Wow, all of a sudden there's a flurry of cool things coming my way.
As the guy from Sydney Wireless said when he posted this, "Holy crap -
how Macgyver is that." :-)

Brazilian satellite hackers use high-performance antennas and homebrew
gear to turn U.S. Navy satellites into their personal CB radios.
CAMPINAS, Brazil ? On the night of March 8, cruising 22,000 miles
above the Earth, U.S. Navy communications satellite FLTSAT-8 suddenly
erupted with illicit activity. Jubilant voices and anthems crowded the
channel on a junkyard's worth of homemade gear from across vast and
silent stretches of the Amazon: Ronaldo, a Brazilian soccer idol, had
just scored his first goal with the Corinthians.
It was a party that won't soon be forgotten. Ten days later, Brazilian
Federal Police swooped in on 39 suspects in six states in the largest
crackdown to date on a growing problem here: illegal hijacking of U.S.
military satellite transponders.
"This had been happening for more than five years," says Celso Campos,
of the Brazilian Federal Police. "Since the communication channel was
open, not encrypted, lots of people used it to talk to each other."
The practice is so entrenched, and the knowledge and tools so widely
available, few believe the campaign to stamp it out will be quick or
easy.
Much of this country's geography is remote, and beyond the reach of
cellphone coverage, making American satellites an ideal, if illegal,
communications option. The problem goes back more than a decade, to
the mid-1990s, when Brazilian radio technicians discovered they could
jump on the UHF frequencies dedicated to satellites in the Navy's
Fleet Satellite Communication system, or FLTSATCOM. They've been at it
ever since.
Truck drivers love the birds because they provide better range and
sound than ham radios. Rogue loggers in the Amazon use the satellites
to transmit coded warnings when authorities threaten to close in. Drug
dealers and organized criminal factions use them to coordinate
operations.
Today, the satellites, which pirates called "Bolinha" or "little
ball," are a national phenomenon.
"It's impossible not to find equipment like this when we catch an
organized crime gang," says a police officer involved in last month's
action.
The crackdown, called "Operation Satellite," was Brazil's first large-
scale enforcement against the problem. Police followed coordinates
provided by the U.S. Department of Defense and confirmed by Anatel,
Brazil's FCC. Among those charged were university professors,
electricians, truckers and farmers, the police say. The suspects face
up to four years and jail, but are more likely to be fined if convicted.
First lofted into orbit in the 1970s, the FLTSATCOM bird was at the
time a major advance in military communications. Their 23 channels
were used by every branch of the U.S. armed forces and the White House
for encrypted data and voice, typically from portable ground units
that could be quickly unpacked and put to use on the battlefield.
As the original FLTSAT constellation of four satellites fell out of
service, the Navy launched a more advanced UFO satellite (for Ultra
High Frequency Follow-On) to replace them. Today, there are two FLTSAT
and eight UFO birds in geosynchronous orbit. Navy contractors are
working on a next-generation system called Mobile User Objective
System beginning in September 2009.
Until then, the military is still using aging FLTSAT and UFO
satellites ? and so are a lot of Brazilians. While the technology on
the transponders still dates from the 1970s, radio sets back on Earth
have only improved and plummeted in cost ? opening a cheap, efficient
and illegal backdoor.
To use the satellite, pirates typically take an ordinary ham radio
transmitter, which operates in the 144- to 148-MHZ range, and add a
frequency doubler cobbled from coils and a varactor diode. That lets
the radio stretch into the lower end of FLTSATCOM's 292- to 317-MHz
uplink range. All the gear can be bought near any truck stop for less
than $500. Ads on specialized websites offer to perform the conversion
for less than $100. Taught the ropes, even rough electricians can make
Bolinha-ware.
"I saw it more than once in truck repair shops," says amateur radio
operator Adinei Brochi (PY2ADN) "Nearly illiterate men rigged a radio
in less than one minute, rolling wire on a coil."
Brochi, who assembled his first radio set from spare parts at 12, has
beentracking the Brazilian satellite hacking problem (.pdf) for years.
Brochi says the Pentagon's concerns are obvious.
"If a soldier is shot in an ambush, the first thing he will think of
doing will be to send a help request over the radio," observes Brochi.
"What if he's trying to call for help and two truckers are discussing
soccer? In an emergency, that soldier won't be able to remember
quickly how to change the radio programming to look for a frequency
that's not saturated."
When real criminals use these frequencies, it's easy to tell they're
hiding something, but it's nearly impossible to know what it is. In
one intercepted conversation posted to YouTube, a man alerts a friend
that he should watch out, because things are getting "crispy" and
"strong winds" are on their way.
Sometimes loggers refer to the approach of authorities by saying,
"Santa Claus is coming," says Brochi.
When the user's location is stable, the signal can be triangulated.
That's how the Defense Department got the coordinates to feed
Brazilian authorities in March's raids.
While Brazil may be the world capital of FLTSATCOM hijacking, there
have been cases in other countries ? even in the United States. In
February of last year, FCC investigators used a mobile direction-
finding vehicle to trace rogue transmissions to a Brazilian immigrant
in New Jersey. When the investigators inspected his radio gear, they
found a transceiver programmed to a FLTSAT frequency, connected to an
antenna in the back of his house. Joaquim Barbosa was hit with a
$20,000 fine.
A technician with Anatel, speaking on condition of anonymity, says the
chief problem with ending the satellite abuse in this country is that
U.S. and Brazilian authorities simply waited too long to start.
Thousands of users are believed to have the know-how to use the
system. After a bust, the airwaves always go quiet for a while, but
the hijackers always return.
One week after the "Operation Satellite," Brochi met with Wired.com at
a gathering of amateur radio enthusiasts in a bucolic square in
Campinas, about 60 miles north of Sao Paulo. Brochi switches on his
UHF receiver and scans through the satellite frequencies.
It's relatively quiet now on the satellite underground, except for the
static-like sound of encrypted military traffic. But eventually, a
lone creaky voice cuts through. It's a man in Porto Velho, the capital
of Rond?nia, a day's drive north into the upper Amazon basin. He's
making small talk with a friend in Portuguese. The satellite pirates
are creeping back on the air.
