In early October of this year, MRN Radio, the voice of NASCAR, crossed the finish line by moving to its new studio facilities. While one advantage of this move was that the facility did not support a 24-hour on-air operation, it was not simply a move across town. The studio moved 500 miles.
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.
It's no secret that everyone feels pressed for time. Workloads are increasing while staffs continue to be cut. We are asked to do more, but we're not always sure how to get it all done and keep track of the steps along the way. The good news is that there could be some assistance already available.
A station rebuild usually includes all new equipment. Sometimes, it's not practical to replace everything, in which case, an incremental approach is needed. The Cumulus Indianapolis stations had a decent facility, but the on-air consoles weren't performing as expected or needed. The new consoles solved the existing problem, but they also set the stage for a future upgrade path.
Part 2 of the analog tape series investigates the electronics. We also offer some insight into the basics of electronic logic.
Within days after the FCC allowed AM HD Radio operation at night, Citadel Broadcasting Director of Corporate Engineering Martin Stabbert issued a memo to Citadel's AM IBOC stations to cease nighttime transmissions because of suspected interference issues. We talked to Stabbert about the memo and the interference problem to help set the record straight.
When the HD Radio time delay between the analog and digital signals is not set properly, the resulting effect can be an annoyance to the listener. Brian Beezley studied the station in Southern California and found some disappointing results.
Even the best technology will ultimately fail if no one wants to use it.
The time had come for KKDA Dallas to abandon the classic U-shaped cabinetry and start completely from scratch. The challenge was that the new studio had to be in the same location as the previous, which could not be enlarged.
There is no doubt that radio has been changing in dramatic ways in the past few years. But these advancements in technology and radio's overall capabilities haven't just changed the way we listen to music-it has changed the way we transmit music-and a radio engineer's job is more complex and developmental than ever.
The mechanics of analog tape and the value of VU meters.
There are many facets to broadcasting surround content. Besides choosing a technology, the station's technical staff has to become appropriately educated, suitable monitoring is needed to listen to the content, and the related infrastructure has to be suitably in place.
At this year's NAB Radio Show, Dolby Laboratories, Inc. will showcase real-world applications of Dolby Pro Logic II audio technology.

How to use a bench power supply, refurbishing an old laptop for EAS and fixing a module from a console you don't have.
Today, many of the clunky boxes that served us so well in the past have been replaced by networked hardware and software systems, which, while providing a far more powerful and compact platform to fill the operational needs of a facility, now take the form of black-boxes and software files. (The tools you use no longer came from a metal cabinet.)
CBS Radio's KYW Newsradio saw a move as an opportunity to update the facility, upgrade the infrastructure to a digital, router-based system and have an individual identity in the marketplace.
There are unique circumstances in every radio station--some physical, some due to specifically requested functionality--that cannot always be addressed by the features of the major components of the system. What becomes necessary in many cases such as these are special devices that fill in those gaps and provide the last little piece of the puzzle that makes the system complete.
A seven-station, medium market radio operation expands in a new facility.
