like interference to me. Some new device came on that has a spurious emission on channel 7. Moving the antenna might actually be a good test. The attachment shows what an interfering signal can look like to a DTV station. It's not the best example but it shows a weak KRCB on RF 23 and interference from KMUV analog on Fremont Peak. The spike 1.25 MHz up from the bottom is the KMUV video carrier.

The problem neighborhoods are residential ......... The entire height-Ashbury district, parts of the marina & inner sunset,

Except when they're behind Mt Sutro. Mea culpa on the "downtown" reference, it wasn't at all precise.

Hi,

 

One more thing about inversions.

 

The San Francisco Bay has a moist marine layer above it most of the time.

 

From time to time this wet fog is replaced by drier air from inland which sometimes matches my periods of poor receiption for some stations.

 

The dry air of a few days ago has been replaced with wet air and KEMO at ~ 97 miles has improved from what it was yesterday and before.

 

I thought it might be the re-installation of my CM4228HD, but that appears to be false.
