Low-power FM

In The Forgetting Curve, the MemeCast is an underground radio show broadcast by a low-power FM transmitter.  Today’s commercial FM radio stations transmit their programming over thousands of watts of power. This requires big money (and a big transmitter) and can reach hundreds of miles (without interference). Low power FM stations (LPFM) are broadcast at around 100 watts of power, which means they can only cover 10-15 miles. You can build one yourself, and yes you can fit one in a lunch box. (See below.)

We actually have hundreds of low power stations across the country. Most, if not all, are community-based or individually run stations.  (That is, they are not corporate controlled stations.)  They talk about interests specific to a community, play music, etc.  These LPFM’s can play a really important part in the community.

For instance, after Hurricane Katrina hit New Orleans in 2005, the area’s communications–radio, tv, phones, internet–were almost eradicated. A few hackers set up a LPFM (among other things) called Algiers Radio 94.5 to serve the community. The photo below is from Jacob Applebaum’s Post-Katrina blog.

“…the themes of inquiry and fighting back will resonate
with young and old.”

“The novel is taut and lean; Smibert’s prose is quick and fluid…”
–Horn Book Magazine

“Engaging, spirited characters and a plot that can stand on its own…This story could provide great fodder for discussions about the relative roles of government, business and the individual in a world of increasing consolidation and conformity.”
