are all the digital stations reported by antennaweb in norfolk really broadcasting? i am using a cm4228, about 40 feet up on a tower. i am in williamsburg about 33-35 miles from driver. i get the following stations:

3 wtkr
10 wavy
15 whro
13 wvec
43 wvbt
49 wpxv

i seem to be getting all the sub-channels. signal strength is anywhere from almost "strong" to almost non-existant. but the pq is perfect. some dropouts on occasion, but not many. and then its only on one channel. i even got a richmond station the other morning (fox, i think).

i guess my basic question is: whats up with 27 (upn) and 33 (wb)? are they out there? low power?

sm.

All of the stations are up and on-air. I'm in Mathews County (47) miles from towers and I can pick them all up with a CM-4228 with a rotor and CM-7777 preamp. I switched out a RS amp but see no difference in performance. If you go the RS way get the more expensive one with adjustabe attuenator.

Unlike WAVY-DT, WVBT-DT has a directional antenna with a cardioid pattern. We were not able to maximize to 5,000kW with an omnidirectional pattern without causing predicted interference to NTSC Ch.29 (WVIR-TV) in Charlottesville. The upside is that this stretches the coverage to the Northeast and Southeast just a bit above where it would have been for an omnidirectional antenna at that power and elevation.

I have no idea if it's the case, but there's always the possibility that the reception of WVBT-DT is being affected by the distant Ch.29 NTSC signal.

Les, any reason the Vikes vs Packs game isn't in HD right now?

Les,

Thanks for the FCC maps of your stations. The FCC Website has always been a mystery to me. I tried several times, starting at www.fcc.gov, and even working backward from the links you gave, and can't find such links to your or other local stations. I even tried a search for WAVY-DT and got only text based triva. Could you please give the magic links (or starting URL) you used to get your maps? Hopefully I can use it to find similar information for all the local stations. I found WHRO's once, in text form, but had to plot it myself.

I doubt the problems with WVBT are due to distant co-channel interference signals. The atmosphere has been rather "quiet" lately. I suspect ghosting and intermodulation in overloaded amplifiers -- driven by poorly designed/oriented antennas.

I have had my own problems this week (and last week) in Hampton with some annoying short dropouts from WAVY-DT and WHRO-DT. These appeared without me changing my antenna. Since everyone else on this thread was complaining about dropouts from WVEC-DT last week, I decided my problems must be of local origin. Sure enough, I looked South from my 3rd floor apartment balcony (where my Voom/OTA antenna is located) and noticed the new 3-story steel building (National Institute of Aerospace) going up about a city block away -- right in my path to Driver. The steel has been up several weeks, without any reception problems. However, I noticed this week that they have started to put up the skin on the building, but they have erected massive steel scaffolding all around the building.

I adjusted my antenna and got rid of the problems. In fact, the best results for local OTA, now, is with the main lobe pointing toward WUND (ch 2 and 20) at 188 degrees, instead of toward Driver (201-209 degrees)! So be it (at least until they remove the scaffolding).

From www.fcc.gov click on Search and then TV Station Query.

On the TV Station Query form simply put in the 4-letter call sign of the station in the Call Sign field. No need to enter any other information. Click on the button to submit the data.

The search results will probably return both the NTSC and DTV stations for those call letters, with both being identified with the same Facility ID. Click on one of the Facility ID's to bring up more detailed information.

At the bottom of that info for the DTV station click on Area: Service Contour Map (41 dBu) to get the map.

The FCC just recently added these maps to its website. They also have most maps of FMs...

And Les, WVBT-DTs oval-like coverage pattern does stretch north and south, interesting...

Les thanks for the links. I checked WWBT-DT in Richmond map against WAVY-DT. Interesting.

WWBT-DT Richmond

WAVY-DT

There is quite an overlap between Richmond and Hampton Roads.

As noted in one of my recent posts, I had an HR10-250 failure which D* quickly replaced at no charge to me. For those of you having problems with your new machines, I recommend going to the AVS Forum "HDTV TIVO POWERED PVR's" and read what others are saying. Both my "freeze-up" problem and another member's "HDMI problem" (and others) are mentioned along with cures. This new product is great, but it does have its growing pains. Luckily, D* is a great company standing behind its product.

Ok, after going through all this work to get the antenna up, get signals on all the channels and grounding. Someone please tell me the locals here are not going to be offered on D* soon and all that work was for not. I guess I have a backup antenna for the locals now?

Just a thought. Antenna web says you need a directional antenna. Maybe stop screwing around with the bi or multi directional antennas. Im only 20 miles from all the towers and was unable to get one of those multi or bi directional things to pick up everything.

Yeah I bought a 4228. D* bought the POS bi-directional Winegard and threw it up on my roof, not my choice.

Dale
post #942 of 7950
Where did you buy the 4228?

I am still looking for a good cabler, installer to install an atticd antenna and do some addtional wiring that I will need for my new TV. Any suggestions for someone reasonable in the Virginia Beach area.

The locals are offered by D* now and have been for some time but not the HD feed. Reception of local HD requires either an OTA antenna or Cox Cable and Cox does not carry all local HD content.

hi again dale

D* has stated they PLAN on offering HD locals in the top 30 markets when the 1st of 2 new sats are up--DUE to be launched in 3/05, 2nd sat. in '07. im GUESSING best case for Hampton Roads(DMA#41-i think) might be Dec '05 but will probably be longer. so your time & effort has brought you 13-18 mos.(or more) of HD programming you'dve missed!! ENJOY!

I bought it online at solid signal. www.solidsignal.com I think. I think an attic installation might be easier then you think. You might want to attempt it yourself. I would just take a small tv upstairs in the attic to aim the antenna. Once that is done, run the coax down to your tv.

A decent compass would work too. The HR locals, for me, are just two degrees apart. No need to haul a TV into the attic...

WUND-DT/20 (2-1) is coming in very strong tonight here in Virginia Beach... high 80s on "the meter." How far north is their signal receivable???

Yeh, I was watching TAR6 too but thankfully was only a few seconds behind at the time and switched to DirecTV for the signal. BTW, the sound was out earlier today on the DirecTV feed for channel 3...

Its been several days since Les Garrenton gave us the magic link to all the FCC information on local TV at http://www.fcc.gov/mb/audio/tvq.html -- so I just wanted to thank him.

I have spent literally days looking at the super trivia, like antenna patterns, tower owners and locations, and applications for of all the local stations (I know, get a life!). But, to an old engineer, its been heaven. So, I have a few questions that I hope Les (or any other engineers or TV execs) can answer:

1. What will happen to all the many local "low power" and "class A" stations when the FCC pulls the plug on analog TV? [Note: you find these by searching the website by each local city name: Norfork, Chesapeake, Hampton, Virginia Beach, Suffolk, etc.]

2. I can understand that there may be a small audience for "narrow casting" for low power stations with "religous" or "shopping" content. But, what is the purpose of the many WAVY-TV channels (replicating its Ch 10 programming verbatim) all over the dial -- particularly in a world where everyone gets their analog TV by cable, and not by antenna?

3. What is the status of the many construction permits for a Channel 21
(analog) in Virginia Beach? Although most were filed in 1996 and one in 2002, they mostly seem unresolved (neither granted or denied). Is the FCC that inefficient -- or did I not find all the information?

Next, I will check out the links to all the local FM (http://www.fcc.gov/mb/audio/fmq.html) and (http://www.fcc.gov/mb/audio/amq.html) AM radio stations. I'm sorry if this is a bit off-subject (HDTV) but there have been no posts for days on this thread...

hi dale(dkyork)

if remember correctly you mentioned you had a new JVC D-ILA display. if the install is over & all is running well can you give us a real world review of the PQ? if you saw the CEDIA 2004 show on HDnet you'll know these displays were given a detailed presentation. so in short-how's it lookin' for ya? inquiring(geeky) minds want to know! LOL!!! Enjoy the HD!

jim

PS are you getting all your locals OTA now?

This is a nice set! I was never looking at the JVC. My wife liked the look of them. Started my research and we end up getting it over the DLP and LCD displays...

No JVC here. Have a 5063 that I'm returning as soon as my 5674 comes in. Dont' have all the HD channels quite yet. Tbyron is comign over today to help me align the antenna and think of other alternatives. Hopefully we can get this thing working.

Thanks Var, but Byron came over and we get all of them working. He fell through my attic floor though, thank GOD he was safe!!!! Got a drywall guy?? lol j/k, I'm gonng repair it myself. We ended putting a 4228 in the attic and have 80-90% signal on all channels now! 33 was a little tough getting in without losing 13, but I tilted the antenna up about 15 degrees and got em both.

Dale, no drywall guy . Good to hear you're up and running. From your location, can you receive any of the Richmond DTVs?

6-1, 8-1, 12-1, 35-1???

That's a good question. I haven't done a new scan since the new antenna was put in. I'll do it tonight and let you know what I get. Byron noticed during an analog test, with his little tv, that I was getting one Richmond station barely.

6, 8, and 12 came in on analog with very poor reception. Didn't get the digitals though. Oh well, I'm happy with all the local ones. Good solid signal makes for one happy HD fanatic.
