Digital Transition Answers



Tracking Transition in Tulsa

July 28, 2008 2:24 PM

Here we are, 205 days away from the end of full-power broadcasting here in the U.S. Today I thought we could blow our way on over to the Sooner state of Oklahoma to see what’s happening on Tulsa time.

KTUL, KOKI, KMYT and KEGB have constructed their final DTV facilities.

KTUL, the ABC affiliate, on analog channel 8, has moved to channel 10 for its digital signal, and will stay there. KTUL has a maximization application pending for a final effective radiated power of 15,000 watts with an antenna height of 567 meters above ground.

KOKI, the Fox affiliate, on analog channel 23, will stay on UHF channel 22 for its DTV operations. KOKI has an ERP of 1 million watts and an antenna height of 355.7 meters above ground.

KMYT, the MyNetworkTV affiliate, on analog channel 41 is broadcasting on its final DTV UHF channel 42 with an ERP of 900,000 watts with an antenna height of 355.7 meters above ground.

KEGB, an independent station owned by Oral Roberts University, on analog channel 53, will continue to broadcast the digital signal on UHF channel 49 with an ERP of 50,000 watts and an antenna height above ground of 205 meters. KEGB is the only Tulsa licensed station that does not broadcast from the antenna farm southeast of the city. The KEGB tower is located a little southwest of the center of town.

KOED, the PBS affiliate, on analog channel 11, will move from its current licensed UHF channel 38 back to channel 11 for its final DTV resting place. The channel 11 antenna has been rebuilt, and the new transmitter line has been installed on the tower. There is an application pending with the FCC for an ERP of 35,000 watts. The new digital transmitter has been ordered and is under construction with a delivery date of some time in August. Installation of the transmitter will follow soon after delivery. Testing of the new transmitter also will occur in August. KOED will continue its analog broadcast until the transition date and then will start operation of the digital signal on VHF channel 11 with an antenna 499.9 meters above ground.

KWHB, an independent station, on analog channel 47 and now broadcasting the digital signal on channel 48, will revert back to channel 47 for its final DTV operations. KWHB has a maximization application pending that will add 139,328 people to the coverage area when the final facilities are built. The KWHB antenna will sit atop the tower at a height of 434 meters above ground.

KJRH, the NBC affiliate, on analog channel 2, has a lot of work yet to do. In September, KJRH will apply to the FCC for a “special temporary authorization” to reduce the analog power and use an antenna that is mounted on the side of the tower for auxiliary service to continue broadcasting the analog signal, with a target date of December for initiating the lower power. KJRH shares the tower with KOTV. After the auxiliary service begins, the channel 2 and channel 6 analog antennas will be removed from the top of the tower. After removal of the analog antennas, new digital antennas for KJRH, channel 8, and KOTV, channel 45, will be installed. A new digital channel 8 transmitter was ordered and was expected to be delivered this month. The new digital antenna will be delivered in September. KJRH should begin to operate its channel 8 transmissions on Feb. 20, with an ERP of 15,900 watts at an antenna height of 588 meters.

KOTV, the CBS affiliate, on analog channel 6, will follow a similar plan to KJRH’s. The KOTV transmitter has been delivered and a December installation date is expected. KOTV will end up on UHF channel 45, with an ERP of 840,000 watts and a height of 532.4 meters high.

So that is the timeline for the Tulsa area. You can make your plans for the transition, and I hope all goes well for everyone.

Do you have any idea on the overall status of channels getting prepared? Have you heard of any TV stations and the potential for them to not be ready in time?

mary... the cat lady:

Hi Jesse,
There are 1,759 full power television stations in the U.S., and as far as I know, all of them are broadcasting a digital signal of some power at this time. I have not heard of any that are still broadcasting analog only. HOWEVER, there are many that have not built their final DTV facilities, and there are many that are still broadcasting on a very low power under a Special Temporary Authority granted by the FCC.
For example, KVHP-DT the Fox afilliate in Lake Charles, La. is broadcasting a low power signal of .2 KW (200 watts) effective radiated power (ERP) on a Special Temporary Authority granted by the FCC. That is a micro signal. For a contrast, our low power local Fox afilliate K36ID in Beaumont, Tx. is transmitting an ERP of 15KW (15,000 watts).
KVHP-DT has a construction permit authorized by the FCC to transmit 1,000 KW ERP. But in their construcion permit extension request, they claim that there is not room in the transmitter building to place both the analog and digital transmitters. Therefore, they are requesting the FCC to grant an extension until after the transition for the final DTV facility. KVHP will turn off the analog transmitter on Feb. 17, 2009 and then remove the analog transmitter from the cabinet, and then install the digital transmitter.
KBMT-DT channel 12 in Beaumont is broadcasting a digital signal on temporary channel 50 right now. They have requested a construction permit extension to continue on channel 50 for 30 to 45 days after the transition to remove the analog trasnmitter from the cabinet, and install the digital transmtter for final DTV facilities on their final digital resting place, channel 12.
The odd thing is that KBTV-DT in Port Arthur needed to find a different tower to broadcast the digital signal from because the analog tower was "severely overstressed" and to weak to support the additional digital antenna and equipment. So they are going to move to the KVHP tower, and their digital transition report states that they will have their full facility up and running by the end of December. They are moving to the KVHP tower in Louisiana... the same location that KVHP claims that they have no room to fit both of their transmitters... I wonder where the KIBTV transmitter is going to go??? Unless they were to build a new transmitter building, then surely they would build it big enough to fit both the KVHP and KBTV transmitters wouldn't they?
Anyway, yeah, there will be a lot of stations that will have a lot of work left to do after the transition. But one thing you can be certain of, full power broadcasting will end on Feb. 17 of next year no matter what... except maybe along the Mexican border if Kay Bailey Hutchison has her way, and the border stations get a reprieve until 2012.

Greg :

How soon after the transition date, will most stations broadcast their digital signal at full power? I am in the middle between Dayton, OH and Indianapolis. I live in town, there is a lot of trees and buildings around me. I was surprised, when I borrowed some ones digital tuner box, I was able to get some station with rabbit ears, better than I was with analog. So, I am thinking with an outside or inside larger antenna might work and possibly get either Dayton, Oh or Indianapolis, In Channel IN.

mary... the cat lady:

Hey Greg,
Sorry it so long to answer your post. i was doing some research on your stations.
Some stations are already broadcasting at their full power. Of course, as you know, some are not. As a general rule, most stations, if they were on a temporary channel, will be up and running at their maximum power within 30 to 45 days after the transition.
However, a granted maximization application gives a station 3 years to build out. It may take some stations that much time due to their financial situations or whatever.
Here are your specifics:
Indianapolis- WISH is broadcasting an effective radiated power of 19,500 watts (19.5 KW) but has an application that has not been granted as of yet to raise the ERP to 22.8 KW. WTHR will revert to channel 13 post transition. They have an application pending to transmit an ERP of 22 KW. They will cease analog broadcasts on Feb, 17, 2009 and take several hours to convert the transmitter to digital, end digital broadcasts on channel 46, and begin digital broadcasting on channel 13 as soon as possible on the 18th. WHMB is broadcasing the full power ERP of 163 KW. WFYI is broadcasting the full power ERP of 200 KW. WRTV is broadcasting an ERP of 898 KW but has an application pending to go to 1,000 KW. WDTI is putting out an ERP of 28 KW, but also has an application pending to go to 1,000 KW. And finally, WXIN is broadcasting the full power ERP of 700 KW.
Dayton- WDTN is broadcasting the full power ERP of 1,000 KW. WHIO is broadcasting the full power ERP of 1,000 KW, but has a modification application pending to place the antenna at the top of the tower. WPTD will move from the out of core channel 58 to the in core channel 16, and will have an ERP of 155 KW. WRTG has a granted construction permit to go to an ERP of 425 KW.
And finally, WKEF is transmitting the full power ERP of 138 KW.
A larger antenna will certainly help bring in the Dayton and Indianapolis stations better, and placing it ourside with a rotor and an antenna mounted pre-amp like the Channel Master 7777 will maximize your reception potential. Good luck, and let me know what you decide and how it turns out, OK.
I am here if you need any more assistance, but I may be out of town for a few days due to Hurricane Gustav. I don't know yet, but we are playing wait and see...

Greg:

Thanks Marry for all the info. I am just deciding whether to keep my limited basic cable, get directv family package or get an antenna. This explains why I got some Indianapolis stations with just an old pair of rabbit ears. The power out put of the station makes the difference. To bad they couldn't use cell phone towers to relay the digital signal to tvs for people who are way far away from any signal.

mary... the cat ladyMMRts:

Hi Freg,
You are so welcome. I am glad to help out. That is not a bad idea you have. It would take a while to sort things out with the FCC, but a series of repeater stations along a cell phone tower trail would solve a lot of the problems that we are going to have with the loss of analog transmission. It is definately somthing to think about...

Wow Mary!! That was an excellent answer to my question. Do you think there is anyway you can include a link to my converter box reviews page somewhere on your page here about the transition? I am trying to get the word out about the best converter boxes. You can email me at dtvconverterboxes@gmail.com if you are interested in considering it. Thanks! Jesse!

Jesse...

I can definitely attest to one particular box, that seems to sparkle, in comparison to the several that I have had. It's not on the DTV converter box reviews of Consumer Reports, but does rather well. It's not exactly making a perfect picture, but it helps more than other set top boxes. That Converter: TIVAX STB-T8. You see the STB-T9, it's younger brother, at or near the top of the list... but this one had "analog Pass Through", allowing me to see Canadian stations (Windsor/Stevenson/Wheatly, Onterio Yes, even Sarnia, Onterio too) and local "low power" and Class A stations. Yes, there is a difference between the 2.

Note that the Tivax STB-T9 doesn't have "analog pass through." So you have to watch DTV stations on your TV.

However, the link to the converter box listing:

I recently posted it in the "Preparing for D Day" comments section.

EmmGee-Ohio:

I wonder why it made me "anonymous?" It shouls have been "EmmGee-Ohio."

mary... the cat lady:

Hi EmmGee,
I don't know why it did that, but I am glad that you were able to establish that it was your post.
