Well, my Winegard PR-8800 gives me nothing pointing at Roanoke (will try with rotor later), but my Silver Sensor gives me some signal in any direction. Nothing on my Zenith HDV420, but my Hauppauge WinTV-D was able to decode it in a sweet spot. ^^

I'll report in when I use the rotor...

I have to point my antenna directly at Charlottesville to get it, but when it's pointed there, it's got over 50% signal strength.

Much better than the analog looks!

Thanks NBC29!

I'm picking up 29.1 (WVIR-DT) so loud and clear where I am (about 10 miles west of Staunton) that the signal strength meter is at about 98.

WildWillie6, Trip in VA, Bill Johnson:

Thank you for the quick reports on reception...sounds like we have it tuned pretty well. You may be interested in the setup...we're operating a 3rd generation Thales Paragon transmitter equipped with two L3 multistage depressed collector IOT tubes running into a 2nd generation Dielectric center-fed, top-mounted pylon antenna. At the moment, this is considered a state-of-the-art transmission system.

You have confirmed what was expected...the 1,000 kW digital has greater range than the 5,000 kW analog. However, only Trip is receiving a line-of-site signal. Those of you in the Valley are probably receiving via knife-edge diffraction over the Blue Ridge Mountains. We would be interested in hearing if the signal-strength is consistent over long periods.

Quality digital transmission requires constant monitoring. If you see any unusual anomalies, please let us know.

Thanks!

My question now is this: Do you think WHTJ's digital will make it down to me here in Charlotte County? It looks like I will be getting a good deal more power from the digital than the analog.

Analog: 151 kW Directional Pattern

Digital: 340 kW Directional Pattern

Right now I can get WVIR-TV and WVIR-DT all the time with the antenna pointed at Charlottesville, but WHTJ-TV has NEVER been received, even during the strongest tropo. Right now, WCVE is brought to us by W60BM in Rustburg, but their engineer tells me that when W60BM's transmitter goes, they're just turning in the license. I want to know if I could then turn to WHTJ-DT (assuming they ever get full-power) for service. What's your opinion on this 29Guy? Others?

My giant topographical map and ruler tell me that even with the Blue Ridge I have line-of-sight to WVIR-DT's transmitter. There's a gap near Afton Mtn. with the surrounding terrain only about 1200 ft. in elevation; and that and my house's elevation of about 1800 ft. stand me in good stead. WVIR-DT is still way beyond strong today on my signal meter.

But "knife-edge diffraction" sounds intriguing and I'd never heard of this before. Perhaps that's why I can rock-solid get the DC digital stations about 125 miles away; and out of curiosity I must go back to the search engine to read more about it. I wonder how common it is and how reliable it is in not varying.

Trip, when WHTJ goes full-power (presently 8.5 kW), it appears their directional antenna will be radiating about 100 kW in your direction. I would think that would be sufficient to reach an outside antenna with line-of-site toward Charlottesville.

Bill, your height of 1800 feet is higher than the radiation-center of WVIR-DT (1767' amsl). So, I expect your height rather than knife-edge diffraction is responsible for your excellent reception. Generally, knife-edge diffraction is more reliable over hard surfaces, so the leaf-effect can knock it out in the summertime.

Thanks for the interesting information, 29. It's good to be pretty sure we aren't receiving your digital station's signal because of some quirk, especially with the Olympics in HD approaching - not to mention reception of digital signals from Fox and CBS in DC as well.

Hmmm . . . My antenna's elevation is right at 1200. I guess that means I'm getting it via knife-edge diffraction? The signal seems strong enough. With the antenna pointed right, the lowest strength I've seen on this Zenith HDV-420 set-top box is at the "r" of "Normal." (Wish they had included a numeric scale, even with the possibilities of communicating false precision.)

Also: For the record, I went back and edited the first post of the thread to reflect that WVIR-DT is full power now.

I haven't been getting anything on WHSV-DT 3-1 (49) for the past few days. Anyone know what's up with them?

As I recall from a post or talking to someone, Charlottesville will be getting an ABC and CBS affiliate this fall or in the very near futureanyone else here about this?

Now if we could just get FOX in Richmond to get up to speed I wouldn't have to spend $200 to receive the Redskin games.

This was discussed back in June on this thread and it's all at No. 3 with WW6's June 6 posting. I'm afraid they'll be operating at about a half kW and probably not digital so we in the Valley may not be affected for a while.

On another issue, WHSV-DT has had problems since it went live last year and hopefully it's just down for repairs. I haven't heard from the Chief Engineer in some time so I guess he has his hands full. Perhaps going digital is indeed rocket science.

29.1 is solid as a rock for me all the times I've checked it. Perhaps it's tmcck's setup or hardware.

Maybe I'm too close to the transmitter. I get all the Richmond stations with no problem. I about 3 miles from the tower. Right now i'm using a channel master 4228 but maybe that is too big. i'll try a small antenna.

I fixed my NBC 29 reception. I have to use a small antenna for NBC 29 and PBS only and my big Channel Master for Richmond stations. NBC 29 is now at 98% and rock solid.

You could install an $8 attenuator from RS and lower your signal strength and that should solve your problem, and you wouldn't need the additional antenna.

Would this cause my richmond signal strength to decrease?

Not a problem. It has a knob that controls the gain and it works great.

Unplug your OTA coax from your STB, and then plug that into one end of the attenuator. Then attach a coupler to the attenuators other end and screw the coupler into your STB. Done. It comes with directions and is very easy to use.

We've been told by Adelphia Cable that WVIR-DT has been added to the HDTV line-up on the digital tier in Augusta and Rockingham Counties. If anyone on this thread has an Adelphia HD box, we would appreciate comments on signal quality.

BTW, we're also told Adelphia will not be able to offer HD service east of the mountains until sometime next year due to bandwidth limitations (the Charlottesville system is only 550 mHz).

You have no choice because you are in Charlottesville, and as I said Adelphia won't be offering HDTV until next year (and 65% of the homes in the Charlottesville DMA are connected to Adelphia).

BTW, the Charlottesville analog stations will be on DISH either in August or September.

Hey, 29Guy, what do you know about Adelphia offering HDTV next year? When next year, do you know? Is that contingent on them getting bought?

Looking forward to watching the Olympics on your feed when I move back to the Hook!

Adelphia CSR told me a few minutes ago that WHSV, WUSA, SHO, HBO are on Adelphia's HD tier and that 5 more will be added on a higher tier for my zip code in Augusta Co including HDNet, HDNet movies, and ESPN-HD. She didn't mention WVIR, but of course we know CSR's are often uninformed.

The bandwidth issue is of concern. My CPU has a 500 mHz motherboard, so 550 for a cable system sounds anemic, especially when we HD fanatics are already gun shy about the lack of bandwidth and compressed HD PQ (caused by 12 or so Mb or whatever the ridiculously low quantity is). I'm also interested in anybody's experience with the Adelphia box in the Valley. I feel when it comes to HD, D* is taking me for granted after a year as a customer. But I would have to be pushed pretty hard to go back to Adelphia other than for high speed Internet (which I have & is great).

Bill, the clock speed on your computer and the frequency of the cable networks are like comparing apples and oranges. Just so you know, it doesn't mean the same thing.

____________________________

This is good to know because seeing the awfully low power that some digital stations are transmitting at can make some of us non-engineering types kind of skeptical of the whole digital world (not even to mention the terrible PQ of some supposedly HD telecasts). Don't wanna name stations -- they know who they are -- but 1.1 kW ERP for goodness sakes is not much more power than my garage door spotlight. And I don't believe this is a case of apples and oranges because a watt is a watt I have to assume.

We were told they expect to offer HD by summer 2005. I don't think that is contingent on their future ownership. While in bankruptcy they have upgraded Lake Monticello and the picture quality is outstanding!

I am also looking forward to the Olympics in HD. Crutchfield, CC, and BB will probably sell more HD sets in August than they have moved all year.
