G'day all, just installed the newly arrived CB200 AIS transponder. Arrived at 2 PM and was up and transmitting at 3 PM. Not a bad "out of box experience" for a change. Its sensitivity is at least as good as the SR161/2 units as I've logged one ship at 47.42 nm already which is the best that I'd ever gotten on the SR161/2. We are using the same antenna and cables and connectors just so we all know that our installation is clean ;-) Confirmed our signal with several nearby ships already. First time any of them have received a class B AIS signal! We need to work on the way it can transmit distress signals i.e. Mayday with your name, call sign and position. Seems there is a lot more hidden in the lousy manual about what it actually might be able to do both as a nav tool and also as a safety device. We have also seen a few more of the AIS signals transmitted from land locations. We'll see if there are even more on our trip back down to Venezuela as they are helpful "beacons" with a high degree of accuracy as to their location. It is interesting as once set up it just sits here xmitting our information for others to use or not as they see fit. No user interaction (or distraction) is required. I expect you'll be able to get them with FCC approval sooooooooon. This one is EC/EU stamped and was under $1200 landed with freight and duty with an active GPS antenna. As always YMMV........
