Northrop Grumman and ISS during late 2007 and early 2008 produced and installed some of the largest ALERT AM systems to date in 3 counties surrounding Richmond, Virginia. Chesterfield and Hanover Counties, each with 7 stations, use Wireless Audio Links to distribute audio. Goochland County uses a sideband signal generator at 7 locations. All 3 counties use Workstation Audio Control PCs to produce/send broadcasts. Customers say they are pleased with how “smooth and clean” the installations went. The real proof? Already the systems have been used to broadcast notices of brush fires, a 911 outage and ice storms that caused power outages. And the Counties are ordering more ISS products.
