News from the Convention
Bob and Tom to Host Marconi Awards
Morning show duo and four-time NAB Marconi Radio Award winners Bob Kevoian and Tom Griswold of the The Bob and Tom Show will emcee this year's NAB Marconi Radio Awards Dinner and Show.
Kevoian and Griswold created The Bob and Tom Show in 1983 as morning hosts at Clear Channel's WFBQ-FM Indianapolis. Over the years the show gained popularity and in 1995 was syndicated nationally by Premiere Radio Networks. Today, the program is carried by more than 140 radio stations.
Products from the Floor
Wheatstone Generation 8
This control surface offers four faders dedicated to call-in segments to provide an interface to four callers or remotes, each with independent caller feed, independent fader feed, user-selectable talkback communication and adjacent channel linking. A dedicated LCD display screen keeps the operator informed and in control. One CAT-5 wire conveys all the control from this surface to Wheatstone’s Bridge Router. Any system audio source (inputs or mixes) is available to any console fader or monitor pot (source visibility software controlled). Set destinations for mixes, aux sends and mix-munis feeds to anywhere in the facility. The surface can store and name switch and fader settings for each operator’s task and recall them by spinning an encoder and hitting a take button.
RF Parts Online catalog
A worldwide distributor for 34 years, RF Parts has released an expansion of its online catalog at www.rfparts.com. The catalog provides a listing of product information, product applications and product ordering with the company’s secure ordering system. The catalog lists a complete line of power tubes for broadcast, industrial and communications, including Eimac, Amperex, Taylor, Svetlana, RFP and Econco brands along with a full range of sockets through 20kW.
Moseley Associates Starlink 9003T1
This digital STL/TSL system for T1 circuits features new LAN connectivity for transmitting Ethernet to and from the transmitter site to support datacasting for HD Radio and RDS song title and artist data. A new six-port multiplexer and built-in CSU allows combining of these data channels with the program audio for direct connection to a T1 circuit making external interfacing equipment unnecessary. This system allows stations to transition the STL portion of their air chains to digital for IBOC. The T1 unit transports linear uncompressed stereo program channels at either 44.1 or 32kHz digital sample rates. Both AES/EBU digital and analog inputs and outputs and a serial data channel are built into the system. The SL9003T1 combines program audio with voice channels for telephones and data channels for communications and control for bidirectional transport over a single digital T1/E1 line, microwave radio or license-free 5.8GHz link.
Coaxial Dynamics 81095
This microprocessor-controlled, rack-mounted Watchman monitor/alarm measures and displays forward and reflected power simultaneously in 50V transmission systems. Using LCD displays, it also provides direct reading of VSWR. It is compatible with the company’s series of 7/8” to 61/8” line sections and will accept elements from less than 5W to 100kW full scale from 2MHz to 2.3GHz. Installation consists of the Watchman, a dual-socket line section and two elements for monitoring. The Watchman is supplied with two 25’ dc cable assemblies for connection to the line section and a 6’ ac power cord. An audible single tone alarm will indicate a system/transmitter malfunction. Relay contacts are provided for remote alarm and reset switching.
IBOC Takes Center Stage in Engineering Sessions
The technical sessions at the NAB Radio Show will focus on IBOC for all three days. The sessions will cover nearly every aspect of IBOC operation from the studio to the antenna. We'll provide a rundown of each day's sessions in this newsletter leading up to the convention.

Opening Reception on the Exhibit Floor
The exhibit floor officially opens with on Wednesday evening.
This on-air workstation combines the company’s Digilink Xtreme software and the Champ-6 workstation hardware. It features an embedded PC and audio playback system in a fanless unit. It has four stereo sound cards built in with play and record, analog and digital audio I/O and logic control for all four audio channels. It is Windows XP OS compatible with built-in networking for audio and schedule interfacing.
Westar Music Music library
This company provides production music for broadcast, corporate video and multimedia use. Westar offers production library music in seven primary categories: Sports and Corporate; Rock, Dance and Pop; Jazz and Blues; Easy Listening; Country and Western; Drama and Film Scores; and Specialty Music. Within each category are many music genres and styles. The website also offers resources to play audio demos for every CD and order a copy of a demo package, get a listing of the complete contents of its audio demo by CD number, track and title view its CD master list in order by CD number, and use the electronic cue sheet templates and music reporting information.
Superior Electric Stabiline TB1
The unit protects against damaging electrical disturbances, high frequency noise and high energy disturb-ances. Available in two sizes: 20A/ 45kA or 40A/65kA ratings. TB1 models use metal oxide varistors in parallel arrays placed at the input and output to protect critical loads from high-energy transient damage. They also use UL-recognized inductors and X and Y capacitors to filter error-producing high-frequency noise. Single-phase 120, 220 and 277Vac types provide three modes of protection. Split-phase 120/240 and two of three phase types provide six modes of protection.
Logitek Digital console enhancements
Several enhancements have been introduced for the Logitek digital consoles including a two-stage talk show delay, silence-sense capability, EQ and dynamics processing, input metering on every fader and compression metering on faders where activated. The Optical STL is available as part of the Logitek Audio Engine and offers 64 channels of bidirectional audio to be sent as far as 10 miles without data loss or compression. The system also provides intercom functionality that can operate as a stand-alone system or as part of a Logitek digital console. Other enhancements include a full X-Y router, mixed analog and digital I/O, multiple mix-minus buses, IP and multisite operation, and physical and virtual controllers.
