After the repack, my reception on various 33.x and 47.x channels seem to have a lot of 'judder.' Can't determine if it has something to do with repack or severe FM RFI that that also showed up exclusively in my home around July 30-31.


I suspect the neighbor on the other side of the duplex may have recently acquired an aquarium with a defective heater, there's an aquarium vacuum on their back porch. Noise bursts in 30 second intervals 24/7. RFI going through the house wiring that a portable radio picks up on the lower FM bands, especially near light switches.



Tried throwing all the breakers at the fuse box, but the RFI was still there. I have several UPS boxes, maybe a charge cycle, but they've never been a problem in the past.



The RFI has at least stopped for a while this morning, but I didn't get a chance to check OTA TV reception

Well, 33.x didn't move in the repack. 47.x did, but if you're having problems with 33.x they can't be repack related.

The RFI you're experiencing would ruin your VHF-Lo reception (if there's ever anything to receive there), but it shouldn't affect UHF all that much, and both 33.x and 47.x are UHF (RF channels 32 and 23, respectively).

So I'm guessing the 'judder' is something else; perhaps a problem at the stations. Does it occur on all subchannels or just some? Does 23.4 (Laff) or 49.2 (GetTV) show the same problem?

Does anyone get Grit in Dallas? It looks like it's running at 15 FPS on the Cleveland affiliate.

Newer is not always better.

Does it happen on all the subchannels? Are certain ones affected, like ones running in 480i? I wouldn't think a weak signal or interference would affect the frame rate. It's you either get a picture or you don't.

Thanks! Looks like a satellite feed or equipment issue here as the hourly ID faded in & out smoothly. Same station also carries Grit's sister networks Laff & Court TV and both of them look fine.

Something seems to have happened to 33 Wednesday. I had a network outage that day and lost my bandscan for most of the day, but after I got it working again, I could see 33's signal strength was noticeably weaker than it was before it went down.

Looking at schultdw's bandscan (which didn't go down), it seems to have happened around 4 AM Wednesday. I'm guessing 33 is on their auxiliary transmitter for some reason.

I watch Grit from time to time. Seemed okay the last time I saw it.

Sorry for the delayed response. I think it must have been related to whatever the interference was, which is apparently gone.
Visually, it looked comparable to a 10-12 frames per second frame rate. I could see the individual frames and especially with any kind of panning. I know judder is more like motion inconsistencies with converting frame rates, but that's what it reminded me of.

With the repack and the interference, I wasn't sure what was going on.

Anyone hear any reasons why KLEG dropped 44.6 and 44.7 from their lineup? Seems to have happened in the last week or so.

They've been gone since the end of July at least:

In case anyone is curious, their clock is now 894 seconds slow. Also, they've somehow messed up their PSIP generator so it's causing continuity errors on the base PID.

According to DABL's website, the new diginet will be launching on KTVT 11.3 on Sept 9th. Guess it won't be on KTXA after all.

And Court TV will begin November 1st on channel 33.3. But I still haven't heard where This TV or Decades will land.

I don't ever recall seeing a 44.7 but there was definitely a 44.6 many moons ago. It aired an infomercial network called DRTV (nothing to do with doctors though; just the usual infomercials). At some point it went to color bars and remained that way until KLEG finally dropped it.

Now, why they skipped all the way up to 44.8 when they added Faith is a mystery to me. It sort of sounds like they were reserving 44.6 and 44.7 for later, but why?

After the repack, KAZD's RF31 signal completely drowns out any chance for my north antenna to detect K31LQ, so I'm not sure if it's still on RF31.

As for RF28, I don't think K31LQ has moved yet. Their construction permit doesn't expire until 2022, so I doubt they'd be in such a rush to move (they haven't even submitted a progress report to the FCC yet). My north-facing antenna is just barely able to pick up KLEG, while my south-facing antenna is getting pretty much the same signal strength/noise numbers as you are. Guess we won't know for certain until K31LQ tells the FCC that they've moved, but I'll keep an eye on RF28 to see if it picks up not-KLEG via tropo.
Finally got up to Oklahoma last weekend. Within sight of the KXII/K31LQ tower I did a scan with my portable TV. Picked up KXII and KTEN but no sign of K31LQ on either RF 31 or RF 28.

So I guess they shut off their RF 31 signal but haven't lit up on RF 28 yet.

KAZD was on their backup transmitter for most of the day today. Looks like they just switched back.

Edit: They must be doing some post-repack work. They were at reduced power again today, and just switched back to full power again.

You are the only people making me feel not crazy. Is there still something wrong with 49.2 Get TV? I have rescanned my channel list over 25 times per Get TV and TIVO request and am still not able to view the channel. I have rebooted my TIVO as well. The same listings are on 47.7, but I can't get any picture there either. No one at either company seems to know what is wrong.

49.2 is working fine here. It's carried on KTXD's broadcast, but maps to 49.2 via PSIP. Do you get the other channels carried on that broadcast, 47.1-47.5 and 23.4?

Sounds like TiVo has their guide data messed up again.

I don't totally blame them. DFW's 49.x channels are a mess. Channels 49.1 and 49.3 are actually carried on KUVN's signal, while 49.2 is carried on KTXD's.

There isn't supposed to be a 47.6 or 47.7. KTXD programs 1-5 are 47.1-47.5, but program 6 is actually 23.4, and program 7 is actually 49.2: https://www.rabbitears.info/market.p...=42359#station

Since your 23.4 works, there's hope: TiVo apparently has that one mapped correctly.

I greatly appreciate your information and quick reply. Just knowing someone is getting the channel helps me know where to focus. I'll continue to work with the TIVO side. Thank you so much

DFW's last analog station, KNAV/22, is back to full power as of yesterday evening. For the past month or so they operated at somewhat reduced power, producing a snowier-than-usual picture.

Still no idea whether they'll make the switch to digital anytime soon.

KTVT has added DABL on 11.3, but no programming yet - just color bars and a test tone.

Edit: No service on 11.3 now. I guess they turned it back off until the actual programming starts.

What are your current three favorite sub-channels (that is, any channel not a ".1" channel)?

Mine are:
  • 8.2 AccuWeather
  • 8.4 Quest TV
  • 49.3 Grit

Cable Channel Choice is the only choice I want to make !!

I'd go with...
  • KXII 12.3 Fox
  • KTEN 10.3 ABC
  • KTEN 10.2 CW
Joking, I figure those don't count.

In all seriousness:
  • 8.2 AccuWeather
  • 27.4 H&I
  • 8.4 Quest

My favorite is 69.4....

Oh, wait; that's my own internal channel! You're probably wondering about OTA channels. For those, I'd go with:

  • 5.2 Cozi
  • 8.2 AccuWeather
  • 21.2 MeTV
  • 27.4 H&I
  • 47.2 Comet
  • 47.4 TBD

OK, I know that's 6 channels, not 3; but I couldn't really decide.

BTW, it looks like K26KC has been off the air since Thursday evening. I could never receive it anyway, but the signal strength readings on RF 26 were lower than usual, so I checked schultdw's bandscan, and sure enough....

Nothing filed with the FCC yet, so it could be just a brief technical glitch.
