Waiting for the dust to settle before committing to an HD Radio transmission system? This should help.
Nautel is the first transmitter manufacturer to implement the interface.
The ARC Plus is the logical next step for anyone looking to interconnect sites, or simply make the leap to IP-based control.
After a power surge knocked WWBN-FM off the air, the manufacturer shipped and installed a new transmitter to Flint, MI within days.
The Nautel NV20 is a solid-state FM transmitter capable of running in analog, digital and hybrid modes. The footprint of this box is amazingly small for the power levels attained.
The company was founded on June 18, 1959, and introduced its first product: the first broadcast cart machine.
The 5-year warranty is being offered on all NV Series FM and NX Series AM transmitters purchased in 2009.
The all-in-one audio processor, stereo encoder and FM exciter received a Radio magazine Pick Hit Award at the 2008 NAB Show.
While he was at first reluctant to consider Armstrong because he was not familiar with the company's products, Terry Suggs' extensive search showed that Armstrong offered the best in pricing and packaging. The transmitter was shipped within a week and installation was seamless.
The first difficulty in accommodating increased IBOC sideband levels is that, because of the higher peak-to-average AM component of the IBOC carriers, the transmitter must be derated from Class C saturated FM operation.
Early in the 1930s French engineer Henri Chireix devised an ingenious method of modulation that he named most appropriately out phasing. It was based on the result of combining two out-of-phase voltages. This produces a fluctuating signal voltage that varies in amplitude as the audio signals change. This voltage, after amplification, drives a power amplifier stage with properly amplitude-modulated RF.
WKNO-FM, an NPR member station in Memphis, began operations on April 1, 1972, on 91.1MHz with 40kW of effective radiated power. The station launched its HD Radio signal in the fall of 2007. Up to that point, we underwent incremental upgrades and adjustments to the original installation.
The FCC is auctioning what may be the most important spectrum allocations of our time. This portion of spectrum will be available as a result of the FCC mandate for traditional analog broadcast television to migrate to the new digital HDTV system by Feb. 17, 2009, specifically the portion previously occupied by channels 60-69.
There are many lists extant of precautions to take before working with high voltage pieces of equipment. Lethal incidents may be more often caused by completely unexpected circumstances than from pure, careless accidents.
A station's studio to transmitter link (STL) is an integral part of its mission-critical transmission system, linking the site that generates the program material to the transmitter location itself. As such, the quality and reliability of STL equipment has always been of paramount importance. One critical aspect of an STL system has historically been lack of contention in its use.
Harris has donated a high-power FM radio transmitter and digital exciter to the Southern Alberta Institute of Technology (SAIT) in Calgary.
With HD Radio, it's important to monitor and measure the time alignment and level alignment between the analog modulation and the MPS, and stations will likely want to monitor the RBDS on the analog channel along with PAD data for both the MPS and SPS. Fortunately, there are now multiple monitoring devices made specifically for HD Radio, and each of these devices gives the end user options about which parameters are to be measured, and how the device is to alert the user once a problem is detected.
The NAB AM Antenna Computer Modeling Seminar held at the NAB headquarters in Washington, DC, the week of Nov. 12, 2007 attracted 45 engineers.
Radio-engineering work is very involved with filters of one kind or another. The science of broadcasting depends on the correct passage of various frequencies through differing pieces of equipment. Some frequencies are in the audio range and others are in the RF domain.
In recent years, the introduction of wireless networks allows users to work anywhere within a defined location. The technology behind wireless networks changes almost yearly, but one thing remains the same: the antenna.
Tower lighting requirements, which are specified in part 17 of the Commission’s rules, sometimes come as a financial shock.
Simply put, the Collocom-2 is an easy-to-install, solar-powered device used to play an audio warning or safety message at a tower site.
A group of broadcasters, consultants and manufacturers have petitioned the FCC to allow moment method modeling of AM directional arrays as a ways to reduce the burden of taking field strength readings in determining coverage.
Take some time to ensure that basic legal and FCC rule obligations are met when taking over as the chief operator at a station.
WHK celebrates its 85th year this year, the original Media Touch system is revisited, and the next wave of radio listeners are listening to radio at all.
