    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
    Booth 500
    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
    Booth 1312
    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
    Booth 1404
    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
    Booth 1502
    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.
