Can anyone verify that KXLT moved to 26?

Any changes in signal level?

Yes, I can verify it has moved. I was out of town last week but when I returned yesterday it was on 26. Signal improved to a consistent 100% from 80% with my attic antenna/HD homerun setup in Rochester.

I haven’t been able to pick up KXLT since the lightning strike. I’ve rescanned several times and raised my antenna height 2ft. Using ClearStream 2Max with the reflector. My Tablo shows 5 full bars on all channels in the DMA, besides Fox not showing up at all.

Just for kicks, have you tried the tuner built into your TV?

Great idea, unfortunately still missing KXLT on my built in tuner. Strange that I can get 100% strength on KSMQ but nothing on KXLT. I’m itching to see the values when TV Fool updates their site. I’m LOS with -74 power pre repack. I’m guessing they dropped the transmitter height a few feet.

I’m in Mason City btw. If I get up to 5 posts I’ll link the TV Fool report. I’m about ready to go purchase and install a tripod mount before it gets too cold/snowy, if I lose 1ft of height current setup, KXLT goes from LOS to 1 edge.

Just looked up Mason City on TVFool. You're 30-45 mi from the transmitters. I'd try an RCA TVPRAMP1R on the antenna as it is now.

I would strongly recommend going with a better antenna setup and a preamp if you're going to go to all the trouble of putting up a tripod install - would give you way more "gain" than just mounting that anemic antenna a few feet higher. Might be a step overkill, but I'd do a Newark.com 30-2370 on UHF pointed right at 45° and a 30-2475 on VHF pointed at 53° into separate inputs of an RCA TVPRAMP1R.

I agree with Matt on the stronger antenna. KXLT’s coverage in Mason City is now very marginal according to the map on rabbitears. I think it was much better previously but I’m not sure how to retrieve the contour before the move.

I was down in Rochester over the Holidays. At two different locations (both within 10 mi and LOS to the tower), K25NK-D was nowhere to be found. Anyone know when they went off the air? I haven't seen anything filed with the FCC.

Took SNR levels at one location with an LOS to all R/A/Mc towers. The difference between old/new KIMT and KXLT channel allocations is within 1dB (both are sitting at about 31-33dB - by comparison, KYIN was at 28dB).

Mid to late October.

It was about the time that KIMT and KXLT switched frequencies.

I assumed many such low power stations would be leaving the air.

Has anyone else had reception problems for the past half of a week or so? As of Thursday morning, all channels were coming in perfectly. Starting Thursday night, the only channel we could receive was KTTC. I've tried rescanning channels and ensured the rooftop mounted antenna is still pointed in the correct direction, so this one has me a little baffled right now. Hopefully the problem is not on our end and everything will be back to normal soon.

Yes, while I still have reception for all, I’ve noticed some dropouts over the weekend with my dual attic antenna setup. The Rochester locals were previously pegged at 100% on my hd homeruns but now they are very choppy strength (except kttc which is still pegged). Very abrupt change after months of being very stable for me. Click image for larger version

Quincy going subchannel crazy soon

per rabbitears
KTTC adding CourtTV to 10-4 and Justice to 10-5
KXLT adding Laff to 47-3, Escape to 47-4 and Quest to 47-5

If it goes the same way it has been mentioned in other Quincy markets they will go live 5/1 except for Court which is 5/8

If it UHF channels only, have your leaves started to come back? Because of the shorter wavelengths, they affect UHF more than VHF.

Great news, Unclehocky! That really rounds out the Rochester Subchannel selection.

brendanjered - What kind of antenna are you running? Is it preamplified? Small seasonal variations and such are most likely to affect setups that have relatively thin signal level margins to begin with.

KTTC has color bars now for 10-4 and 10-5, saying coming soon. EPG for Court TV says May 8. EPG for Justice TV is listing the actual programs, no start date mentioned.

47-3,4,5 are active and have EPGs, but the picture itself is black.

So will duplicate KARE subchannels (Justice and Quest), and Chippewa Falls WEUX (Escape).

Which will be nice as I can't get non-local channels anymore since a power outage "degraded" the preamp at the top of my tower. Which I am no longer able to climb. So no more Packers games/coverage out of La Crosse.

Two more subchannels on KTTC??? That is already bit-starved. 1080I on 10-1 and 720P on 10-2 plus an SD. Confetti at the end of Nascar races in the winner circle is already pixelation city. Fast moving sports will be really bad.

And KXLT will be just as bad with two 720Ps and 3 SDs.

(If memory serves, the ATSC proposal called for one HD channel or multiple SD channels, not combinations of them.)

The encoding technology has improved greatly since ATSC 1.0 was first rolled out 20 years ago. Variable bitrates are giving stations much more room for additional channels.

A scan this evening revealed these additions:

10-4: Color Bars with the banner "Court TV Coming Soon 10.4"

10-5: Justice network, program playing



19-4: "CourtTV" PSIP tag, but signal too weak to play right now.

19-5: "Justice" PSIP tag, but signal too weak to play right now.



47-3: Laff network, program playing

47-4: Escape network, program playing

47-5: Color Bars with the banner "Quest TV Coming Soon 47.5"

Quest TV is now playing.


Court TV on 10-4 is the last one with color bars here. EPG continues to say beginning May 8. Color bars also mentions W34FC La Crosse, so it will also be on the translator there.

Long time no visit. Hope everyone is doing well. So like 10+ years ago via information from this thread I purchased the Antenna CM 4228 for my NW Rochester home. All worked great for many many years.
Last November I had to disconnect the antenna for a home improvement project. I just recently got it reconnected and notice that the 3.x channel strength is anywhere from 20's to maybe 40's and basically unwatchable. I've tried to skim through this thread and see if anything was new and boy howdy it seems some things have changed. So am I right to presume something was done with some of the towers? Do I need to adjust it my antenna or replace it? It's amazing how rusty one gets after 10+ years of not really focusing on a topic :-) thanks!

Obviously they moved from Ch. 42->24. Comes in with no issues on all my Rochester installs and measures about the same or a little better than 42 did (due to the lower frequency).

Recommendations would include double-checking all your connections, verifying proper aim, ensuring that your preamp is working and trying an LTE filter between antenna and preamp.

Thanks. Actually just needed a good adjustment / realignment.
