The Queen City is home to this year's NAB Radio show. Charlotte, NC, was also nicknamed The Hornet's Nest after General Cornwallis' description during the Revolutionary War. The show, no doubt, will do that name proud as it brings together a dizzying hub of new products and sessions set on improvement.
The show, running from Sept. 26-28, at the Charlotte Convention Center, will feature products from more than 100 exhibitors. Some may be familiar, some are brand new. Either way, this issue of Radio magazine guarantees to be an amazing resource. From audio software to codecs, tuners to transmitters, soundcards to databases, antennas, processors, and so much more, you will not be bored on the exhibit room floor. We have included here a plethora of products from some of the 2007 show's exhibitors.
Sessions this year are focused on reigniting radio. In this year's SBE Radio Engineering Forum, you will hear about topics such as VSWR measurements, of course HD Radio, and have the opportunity to be certified as a digital radio broadcast specialist. And there are plenty more sessions to attend, with topics including the infinite dial, podcasting and the future of radio. For a session overview, turn to page 54.
Perhaps best of all, the NAB Radio Show is a great place to meet new people and reconnect with old friends. The show is offering a variety of meet and greet sessions, most of which include food, which can never be a bad thing.
So get to the show early and stay late because this year promises to be a mecca of new products, education and networking.

Version 4.2 also includes predefined searches for Cps and move-ins so the user can quickly know the number of Cps in a market, identify overlapping signals from competing stations and determine when a CP will be a new move-in to a local market.
Inventory sales tool
703-818-2425; www.bia.com; email@example.com
Powerbidder: This program is scalable so that general sales managers with multiple stations can enter their rates on one bidding screen and apply them to multiple stations. Advertisers create auctions early in the week for ads they would like to run the following week. Radio stations bid against each other to win an advertiser's spots. The more auctions in which stations compete, the better their chances of winning auctions and selling last-minute airtime. With Powerbidder, sales managers enter the total number of radio spots they wish to sell across any number of stations, along with gross dollars per spot for each daypart. Powerbidder automatically determines which ads the stations should bid for to sell the most inventory.
AM audio processor
Optimod-AM 9300: Useful for AM shortwave, medium wave and long wave broadcasts, all processing is performed by high-speed mathematical calculations within Motorola DSP56367 digital signal processing chips. The processor's quick setup wizard walks the user through the setup process. A less/more knob customizes the processor's factory presets. Most of peak modulation control is performed within the five-band limiter, using multiband distortion-canceling clipping. An all-pass phase scrambler makes peaks more symmetrical to reduce clipping distortion and to allow better control of loudness. The analog input is buffered and immediately followed by an analog-to-digital converter. All processing takes place in the digital domain. The automatic gain controller compensates for operator gain-riding errors.

The technology will improve radio reading services for the blind, private channels for emergency operators and opt-in events sponsored by advertisers. The technology will encrypt content before it is transmitted over the airwaves, then decrypt it once the radio has received it and verified the entitlement rules.
Analog, digital translator
TRX-HD series: Designed to transition a translator station from analog-only broadcasting to digital, the TRX-HD receives an FM station's entire signal payload over the air, including its HD Radio digital component. The signal content is transferred to the TRX-HD transmit side for retransmission on the translator frequency. The TRX-HD10 provides 10W in the hybrid digital mode, the TRX-HD50 provides 50W hybrid digital, and the TRX-HD100 is a 100W hybrid digital translator. Higher hybrid power levels are achieved by adding an Armstrong solid-state amplifier.

207-947-8200; www.nautel.com; email@example.com
HD Now: This service provides HD Radio multicast broadcasters with a way to handle their programming and content needs. With one workstation, stations can create multicast programs by accessing a music library with more than 150,000 music titles or 100 professionally programmed channels in various music formats. Multiple HD Radio channels can be managed remotely from a central location to include customizable music, liner and commercial content that is relevant to each market.
FM scanning receiver
Band Scanner: The Band Scanner is a tool to evaluate FM broadcast band congestion and to log station identification parameters. The system is powered by the USB port of any Windows PC. Using it with a laptop is useful for gathering data from multiple points in the field. The Band Scanner generates a graph showing RF level vs. frequency for every station in the market. It then analyzes each carrier and creates a station list. Stations with an RBDS presence are further refined to show all the radio data groups being transmitted. Its interface is like a portable radio: It may be tuned manually through the receiver screen or by double-clicking a point on the spectrum plot or an entry on the station list. Spectrum plots may be saved as JPG or BMP files. The RBDS data error level is graphed in a separate window on the receiver screen. The program can be monitored with headphones plugged into a standard 1/8" jack.
