Digital Transition Answers

Digital Switchover Will Be Here Before We Know It

November 24, 2008 11:54 AM

Well, we have less than 3 months left before the end of full power analog television transmission. The switch to digital is approaching rapidly. Where do you stand? Are you prepared? I hope so, because it will be here before we know it.

I am going to touch on some odds and ends this morning. More or less an update as to what has been happening around here as far as the transition to digital is concerned.

I finally got around to cutting the antenna that was felled by Hurricane Ike off of my roof last weekend. I was able to salvage most of the telescoping antenna mast, mainly because I did not have it extended all the way up. I was able to piece enough together to allow me to erect another antenna to within about 3 feet as high as my old one. That is OK for now—it will save me the cost of buying another mast or imposing on my friend for some pipe. It will be adequate for the time being.

I am going to replace my Radio Shack VU-190 XL antenna with a Channel Master 3671 deepest fringe antenna. I already have purchased a CM 7777 signal booster. I just need to find the time to get it all put up. I will be out of town most of the Thanksgiving weekend, but I will find the time soon, I am sure.

There are a couple of things happening here on the home front concerning the transition to digital. I am going to give a run down of where we stand here in the Beaumont/Port Arthur, Texas market.

The biggest story to hit the news here in the last couple of weeks was surely a surprise. Our local full power NBC station, KBTV channel 4 (digital channel 40) unexpectedly announced at the end of October that they were ending their 51 year relationship with NBC and were to become a FOX network affiliate on Jan. 1, 2009. This leaves us for the time being without an NBC station.

At this time, KBTV transmits a micro power signal of 1.28 KW (1,280 watts) from their 1,227 feet above ground (AG) analog transmitting tower in Vidor, Texas. This tower has been deemed "structurally unsound" to support the weight of the full power digital antenna. This tower already supports the KBTV analog antenna, temporary digital antenna, and the antenna for the 100,000 watt FM radio station KIOC. KBTV claims that they are going to increase their low power digital signal enough to cover 85% of the KBTV analog viewing area.

KBTV attempted to negotiate a contract with KVHP channel 29 (digital channel 30), the FOX station out of Lake Charles, Louisiana, but was unable to come to terms on an agreement. KBTV has opted to begin construction of a new tower immediately adjacent to the existing tower, and claim that the tower will be finished by Feb. 1, 2009. KBTV has been granted a construction permit extension until Feb. 17. 2009. KBTV states that the transmitter and antenna have been ordered, and that it fully expects to be up and operational at the end of the transition period. KBTV is transmitting a 480 standard definition signal at this time. There has been no word as to what future HD standard they will adopt.

I am not surprised that a contract could not be negotiated with KVHP. That would have put two full power FOX television stations on the same tower, Duh.

KFDM channel 6 (digital channel 21), a CBS affiliate, has constructed their final DTV facilities, but they are awaiting action from the FCC on a maximization application to increase the effective radiated power (ERP) from 50KW (50,000 watts) to 280 KW (280,000 watts). KFDM transmits from a tower that is almost 886 feet high above ground (AG). and they transmit a 1080 HD signal on the main channel and a 480 SD signal on the sub-channel 6.2 that carries the CW network.

KPLC channel 7, an NBC station, which is available to some of the viewers in our area, is broadcasting a digital signal on channel 8 at this time, but will revert to channel 7 after the transition. KPLC has constructed the full power final DTV facility and will commence digital broadcasting on channel 7 on Feb. 18, 2009 at an ERP of 31 KW from an antenna that sits on a tower that is 1,480 feet AG. KPLC carries a 720 HD signal on the main channel, and 24/7 news and weather in SD on the 7.2 sub-channel. They also carry a notice that The Tube, a music video network is no longer available due to circumstances beyond their control on sub-channel 7.3.

KBMT channel 12, an ABC station, is broadcasting a digital signal on channel 50 at this time and had been granted a Special Temporary Authority to continue to broadcast on channel 50 until Aug. 8, 2009. The new digital transmitter is expected to be delivered in late January or early February. At the end of analog broadcasting, the analog channel 12 antenna will be removed, and the new digital channel 12 antenna will be mounted on the 980 feet AG tower. The analog channel 12 transmitter will be removed from the cabinet, and the new channel 12 digital transmitter will be installed. The conversion to digital channel 12 is expected to take about 30 to 45 days from the end of analog broadcasts, and KBMT should be transmitting the authorized full power maximization power of 160 KW well before the Aug. 18 deadline. At the time that the channel 12 digital transmitter is operational, the channel 50 transmitter will be shut down and the digital channel 50 antenna removed from the tower. KBMT is transmitting a 720 HD signal on one main channel. There has been no word as to what programming, if any, KBMT will employ on any future sub-channels.

KLTL channel 18 (digital channel 20), a Louisiana Public Broadcasting (LPB and PBS) affiliate is available to the eastern 1/3 of our viewing area, and is broadcasting a digital signal from a tower that has an ERP of 55 KW from a tower that is 977 feet AG. KLTL is awaiting action from the FCC on an application to move to the KPLC tower and transmit 75.6 KW from a height of 1,400 feet. KLTL transmits the LPB and PBS on the 18.5 sub-channel and LPB and PBS in SD on the main channel of 18.1. Alternate programming is carried in SD on the 18.3 sub-channel.

KVHP channel 29 (digital channel 30), a FOX affiliate, is broadcasting a mini-micro signal of .2 KW (200 watts) from the studio to transmitter link (STL) tower at the studios on I-210 in Lake Charles, Louisiana. KVHP states in filings with the FCC that there is no room in the transmitter building to house both the analog transmitter and the digital transmitter. The new digital transmitter has been ordered, and was scheduled to be received back on Oct. 31. The antenna is scheduled to arrive in early December. KVHP states that at that time, installation of the transmitter and antenna will commence, which may cause an early termination of analog broadcasting, although, in the DTV update filed with the FCC, they claim that analog broadcasts will continue through Feb. 17, 2009. So we will have to wait and see how this all plays out. KVHP has a granted construction permit to transmit a 1,000 KW ERP signal from the tower east-northeast of Lake Charles, and west-northwest of the Beaumont/Port Arthur area. The antenna will be mounted 1,038 feet high on a tower that is 1,289 feet AG. KVHP transmits FOX in 720 HD on the main channel and FOX in SD on the 29.2 sub-channel.

KITU channel 34 (digital channel 33), Trinity network affiliate (TBN), has constructed the final DTV facility broadcasting 500 KW from a tower 1,026 feet AG. KITU does hold a granted construction permit that will not expire until Aug. 7, 2011 to maximize the ERP to 1,000 KW. KITU transmits 5 SD channels of programming.

KUIL channel 64, a low-power station which uses a digital transmitter (K36ID) on a tower 20.53 miles away from the analog transmitter, has been carrying the FOX network, but will lose that affiliation after FOX moves to KBTV on Jan. 1, 2009. There have been reports that KUIL is actively pursuing an affiliation with the NBC network, but there has also been speculation that NBC will end up on a KBMT sub-channel. Official word from KUIL has been silent for a couple of weeks now, so there is a lot of uncertainty in the area. The owners of KUIL were the successful bidders in an auction conducted by the FCC which started on Nov. 5, 2009. They won the right to apply for a construction permit to build a digital transmitter on channel 43 at the same site as the analog transmitter for channel 64. This should help their case for getting a NBC contract. This will give them two low power digital transmitters 20 or so miles apart. This will greatly improve their coverage of our area.

The channel 36 digital transmitter has an ERP of 15 KW broadcasting from an antenna that is 525 feet AG. And the new application on digital channel 43 calls for a and ERP of 15 KW from an antenna 361 feet AG. At this time, K36ID transmits FOX in 720 HD on the main channel and FOX in SD on the sub-channel 64.1.

I have talked to the owner of low power KUMY channel 22, a My Network TV affiliate who holds a granted construction permit to move to a different tower nearer the center of our viewing area. He has stated to me that at that time, he will convert the station over to digital, although there is no application showing on the FCC Web site to have been submitted to do that at this time. The minor change to an existing station, which authorizes the station to move to the more centrally located tower, construction permit expires on May 3, 2009.

So, there you have it. That is what is happening here on the home front down here in my neck of the woods So keep your antennas reaching for the sky and as they say, stay tuned.

The Beaumont Enterprise and the Port Arthur News both had aritcles today that stated that KBMT channel 12 (digital channel 50 for now) announced that they would be the new NBC affiliate for our area, ending several weeks of speculation as to where, if at all, NBC would land. ABC will be carried on the main channel, 12.1 and NBC will be carried on the sub channel 12.2, both in 720 HD.
There has been no word from KUIL-LP, channel 64 (K36ID-LD) as to what their future plans will be as to prgramming.

mary... the cat lady:

I got an e-mail from KUIL-LP channel 64 this afternoon stating that they would soon be announcing a re-branding as an independant station. The e also stated that other than the loss of FOX network programming, the content of the station would remain the same.
This now gives our area all 4 of the major television networks, as well as the CW and MyTV networks and now an independant station.
To be fair, I must mention that we do supposedly have an America One network translator, KPPY-channel 53, in Beaumont, however I would imagine that there are only a handful of veiwers that are able to recieve the station. I have a friend that lives less than a mile from the transmitter, and we have never been able to get it at her house.

I'd like to submit my website to http://www.tvweek.com/blogs/digital-transition-answers/ to be added to the blogroll. We are a dedicated forum with 800 members strong and growing everyday. In exchange, we would add a blogroll section (or Partner Links) to our forum on the right side just below our advertisements.

Please contact me as soon as convenient. I stumbled across this page after searching for converter box reviews and hel. Great resource, and if we agreed to exchange links, you would be the first link added to our site.




Since the switch is already here..

such as WBGU-27 1 through 4, on 12/15/08... Then Hawaii 10 days away from now, any thoughts or predictions????

The rest of the country is next.

Any known advancements to DTV signals or technology that you care to share?

Hi EmmGee=Ohio,
I kinda feel like we have jumped out of an airplane and are free falling toward the ground. I am not so sure that everyone's parachute is going to open in time.
I am pretty confident about myself, but I worry about everyone else.
I had to replace my outdoor antenna because of Hurricane Ike. I went with the CM 3671 "deepest fringe" antenna and a CM 7777 pre-amp. I am extremely pleased with both. I found that I had moisture corrosion at my terminals on my old set up, so I countered that this time with not only a liberal amount of di-electric grease at each terminal (such as where the coax connected to the transformer at the antenna, but also at the connections on the pre-amp and the downlead into the house), but also I silicone sealed all of the rubber boots around those connections too. Anything to help keep the rain and moisture out of the connections.
Whereas I could only get KPLC-DT on occasion before, I have gotten it every time that I have tried it with the new set up. KPLC is over 60 miles away, and is listed as a second tier on the tvfool.com web site for me, and my new set up is about 3 feet lower than my old one due to having to salvage what I could of the old telescoping mast that had bent over onto the roof. I am very pleased.
It wasn't cheap, but it was worth it. I highly recommend the CM 7777 anywhere that a pre-amp may be needed.It is not by any means new technology, but it works.
I am just waiting for the fallout of the final shut off of the analog stations... I am sure we will hear all about it.


You are right, The CM 7777 does work. Its been a while since I had seen mine, but if I remember correctly, it has a switch inside of it. I forget what the switch was, but i think it was for UHF or VHF setting. But, you have to open the unit up. I have one with my CM4228. That's the best I can do, being in an apartment, with no balcony.

Another note: maybe the outside antenna legislation re-introduced into congress, may help. "Look for Vermont independent Senator Bernie Sanders to reintroduce a DTV rooftop antenna subsidy bill as early as Tuesday, when the new Congress is scheduled to be officially sworn in." according to B&C magazine, from Jan 5, 2009.

"Time is of the essence, since the bill would help pay for a rooftop antenna to help some folks retain a TV signal after the switch to digital on Feb. 18, 2009."

I would love to see a community antenna at my place, but remember I was told to get an engineer involved. They have not moved, since the FCC and WNWO-DT did a study, outside of course. I feel that doing the study outside invalidates the results, since TV's are inside... and no matter what wall I relocate the TV to, it will never be "line of sight," to the Toledo DTV towers. SO, I'll give Detroit, MI my revenue and viewing habits. The worst station, currently... WTVG... the station I never watch (associated with KTRK "abc13")... too much news and weather drama. Then comes WNWO-DT is the second hardest, which I only watch the now bankrupt RTN (Retro Television Network) I never watch NBC or "America One" (replaced "Weather Plus," since NBC purchased "Weather Channel")

Besides, Detroit gives me more options. "This," owned by MGM and soon "Dot2 TV Network" out of Columbus, Ohio are and soon will be newer options, Via WDIV 4-2 and soon 4-3.

Also, Detroit has all of the major networks, where Toledo does not, unless you have cable... then they drop a few networks.

Detroit TV stations are the clear winner in this.

If moving/metal traffic was not in the way, I was in line of sight, there were a community antenna, I would watch Toledo's stations more. Well, other than WTVG's dramacasting... that ABC/Disney forces them to do.

I'm not so sure it's going to go smooth. WE WILL HAVE PROBLEMS!!! I also worry about the poor, elderly, and recently displaced workers... who didn't pay into the FCC's system to have no signals that are consistant.

It's not just those who are getting shafted... It's all of us taxpayers who really are, since this is not what we asked for.

Too bad NBC didn't pick this up as a "Fleecing of America" story.


Another note, just to clarify:

WDIV, also known as "Local 4" is on Buckeye Cable, but is blanked out, where other Detroit STV (standard, as in 2-0, 7-0 and 50-0) stations are NOT blocked out.

As you also can tell, Buckeye Cablesystem is missing a few other STV stations, such as 20-0 (WMYD), 31-0 and 48-0 (WPXD), 38-0 (WADL), 56 (WTVS) and 62-0 (WWJ). If you look at the Detroit TV listings, you'll notice a few high power tv and DTV stations missing from this list.

Now they probably will not get those as DTV either, since there is no contract for those. As an over the air receiver of DTV, I get ALL OF THOSE. The only DTV stations I cannot get from detroit... WXYZ-7-1, 7-2, 7-3 along with WPXD 31-1, 31-2, 31-3 and 31-4.

NOte that Ion (not WPXD, but national feed) is only on Buckeye's "Higher pixel/higher price" service, where you need their converter to get it...which is more a month, even with a DTV or an HDTV. ($24.99 per month, not a "life line" service).

Not one single DTV station from Detroit (less than 60 miles from Buckeye's Angola Road (1/2 mile east of Reynolds Road) antenna's. With antenna's at least 100 feet in the air, that makes the reception better...and the 55 miles, if not slightly more, seem pointless. So for some reason, unknown to Toledo and its NW Ohio and SE Michigan customers, they are not carrying those DTV channels (ATSC), but carry the STV (NTSC) ones, even on the higher pixel/higher cost service.

You can understand what I mean by Googling "Buckeye CableSystem" and looking up "channel lineup", which is clearly on their site.

The point of this, to clarify the above... that Cable is missing a few major networks, versus my over the air.

This can come in useful for those researching what you will and will not be able to see.

For "over the air" TV networks, Antenna... at least in Toledo.... is the clear winner. Cable here does not give you access to all of the TV networks, English, Spanish or otherwise.

Well, I discovered last night that KVHP has started HD broadcasting on the full power stick that was used to broadcast the analog signal. They had a major malfunction with the analog transmitter a couple of weeks ago, and acquired a lower power transmitter to get back on the air. I am guessing here, but I think may they just decided to curtail the analog, and go ahead and install the digital transmitter. I am glad to see it go up myself. I do not know what ERP they are broadcasting at this time, but I did write them an e-mail asking that question. I will post here if I find out anything.

mary... the cat lady:

KVHP-DT channel 29 (30) is on the air at the fully authorized 1,000,000 watts. An application was filed yesterday for a License to Cover.

mary... the cat lady:

KVHP filed an app with the FCC today requesting to end analog broadcasts immediately. They will surrender their channel 29 license.

mary... the cat lady:

Locally, KITU-TV will be the only station to end analog broadcasting early, witht the exception of KVHP-TV which you already know ended the analog broadcasts late last year after a catastrophic transmitter failure.
Kitu will end analog broadcasts on 4-16-09. There is no word as to wether or not they will commemorate the occasion with special programming or not, nor what time of the day they will turn off the analog transmitter.
I will post here is any information is forthcomming.

mary... the cat lady:

I got an e-mail back from the KITU general manager which stated that there would be no commerorative programming at this time to end the analog broadcasts. The GM stated that they will turn off the transmitter at Midnight on 4-16-09.

mary... the cat lady:

The new 800 foot KBTV tower is built, and the antenna will probably be lifted up to the top on Tuesday. Too bad for me that it will not happen on Monday, as I am off that day and will probably miss it. I wish I could go watch, but alas...
The transmission line is installed into the transmitter building, and we should have KBTV-DT up and running at full power I hope within a few more days, and we won't have to wait until June 12.

mary... the cat lady:

According to an e-mail that I got from Chris Pruitt, the GM at KBTV this afternoon, they will fire up the 1,000 KW transmitter on May 11.
It has been a long time coming, and I wish them well.
