I'm going to call them today and will post their comments when done.

Glad to hear I'm not the only one missing 5-1. Anyways, I'm in Little Elm and I get channel 27-1 with a constant 70% signal strength, no dropouts or anything. I'm using a Radio Shack 15-2185 antenna mounted in the attic.
post #63 of 7246
yea! I lost 5-1 last night too, it was just after the news. At the same time I was messing around with my antenna.... I thought that I messed something up and lost the signal. Glad to here that it wasn't something I did.
post #64 of 7246
Any news yet on what happened to 5-1? My wife was particularly annoyed to lose Law and Order, even more so to lose it to a replacement weather radar!!!
post #65 of 7246
My wife told me 5-1 is back on the air. Don't know what happened.

I noticed a number of you are in North Dallas. I just picked an HDTV and am trying to figure out how to get OTA HDTV. I am in McKinney and thinking of getting a CM 4228. Can this be mounted in an attic with good results. Also, any recommendations for a good installer in the area if I decide not to tackle myself?

TIA

I'm in McKinney also, Stonebridge Ranch, and have no trouble recieving all the HD OTA with my in attic antenna. 27 is the weakest channel.

I'm in SBR as well. What antenna / OTA receiver are you using? Do you have the antenna amplified?

Not sure what model it is but did find a Radio Shack emblem on it. It's an 8' and an amp has helped improve some of the signals but even without it I was getting everything. One oddity it that I lost 27 after adding the amp???
I'm using the LG LST-3100a and had a Samy SIR-T351 before with the same results although the Samy showed a stronger signal on it's meter.

Here's a D/FW forum you should check in addition to this one:

Is anyone in Plano or north Dallas using Comcast HD cable?
How is the signal? How is the picture quality on SD? What STB do you get from Comcast? Any information would be most helpful.
post #71 of 7246
I have HD with Comcast. I am in McKinney, was one of the early adopters and had my install last November. I would have to rate the service as very good from a quality view point. I did have some initial problems that were resolved when a Comcast tech changed a bunch of connectors, splitters in my cable wiring. HDTV seems to require that you have very good lines and connectors, especially if you have multiple TVs and hence splitters. Service has been great since then.

We get ABC, CBS, NBC FOX (480p widescreen), ESPNHD. Premium movie chanels available are SHO, HBO, STZ and MAX.

The audio for a lot of programming is 2 channel dolby surround. Do get full Dobly 5.1 on many ABC programs, some CBS and some movies.

Bottom line is I would recommend the service. Lack of HD channels is about the only downside right now.

The stb is the Mot DCT5100. They are adding DVR at the end February, which will be the Mot DCT 6204 (I think).

I noticed the picture on 8-1 was worse last night and then discovered that 8-2 is doing a lot more than just RADAR. I'll have to check exactly how much bandwidth is being wasted by that crap, but it's definitely affecting the quality of the main broadcast. It's bad enough that they convert ABC's 720p to 1080i. But don't they realize that 1080i takes more bandwidth to compress?

Just say "no" to simulcasting.

I have a 6200 box in Frisco and it's made me really love my Samsung. I actually watch a few shows now in HD just because of HD. I did have to get the first box replaced but that wasn't a big deal.

I should say that Comcast appears to be really bending over backwards to make it work. They may be clueless when you call, and the techs may not know everything, but they will send someone out any day and any time.

If you want it to work perfectly right away and all the time then you may not like it. If you're willing to live with some tweaking then it's great if you have a HD set. I suppose all HD programming is going to require tweaking so maybe it's not fair to blame Comcast.

Im located in Aubrey, right now im using Zenith silver sensor indoor antenna and picking up NBC, CBS, UPN, FOX, PBS and HDNET (HDNET only on weekends for whatever reason). Getting VOOM installed this weekend.

I posted this same issue on the DHTG forum, but since the new radar has been put up, my SOny HD300 is having problems with channel 8.1 and 8.2. The picture keeps breaking up and the audio is cracking. The signal reads well above "good" and hasn't changed. It is working fine on my HD200 downstairs. Does anyone have any thoughts? Thanks.
post #76 of 7246
I have a built-in HDTV tuner in my HDTV (Mistubishi WS-65511) and a MyHD. Neither seems to have problems with the two channels (other than the poorer quality).

post #77 of 7246
Greetings all. I'm new to the HDTV world, but I finally got a new TV (16:9 Samsung) and a STB (T351). I'm using an old Radio Shack antenna in my attic that I've had for over 12 years. I'm located in Watauga (NE Tarrant county) and I get good reception on all the DTV channels.

I've noticed that most of the stations will show black bars on the side when showing non-widescreen broadcasts, and others will use grey bars. Now, I assume grey bars are better for screen burn-in, and on my TV the only way I can get rid of them is to zoom the picture (and crop the top/bottom.) I guess this is something I'll have to live with until more wide screen programming becomes available? If I watch a lot of 4:3 stuff will my diurect-view CRT eventually burn in?

The other question is that on my T351 some 4:3 broadcasts that are not listed as being in HD (e.g. local news on Ch. 5, etc.) are being listed as "HD" when I hit the info button on the T351. Is there such a thing as HD that is in 4:3? The PQ looks good, but I'm not sure it is true HD..

Hi.

I really want to get a HDTV sometime this year. I live in an apartment.. I can't do DirecTV (no southern view), and the cable system is basic, analog cable. (repackaged by the apartment complex). This means my only source for HD programming would be OTA stuff. But that's fine, as I actually watch a lot of broadcast network stuff.

So, will a good *indoor* antenna work for me? I live in North Dallas, on Preston Rd. between Spring Valley and Belt Line.

@jsmeeker

Try the Silver Sensor. You will probably be able to get all but ABC with that. ABC is on VHS, but the SS is only for UHF. I'm not sure what to do about that.

Some general DFW DTV questions:

1. Why doesn't WB convert from physical 32 to virtual 33?
2. Why doesn't WB have a 3x-1? I see 3x-2, 3x-3, and 3x-4.
3. Why does WB's upconvert have checkerboard patterns in it?
4. Why doesn't KFWD convert from physical 51 to virtual 52?
5. Why doesn't KFWD have a 5x-1?
6. Could there be a worse MPEG encoder than KFWD uses?
7. Why can't I receive KDFI at all? I have no problems with the other channels, except KFWD, which is borderline.
8. What's up with the spanish channel (I think it's 48) that has major analog interference (I believe it's called "herringbone") on the DIGITAL signal?

Hmmm... ABC is VHF? I didn't know that. Could I get a indoor VHF antenna and use it in conjunction with a UHF antenna?

I really want to be 100% positive I can get all the major stations (ABC, NBC, CBS, FOX, WB, UPN) with an indoor antenna before I actually buy the TV and the STB.
post #81 of 7246
I believe indoor VHF antennas are just rabbit ears . If you can get a relatively static-free analog ABC (8) with that type of antenna, then I think it is very likely that you'll get the digital well too. But if there is lots of ghosting, which is caused by reflections of the signal off of buildings (no mountains in DFW), or if the picture is snowy, then you'll have problems. With my attic antenna east of Plano, analog 4 and 5 are very snowy and barely have color. 8 is watchable, and 11 and up are pretty decent (except all the religious and shopping stations, which obviously use a much lower power). I get all the digital channels on the same antenna very well. Only 52 is borderline, and I don't get 27 at all (I understand they use an extremely low power).

Also note, it is likely that most stations will move the digital signals from their current frequency to the analog frequencies once the changeover is complete. So more than just ABC may be VHF in a few years. They are probably going to increase their power by then as well.

post #82 of 7246
hmmm... Didn't think of that. I could try getting an antenna and try to pick up analog, NTSC stuff.
post #83 of 7246
Has anyone else been watching Channel 21-1 lately. Lots of programming in Hi-Def that is different then what is showing on HD-Net. Are these two channels affiliated. I have no idea what station it is but it sure looks good.
post #84 of 7246
Unless I'm mistaken, it is HD-Net from last year. I had an email address where you could get the weekly listing. I'll look an see if I can locate it for you.

post #85 of 7246
I was curious how much bandwidth is wasted by the simulcasting of the weather radar on several of our local affiliates, so I checked. Here is what I found (on the channels I can receive) as of April 2, 2004:

4 KDFW-DT FOX
_1 - 1280x720p 16:9 14.94 Mb/s

5 KXAS-DT NBC
_1 - 1920x1088i 16:9 14.9 Mb/s
_2 - 720x480i 4:3 2.44 Mb/s

8 WFAA-DT ABC
_1 - 1920x1080i 16:9 15.8 Mb/s
_2 - 704x480i 4:3 2.4 Mb/s

11 KTVT-DT CBS
_1 - 1920x1080i 16:9 18.9 Mb/s

13 KERA-HD PBS
_1 - 1920x1080i 16:9 14.5 Mb/s

21 KTXA-DT UPN
_1 - 1920x1080i 16:9 16.69 Mb/s
_2 - 704x480i 4:3 2.5 Mb/s

33 KDAF-DT WB
_1 - 1920x1088i 16:9 17 Mb/s
_2 - SAP ?? Mb/s

52 KFWD-DT IND
_1 - 704x480i 4:3 15 Mb/s

68 KPXD-DT PAX
_1 - 704x480i 4:3 15 Mb/s

So some notes:

1. About 2.5 Mb/s is the going rate for the weather radar.
1. FOX 4 is not using all of their bandwidth for their upconverted HD channel. What is in the other 4.46 Mb/s?
2. NBC 5 is using a very bad MPEG encoder to get such a crappy weather radar from 2.5 Mb/s.
3. What is in NBC 5's other 2.06 Mb/s?
4. ABC 8 could switch to 720p and fit comfortably in 15.8 Mb/s, although 1080i definitely suffers from the missing bandwidth.
5. It's good to know that ABC 8 isn't using more bandwidth than the other channels for that overadorned simulcast.
6. What is in ABC 8's other 1.2 Mb/s?
7. CBS 11 is using almost all of the 19.4 Mb/s. HOORAY FOR CBS 11!!!
8. What is in PBS 13's other 4.9 Mb/s?
9. UPN 21 is using almost all of their bandwidth for picture!
10. WB 33 has an SAP channel that is probably using up more bandwidth for the second audio channel. But even at 384 Kb/s, there is still 2 Mb/s missing.
11. 52 has extremely poor video quality for using 150% the bandwidth available to DVDs (and 300% of what a typical movie actually uses).
12. What is on 52 and 68's other 4.4 Mb/s?

I saw over on HDTV pub that WFAA is only using 18.6 kW right now for DTV...is that still the case? If so, does anyone know when they are planning on cranking it up a little?

I'm up in McKinney and that is the only channel I'm missing...everything else shows 85-90% with a pre amp one my sylvania tuner.
post #87 of 7246
WFAA comes in about the same strength east of Plano as the others, for me. But remember that WFAA is VHF, while the others are UHF. If your antenna is UHF-only, then you won't get a signal from WFAA.

Not sure if this is relevant, but the couple of times I have recorded HD programs off of KERA, they did have a secondary stream, it looked like SD. Guess when there is actually something on in HD, there would magically appear a 14-2 (or 13-2), they don't seem to be real consistent.
post #89 of 7246
I'm in a rental townhome apt that won't let me install ANYTHING outside (don't get me started...). In uptown Dallas, where there should be anywhere from 5-10 great channels, I can get one (Ch. 11) sometimes, if the wind is right & I stand in careful alignment, using a Silver Sensor. I tried one of the bar-shaped indoor Terks & it was worse. I'm now tempted to try the Winegard ss-1000. Anyone want to offer suggestions? Better than Silver Sensor, or should I just move?

Maybe there's some sort of metal wire I can just run all over my house to create a giant loop? Any ideas, anyone?

Sigh.

Thanks!

Do you have access to an attic? I have my antenna in my attic and I get very good reception east of Plano. I'm sure I'd get better reception with an outside antenna, but just like you have your landlord, I have my wife....
