Convention time
All attention turns to the NAB Show this time of year. It is the biggest industry event of the year after all. Even if you don't go or have never gone, it still has some relevance, since this is where the latest product developments and technology introductions specific to broadcasting are unveiled.
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.
LPFM rules and proposals released
The news is generally good if you are an LPFM licensee, but bad for FM licensees who plan to make facilities changes that threaten displacement of an existing LPFM station.
New Products
New products from Sony, Arco, K-Sun, Henry Engineering, RF Signs, Allen and Heath, Yellowtec, Tapco, Panamax, Schmart Board, Audio Science, Rapcohorizon, Harrison by GLW, MXL Microphones, Liquid Compass, Audix, Wirecad, Blue Sky International and Netia.
Adobe Audition 3.0
Obviously, Audition 3 is far from lacking when it comes to creating top-quality audio. Whether a musician, voice-over artist or radio producer, Audition 3 is pushing the envelope by expanding creative possibilities, making affordable features efficient and available.
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.
Denon DN-C640
The Denon DN-C640 is a true professional CD player and the network functionality adds to the experience. The response on playback is tremendous. It took less than a half-hour to have the unit up and running on the network and most configurations were done without using the manual. Intuitive design and user functionality make this CD player a useful tool in any broadcast facility.

Problems and solutions
In the eyes of broadcasters, December was a busy month for the FCC. Broadcasting is just one small part of the FCC’s concerns, so when several significant rulings are made at once, broadcasters naturally take notice. Two recent actions deal with broadcast ownership while another deals with programming localism. Now that the FCC has acted, there are more questions raised than answers provided.
