NAB Announces Engineering Achievement Award Winners
Washington - Feb 26, 2007 - Victor Tawil, senior vice president for Association for Maximum Service Television (MSTV) and Louis A. King, chairman of the board for Kintronic Laboratories, will be presented with the 2007 NAB Engineering Achievement Award during the NAB Technology Luncheon on April 18 at NAB2007. The awards recognize these individual's outstanding achievements and contributions in the broadcast engineering profession.
As senior vice president of MSTV, Tawil provides technology and telecommunication policy guidance to MSTV's 400-plus member TV stations. Prior to joining MSTV, Tawil worked at the FCC, where he held positions in the Office of Science and Technology specializing in the field of spectrum management, tropospheric propagation and system engineering. During his 14-year tenure at the FCC, Tawil worked extensively in the areas of broadcasting, satellite, wireless communications and new communication technologies, and served as a U.S. delegate on International and ITU Plenipotentiary Conferences and bilateral negotiations.
King has made contributions to the radio broadcast industry as an inventor, educator, consulting engineer and manufacturer. After receiving his first patent for a pulse transformer design, King served as an educator at Clemson College. He spent four years at the Radio Corporation of America, (RCA) where he was instrumental in the design of the first air-cooled 50kW AM transmitter at RCA and received the patent for the bistable multi-vibrator, which was better known as the flip-flop circuit commonly used as the basic switching device in early computers. King later began a consulting business that eventually led to the development of Kintronic Laboratories Incorporated, an RF equipment manufacturer with customers in all 50 states and over 100 countries.
Past recipients of the Radio Engineering Award include Radio magazine Technical Editor and SBE founder John Battison, Glynn Walden, Geoff Mendenhall and Bob Orban.

Products from the Floor
Day Sequerra M3
HD Radio monitor
The M3 contains three separate AM, FM and HD Radio tuners in a 2RU enclosure to monitor and alarm analog or digital (HD-1 through HD-8) signals. Each tuner's vacuum florescent display (VFD) shows station frequency, HD-1 through HD-8 PAD, analog RBDS data, signal strength and multipath. Status indicators confirm HD Locked, Multicast Available, Delay Bit Set and Tuner Alarm. Each tuner features balanced analog XLR outputs and a transformer balanced digital output. The analog outputs are level-adjustable via menu control, and each digital output remains present even when the M3 tuners are tuned to an analog station to provide a continuous digital output. Each tuner section is equipped with six dry, floating alarm relays that can be assigned to monitor RF carrier strength, audio level, OFDM lock, RBDS data stream, PAD stream, multicast available and delay bit. RF carrier and audio alarms can be set to activate at variable level settings, and all alarms can be set to trigger after a selectable delay. The audio alarm circuits use proprietary heuristic algorithms that cannot be fooled by pink noise or tones, and will generate alarms when real program silence is detected in HD Radio or analog broadcasts. An integrated front panel keyboard lock prevents unauthorized changes to the unit's settings.
Broadcast automation software
Enhancements to this automation software include a new talk button, which allows the user to insert a live talk segment into the log while still in automation mode. Users now have the option to use a condensed version of the Audio Library screen with the ability to drag and drop audio events into the main log schedule. The Compact Full Log Screen displays the full day's log in a wider view so more items are listed on the main on-air screen. Users can also now drag and drop audio from the full log into the main playback log. A cart-style Event Display changes the standard log based playback to static cart decks when users are in a Live Assist mode.
Barix Technology Low-latency software
Software for Exstreamer/Instreamer
The new software application for low-latency streaming in its Instreamer and Exstreamer IP audio encoding and decoding devices are based on the Barix Real-Time Protocol (BRTP). BRTP is specifically designed for radio stations and broadcast groups that wish to deliver a live signal from one studio to multiple Internet radio outlets without the delays associated with audio streaming. The streaming application reduces the usual 15 to 30 seconds of delay from PC-based encoders to about 200 to 500 milliseconds. The application can be used over a standard broadband infrastructure and public Internet connection using good compression ratios.
Global Security Systems USB Stick for Emergency Alert
USB stick for GSS Net
The USB stick plugs into any Windows PC supporting USB connectivity and connects the computer to the GSS Net Public Warning and Alert System. The thumb-size USB stick plugs directly into the PC and presents relevant alerts and messages. The unit is not dependent on an Internet connection and features a FM radio tuner built-in. The USB supports FM/RDS.

This 1RU rack-mountable source selector for compressing or limiting an incoming mic or line signal, along with selectable level metering and headphone monitor outputs. The compression ratio and threshold limits are fully adjustable via linear pots on the front panel. The threshold can be set between -30dBu and +20dBu. The mic input consists of an independent low-noise mic pre-amplifier for converting mic level signals to a line level. There are independent switches to control a high pass filter and to provide phantom power at 48V to the connected mic. The XLR-3 stereo monitor input volume control is fully adjustable via a back panel recessed pot, and has an additional 10dB gain increase via a switch on the rear panel for use with unbalanced equipment.
A 3.5kW model from its expanding range of ZX low-power transmitters, this unit will switch between digital, analog and hybrid modes on the fly, and can be delivered with one of three Harris exciters: the Flexstar HDX-FM, the Micro Max analog exciter, and the Digit CD exciter. For multicasting, it can be used with Ibiquity's Generation 3 exgine architecture, which brings the HDI-100 importer and HDE-100 exporter back to the studio and reverts the HDx exciter to a more user-friendly and reliable DSP-based operation.

Out and About in Las Vegas
Take the Bus, Gus!
You know about taxis. You know about the monorail. Don't forget about the hotel shuttle buses to get to and from your hotel to the Convention Center. There are 11 shuttle routes that stop at all the convention hotels. The buses stop in front of the North Hall at the LVCC and operate on the schedule shown below. The shuttles stop in specific areas at each hotel, so check with your hotel to verify the location, which is usually the tour bus or valet area.
The hotel shuttles run from the hotels to the LVCC from 7:30 a.m. to 10:30 a.m. Monday through Thursday. They run from the LVCC to the hotels from 4 p.m. to 6:30 p.m. Monday through Wednesday, and 2 p.m. to 4:30 p.m. on Thursday. Shuttles depart about every 20 minutes.
There is also a shuttle that circles the LVCC called the NAB Connector. This bus arrives about every 10 minutes and makes five stops: North Hall entrance, North Hall rear (by the Hilton entrance), Central Hall rear, South Hall Hall rear and South Hall entrance. It's 1/3 mile from one end of the LVCC to the other, and if you need a break to make the stretch, catch the NAB Connector.
Las Vegas has a city bus system as well, and four lines have stops near the LVCC. This includes the Deuce, a double-decker bus that follows the strip between downtown and the Las Vegas Factory Outlet.
Getting to the Airport
There's one more bus to be aware of. On Wednesday and Thursday, the NAB provides a free shuttle bus to McCarran Airport on a first-come, first-served basis. This shuttle runs every 30 minutes, and operates from noon to 6:30 p.m. on Wednesday, and noon to 4:30 p.m. on Thursday. The bus loads in front of the Central Hall.
ATI Group UADC-1
Analog/digital audio switcher
This analog-to-digital converter and switch provides 24-bit conversion with AES3 audio path insertion and interruption functions. The device may be used as a standalone A-to-D converter or as a way to insert stereo analog inputs into an AES stream via remote control. A sampling rate of 32kHz or 48kHz is selectable via internal jumpers. Front-panel LEDs display the audio present and clipping for left and right analog inputs, the input selected for output and the status of the device. Recessed front-panel gain controls for the analog inputs are included.
PTEK 1kW Transmitter
This transmitter is a single box 1kW transmitter with drop-down front panel for easy access to two replaceable 700W modules. The modular version will still be available.
