    I also carry a PLB on my person, but they aren't a replacement for an EPIRB because they aren't required to be buoyant (in fact many that do float only float upside down turning the antenna into a...

    Delorme complexity

    I think the right choice is to stick with the YB versus the DL.

    For what it's worth, I have had a DL InReach velcroed to a bulkhead inside my cabin and it has been sending automatic position reports for the last 4 months every 4 hours when the boat isn't...
  6. Suppressing RFI from SSB for Raymarine autopilots

    I have had the same problem many others have had with my Raymarine autopilot: transmit at high power (100 watts) on the HF band (SSB), and the autopilot reboots, locks up, or just goes goofey.

    Thanks Mark. That sounds much more elegant than using a bent nail in an electric drill to remove the coring. But I still feel that I'd experience less emotional trauma from drilling holes in my own...

    For those who want tracking, the Delorme products cost about $300, use the same Iridium satellite constellation as the Yellowbrick, and have the ability to send and receive text messages. You can...

    I agree that allowing the entire planet to track a vessel's progress is a little creepy, though ever since the invention of radiotelegraph long distance racers have been reporting in with their...

    The short answer is "no, tracking vessels with Class B AIS via satellite is not yet reliable or feasible". AIS was intended for line-of-sight propagation within a short range ad hoc time-sharing...

    Actually, your transmitter range is quite good. I usually lose Class B stations north of Pacifica when they are close in ashore. The hill at the HMB airport intervenes to block reception. Your range...
