How to pick the perfect VHF antenna for your boat, and your price point. >As any boat owner knows, there is a wealth of options when choosing a new VHF antenna.
Class B AIS Transceiver
Icom’s MA-500TR—the company’s first (and only) Class B AIS transceiver—broadcasts position, track, and speed data derived from its own internal GPS. Cosmetically compatible with Icom’s rugged, chunky IC-M504 and IC-M604 radios, the MA-500TR monitors the two AIS frequencies for incoming information
Vesper Marine is a New Zealand-based company that specializes in easy-to-use AIS equipment for recreational and light commercial craft.
Recently granted FCC approval, the third member of Vesper’s Watchmate range is the Watchmate 850, which has a built-in AIS B transponder and is priced at $1,099. While the transponder broadcasts details of your boat’s

Spot can send, but it can’t receive. The Globalstar constellation on which it depends has a long-standing problem handling two-way data. Solution?
Spot is a pint-size tracker
Globalstar has introduced a second generation of its Spot satellite tracking-and-messaging device. About the size of a pack of cigarettes, the new Spot Messenger is smaller than the
Inmarsat, the granddaddy of satellite communication services, has launched a truly portable satellite phone.
The company says that the new phone is "targeted primarily at professional users in the government, media, aid, oil and gas, mining and construction sectors," but its $699 list price and pay-as-you-go airtime at about $1 per minute are likely to win it
There are more than 150,000 apps for the iPhone, ranging from the puerile and pointless (such as iBeer, that turns your $300 phone into a virtual beer glass) to the almost indispensable (Google Earth, a guitar tuner, and a virtual spirit
Wireless On The Water?
We have wireless networks in our homes and offices. Why not on our boats, too?
I can’t remember the last time I used a phone that had a wire attaching its handset to its base, but the fact that I have a hard-wired computer network at home apparently qualifies me as one of the last of the dinosaurs. And given the
Twenty-first-century technology has changed the way your electronics communicate.
It’s more than ten years now, since we learned to spell “millennium,” stocked up on canned food, and braced ourselves for the computerized apocalypse that was supposed to happen as we rolled over into the 21st Cen-tury—but never did. Yet while Y2K never lived up to its
One of the drawbacks of forward-looking sonar has always been that sound travels much more slowly through water than radar waves travel through air. At a sluggish 5,000 feet per second, it takes half a second for a sonar “ping” to travel out and back to an object a quarter of a mile away. So for a scanning sonar to build up even a crude picture of what's ahead can easily take several seconds.
KVH has joined the growing list of suppliers that are offering phone and Internet services through Inmarsat's new Fleet Broadband 150. With a dome that is just 13.5" in diameter and that weighs a little over 11 pounds, the Tracphone FB150 is the smallest and lightest of KVH's family of Inmarsat satellite broadband systems.
Described by the company as
After conducting extensive beta-testing that included sending five terminals around the world in boats competing in the Vendee Globe single-handed sailboat race, Iridium has launched the world’s only global broadband service.
Called OpenPort, the new service provides three independent phone lines and an Internet connection at anything up to 128 kilobytes
The latest addition to Icom’s lineup of handheld VHFs is the IC-M36, a waterproof, floating radio with a couple of extra features specifically intended to minimize the effect of background noise. One is a noise-cancellation system similar to those found on headphones from Sony and Bose. A second microphone on the back of the radio picks up background noise, which
Long known for its navigational electronics, Garmin is now about to enter the VHF market with two fixed-mount radios. Pre-release information describes the VHF100 as an entry-level radio, but at $250, it’s definitely full-featured. It’s waterproof, has a large 3.2-inch screen and straightforward controls, and can handle NOAA weather alerts as well as the usual
Everyone understands the importance of a VHF radio. A fixed-mount unit provides a key communications link to other boaters, the Coast Guard, and local police. If you travel offshore, a VHF may be your only means of requesting assistance. On the other hand, if disaster strikes or your boat loses power, a portable handheld VHF could make the difference between inconvenience and calamity.
Q: I’m installing a new AIS transceiver, and it has a built-in antenna splitter. How can I attach my AIS receiver, VHF radio, and FM stereo to the antenna?
A: Built-in antenna signal splitters invariably introduce some signal loss. So far, most manufacturers don’t specify how much, but one I talked with suggests that it’s “about 2 dB,” and that’s a lot. So since your VHF is your
It’s long past time that the magnetron was consigned to the dust bin of maritime history,” enthused Larry Brandt, a commenter on my electronics blog who is both a professional mariner and a radar tech with experience working on everything from 60-ton 1960’s Air Force sky scanners to the super-compact, super-high-performance solid-state sets
Is Icom a Johnny come lately for introducing the MXA-5000 AIS receiver just as Class B transceivers finally hit the market? I don't think so. Not every skipper is as keen to be seen via AIS as I am, and if said skipper does want to monitor Class A and B AIS targets, ICOM's offering looks easy to
