Although the sound was bad, I double checked for surround sound and it was only 2 channel here. (Samsung 160, digital coax into Onkyo receiver.)

I had my antenna installer come to check my video drop out, and he was able to improve my 7-1 and 4-1 signal strength by changing out the 8 bay antenna, and substituting two 4 bay units pointing slightly differently; he also added a little more mast height (don't tell my wife). I am in Greenville about one mile South of I-85 and I-385 intersection (Collins Creek)
All video breakup that I saw on Sunday is gone.
Unfortunately, the audio on 7-1 was moderately garbled during the Tuesday evening prime-time broadcast period. Sure hope WSPA will do something before the S-Bowl.

Also, I noted something last night on4-1. My Sony menu showed a 720P signal. I thought NBC was 1080I. I'm pretty sure I've seen 1080I there before. The picture was still 4:3 as usual. SZ

You stated the signal was 720p on NBC last night and the picture was only 4 X 3. Everything I watched on NBC last night (including the State of the Union address) was 16 X 9 HD. I think ABC had the pool feed for the SOU address and they do 720p, so maybe that has something to do with you seeing 720p indicated by your receiver.

Also, what model antenna do you have? Anytime I have tried to combine it antennas it created more problems than it solved.

Re: WSPA-DT audio, I will ask for a report on progress solving their continuing audio problem. I had to switch last night from WSPA's SOU to NBC because of the audio, and was surprised and pleased the coverage was wide-sceen HD.

Jerry- The State of the Union started out in HD on WSPA-DT. The sound was even worse than normal. I guess that is why they switched to the SD feed.

Stacking like antennas, especially pointed the same direction, is relatively simple using coax combiners/splitters with equal length cable between antennas and combiner. However, aiming in different direction can become more of a problem with phase cancellation from side reception of the same signal. This can be partially corrected by careful turning of the antennas while observing the signal. Too bad an inexpensive spectrum analyzer is not available...or that one of the stations doesn't make one available for loan to those of us pioneering the reception end of DT.

Multi-casting seems headed for debate in Washington. Read an interesting article in: www.skyreport.com
This is another aspect of "HDTV" that is sure to create delays.

"Stacking like antennas, especially pointed the same direction, is relatively simple using coax combiners/splitters with equal length cable between antennas and combiner." When I tried this it just seemed to make my multi-path problems worse.

"We are in the process of upgrading our network receiver as well as the Dolby 5.1 surround sound. This is actually taking place today 1/22/04 and should be online very soon. "

Young and the Restless is showing up as 5.1 on my receiver. I believe this is only DD2.0.

What antennas were you stacking? One crude way to check is to look at an analog from the same antenna, close in frequency to your primary DT objective, if one is available. You can see ghosting (multipath) and make adjustments for phase cancellation. Side lobe signals would be increased but only in relation to the original signals and you should have greater gain on the primary lobe. Were you using an amplifier--which could really complate the problems?
post #132 of 10303
Jerry: I stacked cm4221's with a cm7777 pre-amp. I also tried with cm4228's. I tried with and without the pre-amp. It was over a year ago that I tried this. I did alot of experimenting and the best results came with the 4221 with the 7777 pre-amp.
post #133 of 10303
Also: I lost a little range (WBTV-DT) with the 4221 vs the 4228 but found I didn't have to use the rotor nearly as much with the 4221 so I stuck with that.

If you have not seen these websites which have the patterns for your two CM antennas, you may find them interesting and potentially good info for your particular experiences. With the CM777 and your close proximity to the WC transmitters, I have very surprised you do not experience a severe front end overload. The CM777's very high gain with the extreme gain of the antennas would blow my equipment out of the box! The side-lobes can result in really interesting results.

Otherwise, I certainly agree with your approach in trying various equipment for best results. As I have said before, I have one small place at the corner of a rear (south) deck that I can get all stations from one position with a CM 4-bay and no amp...any movement up, down, side to side, or amp will upset my setup and I will lose a station or stations.

I've got a question about WSPA TV. Since I started using my HDTV receiver I've had trouble getting WSPA using my roof mounted antenna with a booster, which pulls in most of the other area stations fine.

The signal here should be very good for this channel so I basically narrowed the problem down to multipath and decided to try an indoor antenna for it. I picked up a Silver Sensor and it has improved the picture quality overall but i'm still getting pixellation in certain places.

While watching their news or a TV show the picture is fine when the newscast or program is playing, but when they go to a commercial at least part of the screen turns into pixels when they make the switch from the feed to the commercials, and this also occurs during the commercials themselves. When the program returns it does it as it comes back on but then it clears up again right after that.

Anybody have any suggestions? With March Madness coming up I really need to be able to pick up CBS, that frankly is the whole reason I invested in HDTV hardware in the first place. It obviously can't be a weak signal or I wouldn't be able to pick it up with the indoor antenna, and the outdoor one would be clearer.

Since WSPA-DT increased it antenna height and went full power early last year I have found their signal very stable with no pixelization. (My only problem now is the audio, which they are working on). Perhaps we can get a WSPA engineer to take a look at your comments and offer suggestions. I will send a note to the CE asking for help...because several people have similar problems.
BUT, I must add...I am very cautious about boosters, especially with high gain antennas.
post #137 of 10303
Jerry I agree with your booster analysis, the signal looks HORRIBLE with the boosted antenna. It comes in clear however with the indoor antenna (which TitanTV and the old Antenna web noted would be sufficient), it just breaks up at those "spots" I mentioned in programs. The remainder of the program plays fine.

It's almost like an encoding problem but since others haven't mentioned the same problem I don't think that's it.

It's almost like the signal is too strong with the boosted antenna (or is suffering from multipath issues, OR Both) but with the Silver Sensor there are still tiny patches of video breakup. The audio remains consistent however.

I wonder if I should try a multi-directional indoor antenna and see how that works?

fishman and all

I'm going to take back what I said in an earlier post about my LG3200A not being as sensitive as the old DTC-100. It was "pilot error". In my haste during initial setup, I was a little careless on my zip codes for the local channel program guides. Last night I noticed that several channels in the guide were inconsistent with the actual programming (e.g. WSOC out of Charlotte was actually coming in but on the guide it was listed as 35-1 PAX instead of 34-1 ABC) . After fine tuning those set-up zip codes things are where they should be and I am (at least this am) getting a usuable signal from ABC Charlotte on 9-1.

WSPA-DT's audio sounded very good last night.
post #140 of 10303
I thought so too. Did your receiver indicate 5.1 even though it is actually only 2.0?
post #141 of 10303
I thought it sounded better, but I had lip synch issues. Did you guys not have that?

Mike
post #142 of 10303
No lip sync issues for me. I get this on my E86 occsionally and I just cut the box off and then on again and that put the lips back in sync for my unit.
post #143 of 10303
Apps1 thank you, that seams to have solved the problem for me.

I just caught a promo for HDTV on WSPA. The jist of it was they were the only source to get the Super Bowl in HD and Surround Sound. They mentioned at the end to contact your cable company about carrying WSPA-DT. Maybe this will motivate Charter, WLOS, and WHNS to get their butts in gear.

Just asking here now, but why should it? They do not have a marque event to push like the Super Bowl.

"Just asking here now, but why should it? They do not have a marque event to push like the Super Bowl."

I dont see this as really being about 1 Football game. Hopefully it will increase awareness of HD in the area, and lead to more people asking their cable companies and local affiliates to pass along the HD feeds. I would think the more people asking to receive the HD feeds only helps to get these companies at least thinking about the prospect of providing what customers want.

But FOX does have NASCAR in widescreen and maybe it will help get WHNS off their cheapskate rears and put it on in widescreen.

All: RE: WSPA-DT
My audio was a few frames out of sync duirng the Super Bowl coverage last night. Anyone else notice the problem?
post #149 of 10303
The only thing that was out of sync on my end was the Half-Time show. What were they thinking? I had no audio problems.

Re Super Bowl/Audio sync
My Samsung TS 160 in itself does not seem to cause sync problems. So far, when this has been a problem the stations have confirmed the problem is on their end. WSPA has had continuing problems with its audio...both drop outs and out of sync. Their recent installation of new equipment was to have solved that, and it did seem to do so during my too limited monitoring for the past 10 days. I did not notify WSPA's Ron Peeler of my observations during the Super Bowl, and would like to have a few other comments prior to sending him a note. I will include your comment when, and if, I communicate with Peeler.

PS: We have far too few participating in our forum! Lets try to build awareness.
