Marine Electronics

As email access is a big draw for many potential (and current owners) of single-sideband systems, we decided this was a good opportunity to see how our easy-install system performed in that area as well.Farallon Electronics, a Sausalito, Calif., company specializing in the design, sale, and distribution of gear for marine, commercial, and emergency service organizations, provided us with an SCS DR-7400 Dragon modem for testing.

Terry Sparks, author of the book A New Ham I Am, Made Simple For Cruisers, has seen plenty of HF radio installations-both SSB and HAM-and he noticed that even some expert installations fell short of those installed by pure amateurs. He offered this advice on how to avoid common pitfalls, whichever route you take:

Almost every sailor keeps some sort of logbook-from totally minimalist to absolutely exhaustive-and now, they have the option of keeping a digital logbook. We recently tested two digital logbook apps for the iPad: Logbook 2.5, from German company 2K Yachting, and WaveTrax from a British company of the same name.

Bear with us here. Before you get too far into this months report on single-sideband radios beginning, youll find it is incomplete. There are a lot of unanswered questions that we hope to address. Answers don't always come easy or fast in the work we do, but at the end of the day, we have to put out a magazine that reports our efforts.

To many sailors, single-sideband radio falls into the black arts category, those mysterious nautical skills (like anchoring or bleeding air from your diesel engine) that are discussed in hushed, reverent tones among bowed heads at most any dockside potluck or tiki bar where cruisers tend to congregate.

Both the marine radio and ham radio services use the same type of modulation, called single sideband. So when a fellow sailor says they have a single sideband on board, you need to ask, marine, ham, or both? At some point, any cruiser getting ready to make the jump into high-frequency radio communication will want to ask himself the same question.

Audio is transmitted via radio waves, with audio being impressed on a radio signal using a method called modulation. The two types of modulation that most everyone is familiar with is AM (amplitude modulation) and FM (frequency modulation). This is where the name of these broadcast bands are derived from.

These high-tech times present a whole new challenge for us cruising folks. How does one cope with the multitude of cords, chargers, headphones, and adaptors that accompany every new device that comes on board? Add two gadget-hungry teenagers, a few Kindles, several cameras, and you have cable mayhem. Reader Jessica Rice Johnson wrote us with her solution to the cord chaos aboard her familys 62-foot catamaran.

After the roller-furling jib, the most valued piece of gear aboard for many sailors is the autopilot. So fond of autopilots are skippers and first mates, many even name their units-Otto the autopilot, Joshua (after infamous sailor Joshua Slocum), Amelia (after historic female pilot Amelia Earhart), and WTF are a few that weve met during our cruises.

Whether youre contending with the violence of an abroholos or the gentle puff of a zephyr, it helps to have an idea of wind intensity. For the last several months, testers have been closely examining the tools sailors use to measure and display wind information. This article wraps up our review of mechanical vane sensors and displays, focusing specifically on choosing the best combination to meet your needs. Future reports will look at ultrasonic wind sensors, which have no moving parts, and a build-it-yourself wind sensor that uses an Arduino open-source electronics platform.
