WJFK-FM Launches HD Radio Quadcast
To make the concept of an HD Radio quadcast a reality, WJFK established an IP-based distribution system to push signals from the three remote stations to its studios.
The coming of HD Radio to WKSU
WKSU had a major decision to make: Either add 5,000 square feet onto the broadcast center building or complete the installation of IBOC technology at its non-IBOC stations and further enhance the network with the implementation of multicast channel and program-associated data capabilities for each station.
Broadcast Electronics Discontinues Marti PNP, Offers Trade for STX LP
Discontinued parts have forced the manufacturer to cease production of the popular transmitter.
Field Report: Harris HPX
It appears Harris did some serious homework on this transmitter. The controller is like nothing I have ever seen before.
Nautel to Provide 18 Transmitters to Argentina
Radio Nacional de Argentina will use Nautel NX25 AM ttransmitters in locations throughout the country.
Broadcast Electronics Selects Transmitter Contest Winner
Entercom's WMMM in Wisconsin will receive new BE STX LP based on its winning application of an older BE transmitter located in cornfield.
Nautel Expands Support Services with UK Parts Depot
The new depot will house a parts inventory to be held for same-day shipments from Nautel's London-area depot.
Are you ready for an HD Radio Power Increase?
Waiting for the dust to settle before committing to an HD Radio transmission system? This should help.
Nautel Adds Axia Livewire IP-audio to Transmitters
Nautel is the first transmitter manufacturer to implement the interface.
Field Report: Burk ARC Plus
The ARC Plus is the logical next step for anyone looking to interconnect sites, or simply make the leap to IP-based control.
Broadcast Electronics Breaks Service Record
After a power surge knocked WWBN-FM off the air, the manufacturer shipped and installed a new transmitter to Flint, MI within days.
Field Report: Nautel NV20
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.
Broadcast Electronics Turns 50
The company was founded on June 18, 1959, and introduced its first product: the first broadcast cart machine.
Nautel Turns 40, Extends Warranty for 2009 Purchases
The 5-year warranty is being offered on all NV Series FM and NX Series AM transmitters purchased in 2009.
Ecreso Ships Next FM
The all-in-one audio processor, stereo encoder and FM exciter received a Radio magazine Pick Hit Award at the 2008 NAB Show.
Field Report: Armstrong X-1000B
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.
Higher-powered Sidebands
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.
Tennessee Turnaround
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.
Forgotten modulation methods
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.
Radio broadcasting and 700MHz
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.
A break from Tradition: Using IP for an STL
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.
Don't become a statistic
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.
Harris Donates Transmitter to SAIT Broadcast Training School
Harris has donated a high-power FM radio transmitter and digital exciter to the Southern Alberta Institute of Technology (SAIT) in Calgary.
