Houston UHF TV Repack

KTMD RF48 still on at a 8:45am check today 5/18. Color bars continue on RF22. The Telemundo Houston social media as well as TVAnswers.org still has May 18 as the switchover date, so perhaps the change will happen later today.
Checked at midnight but color bars still continued. Was surprised that they did not switch over until late in the day. I had thought they would have switched over during the early morning hours.

Came home at 2:00 PM from errands and RF 48 was shut down and everything transferred seamlessly (including the infamous slide on 47.3) on RF 22. I suspect that the switchover happened at 10 or 12 PM.

The encoder used to create the transmitted multichannel digital datastream is usually located at a station’s master control facility, not the transmitter site. It would appear the digital STL was simply moved from the old RF48 transmitter to the new RF22 unit, so nothing changed with the master encoder. The “47.22” test signal probably just involved a temporary (or backup) encoder. Obviously no one at KTMD is paying attention to 47.3. Surprised it hasn’t been leased to another programmer.

Sunday night before rescanning I did notice that my OTA set showed “unable to tune this signal” for 47.22 while also showing good signal strength! Of course after the rescan the 47.22 mapping was gone.

Anyone seeing KZHO (virtual channel 38) which had been on RF39? It would be the last “out of core” station left if it hasn’t moved already (to RF3.)

I only mentioned 47.3 to respond to the rant on post #37:

Speaking of KTMD subchannels, perhaps they will finally get rid of the silly 47.3 stream that used to have Cozi-TV. Still has a graphic advising a channel change that took place a year ago.

I think we can call it a day on the repack. All the full-power stations have moved to their new frequencies, so there should be no more activity in Missouri City. The LP station is a minor aberration.

True about the repack, but there will be more rescans in the future when ATSC 3.0 launches and the ATSC 1.0 channels are consolidated onto a few "lighthouse" transmitters. Houston is already announced as one of the first markets to get 3.0, but that is probably 18-24 months away at the earliest.

DFW is testing it now with three ATC sites..Cedar Hill, North Dallas and Broadcast Hill iirc.

True. T-Mobile has started installing 600 MHz radios and panels around Houston. They will probably have the entire market blanketed with 600 MHz LTE by this fall (that is if the merger doesn't cause them to hault permits).

KZHO transmits from the Chase building downtown, so no Missouri City tower farm activity involved here. If they are still on RF39 (not seeing them on my latest scans) it must be delays obtaining and installing the new VHF equipment.

That would be KSTR RF48 (but repacking to RF34) conducting the ATSC 3.0 tests with the main transmitter at Cedar Hill along with boosters on the same channel in Garland, Denton, and Fort Worth. The ATSC 1.0 version of UniMas is a 720p subchannel of KUVN.

I've noticed the larger panels on many cell towers lately, assuming they are the new 600 MHz antennas. Not sure if 600 MHz is going to give the big range improvement that T-Mobile likes to hype unless they are comparing to 1900/2100 MHz, not 700/800 MHz.

They are for both 600 and 700 MHz use. The difference with this heftier equipment is that it is capable of 4x4 MIMO and 5GNR-ready.

At&t is the other carrier using similar (but not the same) wide antennas for 4x4 MIMO in their Band 12, 14, and 5 carriers (that's a lot of lowband!)

Verizon should follow soon with similar lowband, 4x4 MIMO panels while Sprint awaits their merger fate.

Not sure if 600 MHz is going to give the big range improvement that T-Mobile likes to hype unless they are comparing to 1900/2100 MHz, not 700/800 MHz.
600 MHz is being touted as the spectrum that will bring parity with Verizon and At&t. While all carriers have low band spectrum, T-Mobile has the least out of all the carriers. T-Mobile has gotten by with only one 5x5 FDD LTE carrier while Verizon and At&t have each enjoyed a 10x10 FDD carrier + Cellular band fallback.

So indoor performance should see some improvement as far as speeds are concerned.
 
The repack has improved reception! Lower UHF frequencies are more conducive for broadcast TV. For instance, I had a poorer signal on KYAZ on 47 and sometimes it would have trouble locking depending on the weather. KTMD on 48 would also have some problems with poor signal and trouble locking depending on the weather also.

I've been holding off on buying a 4k TV until they come with ATSC 3.0 tuners. I told my dad to hold off on buying 4k TVs due to this, but could not resist Black Friday and bought a couple to replace his 10-year old sets a couple years ago. I'll probably buy a converter box when the technology matures and prices go down and buy a 4k TV (with a built-in 3.0 tuner) when my existing one blows.

Luckily Houston only has one phase (unlike most other DMAs) and it's one of the earliest (unlike the top 3 DMAs), so the rescan should be good for a while. Too bad we couldn't have everybody transition on April 12, like the big transition 10 years ago, due to the weather.

KZHO transmits from the Chase building downtown, so no Missouri City tower farm activity involved here. If they are still on RF39 (not seeing them on my latest scans) it must be delays obtaining and installing the new VHF equipment.

I was going to mention that also, but didn't want to get too long-winded in my last post. I think we can call it a day since they are a low-powered station and the mobile networks can start the 600 MHz service in the suburbs, where the signal is the weakest.

Somehow I am still getting a very weak signal from RF 39. There shouldn't be any stations in adjacent markets on RF 39. Perhaps they were covered by the extension into Phase 3?
 
According to the excellent Rabbitears.info site, KZHO has made its move to RF3, thus clearing out everything above 608 MHz. Anyone seeing KZHO?

The site has KCVH, KAHO, and a possibly to-be-resurrected KHLM as being off the air.
 
Receiving 3 rf solid today. Lightning? yesterday had it totally dead. also 5 rf. Side note: receiving 50 rf KBTX solid anytime on the back side of a small yagi. This freq is dead center on Tmo's INPUT (phone to cell tower) allocation. If their cell towers are as high as my antenna(100 ft) they will be clobbered until phase 9.

Thanks for the update. I haven't had any luck getting the VHF signals of KZHO and KTDJ to show up on any of my scans here in Cy-Fair, so I'm probably too far away from downtown. The UHF LPTVs from MC can be hit and miss. KBTX generally receivable here; they should be moving from RF50 (686-692 MHZ) to RF16 (482-488 MHz) in the Spring of 2020.
 
True. T-Mobile has started installing 600 MHz radios and panels around Houston. They will probably have the entire market blanketed with 600 MHz LTE by this fall (that is if the merger doesn't cause them to hault permits).

KBTX transitioned to RF 16 at 7:30 AM on Monday, Feb. 10 during CBS This Morning, about one month before the end of Phase 8. Odd choice of time with many OTA viewers having to rescan for this station when they come home in the evening after a hard day at work.

The good news is that the region is now clear of TV stations on the repacked band that blocked rollout of 4G LTE and 5G. The rollout on the north and northwest sides of town can finally start, assuming that the rest of the city has new cells on the reclaimed UHF frequencies.
