The 2007 NAB Radio show heads to Charlotte
The Queen City is home to this year's NAB Radio show. Charlotte, NC, was also nicknamed The Hornet's Nest after General Cornwallis' description during the Revolutionary War. The show, no doubt, will do that name proud as it brings together a dizzying hub of new products and sessions set on improvement.
The show, running from Sept. 26-28, at the Charlotte Convention Center, will feature products from more than 100 exhibitors. Some may be familiar, some are brand new. Either way, this issue of Radio magazine guarantees to be an amazing resource. From audio software to codecs, tuners to transmitters, soundcards to databases, antennas, processors, and so much more, you will not be bored on the exhibit room floor. We have included here a plethora of products from some of the 2007 show's exhibitors.
Sessions this year are focused on reigniting radio. In this year's SBE Radio Engineering Forum, you will hear about topics such as VSWR measurements, of course HD Radio, and have the opportunity to be certified as a digital radio broadcast specialist. And there are plenty more sessions to attend, with topics including the infinite dial, podcasting and the future of radio. For a session overview, turn to page 54.
Perhaps best of all, the NAB Radio Show is a great place to meet new people and reconnect with old friends. The show is offering a variety of meet and greet sessions, most of which include food, which can never be a bad thing.
So get to the show early and stay late because this year promises to be a mecca of new products, education and networking.
