    Nice job Ben. Good article about a reasonably priced AIS receiver!

    Neat package, Ben. I like that the built-in multiplexer can take a 4,800 baud input and combine it with the AIS/GPS output data stream at 38,400, that’s a nice feature.
    But I’m not sure about the portability scenario – seems like you’d need a GPS antenna (fairly easy) and either a dedicated AIS antenna or splitter (not so easy) as part of the package. The shortest AIS antennas I’ve seen are 36″ and not really designed to be portable…

  3. Interesting, Ben. I note that the specs call for -105 dbm sensitivity, which is well over a microvolt (at 50 ohms) – most marine VHFs I’ve measured were closer to -115 to -118 dBm for reasonable receive quality, so this receiver is indeed less sensitive than most. Perhaps they do this to give it protection from nearby transmitters?
    You could use it with an antenna intended for use with a handheld radio (some even have a BNC connector standard!) though performance will be limited (good inside the harbor or around the bay, perhaps).
