For Sale: Harris Facility in Cincinnati
Cincinnati - Oct 15, 2007 - The building currently occupied by Harris in a northern suburb of Cincinnati is for sale. The 160,000-square-foot facility at 4393 Digital Way in Mason, OH, has an asking price of $16 million. The listing through Cincinnati Capital Properties notes that portions of the building are available for sale or lease.
Harris opened the facility in 1998 when Bruce Allan was president of the broadcast division. In 1999, Harris moved the broadcast equipment sales operation from Richmond, IN, to the Cincinnati facility. Harris still maintains some manufacturing facilities in Quincy, IL.
Harris recently sold its third-party equipment sales business to SCMS and opened various partner channels for its equipment and system sales.
HD Radio Delay Settings Get Low Marks in Southern California
San Marcos, CA - Oct 15, 2007 - Brian Beezley, an engineer in southern California, has a passion for RF. He has reviewed several HD Radio receivers and has posted his research on his website. On Oct. 14 and 15, he took advantage of his location to investigate a common setting for HD Radio: the analog/digital delay.
The hybrid-mode signals should be time-aligned to make the blend from analog to digital a smooth one. When the time alignment is not set properly, the blending can be an unusual phase-shifting effect during the transition to a complete dropout. The severity of the effect depends on the mismatch of the signals.
Beezley posted his results online, and the details are not complimentary to many of the stations he received. His post is quoted below.
I decided to measure the time alignment of every FM HD Radio station I could receive here in San Marcos, northern San Diego County.
A reasonable time-alignment error limit is a few samples (less than 100 microseconds). This will place any delay-induced spectral notches well above the midrange. I had hoped to list errors in microseconds, but after tuning around a bit I realized I had to relax my expectations. Below are the errors I measured rounded to the nearest millisecond. Positive means that the digital signal lags the analog. I drove a computer sound card with a Sangean HDT-1X in split-channel mode, with the analog signal on one channel and the digital on the other. I visually compared waveforms and used a cursor to measure large errors. To measure errors below 100ms, I used a waveform normalizing and differencing program.
Note that a timing error of just 1ms causes pronounced spectral notches to occur at 500Hz, 1.5kHz, 2.5kHz, etc., during the analog/digital blend. This is a gross artifact, easily audible. Shame on the lazy broadcast engineers at two-thirds of the stations listed below who can't be bothered to get their signal alignment anywhere close to being correct.
Freq Station Error 88.1 KKJZ 0 88.7 KQSC 40 89.3 KPCC 0 89.5 KPBS -50 89.9 KCRW 0 91.1 KDSC 40 91.5 KUSC -132 92.3 KHHT 0 93.1 KCBS 0* 93.3 KHTS 44 93.9 KMVN 0* 94.1 KMYI 298 95.5 KLOS 0 95.7 KUSS 3 96.5 KYXY 172 97.1 KLSX -2 97.3 KSON 1 97.5 KLYY 248 98.7 KYSR 0 99.7 XHTY 9972 99.9 KGGI 59 100.3 KRBV -103 101.1 KRTH -58* 101.5 KGB -4 101.9 KSCA 0 102.7 KIIS 0 103.7 KSCF 66 103.9 KRCD 0 104.3 KBIG 0 105.1 KKGO 0* 105.3 KIOZ 16 105.9 KPWR 0 106.7 KROQ -44 107.5 KLVE 0 107.9 KWVE 9
* Analog and digital signals are out of phase resulting in audio drop-out during blend.
The results may be indicative of a wide-spread problem. There are several known cases of stations not properly aligning their signals. Beezley's report is posted at ham-radio.com/k6sti/roster.htm.

Lectrosonics Receives Patent for Wireless Mic Technology
Rio Rancho, NM - Oct 1, 1007 - The United States Patent and Trademark Office (USPTO) has issued Lectrosonics a patent (U.S. Patent No. 7,225,135) for its Digital Hybrid Wireless technology. Digital Hybrid Wireless is used in the Lectrosonics Venue, UCR401, UCR411A and R400A receivers and the SM, UM, MM, UH and UT receivers. The technology is also backward compatible with earlier wireless systems from Lectrosonics and other manufacturers.
The Lectrosonics Digital Hybrid Wireless technology uses a proprietary algorithm to encode 24-bit digital audio information with no compression and low distortion into an analog format that can be transmitted in a robust manner over an analog FM wireless link, which results in a higher dynamic range.
A compatibility mode emulates the companding schemes of Lectrosonics 100 and 200 Series wireless systems using DSP.

Broadcast Electronics Recognizes Larry Cervon
Quincy, IL - Oct 16, 2007 - Broadcast Electronics will gather employees, customers, community members and radio icons on Oct. 26 to recognize retired BE President Lawrence J. Cervon for his lifetime of achievement and service in broadcasting.
For the October 26 recognition, Broadcast Electronics will dedicate a commemorative plaque to Cervon, marking the 30-year anniversary of BE's move to Quincy and kicking off the company's half-century mark. Radio veterans from all walks of the broadcast industry have been invited to the event, which starts at noon CST, as have the company's employees, many of who worked with him. Cervon will teleconference in from his summer home on Long Island, NY.
The event will be video webcast. Details are posted at www.bdcast.com/larry. Anecdotes and words of congratulations can also be posted at the same URL.
BE was founded in 1959 and Cervon was president of BE from 1976 to 1991. He took over when the company manufactured a single product: an endless loop tape cartridge machine. At the time, the company was located in the Washington, DC, area and Cervon moved it to Quincy in 1977 in order to take advantage of the area's skilled labor pool after Motorola vacated a facility there.
Cervon's service to broadcasting dates back to his days with RCA International, Westinghouse Electric and Gates Radio Company; Cervon succeeded Parker Gates as vice president and general manager of Gates Radio in 1967. In 1991, the National Association of Broadcasters recognized him for his 45 years of vision and leadership in the development of high technology broadcast equipment.

HD Digital Radio Alliance Renews Charter
Orlando, FL - Oct 15, 2007 - The HD Digital Radio Alliance, the joint initiative of radio broadcasters to accelerate consumer adoption of HD Digital Radio, has renewed the group's charter for a third year. The group's effort promotes the HD Radio rollout and works with stations in a market to determine multicast station formats to reduce format duplication.
The group also announced that it has committed an additional $230 million in marketing funds for 2008 to bring the total group commitment to $680 million. The "investment" sounds impressive, but the funds appear to simply be unsold on-air inventory on HD Radio stations. Part of the annual commitment now includes a portion of the weekly advertising time is to be given back to local stations to promote multicast content, local partnerships, events and promotions for their HD Radio stations, which further lessens the actual monetary value of the ad campaign.
The new charter also revises the method that partner stations use to select multicast formats. While the Alliance recognizes that format diversity will help consumer interest in multicast, stations will be able to change their multicast formats without Alliance review provided that the new format is not currently on the air in the local market at all.
The HD Digital Radio Alliance has also revised its two-year ad-free policy to allow companies to accept name-in-title sponsorships and limited sponsor mentions per hour on multicast channels.
Current Alliance members include Beasley Broadcast Group, Bonneville International, CBS Radio, Citadel Broadcasting/ABC Radio, Clear Channel Radio, Emmis Communications, Entercom, Greater Media and WBEB Philadelphia.

Sennheiser Offers Web-based Frequency Finder
Old Lyme, CT - Oct 15, 2007 - Sennheiser has unveiled a frequency finder tool that interfaces with the FCC TV broadcast database. The Sennheiser Frequency Finder (www.sennheiserusa.com/frequencyfinder) is designed to help wireless mic users quickly retrieve information about unused TV station frequencies based on a city or zip code search.
While the interface provides a convenient method of locating spectrum that is not licensed for a TV station's transmission in a given location, it does not provide information about any other use of what could be perceived as available spectrum. For this reason, users should also contact the local Society of Broadcast Engineers Frequency Coordinator (sbe.org) to verify that a desired channel is actually available.
