The Muscatine County emergency management director doubts it will ever happen. But if the county’s digital communication systems were to fail during a catastrophe, a local group of amateur radio enthusiasts say they have the backup plan. A team of 20 engineers, hobbyists and old-school radio gear-heads has formed the Muscatine County Amateur Radio Emergency Service, as part of the Muscatine Amateur Radio Club. They’ve been working since last June to refurbish a trailer suited with emergency service radio equipment. It is one of 10 trailers brought to Iowa around 11 years ago by a Homeland Security grant, according to local member Scott Richardson.
