W30DT-D is on the air from Massanutten Peak in Rockingham County. For the next couple of days it will run at about 900 watts. We will crank it up to full power by the end of the week.

The transmitter is licensed to identify as channels 30.1, 30.2, and 30.3. However, due to a defective mini-mux, for the next several days it will identify as 29.1, 29.2, and 29.3.

Reception reports would be appreciated.

Yesterday evening around 7, the reception just north of Crimora was excellent. I was able to disconnect the antenna and literally use a straightened out paper clip in the back of a converter box to grab the signal! The specific turner that I have in the bedroom does not show percentages or dbm but would estimate 85% signal on the paperclip.

One other report from New Hope was marginal; they received the analog 28 feed "good enough" to great in the past. I let them know that you were operating at a reduced output and to check it each day this week for changes.

Once you go full output on this feed I would appreciate a heads up, and I will try to collect some more reception data.

Thanks,

Jeremy

PS: I see your construction permit licenses is listed as 15kw, will this be the expected output when this station moves to final licensed state.

Thanks for the excellent report. We expect to be at full-power sometime this evening...I will let you know. Also, I may have mis-lead you somewhat when I said we are running at 900 watts. In the transmitter business we think in terms of the power we can control, not the effective radiated power from the antenna which is fixed. When we increase the transmitter power to 1,300 watts then W30CT-D will be radiating 15 kW.

Significant issues tonight. Each TV is handling it different but the over all problem is video "stuttering"/choppy.

Also one TV is not picking up the audio feed, while another will not pickup WP or CW.

Transmitter now at full-power with new mini-mux installed to identify channels as 30.1, 30.2, adn 30.3.

We see the same problems you have observed and are continuing to make adjustments.

We believe the problems were corrected this morning. The mini-mux was not set to sufficient bandwidth.

So, W30CT-D is officially on the air identifying itself as channels 30.1, NBC29, 30.2, Wx+, and 30.3, CW29. The transmitter is running an ERP of 15kW and should reach most of Rockingham County, plus the northern half of Augusta County, from its location on Massanutten Peake.

Hey, folks:

I've got another antenna story, but this one's pretty much concluded. More of a documentation than anything else.

My friend lives in Staunton and on the way back from a trip to Virginia Tech a few weeks ago, I stopped in at his house. Turned out he had a great view of the mountains and I pulled out my spectrum analyzer and saw that he had lots of signal on Richmond and other things. With this encouragement, he decided to pull out the old TV antenna again, put it up on a pole tied to his fence, and gave it a shot.

The results were disappointing. The only reliable signals were 29-1 (WVIR-32), 41-1 (WHTJ-46), and 65-1 (WUPV-47). He'd see 6, 8, 12, and 35 from Richmond in the mornings but they'd disappear any other time. He could also see 3-1 WHSV if he aimed right at it, but since he has that on cable, it's not as much of a concern.

He was using what looked to be an old Radio Shack roof antenna of some kind, looks to be about medium range rather than deep fringe, fed through RG-6 to RG-59 to a Radio Shack powered splitter which then went to his two TVs (Sony and LG). I loaned him my Zenith CECB and it outperformed the TVs in a huge way, but since it wasn't HD, he couldn't use it for viewing.

Yesterday, I went up there and we tried lots of different configurations. We settled on his same Radio Shack-looking antenna elevated MUCH higher, from a different fencepost such that the RG-59 could be removed. When I left, through the amp and everything, he was receiving:

6-1
8-1
12-1
16-1
19-1 (Marginal)
23-1
29-1
35-1
57-1 (Only with my KT-200, not present with the Sony amplified splitter)
65-1

You may note the oddly missing station, WHTJ-46 (41-1). Looking at my analyzer, it was definitely present but with a very deep gouge at the lower end of the channel. I suspect the Zenith would have handled it fine, but the TVs were seriously unhappy. Since he gets 23-1 now, however, I told him that he didn't need to worry about WHTJ, so as long as it remains reliable, all should be good.

The real oddity was the absence of the Staunton stations (WVPT-11, W41DT-41, WHSV-51). WVPT-11 had more signal than WWBT-12 the entire time I was there playing with it, but it never once decoded. He does have a hill behind him blocking those signals, but as much as the analyzer was showing signal, one would have expected a decode out of it. Even when we turned the antenna that way, no luck. But, again, since he gets WVPT and WHSV on cable, and W41DT repeats WVIR which is reliable, he wasn't interested in fighting with those signals.

We tried to get Roanoke since it's there on the analyzer (17, 18, 36), but the surrounding buildings and terrain chopped the signal to pieces, so we gave up on that pretty quickly. If he was higher on the hill, Roanoke would probably be feasible for him. At various times, I also saw signals present on 7, 9, 31, 33, and 34. I'm assuming all of those were DC (7, 9, 34) and/or Norfolk (7, 9, 31, 33). These were well below decoding and I suspect a result of atmospheric conditions.

Here's a report on the RabbitEars DX Tool for his location. Bear in mind that WHSV-49 only works when it's aimed in that direction, so his permanent aim does not allow for 3-1.

Oh, and I spotted an analog on 39. Could W39AK be back on the air, or was it a Richmond analog?

I'm getting good reception in Bridgewater, Va., with a ChannelMaster 4248 and 7777 preamp, antenna about 25 feet above ground level. All three subchannels are good. The antenna is pointed about 45 degrees away from W30DT to get Richmond stations, but signals are solid.

Signal strength is a steady 66/100 on a DTVPal DVR -- yes, I know it's not a very good indication of signal strength -- but native NBC 29 is highly variable this time of year, from upper 50s (breakup) to low 70s. And, as we all know, a low indicated mean signal strength can still be solid if the variance is low -- which it is for W30DT.

Bottom line: I can see W30DT reliably now, while NBC29's native signal is iffy as long as the leaves are on the trees.

Thanks, NBC29 and 29Guy!

A few months ago, I accidentally cut my 150' run of rg11 from antenna to house. I hastily and sloppily sliced it back together and everything seemed fine. Then last month I started losing reception. I figured water had gotten into the splice or the coax (it is burried in the ground), so I replaced the whole run of coax, but reception was the same. I then bypassed my CM 7777, and reception was much better (though not as good as before).

Is it possible that water in the splice or coax could have shorted out my preamp? I'm not much on electronics, but is there is any way to test the preamp?

Thanks.

Sounds like it might have shorted it out! I do not know of a way you could test it.

They seem to be having OTA problems, they were off the air at 6 this morning also.

Monday morning and Monday night the station was off the air in Culpeper. This morning (Tuesday) it is so weak and fading in and out. It would be nice if NBC 29 would put something on their website for those of us 40 miles away with a weak or no signal know what the problem may be and when it is loikeloy to get fixed. Fox 27 disappeared as well, but ABC16, usually weak and the much stronger CBS19 were putting out a nice strong signal in CUlpeper Monday night. Maybe 29Guy will let us know something.

I was able to get WITN from Greenville, NC last night since they share RF 32 with WVIR.

NBC29 experienced more than the usual backyard or professional fireworks over the 4th of July weekend. We had fireworks of the supernatural variety. Sunday Night we took a direct hit which knocked out the primary exciter in our main transmitter, then Monday Night another hit took out the secondary exciter and transmitter control panel. Currently, we are operating on our 1000 watt emergency backup, so, reception beyond about 25 miles will be hit or miss. All Shenandoah Valley translators are operating normally.

We expect the main transmitter to return to service by the end of the week.

29Guy thanks so much. I look forward to NBC29's return to the airway here in Culpeper. Who said lighting doesn't strike twice in the same place?

Ditto--thanks 29guy, am getting tired of going outside and turning the antenna toward 29 to see if it's back yet! Am sometimes able to pick up NBC on channel 12 Richmond, but for the past week without 29 I rely on 4 stations on channel 3, I think whsv, that I pick up with antenna pointing due west from Sperryville.

Local radio is reporting that W18AA, a low-power license formerly serving as a translator of WUSA-9, is up for reallocation. As I understand it, the current licensee Rockingham County will look for proposals, and pick one to jointly present to the FCC. Both a low-power TV station and a translator are said to be possibilities. This is a nice piece of spectrum with good central Valley coverage. Most of the covered area has little interference from WDBJ on 18 (as Roanoke is a two-edge, 90+mile proposition for viewers).

NBC29 main transmitter is back on the air at about 50% power which should be enough to serve most viewers. Will return to full-power when protective circuits are repaired, probably Monday. Can't afford to blow $38K tubes.

First, there's a good discussion ongoing on the Greenville SC board - if anyone would like to join us. It's "all things" DMA, such as why boundaries are the way they are and how a county can "move" from one DMA to another. My question HERE is - why are Harrisonburg and Charlottesville separate DMAs? I don't live in the area, but have traveled the area enough to know there is that big Shenandoah barrier. Is this the sole reason for two separate markets? If so, there are other geographically-challenged markets like Greenville-Spartanburg-Asheville. So far as OTA signals for those living in those nooks and crannies of the NC mountains north and west of Asheville, many are unable to get the signals from the SC side of the market - or maybe vice versa. I believe the same could be said for WSET getting a signal to the areas north and west of Roanoke. So, again, I just have a curiosity question about why Charlottesville and Harrisonburg are separate? And maybe it's solely "the mountain." Thanks!

I always thought Culpeper was part of the DC market. Are the DC stations not receivable OTA? I thought they were back in analog days. Are they carried on cable/sat?

Although Harrisonburg may be a separate market, the DC stations have always been carried on cable/sat there, and the DC channels in the past had translators to serve the Shenandoah Valley.

NBC29 has returned to full-power. If you are still having difficulty with reception, please re-scan your receiver.

We apologize for taking so long to return to full-power. The lightning damage was greater than at first thought.

A Nielsen DMA (Designated Market Area) is formed when a station or stations generate more combined audience in their home county than any group of stations from an outside DMA. Counties move from one DMA to another based on the same principle.

The Harrisonburg DMA was formed in the 1950s, and the Charlottesville DMA in 1990. For Charlottesville and Harrisonburg to form a hyphenated market there would need to be some signal or economic overlap, and all the stations in both markets would need to agree. With the exception of NBC29, there is little signal overlap, and none of the stations have shown any interest in combining markets.

You are right, Culpeper is in the DC DMA and yes, I receive DC stations on satellite. However, I am 42 miles from Charlottesville and more than 60 miles from DC. I would rather watch Charlottesville news and weather (only available OTA) as it is more relevent than watching DC stations talk about DC politics and traffic jams. Hagerstown Md is also in the DC DMA, yet it is farther away than I am. I have no clue how these DMAs are set up. Orange County which is within spitting distance of Charlottesville is in the Richmond DMA. And on it goes. What is really odd in Culpeper is Comcast cable has NBC29 in Charlottesville on its Culpeper system along with CBS from Richmond and CBS and NBC from DC. That is really mixing and matching DMAs. God figure. Thank goodness I have an outside antenna so I can receive Charlottesville TV..
post #3570 of 3703
I have "no signal" on all of the channels I normally get in Charlottesville, including NBC29. This is since yesterday (Friday). How do I know if this is some broadcast problem or if it is my converter box?
