Standard Horizon: Months before we left to go cruising, we bought direct from Standard Horizon their Matrix AIS-enabled VHF radio at the Annapolis boat show. It stayed packed away in the box for another year or so, when we finally installed it. It worked great. Then, in 2012, we bought the RAM3 remote mic for our cockpit. It worked great—until it didn't. This past summer, the remote started to fail, acting weird. I talked to Standard Horizon and they said the problem was likely in our main radio, a non-owner-serviceable fuse. They'd seen this before. Then, before I could send it in (we're in Mexico), the symptoms changed completely—the remote went dead as a doornail, and this despite my being able to measure voltage at the socket it plugs into. The house radio continued to work fine. At great expense and inconvenience, I decided to take a chance and send only the remote, so that we wouldn't lose our house radio. Bingo, they got the remote, confirmed it was dead, fixed it at no charge, bench tested it, and sent it back. When I got it back, it was still completely inoperable.
