Performance evaluation
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.
NAB Trains Engineers at NAB AM Antenna Computer Modeling Seminar
The NAB AM Antenna Computer Modeling Seminar held at the NAB headquarters in Washington, DC, the week of Nov. 12, 2007 attracted 45 engineers.
RF filters
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.
Wi-fi antennas
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.
LEDs Are Here to Stay
Tower lighting requirements, which are specified in part 17 of the Commission’s rules, sometimes come as a financial shock.
Towerswitch Collocom-2
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.
New directional measurement techniques proposed
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.
Being duly diligent in station operations
Take some time to ensure that basic legal and FCC rule obligations are met when taking over as the chief operator at a station.
Sign Off
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.
BE Receives Multiple Transmitter Orders at NAB2007
Broadcast Electronics (BE) returned from the NAB convention with a number of transmitter sales, including some from Univision and Regent Communications.
BE HD Radio Transmitters Reach New Benchmarks
Broadcast Electronics (BE) reports that its line of solid-state FM HD Radio transmitters now exceed the previous benchmarks for output power and spectral performance.
LPFM and FM translators given new latitude
The commission has always been subject to political influence—as an agency created and funded by Congress, this is to be expected—but a blatant rule override to accommodate a politically connected illegal operator is discouraging to the honest broadcasters.
A Foundation for the Future
In its most basic description, this project entailed the addition of a 40 feet by 60 feet space attached to an older, steel-framed transmission facility, but the story extends far beyond the basics.
The path to upgrading
From finding land to filing a Form 302: an overview of the steps for completing an upgrade.
Open Mic: Steve Fluker
The Surround Sound Audio Task Group's latest effort is a paper that discusses surround on radio. Steve Fluker, co-chairman of the group, explains the paper's details.
The HD Radio Network
The advent of HD Radio is requiring the broadcast industry to take a closer look at its station's networking system and infrastructure. Minimizing network-related
Nautel V5d
WXPR chose Nautel's V5d for transmitting its HD Radio signal via the space combining method.
Wireless delivery alternatives
Exploit the latest wireless technologies to enhance the listener experience. After all, the terrestrial-based transmitter is only one of the possible delivery systems that radio stations can use.
Living with your license
Your new or latest station license has arrived. How you deal with it can have a huge effect on your future.
When it's time for a new transmitter
A transmitter is a major capital expense and will usually see a long useful life at the station. Unless necessitated by a crisis or change in facility,
The search continues
In the summer of 2003 we began our search to find the oldest transmitter in daily use. We received some submissions directly from stations, while others
