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.

Kowa PX-10
Some devices have a front panel that demands attention. Such is the Kowa PX-10 flash memory audio player. This box simply belongs in the studio; but is the PX-10 more than just eye candy for the control room?
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.
