FCC Enters Consent Decree with KFMB-TV Over Captioning Fine

The FCC has entered into a Consent Decree with Midwest TV, owners of KFMB-TV in San Diego, canceling a $20,000 Notice of Apparent Liability issued after the station was accused of failing to make emergency information available to people with hearing disabilities during the October 2003 wildfire news coverage.

In the decree, KFMB-TV admits no wrongdoing, but would agree to an Emergency Visual Presentation Policy set for staff members that will be overseen by the News Director. The policies require timely Closed Captioning or open captioning of aired emergency information through any means available, including “handwriting on a blackboard.” The decree also requires KFMB-TV to make an $18,000 “voluntary contribution to the U.S. Treasury.”

The FCC also issued NALs to KUSI and KGTV in 2005 of $25,000 and $20,000 respectively. To date, those Notices have not been settled.

FCC Busts Oceanside Church

According to the FCC citation, the San Diego office received a complaint of a signal on 1610 kHz in Oceanside. On November 2 last year, investigating agent Bill Zears found on Canyon Drive a Part 15 compliant 3 meter long antenna, but a 30 meter ground system. The FCC named Iglesia de Dios Ebenezer ("Ebenezer Church of God") as subject of the citation.

San Diego HD-Radio Progress Report

Digital radio broadcasting seems to be catching on in San Diego despite the high cost of installation and low listenership. Ibiquity Digital Corporation, sole provider of the FCC-approved IBOC system, built into its growth plan heavy financial incentives, including lower or no license fees for early adopters. Large groups like Clear Channel endorsed the move to IBOC, too.

Ibiquity is working the backend, too. We’re beginning to see and hear commercials boosting HD Radio and mentions of commercial-free subchannels. And radios with digital capability are showing up at Radio Shack, Best Buy, and Fry’s.

So what’s going on in San Diego radio?

Here’s a table of San Diego HD-Radio stations, courtesy of Ibiquity:

89.5 KPBS-HD1 FM News/Talk/Info San Diego State University
89.5-2 KPBS-HD2 FM Groove Salad from NPR San Diego State University

I asked three San Diego engineering managers about their HD-Radio projects:

Leon Messenie, KPBS

When did you first hit air?

July 29, 2005

What is on your subchannel?

Groove Salad – KPBS’s secondary digital channel. Groove Salad, a 24-hour music station, is a partnership between National Public Radio and Soma FM; and the result is, well, “groovy.” (From our WEB site, not my wording)

Any notable project stories?

The one thing that sticks in my minds was the first morning we were digital. The newscast came up to the point where we cue the traffic report and there was nothing but silence…dead air…. It seems that none of us Engineering or Programming types thought about the newly induced digital delay in the analog signal. This is done to align the analog and digital program streams for a seamless switch between them. This delay is about 8 seconds.

So here is what happened: The Traffic service listens to KPBS-FM off air. When they heard their cue it was already 8 seconds past the real point when they should have started talking. This confused them so much they just stopped talking for the entire report. The Engineering cell phones lit up like a Christmas tree. Needless to say emergency orders for dedicated mix minus phone lines between KPBS and the Traffic office were installed. I am just glad the Traffic service did not have a helicopter….

Recommended receivers?

Not that I recommend them but we use the Boston Receptor HD desktop receiver. They work pretty well with an outside antenna.

Are you considering a closed service for your reading service?

In May 2006 KPBS-FM was part of a test with NPR to test what is being called the extended digital service. We put the KPBS Radio Reading service into this area and then compared the sound quality and reception to that of the analog Sub Carrier receiver. This test was presented at the IAAIS conference at a hotel in Mission Valley. The Mission or as we in radio call it Missing Valley hotel was the perfect place to test this. In a room with about 150 people we listened to first the analog SCA receiver. The sound quality was terrible and you could barely hear the KPBS Radio Reading Service. When we switched the room audio over to the audio from the digital feed the room of people just gasped. The sound was perfect. It was very cool to be a part of something that was such a success. Work is being done now to make this a closed system in order to broadcast Radio Reading Services around the country without violating copyright laws.

John Rigg, Clear Channel Radio

When did you first hit air?

The Clear Channel San Diego stations were on in May of 2006, with the exception of KGB and KOGO which were on in early 2005.

Any notable obstacles?

No two installations were the same, even though the application for HD is software written by Ibiquity, manufacturers integrate differently and apply their own GUI to the exporters and importers.

Any warnings?

Planning, Planning, Planning.  If someone has already done this in your group, ask lots of questions, no need to re-invent the wheel.

Recommended receivers?

I have a JVC KDR1 in the car. It’s a great radio, no RDS on the analog though. I’ve heard great things about the Sangean Component Tuner although I’ve not personally seen one.

Is your group adding more HD-Radio stations?

Clear Channel is currently adding stations to the digital offering. I’m not sure of the schedule, but hey, Tucson just did an install.

Eric Schecter, Lincoln Financial Media

 

What stations have HD-Radio broadcasting? What format?

KSON-FM has country on HD-1. We don’t have an HD-2 yet

When did you first hit air?

December 22, 2006, just in time for Christmas.

Any notable obstacles, funny stories, warnings?

Yes, several. The obstacle that was eventually overcome was getting the data to the Harris Flexstar Exciter from the studio where the Exporter (fancy name for a Linux box with soundcards) lives. We use 7 of 24 time slots in a T-1 Intraplex  multiplexer to accomplish this. It appears that the the module adaptors that present a 10 Base T interface only operate at half duplex. In the end, we used a hub rather than a switch at the studio end, and everything seems happy.

In the warning department, first some background: Our transmitter is a Harris HTHD+ and it utilizes a 4CX20000C tube biased AB1 (sort of) to make 18kw transmitter power output (TPO). The FM+HD signal combining occurs in the Flexstar Exciter. This is known as low-level combining. In order for the transmitter system to make spectral compliance, the exciter uses RTAC, or Real Time Adaptive Correction. While you can get away with some VSWR on a regular transmitter, a hybrid digital system really needs to have a flat transmission system (antenna, feedline, fittings, switches) to achieve optimal performance. We have work to do to optimize a system that is about 25 years old.

Recommended receivers?

I’ve evaluated the Boston Acoustics Receptor. With a good antenna, it’s a good performer. With a short piece of wire close to the radio, the display electronics tend to de-sense the receiver, and it’s as deaf as rocks. BA is now supplying folded dipole antennas based on NPR Labs tests. It receives both AM and FM. There are some good hidden menus for the experimenter in all of us.The price point for this fine sounding radio is $299.

I’ve also evaluated a professional tuner by ADA. It’s actually two tuners in one chassis, and is made for tech centers in the stations. It will do both AM and FM HD, displays RDS and HD PAD data, and is a finer performer. Price tag is about $3500.

Do you plan to outfit your other stations?

Yes, KIFM and KBZT.

Mike Prasser, CBS Radio

Which of your stations have HD Radio?

Currently neither of my stations in San Diego are broadcasting HD. We are looking at second quarter of this year for both. The HD2 formats have not been finalized.

Recommended receivers?

Most of the receivers on the market are good. The most exciting thing that I saw at CES last week was a company called Sideport. They have created a single HD chip that contains all of the components needed for HD with a much lower current draw for $20. Currently there are two chips needed one at $15 and one at $20. So this make HD Radio smaller and cheaper to make.

KSDS Gets FCC OK to Raise Power

(Disclosure: The author is employed by Bay City Television, San Diego-based programming, advertising, and marketing arm of XETV Tijuana)

The FCC issued on October 31 a construction permit for KSDS (FM), 88.3 MHz, to increase power from their current 3 kW vertical to 22 kW ERP vertical, upgrading the facility from class A to class B1. The station, operated from the campus of City College downtown, but transmitting from a tower at Mesa College in Linda Vista, has been operating since 2002 with 3 kW ERP vertical polarization after a compromise worked out with Fox Television affiliate XETV, channel 6 in Tijuana.

The latest CP approval comes as a surprise to XETV, which has fought the increase in power since 1995 on grounds that it creates a substantial interference zone since the stations are only separated by a minimum of 200 kHz between allotments, or 550 kHz between carrier centers. The stations represent a unique situation in the U.S., where a border non-commercial FM had protected a channel 6 TV signal broadcasting in English-language from Mexico. The new construction permit appears to change the crossborder relationship by declaring previous protections null and void.

The new FCC ruling says that previous international broadcast treaties do not specifically deal with the TV-FM interference issue, so the XETV signal has no rights to protection from U.S. non-commerical FM stations after all. At the same time, the order gave recognition to XETV public service efforts and ordered that KSDS broadcast its increased power in vertical polarization only. KSDS must provide a shallow null to the southeast, and they must remediate any known interference and report unsolved cases to local FCC inspectors.

KSDS intends to have its facilities ready for increased power by spring 2007.

Yuma Market First in Nation to Adopt New 12 MHz BAS Plan

The Yuma-El Centro TV market underwent a changeover to the new BAS 12 MHz per channel ENG microwave spectrum plan Friday, September 22, according to Robbie DeCorse, Chief Engineer at KYMA (NBC) in Yuma. He says that they “haven’t had any issues since the switch; it’s business as usual.

Meanwhile in San Diego, Nextel is working to get the necessary 75%
of the market under contract. Pat Hughes of Sprint-Nextel says that
they believe it will be next summer sometime before the switch takes
place here. He forsees Santa Barbara switching soon, then Palm Springs
and San Diego. Los Angeles will be last due simply to the sheer number
of people involved in the project.

Once the market has contracted for the changeover, there has to be a “caucus” to decide the exact swapover date.

Hughes encourages those who want to learn more to get updated information from their special website at www.2ghzrelocation.com.
