(No-Host Lunch!).
The Portland meetings are on the second Tuesday of every month. Everyone is welcome to attend the meetings.

Audio over IP is the future for many industries, and broadcast is leading the way. Mike Uhl from Telos-Omnia-Axia and Buck Waters from BGS introduced some of the latest products that include Livewiretm technology, including the Omnia One audio processor and the Zephyr IP audio codec. A demonstration of the Axia control surface was also available. See how a Cisco switch can become the backbone for an audio network using common Ethernet standards. http://www.axiaaudio.com and http://www.bgsfl.com
Kevin Campbell of APT will discuss IP Audio for broadcast STL and buy lunch. See http://www.aptx.com/content.asp?page=1&site=1 .

Dylan James, a former Entercom-Portland Remote Engineer, was on the air at 2 AM on Tuesday morning December 4th at KITI-FM in Centralia (http://www.live95.com/) when he noticed water creeping up the parking lot in front of the station. After it rose 18 inches within 15 minutes he knew something was very wrong. He woke up their AM station's morning man and they got as much stuff off the floor as they could. This was a good thing because by 3 AM the water was up to the outlets and they turned off the station's studio and office power, taking the stations off the air, and took refuge in an insurance company office on the second floor of the building.
The water receded enough later that morning for staffers to get most of the water out of the building and go back on the air about noon.
Dylan thinks that water in the KELA/KMNT studios down the street was even deeper.
