At the nbc5i.com server (I don't want to bombard them with SPAM), you could try TVReception. I've also used engineering. On the nbc.com server, I've received responses from John.Sanderford and Jim.Borden (although not about their power drop).

Looks like the Channel Master Stealth Antenna (with amplifier) is about the same price as TERK 55 but it certainly is not nearly as stealthy looking as the TERK 55. Hum, going to have to think about how I can convince the wife (I know, PW-ed but that is why I have been marrried for 20 years)

I think its kuhl looking, just like the bomber! Works much better also. No amplifier needed for me, only 8 miles from Cedar Hill

Just wanted to let everyone know that I just got this reply to my email to NBC5i.com from yesterday commenting on the low signal strength some of us have been seeing:


I will check on the transmitter plant tomorrow as I will be at that site.
According to the control equipment, I am not seeing anything that would cause a drop in signal strength.
But I am doing my rounds at that site tomorrow and will make sure.
Thank you for contacting us.

John Sanderford
Transmitter Supervisor



At least they responded and are aware of the issue, which is something good.
post #155 of 7246
Interesting. Maybe he will find something. Tonight I'll play with my tuner and see if I can get 5.
post #156 of 7246
Count me among those who are puzzled by the loss of 5-1 signal strength. Since moving to HD in February I have consistently had good picture on 5-1 but since late July I'm unable to get a picture (the dreaded 'Searching for Signal' message on my Sammy HD-Directv receiver). FWIW, 4-1 has been very sporadic since before the MLB All Star game. Hope these problems clear up before the Olympics/football season.

I just counterposted essentially the same message at http://dhtg.napurano.com/ (Dallas Home Theatre Group) so if any news come from there I will redirect to this site.

I wonder if Mr. John Sanderford (Transmitter Supervisor) found anything wrong when he checked things out yesterday. Tried once again unsuccessfully to get NBC last night. Guess I'm going to have to breakdown and buy another antenna. The bummer part is I'm going to have to mount it in the back of the house next to my dishes because I don't want it showing in the front and make another 100' run of cable. That is why the Terk 55 was so perfect, very low profile. Oh well, if that is the worse thing that happens to me today, I'll survive somehow.

There is an interesting article in the August 2004 issue of Home Theater Magazine that I wanted to mention here. The title is called:

Terrestrial HDTV: Is it plug and play yet? (Page 42)

Here is his article on his webpage, but geared more toward the Square Shooter:

http://www.hdtvexpert.com/Pages/squareshot.htm

The writer, Peter Putnam,CTS, ISF, does an outdoor and indoor antenna test with antennas such as:

Winegard's Square Shooter-1000
Terk's TV55
Zenith's Silver Sensor
Channel Master's 3000A
Radio Shack's 15-1880
and homemade bow-tie antenna

Using the LG LST-3100A tuner

Test's included:

Indoors - Conducted in the writers studio in Doylestown, Pennsylvania about 22 miles from the Philadelphia transmitting towers over a partially obstructed path.

Outdoors - Moved out front to the parking lot and put them on a 5 foot tall mast at ground level

Results:

Indoors (DTV channels picked up) -

Winegard's Square Shooter-1000 (9 channels)
Terk's TV55 (6 stations)
Zenith's Silver Sensor (7 stations)
Channel Master's 3000A (7 stations)
Radio Shack's 15-1880 (10 channels)
Homemade and scrappile yagi antennas (9 stations)

Outdoors (DTV channels picked up) -

Winegard's Square Shooter-1000 (9 channels)
Terk's TV55 (8 stations)
Zenith's Silver Sensor (7 stations)
Channel Master's 3000A (not mentioned)
Radio Shack's 15-1880 (not mentioned)
Homemade and scrappile yagi antennas (not mentioned)


For more information on the tests, check out Peter's Website:

Here is more detail on the Wineguard SS-1000 (listed above):

post #159 of 7246
Thanks for the links. Interesting. Obviously the Winegard's Square Shooter-1000 is a superior antenna. Very boxy looking. Plus $150 for it. He was not too kind to the Terk55. Oh well, live and learn.

Well, This is what I have done...

I went ahead and picked up the Radio Shack DTV antenna. This antenna plus a second amplifier I'm able to pull in:

D02(43): KDTN-SD {54%, 15.9dB}
D04(35,36): KDFW-DT (Must reorient antenna element to receive viewable signal)
D05(41): KXAS-DT {91%, 24.8dB}
D09(9): WFAA-DT? {22%} Very poor signal, probably due to VHF
D11(19): KTVT-DT {98%,26.5dB}
D13(14): KERA-HD {74%,20.2dB}
D20(20): ? {23%,6.4dB} +
D21(18): UPN 21 {80%,21.8dB}
D23(24): KUVN-DT {81%,22.1dB}
D30(30): ? {42%,11.5}+
D33(32): KDAF-DT {100%,27.8dB}
D39(40): KXTX-DT {94%,25.6dB}
D45(45): ? {31%,8.5dB}+
D46(46): ? {65%, 17.6dB}
D48(48): ? {87%,23.5dB}
D51(51): KFWD {79%, 21.4dB}*
D68: KPXD-DT{85%, 23.0dB}

+ Station is too weak to get a video lock, sometime audio comes through, but rarely.

* Station does not seem to send an ID packet with signal, Call letters determined by on-screen station id overlay

>> Oddities: My receiver seems to pick up 2 D04's one with decent signal strength (35), one with very poor signal strength (36).

Not too bad for a piddly indoor antenna.

I set up the antenna to point out a window. The window is actually facing east, but according to antennaweb, all of the stations are SW of here, so I must be picking up the signal bounced from adjacent buildings. One of the challenges to using an indoor antenna in this complex is the fact that the buildings are artificial stucco.

On the cable end, it appears my tuner card (Fusion HDTV QAM) does not receive cable signals, due to the frequencies used by the channels. I now have the DVR receiver from Comcast, and can view HD programming, but the STB has to downconvert to 480i to get a picture on my SD TV...

One of these days I'll get the real deal
post #161 of 7246
I'm trying to find a way to record an ESPN-HD football game next month (and save it if my team pulls out a victory ;-) ). Obviously I can't record from satellite (which is what I have now), so cable is my only hope. However, they don't offer HD cable in my area yet.

I will be buying an additional ATSC tuner card for my HTPC (I already have a MyHD) to allow me to record two OTA programs at the same time. I'm most likely going with the QAM FusionHDTV card to give me the option of recording from cable, if they ever get it in my neighborhood. For the specific game next month, I was hoping that I might be able to find someone in the area with HD cable and tote my HTPC to their place just for the day (if all goes well, I'll actually be at the game myself).

But that may all be for naught....

Why do you think the cable frequencies are the issue? There are a number of other potential problems, including scrambling and QAM compatiblities. Did you get some error that indicated this? Can you access any HD channels on cable?

Based on information I've read on this forum, I have deduced that this is the issue. Apparently Comcast in my area uses HRC for their channels. This is usually indicated by the presence of both channels 5 and 6. Which, Comcast in plano uses. The fusion card's software only tunes normal CATV and OTA. These are also the only channels I can get over the cable wire (and poorly at best) no analog, no digital. I realised that QAM would be another issue, but there have been some positive reports, at least with QAM256. I've tried GotAllMedia, but it's very unstable and I can't seem to tune anything w/o crashing. GotAllMedia, if I can get it working might enable me to pick up cable signals, then I can do battle with QAM modulation.

I also realise that I cannot get the channels that are encrypted, but ESPNHD isn't supposed to be and the local channels shouldn't be.
post #163 of 7246
I'm watching Monday Night Football OTA and I am wondering if anybody else is having an issue with the Dolby sound? When Michaels and Madden are speaking it is only being broadcast thru my front middle speaker. The crowd noise and refs on the field are coming thru left and right front speakers and sound great. As soon as ABC goes to commercial the sound returns to normal. Because of this I really can't adjust the sound. I hope this is just a "dress rehearsal" issue that ABC will correct (and I really hope it is not an issue with my receiver!) Other than that, the picture is wonderful. Thanks - Art

@mraiford - I'm sorry, I must be dense. I still don't quite get what you are meaning. You mention the analog cable channel modulation scheme, but how does that relate to (H)DTV content on the cable? I'm not concerned with recording analog, only HD. Have you been able to record QAM with the Fusion? It looks like you are trying to use the Got All Media application to control the card. Does the Fusion software not support QAM, so you must use a 3rd party's s/w?

Hmmm... Now I'm beginning to wonder. The fusion software natively supports QAM(256 and 64). I thought the channel frequencies w/ QAM were the same as the analog channel frequencies, but used a different modulation than analog?
post #166 of 7246
I believe that QAM allows pairs of channels to fit into the 6 MHz slots used by one analog or ATSC signal. That's pretty much all I am aware of, and I don't know what the QAM 64/256 numbers mean, except that there is a difference that must be supported by the tuner.

post #167 of 7246
Two completely unrelated notes....

Quite by accident, I noticed that KDFI-DT (27-1 on physical channel 36) is now at a power which I can actually receive!!! I get about 58% on my MyHD card, which is about the same as I get with KXAS-DT (the other channels are usually better than 85%). My Mitsubishi 65511 (which has a bit more sensitive tuner) also has no trouble with the channel now. Just in time to watch the Rangers plummet out of the division race :-(

And it looks like KXAS has removed the radar loop on 5-2. I'm not exactly sure what they are doing. It looks like 5-2 is actually gone right now. I didn't have time to look closely last night, including checking the bitrates. But I'm wondering if they are preparing for the Olympics. My understanding is that the HD broadcast will be delayed one day, and for the duration of the Olympics will be an 8-hour repeating loop that does not include their analog broadcast. So I'm guessing they may intend to put their analog broadcast on 5-2 for the duration.

Glad to look thru this thread, I have constant problems locking into NBC, it seems the signal is strong till about 10 PM and then drops out. Im located in Providence Village (about 6 miles South of Aubrey) and have a Winegard installed on my roof. I am at wits end on what to do next, I will tune NBC so Im receiving a 90 signal and then on occasion it flucuated from 30-80 with the dreaded Signal not Found showing. Has anybody figured out what is going on, have you upgraded your antenna to elimate this problem and if so please share. Im just glad VOOM added 3 stations (1-HD 2-SD) on their satellite so I can watch the Olympics, but Id like to get this problem fixed before the fall season starts. Im tired of having to watch NBC on my other tv via crappy cable SD. Thanks.
post #169 of 7246
Hey SMT, well good luck! I live in Rockwall and I can't get NBC HD period. Every one else of the HD channels come in like champs but not NBC. I assume their tower is located in Cedar Hill so what is the deal? Don't know. I wish NBC would think a little out of the box and realize there is an issue they need to investigate or come out and be honest if they are doing something like directional antennas. There is no reason why "peripheral" cities (like Rockwall or Providence Village) can't get the signal but the Plano's and Richardson's can. Oh well, fortunately there not much on NBC anyway so I guess I really won’t miss out on much.

Xesdeeni

I couldn't tune KDFI-DT (27-1) at all last night. But a couple of nights ago I could swear that it was coming in pretty strong. I can receive most OTA via my attic antenna with signal strengths in the 80's. KDFI-DT has always been the exception, with a stength as low as the 30's at times.

Does anyone know if they are indeed preparing to increase their power (and are going thru growing pains in the process) ?? I can't record the analog channel with my PVR, so I need the digital broadcasts by October - if hockey season arrives anyway...

BTW- did anybody catch Star Trek IV in HD on UPN (21-1) last night? This must be the deal with Paramount (one movie aired twice a month in HD). But the listsings in titantv and the Tivo guide did not show it as being in HD. I'll have to find some way to remind myself about The Godfather I+II in November.

post #173 of 7246
No, I missed ST-IV last night, because there was no information that it would be shown. However I have discovered that it will apparently be shown again on Sunday August 29, at 10:30 PM.

post #174 of 7246
I've had problems getting NBC in, for the last week Ive been getting a signal of 90+ with no dropouts, anybody else notice the improvement?
post #175 of 7246
As a matter of fact I was able to get NBC 5.1 for the first time on Sunday afternoon (8-22-04). I have been meaning to post my pleasant surprise. Now it is a bit flaky and I usually have to up/down channel several times with my E* 811 until it locks in (usually settles around 74%). I wonder if NBC made any changes? Now if they could boost the power just a tad bit more and revamp their "content".... Regardless, good move NBC.
post #176 of 7246
I just wish they'd upgrade their MPEG encoder. It's horrible. I haven't verified the bitrate, but they removed the radar sub-channel just before the Olympics, and I assume this was done to increase the bitrate for the HD feed. But the quality of the encoding is still horrible. Some of the electronics stores are running the NBC HD Olympics on all their HD sets. I wonder how many sales that crappy macro-blocking is costing them.

Xesdeeni
post #177 of 7246
I completely agree about the MPEG encoder. It was probably one they bought off of EBay. My wave of enthusiasm took a bit of a hit last night. It took me about 15 tries before I was able to lock 5.1 in (looked like around 73%). About 10 minutes later it lost lock and I could not get it back. I finally gave up and went to 148 and watched it thru E*. Very disheartening. Perhaps the new software upload from E* (for my 811) might help the situation (though it seems that the latest upgrade is not intended to do anything for OTA issues.) Dang it!
post #178 of 7246
I had no problems last night with NBC, was locked in all night....
post #179 of 7246
Hey SNT, is Provenience Village located north of Denton? That is quite a distance from Cedar Hill if that is the case. Did anyone ever determine if NBC was using a directional antenna instead of an omni to broadcast the HD signal? I'm trying to figure out why I'm having heck of a time getting NBC. Thanks - Art
post #180 of 7246
Im not North of Denton, Im located 10 miles East of City of Denton right off 380.
I think Im about 48 miles from the station. Just rotating my antenna and
1" or 2 will loose the station.
