You know, I don't think I've seen true HD on WTVI anyway. Every time I check it out, it's really just a zoomed in SD image to try to fill your 16:9 screen. But "try" is the active word here, because you still see tiny slivers of black on each side, and the bottom of any graphics are cut off. Not to mention the quality of the image is crap. It may say "1080i" on the signal you get, but the source material is just zoomed in SD. The only PBS HD I've seen is from WUNG, and they only broadcast (OTA, at least) from 8:00 PM to 11:00 PM.

Digital Television, I guess. They make-up those names, and there doesn't seem to be a standard (some networks use a dash, others don't). For CBS, titantv.com is usually accurate, but Charles is right that decisions at the local station can mean you see a red "HD" on titan and you get SD on your set.

from the antennaweb site i got a 'red' for channel 23. is that good or bad?

Yellow would be better. Red, for me, means on the roof to get a signal through thick and thin. Jumping around, again for me, usually means interferance, multipath, or possibly overdriving your receiver. I don't know about the specific antenna you bought, but if it handles both VHF and UHF that means it's picking up and amplifying the FM band. If it has an FM trap, make sure it's active. If interferance is from other TV stations or multipath, and you don't want to buy more hardware, you just need to try more positions. You might need to do something drastic (how much coax did you get?). If you are overdriving (how many dB is the amp on that antenna, and what's it's noise rating), then you might attenuate. If you have a long length of coax, that would act as an attenuator, and you'd be ready to climb if it didn't work! It might seem like I plug Radio Shack a lot, but that and Slayton Electronics are the only local places I go for geek stuff. Anyway, they (RS) have a UHF-only yagi for $20 (a yagi is highly directional, so if interferance is a problem, it will have to be UHF interferance from Kings Mountain, or something between you and Kings Mountain). Good luck!!

I've just 'found' the whole AVS Forum, and now this thread. This is Great! I live in Statesville, have plasma HDTV, DirecTV, and an outside Radio Shack directional antenna/rotor. I have problems with WBTV-DT signal dropping. Most of the other CLT channels are ok most of the time. WBTV signal is really crazy...when I get it, I get it at 100%...then it goes to 0 (searching for signal).

I could use some suggestions on maybe replacing that antenna with a 'bow-tie' version (would I need to keep the rotor?).

Also, interesting about Adelphia, because if they come with that, I'll sign up with them (again). I do have their cable modem service here at home (cannot get BellSouth DSL here).

Any suggestions are appreciated...and thanks to all of you for creating and following/sharing on this thread.

Welcome! According to antennaweb.org, WBTV-DT should be one of your easiest stations to pick-up (from the south-west). It might be overdriving your receiver, so you might consider an attenuator as a first try (they are cheap). The bow-tie type of antenna is less directional so wouldn't help if the problem was interferance. I'd keep the rotor, if only to simplify optimizing the direction of whatever antenna you have. It seems like most stores sell combination UHF/VHF antennas, but all digital stations except WTVI are UHF. I wonder if those long upper or lower band VHF or FM waves are the source of some interferance. Maybe a harmonic or something. Just a wild guess, though. Also, I suggested to Charles, if you have any amplifier, engage the FM trap, if there's on on there.

These were just places where the whole screen went suddenly black, and no sound, then suddenly full picture again with sound.

Enterprise had a few blank spots so far tonight as well. This time I'm watching it live.

There's been at least 6 dropouts so far (8:45). There was a even short one during a commercial. It sure sucks when there's some action going on. Is this a local thing, or is it on the network feed?

post #66 of 7653
I've noticed the dropouts also. I've seen them on two different STB's. I first noticed them back in December during the James Bond movies.

Would it be too cynical to think that someone at UPN doesn't want to allow a 'perfect copy' of one of these shows to escape?

Was it just me, or was WTVI's digital signal missing yesterday? It's fine right now, but yesterday I didn't get anything.

--Dale--

It appears to be missing again.

Anybody else seeing "jerky" video on WCCB-DT? Signal strength appears normal and audio sounds OK. I first noticed it last night.

post #70 of 7653
I just flipped on WCCB and yeah its choppy. Audio is fine but picture is dropping tons of frames. Dunno whats up. What's your setup? Using a myHD mdp-100 here. It'd be nice to elimate it as a hardware problem.
post #71 of 7653
Thanks cmjman. I'm using a Zenith HDV420. Maybe Bob of WCCB will see our posts.

Yes, we're aware of it, we are testing some equipment configurations and will have another look at it today.

Has anyone else notice anything wrong with physical 44 OTA (WUNG 58)?

I noticed that the TitanTV schedule sometimes has 5 programs concurrently, with one being an HD program. I think that's not possible, and in fact when I played back several recordings of this station, there was a black screen where there was supposed to be a show.

But beyond having bad schedule information, I think the transport stream format is bad, or at minimum, confuses my tuner (MyHD 100). I usually don't watch live TV much, so my experience is with recordings. I can switch between subchannel 1, 3, 4, 5. Each has a show on, no problem. But when I try to switch to subchannel 2, it causes MyHD to crash. Actually, using the remote, it just quits responding. Using the subchannel button on the control panel is when it crashes.

But I wondered if anyone else has seen this strangeness with the PBS signal.

post #74 of 7653
I haven't had any problems, but I don't look at WUNG daily either. A lot
of tuners don't like the change in stream configurations that the PBS stations do when switching between HD & SD or all SD..

What's up with WCCB 18-1 Fox? Have they stopped broadcasting HD signals. That's two episodes of "24" in SD....Accckkkkk.

I usually record Enterprise (the Wednesday version), and they've been in HD. I had a really whacked Simpsons (wouldn't play with MyHD but would with VLC - and was fuzzy), but that was a while back.

Hello Charlotte peoples!
I'm having trouble getting NBC 6 the last couple weeks. It works fine for a few seconds, stutters , freezes, goes to black then starts this all over again. All the other stations in the area work fine. Is NBC doing something funky or is it my old Samsung SIR-T150?
Thanks
post #78 of 7653
I've watched NBC6 OTA fairly regularly of late (Law & Order SVU, Frasier, ER) and everything has come in well for me. I'm in Charlotte near the Southpark area. Have you had good reception in the past but only recently have gotten the drop-outs? Where's your antenna?

alexaaa, NBC has been consistent for me - flipping between 87% and 93% on the MyHD tuner at the moment (this is typical for my setup). I noticed that as the leaves came-out, and especially if it was raining or had rained recently, my percentages were down or were more erratic. Could it be there's something between you and the tower? Have you noticed any correlation with weather?

post #80 of 7653
I had been getting NBC 6 with no problems since I got my TV last year. I'm 30 or 40 miles SW of Charlotte. I've got a 4 bay UHF antenna 40 feet in the air. Must be my reciever or something, the amp maybe? Thanks for helping me figure out it's time to try something different.

Never was HD, but it's been ED widescreen fine all season - including the last two weeks.
post #82 of 7653
I started checking everything from the top. And that's where I found the problem. One of the connectors from the cable to the antenna had come loose. Once tightened down everything was back to normal. NBC was back!
Thanks for the help.
post #83 of 7653
Maybe I'm the only one who watches this show any more, but did any one else get a loss of signal at one of the climactic moments of last night's HD broadcast of Star Trek: Enterprise last night? This show is finally getting good (finally, after three years), and looks wonderful in HD, and at around 8:40 last night the signal went black for the rest of the show! My other local Charlotte channels came in fine OTA, and WJZY was back at 9 with their digital (though SD) signal. Just want to make sure it wasn't me.
post #84 of 7653
It wasn't just you. I posted this on the "general" Charlotte thread but nobody responded, so I figured I must have been the only one trying to watch Enterprise on WJZY's digital side! (This applies to the TWC folks too, since TWC just picks up the OTA digital feed and inserts it into their system.) Usually, when there's an outage like that, you have a whole host of folks screaming about it....

Would be nice to hear from an engineer involved to give an explanation as to what caused this, and whether Enterprise will be re-broadcast in HD this Saturday so we can catch up on what we missed because of the outage.
post #85 of 7653
Archiguy,

I found out that the tower was knocked out by an isolated T-storm in the area. They got it back up pretty quickly, considering (20 mins.), but too late to catch the end of the show in HD. Fortunately I had my DVR going on that channel, so I got to rewind a bit to catch up on Shran coming to the rescue.

I doubt they'll rerun it in HD Saturday, since they pass through the UPN signal on Weds. nights, but it's on tape delay Saturday, and I don't think they have the ability to do that in HD.

I guess they'll repeat it again in Sept. when Season 4 begins....

RATS! I've gotten pretty spoiled since UPN went HD with this show. Them boys at WJZY need to get 'em some HD recording equipment for just these unfortunate circumstances.

I've got a TS file of it and planned to sit down with the whole fam damily tonight to watch the season wrap-up show. This forum bailed me out; I'll tell-em what to expect. In the transport stream, there is weather radar, so I'll be able to see if there's any precip near the tower or not ;-)

I don't know if you folks have noticed, but it seems like there's always a burp or two in each airing of the show; I don't think I've ever seen a 'perfect' HD Enterprise. These are typically just a black spot (not the typical pixilization that comes with marginal signal). Call me skeptical, but I don't think this is an accident.

You're right. It seems like I get about 5 radars, but wjzy is not one of them.
