post #3091 of 3306
A station can be off the air (or operating below 85% of maximum power) for a maximum of 30 days without notifying the FCC. It sounds like KSMQ filed out of an abundance of caution.

jjeff: WEAU is currently on WQOW 18-3 and WLAX 25-2. I've heard nothing about permanent plans for a new tower, though I would expect them to rebuild the 2000 footer.

Trip - WEAU was something else. At 85 miles, DT-39 would come in unbelievably strong. It all went to hell when they moved back to Ch. 13.

I was speaking with gjvrieze and he thought that the 2,000ft tower limit was an FAA rule or something, but is no longer in place. Do you know if such a constraint is still in place? I always thought a 2500ft tower would be awesome.
post #3093 of 3306
Whatever the height of KVLY's tower is, that's the FAA height limit. KVLY has the tallest broadcast tower in the country, IIRC.

And I'm hoping that WEAU will rebuild on UHF rather than VHF. If they decide to do that, we'll see the paperwork filed sooner rather than later.

Looking for a little antenna help. I'm trying out an Antennas Direct Clearstream 2 antenna indoors. I'm able to receive the local ABC, CBS, and FOX stations bot not NBC (KTTC). Should I be using a different antenna, or am I maybe doing something wrong? Any help is appreciated.
post #3095 of 3306
KTTC is on Channel 10, which is VHF (while the rest are on UHF). You might just want to try a regular pair of rabbit ears, which would probably work better.
post #3096 of 3306
I've been doing more reading and it seems that my current antenna (CS2) is really designed for UHF, which is why I'm not getting KTTC. Should I be looking at getting an additional VHF antenna and combining the 2 signals somehow, or getting a different antenna that does both?

KTTC is a bit touchy for me with my outdoor, roof-mounted Clearstream 5. You might be happier with a Channel Master 4228HD, which has a clever VHF integrated element. It's not small, so check your measurements carefully.

This is the route I took to receive KTTC.
I have 2 homemade antennas in my attic. One for VHF, one for UHF, both fed into a CM7777 preamp.
(The Channel Master 7777 has 2 inputs on it, one for VHF, and one for UHF, or it can also accept a combined input)

Prior to that, KTTC was really tricky to receive with a UHF/VHF antenna.
Having separate antennas really seemed to help.
post #3099 of 3306
I am able to receive KTTC with a simple (indoor) rabbit-ears. The trick is placement; indoors the signal strength will vary greatly every few feet you move around the room, and there might be multipath interference. Just attaching them to the top of the TV may not work. I would not recommend an amplified rabbit ears as these do not usually work well (and they suffer from FM interference). I am using a simple $5 dipole rabbit ears from RadioShack, with horizontal dipoles tuned to a length of 29 inches across. You might want to try it before buying a larger, more expensive antenna.

KXLT just ran an ad saying MeTV is coming to 47.2 on May 16.
post #3101 of 3306
Yes it looks like Wiki has it listed also.

post #3102 of 3306
There is some info on their website http://www.facebook.com/pages/FOX-47...r/270244765230

There was a comment about RTV, but the response was RTV is going away. And MeTV is picking up most of the programming.

For those who have HDTVs, hopefully the picture quality of 47-1 won't noticeably degrade from the reduction of available bits.

There will be NO change of bit-rates for 47-1. FOX encodes the master HD feed at FOX HQ (not done at the local station, like nearly every other network) and sends it ready to air to the stations, with room for an SD sub channel preplanned into the mix.

I'm confused....is WEAU going to 25 long term, or staying on 13 long term?
post #3105 of 3306
Best guess is that they are applying to run a low-power signal while they build out the full facility. 35kw on UHF would severely decrease their signal coverage.
post #3106 of 3306
According to Upper Midwest Broadcasting site, WEAU plans to run channel 13 from their rooftop on an interim basis, but plans also to run channel 25 as a permanent placement. Apparently, even though the WEAU-DT-13 transmitter was only 20-odd miles from Eau Claire, many viewers there reported reception difficulties.
post #3107 of 3306
KXLT-DT did indeed go live with MeTV yesterday. Best guess is 1-1.5Mbps, barely adequate for 480i.

I watched some of Cheers last night, and was pleased to see that they kept the full introduction music, unlike some syndicated ones where it was severely chopped. I did not notice the video quality being poor during the program.

They must have changed some stuff around since when you looked at it. I am seeing 3-3.3Mbps this morning in the HDHR software.

Oh and by the way, MeTV is already on Charter clear QAM 83.4

Well, I guess 2000 ft height doesn't get you what it used to.

I'm curious about La Crosse and Wausau. Looking at the coverage map, it's like WEAU is abandonning them. KTTC's translater in Winona appears to reach LAX, and a station in Rhinelander hits Wausau, but those seem like large population areas to abdicate for a market the size of WEAU's.

I rescanned yesterday morning during breakfast and the TV found 47.2, but it was odd.

The TV acted normal when tuning in all stations except 47.2.

It would tune to 47.2, but once on it, the TV was very sluggish in changing channels away from 47.2 with the up and down arrow buttons on the remote.

It was also sluggish to move off 47.2 to go to the video inputs.

Later in the day it was behaving normally in that respect, but my DVD recorder's tuner had occasional stuttering/dropouts while watching. I suspect that there's some tweaking needed at the station.

Still, it's disturbing that a signal can affect the internal operation of a TV.

I'm curious about La Crosse and Wausau. Looking at the coverage map, it's like WEAU is abandonning them.

With all the problems related to VHF digital reception, I am not surprised. I am not familiar with the topography of Eau Claire, but I know that KTTC is my least reliable local station here in Rochester. All the others are normally trouble-free.

I don't think WEAU's CP represents their ideal. I think it is a stop-gap while they build out a new tower. 2000-ft towers take a year or more of planning and construction. And they are not cheap. The FCC has been rattling their chains about contracting broadcast television spectrum again, and I would be hesitant to invest heavily so soon after the digital transition. There is significant risk. LD translators for the fringe cities would make a lot of sense.
post #3112 of 3306
The 13 application is for an STA to get them back on the air. I read somewhere that WEAU is still planning to rebuild the 2000 foot tower.

post #3113 of 3306
WEAU's application says they do plan to rebuild at the Fairchild site, but they didn't say whether the tower would be as tall as the old one. It can't be much shorter, though, if they want any chance of reaching both Eau Claire and La Crosse from one stick.

The channel 25 translator was apparently in the works before the tower collapse. The application specifically mentioned indoor reception problems, which is not surprising considering the widespread problems with VHF High reception on indoor antennas and the fact that the Fairchild site is 25-30 miles from Eau Claire.

I have a working Zenith HDR230 free to good home. PM me if interested.

I spoke with their consulting engineer yesterday who confirmed they are planning to rebuild it to 2000 feet.

Good morning!

My brother's farm was hit by a tornado this past Sunday, and he needs to replace his Antenna. The insurance company said he could get any antenna he wanted.

He has a rooftop antenna, and is located one mile west of Harmony MN.

He has had trouble picking up 47 in the past, but gets most of the other stations (including the ones in LaCrosse).

Can anyone give me advice on what antenna he should pick out?

Thanks!

Brandon
post #3117 of 3306
If you would, could you go to TVFool.com type in his exact address and attach the results in a post?

Just typing in the zip code for Harmony, MN (55939), it seems that your brother is 20-35 mi from Rochester/Austin/Mason City stations (all off to the west), 40 miles from Lax's 19/25/31 tower and 55mi from Ch. 8 (off to the NE).

Is it possible you could get us a picture of the antenna he was using before? Also, are there any hills or tree cover around there?

There are two basic solutions - either you could get one antenna (or separate UHF & VHFs) and put them on a rotor. The other solution is to try a UHF antenna on a rotor and aim the VHF antenna straight at WKBT 8, then pick up KTTC off the back.

What exactly will the insurance company cover? One physical antenna or the replacement for the entire antenna system? (antenna, pre-amp, rotor, etc.)

Ideally, I'd try an Antennas Direct 91XG UHF antenna ($53) on a rotor. Then get an Antennacraft Y10-7-13 ($40) below the rotor (make sure you have >3ft spacing between the antennas) aimed at WKBT. Run the two antennas into a Channel Master 7777 Pre-amplifier ($60).

All of the stuff mentioned above is probably cheapest online. I'd suggest a place like SolidSignal.com

For mast, try 2" electrical conduit (available at Menards or the like). It's a lot tougher than TV antenna mast. For cabling, try RG-6 quad shield cable (you can get it by the foot at Home Depot or Lowe's). I like the Palidin Tools compression connectors (available at Menards). You can install them with two pairs of slip-joint pliers.

Also, make sure to install a ground block.

That setup should have signal coming out wazoo!
post #3118 of 3306
The key is rotor or no rotor. If he has or will install a replacement rotor, it should be easy. Without a rotor, it would be tricky, so I suspect he had a rotor.

The Antennas Direct V21 should do well for that distance, and is $61 or so from Amazon. Does both UHF and VHF. Winegard and Channel Master make comparable products for more money and lower durability.

Given the distance, I would steer clear of preamps unless his location is significantly below grade. There is such a thing as too much signal.

What type of tuner is he using?
post #3119 of 3306
He has a rotor.

Thank you for all the help, I'm assuming he'll go with the antennas direct v21

Thanks again!
post #3120 of 3306
I hate to be the party pooper here, but an Antennas Direct V-21 is NOT going to cut it for WKBT at 55 miles. Just to be safe and especially since you probably don't want a pre-amp if the thing is on a rotor, I would go with a Winegard 7698. It's probably one or two sizes this side of overkill, but hey... insurance is paying for it.
