Renting AM Towers to Non-Broadcasters

Gary Cavell, Cavell, Mertz & Associates

The growth of cellular radio systems and other mobile communications technologies is creating worldwide demand for tower space. Many broadcasters overlook the AM tower as a valuable source of additional revenue. This presentation for managers and engineers alike provides practical, easily understood insight into the game of renting space on your AM station's directional or non-directional tower. Topics include liability issues, leasing "gotchas", planning for shared use, understanding each other's needs, FCC considerations, and (simplified) technical issues.

9:00 – 10:00 a.m.
Psycho Acoustics: Is Jim Loupas Crazy When He Says Branding with Sound

will Make your Radio Station More Successful?

James Loupas, James Loupas Associates


In today’s ultra-competitive market, branding with sound is a potent weapon in the radio broadcaster’s arsenal. Processing is part of it, but not all of it. Come learn the five ways you can make your sound a unique brand in your market. Questions and comments are always a part of this exercise.



10:00 – 11:00 a.m.
FM Boosters – Opportunities and Challenges

Stan Salek, Senior Engineer, Hammett & Edison

FM boosters have been in regular use for about 20 years. Over that time, many systems have been designed and constructed, with some notable successes, but also a number of disappointments. The key has been to adequately isolate the FM booster signal from that of the main station operating on the same channel in areas of population to be served. This workshop will cover the technical elements needed for successful implementation of FM booster transmitting facilities. Examples of both successes and failures will be presented, along with consideration of performance expectations when FM boosters are designed for IBOC digital radio compatibility.

11:00 a.m. – 12:00 p.m.
Advances In Remote Control Technology

Tony Peterle, Technical Support Manager, Audemat

Broadcasting is in the midst of a digital revolution. Advanced technology is spreading rapidly throughout the industry, from all-digital television to HD Radio to audio over IP to advanced all-digital audio processing and RF test and measurement equipment. One area that has lagged somewhat behind the technological tidal wave is remote facility control, but that now beginning to change. This workshop presentation explores the new technology being applied to remote facility control.


1:30-3:30

8:00 – 9:00 a.m.
Next Generation IP-based Audio

Tag Borland, President, Logitek


Network-aware professional audio equipment has a poor record of interoperability. Even if different models have the ability to communicate, the complex setup and varying parameter choices by manufacturers effectively isolate one model of equipment from another. This is reminiscent of the early days of networking in the computer industry.

Recently available protocols allow multicasting systems, like digital mixers, to automatically find and select the many settings required for network communication to work. Consoles can now find other audio equipment, negotiate communication methods and receive a list of available sources just by turning on the power. Some user groups have started requiring a minimum set of protocols in the networked equipment they buy. Now is the time to start planning for the coming change.

9:00 – 10:00 a.m.
High Bandwidth Capacity RF STL/TSL Connectivity

Jim Moody, Senior Consultant, James Moody Associates
Larry Miller, Senior Partner, Schwartz, Woods & Miller

This session will examine and present possible solutions for high bandwidth studio-to-transmitter, studio-to-studio and transmitter-to-transmitter connectivity problems. Modern broadcast data connections such as T1, DS3, OC3, and 100baseT Ethernet were not even contemplated when the FCC drafted the rules that govern STL connectivity. Those rules have not evolved with the demands of technology, and broadcasters are now faced with a connectivity dilemma that often dictates looking beyond Part 74 to Part 101 of the FCC rules.

10:00 a.m. – 12:00 p.m.
HD Radio™ Measurements Workshop

David Maxson, Managing Partner, Broadcast Signal Lab



HD Radio technology and its implementation require an understanding of measurements techniques not familiar to most radio engineers. Some of what will be covered in this special workshop includes: the HD Radio signal and spectrum, the HD Radio mask evolution, the current state of the rules, what is PSD and measuring PSD.




2:00 – 3:30 p.m.
The Embedded Exporter Technical Panel

Moderator: David Layer, Director, Advanced Engineering, NAB

Panelists: Dan Dickey, Vice President, Engineering, Continental Electronics Corp.
Scott Martin, Head of Data Systems, Nautel Limited
Ted Lantz, HD Radio Product Manager, Broadcast Electronics
Tim Anderson, FM/Digital Radio Product Line Manager, Harris Corporation, Broadcast Communications Division

HD Radio transmission equipment has recently advanced to the next level with the unveiling in April of the "Embedded Exporter." HD Radio stations use the Exporter to combine multicast audio channels and advanced data services along with a station's main audio channel into a format suitable for transmission. In this session, the differences between the previous generation of Exporter equipment and the new Embedded Exporter will be explained, with a focus on how this new technology promises enhanced reliability and a greater feature set while at the same time substantially lowering the cost of upgrading to HD Radio technology.
