Another Station Succumbs to California Fires
Lakeside, CA - Oct 26, 2003 - At about 4 a.m. on Oct. 26, the wildfire swept through the KECR property in Lakeside, CA. This fire started the evening before about 12 miles northeast of the transmitter location and has already moved another 16 miles west and east. Continuing winds, low humidity and drought conditions have aided the fire's spread.

According to Jeff Zimmer of KECR, the winds from the fire itself were strong enough to move a 5-meter aluminum dish that was stored on its back and flip it over. Five of the station's seven tower tuning houses were destroyed. One tower collapsed. The studio and transmitter buildings did not suffer any damage.

The station is currently on the air at 850W non-directional through one of two undamaged towers.
California Fires Damage Transmitter Sites
San Bernardino, CA - Oct 26, 2003 - The CGC Communicator, an e-mail newsletter from Communications General Corporation (CGC), reports that the wildfires burning in California have affected a shared transmitter site.

The transmitter site for KCAL-FM, KFRG-FM and KSGN-FM, which is located on the slopes of the San Bernardino Mountains about six miles due north of downtown San Bernardino, CA, was overwelmed by the fire on Oct. 25. The following is taken from the CGC Communicator issues 599 and 600.

KSGN reports that its emergency power generator kicked into operation at about 12:30 p.m. Saturday, and that at about 1:30 p.m. the station went off the air. KSGN is a non-commercial/educational station operating on 89.7MHz.

Bruce Potterton, chief engineer of KSGN, was the only engineer who managed to penetrate police lines and visit the transmitter site on Saturday. He reports that while all the towers are still standing with antennas apparently intact, the roofs of the broadcast transmitter buildings have been destroyed. Potterton was unable to view the condition of KCAL's transmitting equipment, which is presumed to be seriously damaged or destroyed, but did confirm the destruction of the transmitting equipment at KSGN and KFRG. Anything made of aluminum no longer exists. Furthermore, it appears as if an explosion had occurred inside the KFRG building.

As of Oct. 29, KCAL and KFRG have temporary low-power operations on the air from Box Spring Mountain, while KSGN has installed new coax to its still-standing antenna and plans to resume near full-power operations from its site soon. KSGN conducted on-air tests and achieved about 70 percent power on Monday Oct. 27 by using station's emergency power generator, which survived the firestorm.

Preliminary reports have raised some questions as to the structural integrities of the KCAL and KFRG towers.

Thanks to Communications General Corporation (CGC), consulting radio engineers, Fallbrook, CA, for allowing Radio magazine to reprint this information. Past issues of the CGCG Communicator can be read online at

Mexico Airs IBOC
Quincy, IL – Oct 28, 2003 - The first IBOC signals to air in Mexico were heard at 2:10 p.m. on Oct. 3 following the installation of a Broadcast Electronics (BE) FMi transmitter system at XHFAJ-FM Radio Alfa. The station is operating under an experimental license on its licensed frequency of 91.3MHz in Mexico City. XHFAJ-FM is owned by Grupo Radio Centro, the country’s leading radio broadcaster with 13 stations and the program supplier to more than 100 affiliate radio stations across Mexico.

The IBOC system is on loan from BE for testing purposes and to demonstrate the technology at the country’s fall broadcast convention. IBOC was compared to Eureka 147, XM Radio and Sirius satellite signals during the Cámara Nacional de la Industria de Radio y Televisión (CIRT) convention held in Mexico City the week of Oct. 5. Attendees listened to XHFAJ-FM’s digital audio through a Kenwood HD Radio receiver, also on loan for the show.

BE's HD Radio transmitter system remains in operation at XHFAJ-FM pending further testing and technical consideration by Mexico’s Secretaría de Comunicaciones y Transportes (SCT), which is expected to set national digital broadcast standards in the future.

On loan to XHFAJ-FM is a factory BE FMi 402 HD Radio FM transmitter, one FSi 10 HD Radio signal generator and two FXi 60 digital exciters. The BE FMi 402 HD Radio FM transmitter provides 1.5kW into an injector supplied by Shively Labs. XHFAJ-FM’s existing transmitter remains in service for the analog path and provides 16.66kW into the injector. The output from the injector is a combined 15kW analog and 150W digital into a master antenna system, resulting in 90kW ERP analog and 900W ERP digital.

BE supplied XHFAJ-FM with two FXi 60 digital exciters. One is feeding the FMi 402 HD Radio transmitter and the other is installed in the analog transmitter, allowing for synchronization of the two broadcasts. The FSi 10 and both FXi exciters are synchronized to a 10MHz master oscillator, which is needed for continuity of service in blended coverage areas.

ATI Expands Flexibility of System 10K
Horsham, PA - Sept 15, 2003 - Audio Technologies (ATI) delivered the first RM103 rack mount option for its System 10K to the Philadelphia local NBC affiliate Channel 10 for service in the new Lincoln Financial Field, home of the Philadelphia Eagles football team.

The RM103 expands on the flexibility of ATI's System 10K by allowing the use of as many as three additional modules in a 1RU space. ATI's modular SYS10K allows users to plug in up to 10 single-line, dual-line or microphone amplifier modules and distribution amplifiers and two dual redundant power supplies. Separate fusing and regulation in each amplifier module minimize localized heat build-up and yield the highest system reliability. All modules have front-panel output level adjustment and headphone jacks. Remote control is available via RS-232 or RS-485, and VCA options are available for remote gain control for mono or dual units.
ERI Promotes Tower Safety
Chandler, IN – Oct 27, 2003 – As part of an on going effort to promote tower safety, Electronics Research (ERI) has begun a comprehensive campaign to make ERI tower owners aware of regulatory changes, safety concerns and maintenance issues. ERI provides a range of products and services to ensure that tower owners are in compliance with the most recent regulations.

OSHA may soon require that tower safety climb devices be installed, or other positive climber attachments be used. If the tower does not have ladders and platforms in accordance with OSHA standards, warning signs must be installed. ERI now offers these signs along with other safety signs.

While tower inspection and maintenance is the responsibility of the tower owner, ERI offers all the resources necessary to meet this responsibility. For example, ERI can help tower owners adhere to the standard for inspection frequency described in the TIA/EIA-222-F Standard Manual. ERI’s Professional Service Team can aid with other safety concerns as well, such as wear and replacement of fiberglass insulator rods, corrosion of underground guy wire anchor shafts, and guy wire vibration issues. In addition, the Professional Service Team will assist with maintenance issues.

Lynx Studio Technology now Shipping AES16
Costa Mesa, CA - Oct 30, 2003 - Introduced last summer, the AES16 audio card from Lynx Studio Technology is now available. The AES16 192kHz multichannel AES/EBU interface is a half-size PCI card that provides 16 channels of 24 bit AES/EBU digital audio at a 192kHz sample rate, and works with single-wire and dual-wire AES devices. It is shipped with a hardware-based 32-channel digital mixer that is controlled by its own software application. Designed to integrate digital consoles, multichannel A/D and D/A converters, hard disk recorders, digital audio workstations and other digital audio equipment, the AES16 is compatible with Windows and Macintosh operating systems.

The AES16 is the first product to incorporate Synchro Lock, a proprietary Lynx technology, that allows the AES16 to output low jitter digital audio from severely degraded signals. This ensures bit-perfect digital transmission and translates into low distortion in signals converted to analog. The AES16 also acts as a format converter. Its on-board Lstream expansion port accepts the optional Lynx LS-ADAT 16-channel ADAT Lstream card, to combine ADAT Lightpipe signals with the AES/EBU I/O. Two AES16 cards may be connected for seamless routing of 32 channels of digital I/O. As many as four cards can be combined in a single computer for 64 inputs and 64 outputs. The AES16 is able to internally route 32 available channels to each of its 8 stereo record devices. Each of these channels can also be routed to any of the 16 output channels for zero latency monitoring. This allows the AES16 to function as a 16 input, 16 output cross-point routing switcher, for flexible monitoring configurations.

The AES16 mixer software for Windows and Macintosh (OS9 and OSX) allows all parameters to be set and monitored on the computer, as well as signal routing and level control for inputs and outputs. The 32-channel mixer also includes the ability to save and recall an unlimited number of mixer scenes, making the AES16 a virtual digital patchbay. Two models are currently available, the AES16-XLR and AES16.
