IMT DragonFly Takes Flight

IMT Solution’s new DragonFly COFDM transmitter.

How often have you said, “I wish I could have been a fly on the wall,” when it comes to a meeting or a private conversation? Reporting ethics aside, the sentiment is understandable.

GatesAir Announces Yearlong Celebration of 95th Anniversary


GatesAir's Mason, Ohio, headquarters prepares for the company's 95th anniversary.

GatesAir’s Mason, Ohio, headquarters prepares for the company’s 95th anniversary.

GatesAir is celebrating the company’s 95th anniversary in business this year and plans to hold several events to mark the milestone, including the “95 Years Big Kick Off” event for customers at the 2017 NAB Show in April, the company announced today.

Other activities will include open houses at its Mason, Ohio, headquarters and Quincy, Ill., manufacturing center as well as receptions at IBC 2017 in Amsterdam and The Radio Show in September, it said.

The company will unveil customer contests next month to identify the oldest GatesAir transmitter and oldest working GatesAir transmitter installed today. The winners will be announced to the public in December, the company said.

The company traces its history to 1922 when Henry C. Gates founded Gates Radio and Supply Co. His son, Parker Gates, put the company on a path of innovation achieving several firsts in electronics and audio, GatesAir said.

Those early successes ultimately led the company to innovations in OTA radio and TV transmitter design, it said.

KTBS, KPXJ Add New DTV Transmitters

KTBS and KPXJ recently acquired Maxiva ULXT liquid-cooled UHF DTV transmitters from GatesAir, the company announced this week in a press release.

The stations, a duopoly owned by KTBS LLC in Shreveport, La., selected the Maxiva ULXT because of its high-efficiency, reliability and ease of operation, said Chief Engineer Dale Cassidy.

The solid-state UHF DTV transmitters, built upon GatesAir’s PowerSmart Plus architecture, also will provide a lower cost of ownership, he added. The new transmitters replace 15-year old tube transmitters.

KTBS (ABC), which broadcasts on UHF DTV ch. 28 (Virtual PSIP ch. 3), chose the Maxiva ULXT-80 to broadcast a multiplex of full power DTV signals at 52.2 Kw, including: ABC-HD (720/60p) on 3.1, The Local Weather (480i) on 3.2, and KTBS 24-Hour News (480i) on 3.3.

KPXJ (CW), which broadcasts on UHF DTV ch. 21, chose the Maxiva ULXT-60 to broadcast a multiplex of DTV signals at 34.6 Kw, including The CW on 21.1, MeTV on 21.2, Movies! on 21.3, and Antenna TV on 21.4.

NBCU Dallas O&Os Ready For Repack, ATSC 3.0 With New Transmitters

KXAS NBC 5 and KXTX Telemundo 39 in Dallas-Fort Worth  will add a pair of Rohde & Schwarz THU9 solid-state transmitters.

KXAS NBC 5 and KXTX Telemundo 39 in Dallas-Fort Worth are replacing their IOT transmitters with a pair of Rohde & Schwarz THU9 solid-state transmitters.

NBC O&O KXAS and co-owned KXTX (Telemundo) in Dallas-Fort Worth have selected a pair of Rohde & Schwarz 78kW solid-state UHF transmitters in preparation for the TV spectrum repack and ATSC 3.0.

The goal of the project, NBCUniversal said, was to supply twice the output power of the broadcaster’s old IOT transmitters to support Variable Polarization Technology (VPT), which NBCU selected for the stations’ new antenna.

The new R&S THU9 transmitters will continue to deliver 100% output power when switched to the ATSC 3.0 TV standard.

The new liquid-cooled solid state Rohde & Schwarz transmitters will replace the IOT transmitters currently in use.

“The liquid-cooled solid state design requires a fraction of the air conditioning required for IOT operation due to its extremely low heat dissipation in the building. This is a big factor for us in Texas during the summer months,” said Matt Varney, station VP of technology.

The R&S THU9 can be rechanneled without going off air to replace amplifier components or to make the change, something that makes replacing a transmitter prior to receiving a new channel assignment more palatable. With the tunable RFS mask filter, the system is ready for the repack, the stations said.

KOHD Makes Fast Getaway From 700 MHz A-Block

KOHD Bend, Ore., has relocated to a new channel assignment in the UHF band outside the 700 MHz A-Block of spectrum desired by wireless carriers.

Relocating from ch. 51 to ch. 18 was made quicker with the help of GatesAir, which built and delivered a new high-efficiency Maxiva UAXT solid-state transmitter on an expedited basis, according to GatesAir.

Minimal modifications to the station’s existing RF plant were necessary to accommodate the new transmitter, and no HVAC changes were needed.

KOHD is operated by Zolo Media and owned by TDS Broadcasting. Its new transmitter is a fully redundant air-cooled platform configured to transmit a single DTV channel at 4.3kW. Additional headroom is available if the station launches other OTA channels in the future, GatesAir said.

GatesAir Delivers High-Power Solid-State Transmitter

GatesAir (formerly Harris Broadcast) today announced delivery of what it calls “the world’s highest power digital TV solid-state transmitter” to an unidentified U.S. television station.


GatesAir has delivered a high-power Maxiva ULXT-80 ATSC transmitter to an undisclosed U.S. broadcaster.

The ATSC transmitter, the GatesAir Maxiva ULXT, produces 80kW of output and reduces the footprint needed by a comparable conventional transmitter, It also cuts power and maintenance costs, the company said.

Rich Redmond, GatesAir chief product officer, said solid state transmitters exceeding 20kW power output have been consider “cost-prohibitive.” However, the new transmitter  delivers “cost-effective over-the-air solutions for very high power applications,” he said.

Over-The-Air And Streaming Outweigh Cable, Sat Bill

Cutting the Cord

Since I’ve started reporting on TV broadcast technology in January, I’ve grown a deeper appreciation for the magic of broadcasting. So much so, that I’m writing today to say I’m tired of paying a high bill to my satellite provider and am ready to cut the cord.

This is coming from a guy who grew up with cable television. I only have memories of watching free, over-the-air television at my grandpa’s house, specifically, The Lawrence Welk Show on PBS.

I’m happy to announce that I’ve finally seen the light. Last weekend I went to Radio Shack and bought an indoor antenna which picked up 25 channels. The Denver-area broadcast transmitters are located in Golden where I live. I can actually see them from my balcony. While I’ll never watch a majority of the digital channels, the local ABC, CBS, NBC, Fox and PBS stations broadcast in crystal clear HD. After flipping between DirectTV and over-the-air, I can honestly say the HD looks better over-the-air. That’s because the signal isn’t as compressed.

Why am I doing this? While it did cross my mind that telling my readers about the decision would make them happy and perhaps slip me some great story tips, money was the main reason.

My last DirectTV bill was $115. That’s right — $115! It seemed like a good deal at first, and then they throw in a promotion for HBO (I love Aaron Sorkin’s The Newsroom) that includes Cinemax and Showtime. Three months later, the promotion ends and I end up paying regular price, but for what? One show that I really like? And of course, you can add more services online, but you can’t cancel those same services online. That requires a phone call. It’s not worth it.

Cutting the cord isn’t a perfect situation. I will miss watching live ESPN, but I can condition myself to catch up on the games that I care about online. I’m an MLB.TV subscriber so I can watch my hometown Detroit Tigers return to the World Series this year while living in Colorado.

I also have a few shows, including USA’s Burn Notice, that I enjoy to watch.

OTA TV-1For those cable shows, I plan on subscribing to Hulu Plus ($8/month) and upping my Netflix account (I know… I was paying $115 each month plus Netflix online for $8/month) to a one-DVD package for $10. Shows like The Newsroom are available on DVD at the end of the season, which make for a perfect binge-watching Saturday.

I won’t need a DVR, because if I miss a network show, like The Office or Modern Family, I’ll watch on my iPad. All four networks have an app that let viewers watch primetime shows 24 hours to 1 week after the show airs. Hulu and Netflix also stream those shows.

Let’s do some quick math:

  • I was paying $115 + $8 each month for DirectTV and Netflix, plus Internet at $30/month.
  • The antenna I bought was $25 and it’s going to cost me about $60 to cancel my DirectTV contract early.
  • Each month, I’ll pay $10 for Netflix and $8 for Hulu, plus $30 for Internet.
  • That’s $48/month for a savings of $105/month. That’s $1,260 each year.

Don’t expect my story to be out of the ordinary. I firmly believe more people my age (I’m 26) to follow suit. There was a report out this week that said 27% of U.S. online 18- to 24-year-olds watch five or more hours of video each week. 29% watch between one and four hours; 17% watch under one hour and 28% watch no video online. And according to PaidContent.org, Pay TV will actually shrink for the first time in history, from 100.8 million users in 2012 to 99.3 million this year. By 2017, it’s expected to drop to 94.6 million.

Just like broadcasters are adapting to consumer trends, cable and satellite companies will need to come up with a better business model. The bundle is unraveling. Consumers are sick of $100 cable bills.

Why pay all that money when local broadcasters are providing enjoyable, informative and great looking content free of charge?
