Most UHF antennas on the market have been designed for an upper limit of RF69. I doubt many were re-tuned for an upper frequency of RF51, and certainly none have been made / designed for an upper limit of RF36.
I'd bet many sold are still tuned for Upper limit of RF83!

Sounds similar to the "LX" network that NBC is launching.

Say it ain't so! This is one of the best OTA stations with some really fantastic foreign detective shows! One of my most watched channels along with PBS!


Hopefully someone else will pick them up.

No one will pick them up because they are ending their OTA service...
https://mhznetworks.com/mhz-worldvie...tal-streaming/

My guess is they are ending their C-band OTA service to the 26 public television stations that were their affiliates, which most likely is due to $$$ of having a C-band feed.

All is not lost, as they explain they will still be available, but only over the internet and you will now have to pay $ to watch them. A seven day trial and then pay up.

They ended their C-Band service a few years ago, since then they've been delivered to affiliates and sat providers via IP.

Thanks for the info KyL416. I wondered if they were doing IP after I posted that. I have been a C band/Ku band user for 15 years and am noticing a lot of the longtime C-band services leaving that broadcast medium for IP/fiber. Those that still do satellite TV as a hobby are seeing it shrink away.

Nothing new has been filed outside of a recently granted extension of their current RF 21 STA until July.

MHZnetworks left the air before only to return when their business plan did not work out. They may or may not stay off the air this time too. They may just be playing a game to see if they can find a more lucrative offer than what PBS was giving them....... which was probable peanuts.


It is a niche product they are selling.

I have a question that goes back to analog. How did they have WNBC on channel 4 and WNYW on channel 5 without interference?

There's a 4 MHz gap between RF 4 and RF 5:
RF 4: 66-72
RF 5: 76-82

I see. So, even on more sensitive tuners it wasn't an issue?

Yes, Channel numbers "essentially" are not the relevant information, it's the actual frequencies that matter ....
For example, there's the 4Mhz gap mentioned above, between 4 and 5 ...
But, between 5 & 6, there's essentially No Gap ( 76-82, and 82-88) That's why historically they wouldn't allow chs 5 & 6 in the same market, but 4 & 5 were fine ....
There's a Whopping 86 MHz gap between Chs 6 and 7 .....

To be precise, full power TV stations on adjacent channels (except 4/5, 6/7, and 13/14) had to be at least 35 miles away from each other in the analog era. Full power co-channels had to be at least 160 miles apart. Some VHF stations (back before UHF became profitable in the early 1980's) were "short spaced" to as little as 140 miles, but TV station owners needed to jump through hoops with the FCC to get those approved. In contrast, the FCC is allowing full power co-channels in ATSC to be packed in as little as 90 miles apart.

Interesting stuff. I wonder why back in the day NYC was allocated channel 5 instead of channel 6. It seems the latter would have offered more space on both sides.

There was also VHF channel 6 in Schenectady, NY (WRGB-TV) and New Bedford, MA (WLNE-TV).

Yes, but channel 5 first signed on in 1945, 2 years before channel 6 in Philadelphia, 9 years before WRGB moved to channel 6, and 18 years before WLNE signed on.

I never really though about the frequencies. I thought maybe there was some kind of "filter" or something at the transmitter site to prevent interference. I literally had no idea on that one. I live in the Philadelphia market south of Trenton, NJ. As far as NYC tv, the only channel I actually picked up from there is WABC post digital transition. I have more luck with WLNY and WLIW during tropo months. During the analog days, there was a time I picked up most NYC stations as well NBC 30 in up in CT.

They may have moved, but some time back, WVIT-TV (NBC) channel 30 of New Britain was on channel 35. Then and now, their site is Rattlesnake Mountain in Farmington, CT. CW 20, PBS 24, ION 26 and FOX 61 all transmit from there, too. (Channel 20 is now on channel 33, where CBS 3 of Hartford had been.)

AKA the FM broadcast band, which is why you could get the channel 6 audio carrier back in the day with your FM radio tuned to 87.9

In Vienna we sit, in late night cafe. Straight Connection, on T.E.E.

87.7 and in the 5 boroughs of NYC you still can do so because of WNYZ-LP which is operating as a franken-FM station:

I used to enjoy the silent movies that were shown on channel 6 WNYZ-LP, with Charlie Chaplin and Buster Keaton, but I am no longer able to tune in that station. I recall that the FCC did not approve as the video and audio were totally unrelated. What video are they airing now? How are they able to stay on the air? Won't they be forced to switch to digital only at some point?

Thanks for the interesting post.


According to the Wikipedia article on the station: "On June 29, 2011, the FCC canceled the license of WNYZ-LP and deleted its call sign". So, no more video signal. It looks as if the station had planned to switch to digital on physical channel 49, but the construction permit from the FCC expired. It also look as if the station operated as an analog FM audio/digital video hybrid for just over one year, presumably on physical channel 6, with 1.1 as the video virtual channel number.

That license cancellation was a clerical mistake on the FCC's part, which is why that section of the article is titled "Accidental license cancelation". It was quickly reversed and they have since been granted another digital flash cut construction permit which doesn't expire until 2023.

The FCC is still deciding on the final fate of the Franken-FM stations after 2021 and is considering letting them continue to broadcast an analog audio signal as an ancillary service.

Angry WABC OTA 7-1 compression quality

Hello, new here, if there's a better forum for this please let me know:

Just wondering if anyone else with WABC OTA ch 7-1 has noticed how poor their picture quality is compared to other OTA networks. It's practically internet video. They are compressing significantly more than necessary.

The website below suggests in the technical details for WABC that their bitrate is quite low, as low as 5 Mbps (less than DVD and Netflix), vs other networks using >10 Mbps, which would explain it. I'm not sure how they determined that but would be curious to know.

rabbitears.info/market.php?mktid=1

Just wondering who / what dept I would contact at WABC or ABC to do something about this. It's lame watching big events at this quality and is a perplexing choice for a flagship network in their own city. I'm looking forward to the Academy Awards but watching with "classic RealPlayer quality" is going to bug me. : \

Part of the issue is that ABC uses 720p - I know this is a circular debate but for non-sports content, I think 1080i has a much better quality for news and drama content. But there's definitely something else going on - they must be using an ancient encoder, because there is a ton of visible MPEG compression to the point where it almost looks like I'm watching a moving JPEG.
