For reference, here is a list of the Tijuana Digitals as well as other channels in the area that may cause co-channel inteference in receiving these (generally Los Angeles stations). So basically there are co-channels issues for all of these. Wish the FCC would fix this and not assign the same frequencies in Los Angeles, San Diego, and with Mexico/TJ.
CURRENT
6-1 XETV-DT 23 Mt. San Antonio
Co-channel interference with KTBN-DT. Relocating in the future maybe 6/12/09???
12-1 XEWT-DT 32 Mt. San Antonio
Co-channel interference with KDOC-DT.
28-1 XHJK-DT 28 Mt. San Antonio
Co-channel interferece with KCET analog 28. Future co-channel interference with KCET-DT.
29-1 XHTIT-DT 29
Co-channel interference with KFTR-DT.
Also co-channels with analog KSDX-LP, planning to go to digital on VHF 9 sometime in the future (thanks Michael).
57-1 XHUAA-DT 22 Mt. San Antonio
Co-channel interference with KWHY analog 22. Future - should shut down analog by 6/12/09. (thanks Michael)
FUTURE
33-1 XHAS-DT 34
Co-channel interference with KMEX analog 34. Future co-channel inteference with KMEX-DT.
Was transmitting for a couple of days, still needs permit to transmit.
38-1 XHTJB-TD 38 Cerro Colorado (thanks Hector)
Co-channel interference with KPXN-DT.
44-1 or 45-1 XHBJ tentative 44 (thanks Hector)
Co-channel interference with KXLA. Future - moving to 51.
49-1 or 47-1 XHDTV 47 Cerro Bola (thanks Hector)
Co-channel interference with KAZA-DT
Please let me know if anything here is incorrect.

XHTIT-DT also cochannels with KSDX-LP. KSDX is working on going digital on CH. 9. Who knows when KSDX-LD will sign on though. LD is the suffix for Low Power DTV.

BTW, name of this topic is bad since all of these transmitters are not on Mt. San Antonio. Should be 'Tijuana Digital Channels'.

KWHY-DT will stay on CH. 42 pre and post transition. Right now KWHY-TV is cochanneling with XHUAA-TD/DT but that will change once KWHY abandons it's analog signal so it won't co channel with XHUAA-TD/DT.

Andy:
About XHTJB-DT, the only thing that we know at the moment is the ch. allocation by the FCC, the coordinates that they have on that info are located at the top of Cerro Colorado, that´s where Once tv is broadcasting. In the mean time you can refer it as a "future" DT station. We´ll see if ch 38 will be the final allocation for XHTJB-DT when that info is released by SCT.
And don´t forget to add the future DT outlet for XHDTV 49 on channel 47 that will co-channel with KAZA-DT in L.A. As we know it, it broadcasts on top of Cerro Bola in Tecate, B.C. (Valle de las Palmas)
Oh, i forgot to add XHBJ 45 which the tentative DT channel is 44.

Is Valle de las Palmas close to Espuela? I believe Cerro Bola is right by Espuela in the Tecate municipality.

Actually no. That was one of their possible frequencies. It will probably be a subchannel of XHAS. They changed their plans. A DT mounted on top of Cerro Bola would have gotten very good reception in your location. It can even interfere with KAZA-DT in southern parts of Temecula. Thats how far it can go assuming 1000 kw.

If anyone is using Windows Media Center - could you please post in this thread at The Green Button? Microsoft does not want to provide program guide data for three of the channels broadcasting from Tijuana. The guide data is available to them from zap2it but they are being stubborn in not wanting to add the guide info since the stations are in Mexico. But they have the guide data available for several other stations broadcasting from Mexico.
Maybe if someone else would post that they need this guide data also, Microsoft would consider adding it.
Here is the thread at The Green Button - The Green Button site is for discussion of Windows Media Center issues.

Andy:
Good news regarding of Televisa´s DT channels, in another foum i´ve got news from a user who also lives in Playas de Tijuana that he talked via phone with an engineer of Televisa and told him that they started to test the new antenna arrangement (the one installed at the top of the VHF tower during last year and has elements on their four sides, or faces). So, i guess it´s a matter of time that they will use them permanently and finally you can receive their signals.
That user told on that forum that he was able to get both XEWT and XHUAA DT´s during last week, and i will tell you that last thursday, at the time when Mexico vs Italia soccer game was been broadcasted i still had a lot of problems to get XHUAA-DT but, latter in the afternoon , i was able to get a stable signal and watch that channel for a while and i didn´t have any problems receiving it.
In the evening i´ve checked the signal strenght on my HDTV box and it had a full signal strengh, meaning that they´ve improved or raised their transmitter power (that´s my guess).
Last Friday morning (early hours) XHUAA and XEWT DT´s were off the air for a long time, so i believe that the engineers were doing some work or maintenance with their transmitters, who knows.
So, stay tuned for your reception of these channels in the upcoming days. The engineer told the guy who lives in your community that these signals will cover that area once the testing phase is complete. |

At this moment. XHUAA and XEWT DT´s are broadcasting 1 sub channel each.
I rescanned my HDTV set and tuner box and now i receive XEQ-9 Galavisión on 22-2 and, the regular programming of XEWT on 32-2.
Both channels are not displaying their virtual analog channels. Must be part of the tests that Televisa are doing with these two signals. |

Héctor,
Thanks for the updated information. I will try to tune these digital channels and report back if I can receive them.
What broadcast frequencies are 22-2 and 32-2 on - both UHF 22?

FINALLY. Yes, both 12-1 and 57-1 look great. I knew my previous reception problems were on the transmission side. So the question is, why did it take Televisa a year to turn up the new transmitter after they had it installed? I know that some things take a long time in Mexico, but that is really long 
I can't get SNR readings on these channels since I no longer have the Toshiba LCD that provided that info...
Now if we can just get Azteca to get 28-1 and 29-1 'fixed'. Maybe one day.

I believe that they waited so long because they needed an authorization by the federal authorities (Cofetel or SCT) to turn on the new transmitters or modified radiation patterns (like using the new DT antenna arrays that were installed last year).
Good for you that you are able to get these channels. As for Azteca DT´s, in the other forum, the guy who also lives in Playas said that the reception of both 28-1 and 29-1 are fine, between 90 and 100% of signal strengh. I don´t know how far from you he lives.
If you like to contact him to change impressions, visit this thread: http://www.avsforum.com/avs-vb/showthread.php?t=878152&highlight=Televisa&page=1 9 he´s Paco 1986, i´m also posting on that thread. |

I imagine alot of people also can't get those channels, but not because of a weak signal. I have a RCA DTA800B1 box, but I think Azteca has messed up their PSIP since I was receiving it before. Now there's no audio or video but the signal level reads good. Walmart sold alot of those boxes at their Otay Mesa store.
Fortunately, my other CECB's do work with these stations.

nothing broken about transmission of 28 and 29 (though that's not the PSIP) unless they're simply not aiming your way. It's 36.1, 36.2 & 36.13 that seem to have real flaky transmission. Fine signal sometimes, then acts like they turned off the transmitter for the day.
Oh and I'm also getting good audio now on 12 and 57, just only on the SD and not on HD. strange. |

Correct, if you live in San Diego (esp. South San Diego) likely 28-1 and 29-1 come in great. The specific problem from me in my area, Coastal TJ, is that the digital channels broadcasting in TJ have been weak due to them not optimizing their transmitters to send enough signal in this direction. As Héctor previously posted, several of the stations didn't even have elements facing to the west.
Telemundo was the first to get it right when they turned up 34-1. Now Televisa has corrected this in 12-1 and 57-1. The only two remaining TJ digital channels that need to get this corrected for the reception in my community are Azteca 28-1 and 29-1.
I do get 28-1 and 29-1 sometimes, but other times I can't receive them. Not reliable enough to schedule shows to record. Their analogs are perfect in my area.
The transition to digital in TJ is still a work in process. So hopefully Azteca will get this improved in the future. I keep posting about this hoping that their engineers will come across these postings, understand that there is an issue with their radiation pattern with residents in sections of the city that they are trying to cover (Tijuana), and get it corrected.
Héctor - I'll take a look at the avsforum posing you referred to - thanks. |

XHTIT appears to now have a subchannel, 29-2 "$ futbol". They don't have any audio and the screen is black but the signal is just as strong as the base channel. Some time ago I posted some info about the Azteca subchannels being scrambled in Mexico City either in this forum or avsforum. Hope they don't do that here.
Perhaps more important, this is the first time I have seen a Mexican network with digital guide data (on 29-1). It extends for about 2 days but instead of regular text like in the US, it's all in CAPITAL letters. Hope they fix that and also that Televisa gets their guide up.

In fact, that´s not the first time that i have seen a digital tv guide on Tv Azteca.
Back in 2006 or early 2007 (when Azteca 7 HD programming was different of their analog ch. 21 XHTIT it had their guide but the local time was not syncronized with our local time.
Now, fortunately, their digital program guide is displayed in our local time. Way to go Tv Azteca. The program guide is available on both XHJK 28-1 and XHTIT 29-1
I hope that they synchronize their virtual channels to 21-1 and 27-1 again soon. |

12-1 and 57-1 have been weak again for the past several days. In fact I am unable to get 12-1 any more. It seems that they switched back to the old transmitter - could that be possible? |

Hi guys:
Paco, you must be the same Paco from the AVS forum. I´m Nightwalker1973 from that site.
Andy, Paco must be the person that i was talking to you the other day when i told you that he also lives in Playas. I hope that you can interchange impressions about these issues.
Yeah, i have the same old problems with the reception of XHUAA-DT again. You must be right Paco, seems that they´re using the old transmitters again, for now.
Thanks Andy for your feedback on the CM 4221 UHF antenna. I will try this model and see how long lasts mounted on my rooftop mast. |

Andy,
I think the problem is weather conditions causing LA stations to interfere with SD and TJ. Last night I was receiving all sort of LA market stations with an indoor antenna from Clairemont. XEWT RF32 is usually the first one to drop since its co-channel with KDOC and adjacent to KTLA RF31. |

Jesús:
You are able to get the Televisa DT´s because they´re broadcasting again (at the moment) with their old antenna arrangement located at the top of the UHF tower and has most antenna elements (16) on the north face; (towards San Diego) and 14 on the east face (Tijuana east). It only has 2 elements on the south face (that´s where i´m located); and 0 (none, nada) on the west (towards Playas de Tijuana). That´s the main reason why people like Andy and Paco who live on the coast of Tj can´t get these signals.
Also, XETV-DT is the most powerful of their combined (3) signals, being XEWT-DT the second in power and XHUAA-DT the least powerful channel. I believe that´s the reason why i have problems with my reception of XHUAA-DT (being the least powerful and located in the south side of Mt. San Antonio with only 2 elements to get their 3 combined signals). Reception of 6-1 and 12-1 (32-4), 12-2 (32-6) are ok. |

Hi:
As i already mention it on my comment #82 on the KFMB, KGTV-DT´s thread, i´m here to comment with my reception of the UHF channels with my CM-4221 HD antenna.
I placed my CM-4221 facing towards Mount San Antonio, the same direction that i had with my old antenna (a B2M mexican model), and checked my reception on my Vizio Tv.
Most of the UHF channels are coming fine, except for KUSI and KSWB-DT´s. These two suffer multiple pixelations at anytime (maybe because of weak signal, i don´t know) but, the funny part is that i have a line of sight with Mount San Miguel and i had no problems with the reception of KPBS and KNSD-DT´s since it´s installation on august 11. Also, i have a good reception of low power analog channel 69 (Milenio Tv).
According to wikipedia, the Mount San Miguel stations have the following in ERP:
KPBS-DT 350 kW
KNSD-DT 370 kW
KUSI-DT 355 kW
KSWB-DT 322.8 kW
About analog channel 69, wikipedia says that it´s the old ch. 61 (K61GH) and has an ERP of 2.95 kW. I don´t know if this information is accurate, because it´s ERP is way too low to reach my area, in my opinion.
I´m wondering why i have these issues with these (already mentioned) two digital channels. Maybe they´re broadcasting at the moment with a lower ERP (problems with their transmitter to broadcast at full authorized ERP). Maybe it´s their radiation pattern. Who knows.
I´m planning to move my CM-4221 a little bit towards Mount San Miguel (at an intermediate point between Mount San Antonio and San Miguel) and see if this improves a lot. Since i have Mount San Antonio a lot closer, i don´t think that my reception of the UHF channels will suffer much, but i´m concerned a bit more with one channel in particular: XHBJ-TV 45. I don´t know why, but i´m getting a ghosty picture (but watchable) in comparison with the other analog channels coming from the same spot. If i pointed away from Mount San Antonio, maybe i will get a worse picture, but i gotta try if i want to get all of the channels available in my area.
That´s the fact until now. Any ideas of my issues with the reception of KUSI and KSWB-DT´s?
Here´s a picture of my new antennas: YA-1713 high band VHF, and CM-4221 UHF.

Looks like the antennas are too close. The lowest frequency of interest (Ch 8) is the determining factor for the separation between the two antennas. In this case the half-wavelength of Ch 8 is 33 inches.
If you use seaparate UHF and VHF antennas I recommend you use separate coax lines to a conveniently accessable place where you can do some testing. Otherwise it's hard to reach conclusions.

Héctor,
I think JoeM is onto something. The antenna's appear to be too closely spaced. Lower the YA-1713 so you have 3-4 feet (or more) in between the bottom of the CM-4221 and the YA-1713. This could be causing the reception issues on KFMB, KUSI, and KSWB.
I have my YA-1713 at least 4 feet lower than my UHF antenna. Hopefully the guy wires will not be in the way. Be careful that the guy wires do not touch the antenna. You can use some electrical tape on the guy wires near the antenna if needed.
Also, it looks like you may be able to tighten up the guy wires. You may need to invest in some turnbuckles (you can get them at Willy's electronics, or most home improvement stores). |

Why the mounting angle on the UHF antenna?? Have you tried it in proper orientation with completely vertical back screen?

Hey Héctor,
Did you notice these new sub-channels of TV Azteca? I am only getting audio, but no video. Do you know what these are?
I also just noticed that 33-1 is finally broadcasting in HD, it was about time!

Paco,
How is your reception of the Azteca digital channels here in Playas de Tijuana? I am finding 21-1 and 27-1 very weak at my location. Most of the time we have to watch the analogs.
And yes, it is about time that Telemundo 33-1 has some HD content ! |

Hi guys:
Recently i´ve move my UHF antenna a little bit more towards Mt. San Miguel and checked the reception of KUSI and KSWB and my signal strengh improved.
I will leave them that way for the moment, until i can buy some more coaxial cable and terminals to relocate one of the antennas.
I have two options in mind:
1.- Relocate my YA-1713 up to the middle of the mast so it wont touch the guy wires and doesn´t get in the way.
2.- Relocate my CM 4221 to the reccomended separation (4 feet), or even up in the middle of the mast. What do you think?
As i mentioned before, the reception of analog ch. 45 is worse, sometimes the video signal distorts a little. The rest of the analogs are fine. And channel 69 (Milenio Tv) is coming great.
Paco, these new signals from Tv Azteca are channels that are only available for the HI-tv converter box. Man, i really don´t know why Tv Azteca is doing this. When i first heard of HI-tv, i though that they were simple converter boxes that can get all ATSC digital signals because they announced that it´s free OVA tv.
I initially thought that anybody who has an HDTV or digital ATSC converter boxes can get these signals but, oh crap!! they´re broadcasting these signals off the A/53 ATSC standards, meaning that anyone who wants to get these signals must get the HI-tv converter box and antenna for the "reasonable" price of $2000 pesos (according to their website). And, i heard in varios websites and opinions from journalists and/or analists that Tv Azteca is violating the federal communication laws offering other signals (besides their analog counterpart) withouth authorization of SCT of Cofetel.
I will check XHAS-DT 33-1 when i´m home to see the 1080i signal.
Thank you guys for your reccomendations.
Oh, by the way (i almost forgot). I´ve watched the Presidential address this morning and Felipe Calderón make a decree that the digital conversion and/or analog shutdown will occur between 2011 and 2015 throughout all Mexico. You can check the presidential address on this url: http://www.youtube.com/watch?v=bL1EEjRD21w between minute 22 and 26.

Héctor,
It is generally recommended that the VHF antenna be mounted below the UHF antenna. So it seems that your best option will be to lower the YA-1713 at least 4 feet below the bottom of the CM-4221. The CM-4221 can stay where it is.
So I believe this is what you are thinking to do with option # 1 in your post.
Something similar to this (but with the CM-4221 at the top vs. the Clearstream 4): http://hdtv.forsandiego.com/messages/1/7376.jpg
By the way, per the TV Fool site, how many degrees apart are Mt. San Antonio vs. Mt. San Miguel at your location? It's also possible that the issue with your UHF reception may be related to the antenna being aimed to far towards Mt. San Antonio vs. Mt. San Miguel. I know that you are already aware of this and have made an adjustment. But it would be interesting to see the difference in degrees to compare to the beamwidth specifications of the antenna.
The UHF aiming would not affect your VHF reception. Likely that is related to the antenna spacing as already suggested.

Apparently, those Hi-tv channels are broadcasting in MPEG4, which is the reason we can't see them.

Andy,
On my TV, Azteca 13 HD is 28-1 and Azteca 7 HD is 29-1. Both are coming in just fine at 92% signal strength.
And Héctor, thanks for the info. Wow, $2000 pesos for the Hi-tv converter box! Too much money!! |

I posted some info on HI-TV back in January. Azteca is just trying to cut in on some of the offerings of Sky satellite service. For a one time box purchase of $200 (I think) it doesn't seem like too bad of a deal if you're paying for Sky now and like the (encrypted) channels Azteca is offering. I haven't heard of any reaction from Televisa but then I haven't kept up with these developments since January.

I took a quick look and here's what I see. I'm not familiar with some of the channel/network designations:
28-2 $ AYM Sports?
28-5 $ FRISBEE Kid stuff
28-6 $ AZT 13- Delayed 28-1 ?
29-2 $ TVMEX General Entertainment
29-3 $ PMANIA Movies ?
29-4 $ NTN News
29-5 $ AZT Soap Operas
Didn't notice if any were HD, but with that many subchannels I doubt it.
Some CECB's can get the main channels (28.1 and 29.1) but not the the subchannels at all.

H.264 (MPEG4) encoded channels are probably in the new, more robust,
ATSC-M/H format. Mobile-DTV-Viewer software runs under WINDOWS:
http://www.mobile-dtv-viewer.com/
A variety of tuners are compatible with ATSC-M/H...and some aren't:
http://www.avsforum.com/avs-vb/showthread.php?p=19106323
If you don't see video for one of these sub-channels, it might
be an audio-only sub-channel.....

Thanks Paco. I'll have to check my antenna orientation. I'll also need to check if I can receive these channels with 1 antenna now vs. 2 combined. With the improvements on the transmission side for Televisa, maybe I no longer need the two combined Channel Master CM-4221HD's.

If someone was able to receive them in TSReader, then they're not in ATSC-MH. TSReader does not support ATSC-MH streams at this time.

TSReader shows that capacity is being allocated to various
program streams, but doesn't label & can't decode them (yet):
Pgm5 = 1.59 Mbps, Pgm7 = 1.14 Mbps & Pgm10=1.64 Mbps:

Do you know if any usb tuner would work to view these hi-tv channels? Or does it have to be a specific type? |

Paco,
I have a FusionHDTV5 lite pci card and a HVR-950 usb tuner. Both work with linux. For Windows decontv's software worked with both as well. As the article below mentions to make sure you install VLC when prompted even if you have it installed already. The bottom line is that if you already have a pc tuner you might just need the proper software to view the newer formats.

Someone here recommends a Kworld PlusTV PCI card and BlazeDTV 3.5 software.

I will lower my YA-1713 as suggested some time latter when i have the neccesary money to buy the extras that i need to do that.
By the way, last Friday i re-scanned my Vizio Tv and "voilá" i was able to get KDTF-LD channels (my UHF antenna is oriented approximately at mount San Miguel). I noticed that these channels are very weak and, most of the time (during last weekend) i get them with pixelations, my Samsung HDTV box doesn´t get them at all.
Does anyone know their current ERP and radiaton beam (coverage area) of KDTF-LD on RF 51? I´d like to know if i can make some adjustments if there´s a possibility to improve my reception.
Well, i don´t really know how many degrees of separation is with Mount San Antonio vs San Miguel, but let me post this so you get an idea about my reception of all available channels in my area. Good luck with your movements on your antennas to get Tv Azteca digitals.

Hector, your tvfool chart appears to show just the digital channels. If you put chart the chart that has both analog and digital channels on it we'll be able to tell how much separation there is.
P.S. Delete the digital one to save space. |
