One of my favourite finds during our recent inventory of
Spray was the Sony 7600 single sideband radio receiver. When I was a kid, my sister and I became
amateur “ham” radio operators (Kentucky hams, we used to call ourselves). We spent many happy evenings eavesdropping on
conversations, news and music from around the world, dreaming of the travels
and adventures we would have.

Despite the many miraculous technological advances of
the past 30 years, shortwave radio is still the best way for global cruisers to
have news and information from just about anywhere on the planet. Some AM/FM radio stations can be picked up along
the coast for 50-75 miles. Beyond that,
if you want to stay in touch with what’s going on in the world, you have to
rely on signals bounced off the ionosphere, which is shortwave or World Band
Radio. During a brief stroll along the
dial (“dial” is what older folks call the seek tuning button) you can stumble
onto a mix of traditional music from Southeast Asia, a documentary about maple
syrup harvesting from Canada, and dire warnings from doomsday cults
broadcasting from….well, they never really say.
You may be asking yourself how useful (or indeed,
desirable) it would be to have the ability to listen to, say, classic Chinese opera while at sea. But you would be ignoring the fact that a SSB
radio not only captures radio broadcasts, it also provides access to
all-important weather and navigation information at sea beyond the reach of the
marine VHF radio. Combined with a
computer and a good antenna, you can obtain both text and graphic weather data
anywhere in the world. Add a
transmitter, and you are wired to participate in the global village.
There are many radio nets established especially for
cruisers by amateur radio operators around the major cruising destinations of
the world (or more specifically, major cruising destinations of the world where
old hams go to retire, which is to say, predominantly in areas with warm
turquoise waters, palm trees, plastic flip-flops, and little fruity drinks with
umbrellas … hmmmm, I wonder if I have to be 65 to join them ?). These nets provide local sailing and port
information, reports of piracy, queries from worried families about late
arrivals, general gossip, and message relays.
They broadcast at a fixed time every day, providing a great source of
entertainment, a bit like Garrison Keillor’s “Lake Woebegone Days” on the high
seas.
What breaks my heart is that SSB is now most often labelled
as “not dead yet”. The satellite phone
and the ability to connect to the internet from anywhere on the globe is
rapidly undermining radio services. On
31 December 2011, Radio France International announced that it would no longer broadcast
offshore weather reports on short wave, depriving French sailors of one of their
only sources of offshore weather news from a human voice. An informal poll on Sail the World suggested,
however, that the howl of protest was mostly an elderly one, with younger
sailors greeting the news of the terminated broadcast with “so what?”
While it is tempting at this juncture to dive into the
sociological ramifications of this finding, I think I would prefer to avoid the
debate altogether and just install both a SSB system and a satellite phone on
Spray. But I sure hope those radio net
communities are still around when I’m ready to settle down and plant my toes in
the warm sand somewhere. And a final
word to the younger generation of sailors who remain stubbornly insensible to
the human connection: when the robots
rise up to enslave and kill us all*, the only place that will be safe is on a
boat surrounded by salt water, and you can be sure that all us survivors will
be coordinating our efforts via good old shortwave radio.
(* for a survival guide, see Daniel Wilson’s “How toSurvive a Robot Uprising: Tips for Defending Yourself Against the Coming Rebellion.”)
Addendum: After
being mercilessly teased by my former colleagues for my naïveté regarding a
robot’s ability to operate in salt water, I humbly admit that this was an inexcusable
oversight on my part. After having
worked for more than 10 years coordinating bits of the Global Ocean Observing System,
I should have immediately thought of the Argo and Glider programmes, which are
based on autonomous or remotely-operated floats. In my own defence, to call them robots at
this point is a BIT of an exaggeration.
Nevertheless, I did take this opportunity to remind my friends working
on Argo that it is not too early to be thinking about a global “kill switch”
for those little buggers.
