What's you typical day at the NAB Show? Everyone's agenda is different during the convention. I am often asked what my day is like at the convention
As a stand-alone medium, traditional broadcasting is subject to a multitude of restrictions as compared with other Internet-driven delivery platforms
We chose the Sony PCM-D50, which is capable of recording WAV files and MP3 playback. The device itself has two built-in microphones; an external handheld microphone can also be used, and there are connections to attach a line-level device
With the Remote Mix 4, JK Audio has introduced 21st century cell phone and Bluetooth technology to the remote broadcast clique. In this age of wireless-ness, it’s a timely introduction
Several years ago, a new technology called Web services began to make headway in software architecture. The technology leverages the same mechanisms used by Web browsers and Web servers to allow systems to more easily communicate and share data. Web services have proven extremely useful and are now considered to be mainstream software architecture

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?
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.
Day Sequerra has updated its M2.0 HD modulation monitor, adding some nice and very useful features. I first reviewed the original M2.0 in Radio magazine in May 2006, and the new M2.2R model is an attractive piece of test equipment that will likely go in your facility where it can be seen by you and others.

A Texas AM station was fined $8,800 for failing to maintain a main studio and power down at sunset. An FCC inspector, after checking on four successive days, could not find the station's main studio. While conducting this search the agent took signal measurements and determined that the station was not powering down at night as its license required.
One reader writes, "I don't know how far HD Radio-equipped stations blanket analog AM stations but I can provide you with a very educated guess that the actual receiver has a lot to do with rejecting that interference or permitting it."

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.
