Interesting. When did they increase the power to 70%? Last I heard, it was only increased to 50%, but was temporarily bumped up to 100% during the Super Bowl.

FWIW, my signal strength for KTHV-DT is 100%, so if they from 50 to 70% of full power I wouldn't notice it.....

When I posted on here that I was occasionally getting KTHV, someone here, I believe it was you arxaw, told me I should let them know it. So I sent them an email, and they replied they would bump up the signal 10% a week until I got a steady signal......

We exchanged emails a few more times, they went to 70%, it really didn't help much, so I decided to not bother them anymore......

It has probably been 5 weeks or so since I have communicated with them.....

The reason I get them occasionally may be due to atmospheric conditions. Last week, I was getting most of the Tulsa digitals with signals in the 90's.

Most of the time, the signal strengths from Tulsa range from 0-10....

Any chance for us to get LR on satellite if this significantly viewed clause goes through?

You can check when atmospheric conditions are best for distant OTA reception at:
http://www.iprimus.ca/~hepburnw/tropo.html
Best hours are usually evenings or early mornings before 10am. These are also the times when you may suffer from distant channel interference, too. Especially VHF channels.

The new satellite act may change the rules for distant locals and allow D* to carry the same stuff the local cableco carries. Even if you were able to get LR locals on satellite, they won't be in High Def for the forseeable future - at least not on Dish or DirecTV. They just don't have the bandwidth.

I noticed that the LR locals on DirecTV are only available in certain zip codes, not including the county just to our south, Searcy, despite the fact I think they are in the LR DMA.

Is that because the spot beam won't reach us up here? That might be a problem if significantly viewed DMA's are allowed in the future.

Arkie,
Just guessing here, but I thought the exclusions were based on ZIP Codes that were claimed by other affiliates like Fayetteville, Springfield, etc... But maybe it is a spot beam problem.

Go into your STB setup menu and check the signal strength for the following transponders on the 119° satellite (SAT-B). The new locals will be on:
23
25
29
31

Looking at the map at:
http://www.ulna.net/mapserver/dtv/view.html
it appears that the LR locals will likely be on either transponder 25 or 31. If you get high signal strength on those 2 xponders, you can just "move" to a LR address, or some other address that qualifies, and get the locals (SD only, no HD).

Here are my signal strength readings for those transponders:
23 - 20
25 - 100
29 - 0
31 - 100

signal strengths

23- 0
25- 73
29- 74
31- 86

It is cloudy and rainy today, so that might have some minor effects.....

That, or you might need to tweak your dish. I'm still getting 100s on 25 & 31, but it's not raining at the moment... only cloudy.

Arxaw,

How often do you get rainfade? I have been with D* for about a month and have the Phase III dish. I have signal strength in the mid-90's on 101 and all 100's on 119 except for 23 and 29.

It seems like I am losing signal everytime it rains. Last night I lost all channels (0 on all transponders) from about 7:00 to 7:15. It was pouring down though and when it slacked up, the signal returned. Maybe it is the same as when I had E*, but it seems like a lot. It has rained a lot however.

Shaneotool-I have been able to get a lock on abc at times with amplified bunny ears in hot springs, one night I was able to watch the 10:00 news and raymond on the digital channel, when usually I never get a lock. If you were to adjust your antenna, you may have a real good chance of locking in on it.

Shaneotool,
KATV uses a low power UHF transmitter coupled to a directional antenna in Redfield, aimed W/NW, mainly for the WLR crowd. There are people in downtown LR/NLR that can't get KATV-DT OTA. The engineers at KTHV at 8th & Izard Sts. tell me they can't even receive it with their outdoor antenna. It's doubtful the signal would reach to Harrison.... but hey, ya never know....

Speaking of OTA, here's an interesting article on new OTA tuners from LG/Zenith. New LG TVs with built in tuners, available this summer, will have the multipath problems licked, allowing reception with simple indoor antennas and no precise aiming.

arxaw-

Has AETN come in any better for you? I tried emailing them from their website to ask about the Arkdelphia transmitter, but it bounced back, do you have any contacts there. (Shaneotool is in Hot Springs by the way, Arkie is in Harrison, who on the best atmospheric day possible shouldn't be able to receive KATV)

Also, have you checked on Little Rock locals on D*? Just curious how they look.

KTHV can't pick up the low power stations because we receive using directional from Shinall. Even then we don't receive KARK well, also not seeing AETN yet.

A few more kilowatts from those transmitters would be nice.

70% power. exceeds the analog coverage area and is being received well outside of grade "B".

Digital transmission, 520 meters above avg terrain. VHF...

All hard to beat

I have never even seen a 'blip' on the signal meter from any station other than KTHV, who I can occasionally get...... still not consistant....

For what it's worth, I always get a 'watchable' picture from KTHV analog.

If it matters much, my elevation here in the Ozarks is 1,400 feet......

I'm seeing what arkie said above; this taken from woopig.net:

"DirecTV now has LR local channels
« on: Today at 08:34:29am »

--------------------------------------------------------------------------------
Free for 60 days, then $3 per month thereafter. You must have the new multidish system. Channels are on their actual channel number (KATV -7, KARK - 4, etc)."

Hmm - wonder if them saying must have multidish means they would come in, in HDTV?

No, DirecTV has no HD locals via satellite. With current MPEG2 compression, they just don't have the bandwidth for local HD. For the forseeable future, you'll still need an OTA antenna for local HD.

The LR locals are on the new DirecTV 7s satellite, located at the 119° orbital position, instead of the main sats' 101° slot. An 18x20" multisat dish and "multi-sat capable" STB are required to pick up the 101° & 119° sats. Existing D* customers needing to upgrade can call DirecTV Customer Retention at 800 600-8977. If you ask nicely, they'll schedule an equipment upgrade at no charge.

nj829,
AETN.....!!! After mucking with my large lowband VHF roof antenna + VHF preamp and getting nothing but dropouts, I gave up on that antenna. It must be in a dead spot for channel 5.

Next I tried a homemade ½-wave dipole antenna I had previously made specifically for KTHV-DT channel 12. It's basically 2 coat hanger wires, cut to ½ the wavelength of channel 12. The two wires are screwed to a small block of wood with a 300-75 ohm balun and short coax attached to the VHF input of a CM 7777 V/U preamp. I stuck it up in the attic and it LOCKED onto KETS-DT's 1kW signal at a rock steady 69%. No dropouts at all, except during lightning or when the dishwasher is cycling. Lowband VHF (chs 2-6) digital channels seem to suffer from impulse noise much worse than highband VHF or UHF.

AETN has promised to pass PBS-HD programs in HD, but so far, all I've seen is 4 sub channels of SD programming. Perhaps they haven't gotten all their HD stuff up & running yet. There is also no PSIP program info yet, just the station ID and sub channel number.

Here is some AETN contact info.

WRT the standard def. locals on D*, I don't qualify for them. My D* service address is in a "white area" .... I've heard the locals look overly compressed and a bit soft.

rpqueen,
Welcome to the forum!

Don't forget KATV. At one point, I heard the downtown KATV studio couldn't even receive its own OTA signal. A few more kilowatts from all of these low power stations would end a lot of DTV frustration.

But you don't really expect that from Nexstar or Allbritton, do you?

Only your station, 16 & 38 seem to care about transmitting a decent DTV signal, and it is appreciated.

The locals for D* came online yesterday. They look really good compared to all other programming on D*. They look as good as the national networks IMHO.

A high-quality OTA analog signal would still be superior, but the locals are much better than Comcast. My only complaint would be KATV. It is soft and a tad bit washed out. I know it looks the worst of the E* LR locals as well. It seems that the number one station in the market could kick in some money to updrade their transmission equipment.

As long as I can remember, KATV OTA analog has always looked a tad blurry and washed out.

As for "the number one station" to each his own, but I couldn't disagree more. ABC has little programming of interest to me, and KATV's local news is too, uh, stuffy.....

I don't watch any ABC programming, aside from MNF. KATV always ranks number one in news and other rating measures for the LR market. That's all I meant. If you are consistently ranking number one, I think you would take more pride in your station. I guess they might say we're number one the way we have always done things. Who cares about spending more money.

Of course KARK is consistently last and continue to prove they could care less about improving the station.

Actually, they aren't consistently number one. KTHV is number one in morning and 10pm news ratings.

It's their owner, Nexstar that doesn't give a s**t about quality or serving the public interest of the Little Rock market. They are only in it for the money.

Nexstar thoughts as repeated by me: "But it just costs so much to put up a digital signal, and poor little KARK doesn't want to invest in something that limited people will receive and besides, the only show that is on NBC is 15 versions of Law and order and it just costs so much to put up a digital signal, those jerks at the fcc don't know what they are talking about....making us poor little stations spend money on new transmitters. we are actually mad about NOT doing a better transmitter so we can charge more money by multicasting QVC...." ***not official statement, just a generalization......

You can bet Nexstar/KARK will upgrade to full power when USDTV (or similar OTA multicast pay service) comes calling, looking for bandwidth. They'll probably continue to send out one 480i SD signal free and put HD on one of the MPEG4 multicasts on USDTV's pay tier.

Based on reviewing the FCC website, this is the information that I found. Forgive the formatting, but I have no idea how to make columns. The first number is the current operating level and the second number is the level at which the license was issued.

Operating Licensed

KETS 1 kW 2.1 kW
KARK 4 kW 989 kW
KATV 10 kW 750 kW
KTHV 27.5 kW 55 kW
KLRT 1,000 kW 1,000 kW
KASN 1,000 kW 1,000 kW
KVTN 10 kW 725 kW


What I am wondering is the differences between the total power output that the stations are licensed for? Is KTHV at 55kW significantly less that everyone else because of VHF compared to UHF? Why would KATV license 750 kW compared to the other UHF stations at 1,000 kW?

Also, why would a station choose to broadcast such a weak signal compared to licensed output when other stations such as KLRT and KASN are using full power. I assume it saves electricity or did the station install a smaller transmitter than would normally be used to save money on equipment.

Just curious. FWIW, KARK and KATV are pathetic with their current power levels. Also, if everyone ever begins using full power, obtaining signal should not be a problem.
