On the airwaves... for a dollar or two
http://www.tacticaltech.org/node/225
Hello, hello! Low-powered radio is one of the few technologies even the
poor can afford. It's also about the easiest medium to create content for.
In the midst of all the FLOSS talk, there was space at Asia Source for
some other (non-software) relevant technology or two.
These points were made by Dr Arun Metha today, when he showed Asia Source
participants how it was possible to build a simple FM transmitter with
inexpensive components.
"Speech is natural. It is efficient. It's five times faster than typing,
and ten times faster than writing. It's flexible. We don't have to touch
or see anything to create speech. For people like the blind whom I work
with this is the only option," he said, paraphrasing the words of Victor
Zae.
Dr Metha, an electrical engineer and computer scientist who has studied in
India's prestigious IIT (Indian Institute of Technology) network, has been
one India's early telecom- and cyber-activists.
He whipped out the tiny radio transmitter that he had hacked together.
"(To be effective) we need to be able to make a radio station anywhere
where a radio or TV is being repaired with easily available parts. This is
not rocket science," he said, as his demo took by surprise those attending
his talk.
Audio, he pointed out, is far more democratic than other media. You don't
need to be terribly well educated to make your point. "Trade unions and
women in bazaars can also make their voices heard," he said.
Metha's low-powered transmitter has a broadcast range of just
half-kilometre. He also discussed the possible relationship between the
Internet and radio.
He pointed out that the Indian laws allow for 50 milliwatts cordless
microphones to be used, but not for low-powered radio transmitters of the
same strength. "If the President of India can use this technology, why
can't poor women in a village do the same thing (to share useful
information)?" he questions.
Patrice Riemens narrated experiences from Europe, with radio. Other
participants from Indonesia mentioned how they had set up one during the
recent tsunami disaster.
Says Metha: "My current passions include village radio and software for
the handicapped." He has written the eLocuter software, to meet the
communication needs of the noted scientist Professor Stephen Hawkings. See

Metha's websites are at http://www.indataportal.com,
http://www.holistic.com and http://www.radiophony.com -- the last contains
plans for building a low-cost radio transmitter.
