V-Soft Seeks Beta Testers
Cedar Falls, IA - Mar 22, 2006 - V-Soft will unveil its new AM ground conductivity program at NAB2006. The program, with the working name of Conductivity, takes measured field strength values of AM stations and matches them to ground conductivity curves or partial curves. The program graphs the field strength values in this process.
Final output shows where the conductivity breaks along the measured radial. The graphs allow the user to create labels and otherwise provide user notes on the graphs. This program is a stand-alone program, but is most useful as a companion to V-Soft Communication's AM-Pro allocations program.
To volunteer to be a 30-day beta tester for the AM ground conductivity program, e-mail Adam Puls or call 1-800-743-3684.

NPR Labs Explains its HD Radio Signal Coverage Study
In 2005, NPR Labs developed signal logging units to aid in the mobile data collection of IBOC digital radio (and analog host) signals. By October 2005, digitized coverage data on more than 30 FM stations around the country had been obtained. A paper entitled "HD Radio Coverage Measurement and Prediction," by John Kean, Senior Technologist, NPR Labs, Washington, DC, was compiled and will be explained at this year's Public Radio Engineering Conference on Friday, April 21 at 10:45 at the MGM Grand. The paper describes the NPR Labs project to collect HD Radio signal coverage data and based on this data form a propagation model for the FM IBOC digital radio service.
Using a closed-back design for isolation, these headphones employ a large speaker driver (53mm) and feature rich bass with a frequency response from 5kHz to 33kHz. The headphones' soft padded ear cups swivel 180°. They use a folding design, dual nickel-plated adapter (1/4" and 1/8") and semi-coiled soft insulated cord with reinforced cable strain.
Netia Digital Audio Radio Assist 7.5 Modules
Digital audio software programs
The short message service module for the Radio-Assist 7.5 range of digital audio software programs uses mobile phone platforms as a new way to communicate interactively, allowing on-air talent to play interactive SMS and voting games with listeners. The Air-DDO module is spread over two monitor screens. The GUI simultaneously displays four broadcast channels and offers access to help and preparation tools, including a cuer, on-air monitoring, playlist modification, recording and production. The statistics tool allows users to measure and monitor the effectiveness of various elements of their daily broadcasts, including the number of times an audio clip has been played. This new tool automatically displays results per day, month or the user's period of choice. Multitrack XT is an editing tool for multitrack digital audio recording and editing. It offers time stretching, pitch shifting, noise reduction, noise gating, synchronization, stereo and multitrack broadcasting, support for CD audio engraving programs and import/export MP3 files.
Armstrong TRX-HD series
Analog, digital translator
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.
Inovonics Model 532
FM/HD Radio mod monitor
The company's first product manufactured under license for Ibiquity's HD Radio digital transmission system, the 532 measures parameters of the analog FM and the digital HD program channels, and includes a display of the occupied spectrum.
Logitek to Hold User Group Meeting at NAB2006

DRM: The Basics in 90 Minutes
For the first time at NAB, a panel of DRM front-liners will present how-to seminars for broadcasters (and anyone who is thinking about DRM implementation) called DRM: The Basics in 90 Minutes.
The seminars will be hosted by DRM members Continental Electronics and Harris, and will take place at their respective NAB exhibit booths. DRM seminars will be held on April 24, 25 and 26.
There is no charge to participate, but registration is essential. To book your place, e-mail the DRM Project Office at email@example.com.
DRM will also be on the agenda at the 60th Annual NAB Broadcast Engineering Conference. Two DRM presentations will be made in the Digital Radio Worldwide session from 10:30 to noon on April 24. The first relates to the use of DRM at higher frequencies, for local and regional broadcasting. This could be of particular interest in regions where FM spectrum is at a premium. DRM Technical Committee Chairman H. Donald Messer will present "DRM Progress in Developing a Capability in the Broadcasting Bands above 25 MHz."
The second describes some pioneering work on monitoring the performance of digital radio delivered on HF over wide geographical areas. Andy Giefer of DRM member Deutsche Welle will present "Digital Shortwave Reliability Analysed with Deutsche Welle's DRM Monitoring."
On April 25, John Sykes of the BBC World Service (a DRM member) will present a paper introducing a simple signalling system for AM radio. This system allows existing AM broadcasters to signal their station ID to a new generation of hybrid digital/analog receivers, thus keeping them on the "digital dial." Look for "An AM Signalling System (AMSS)" in the Emerging Technologies for Radio session from 1 p.m. to 5 p.m.

Peak SPL per pair is 115dB driven by a pair of 90W amplifiers for each driver. The 7260A features a single 10" proprietary driver with a 120W power amplifier, frequency response of 19Hz to 85Hz (+/-3dB), and delivers SPLs of 108dB at 1 meter.
MGE UPS Systems Network Management Proxy
Plug-and-play software for UPS
This plug-and-play software agent allows any of its Uninterruptible Power Supplies (UPS) to be interfaced with an Ethernet network at no extra cost. The Network Management Proxy (NMP) is useful for small UPS systems because it allows a UPS to be controlled over an existing network without adding a network management card and associated cost to the UPS. With the proxy software agent installed on a PC or server system that is connected to any MGE UPS via a USB or RS-232 port, users can monitor and manage the UPS remotely using a standard browser or a network management console. The NMP agent provides XML and Simple Network Management Protocol (SNMP) protocols and can be operated in standard secure mode or in Secure Socket Layer secure mode.
AES/EBU surround format
D.A.V.I.D. has implemented the newly standardized RF-64 surround sound format. In cooperation with broadcasters, the IRT and EBU staff, D.A.V.I.D. engineers developed this new specification. It is available as an upgrade to all customers. The file format is designed to meet the requirements for multichannel sound in broadcasting and audio archiving. It is based on the Microsoft RIFF/WAV format and WAV Format Extensible for multichannel parameters. Additions are made to the basic specification to allow for more than 4GB file sizes when needed. The format is transparent to the BWF and all its chunks.
Global Security Systems GSSNet
All-hazards digital alert system
This alert and notification system uses the existing nationwide FM broadcast infrastructure to provide messaging coverage and a proprietary messaging system that allows secured and encrypted data with layered and targeted messaging to personnel. Command and control centers are installed with full redundancy. Messages are transmitted from a FM radio tower to multiple receivers in the coverage area. Fixed-wireless substation receivers and wireless receivers are made available to be distributed to all counties and other jurisdictions throughout the state as defined by the authorities.
