When a shower such as the Perseids is under way, transmissions from hundreds of miles away can ricochet off these meteor trails, and be heard much farther away than usual. Tune an FM radio to the exact frequency of a station on a distant island. Depending upon where you live, you might try KQNG at 93.5 MHz on Kauai, or KOAI at 95.1 MHz on Maui, or KPOI at 97.5 MHz on Oahu. Be sure you pick a station that you can't hear. That's right, one you can't usually hear.
Lower frequencies work best.
Turn up the volume a bit, and wait for the Perseids to hit their peak, after midnight on August 12. You'll hear brief spurts of music or commercials if you wait a bit. You'll hear these distant stations clearly for a few seconds while the meteor trails act as reflectors, and then fade out quickly as the atmosphere returns to normal. So, it's a month of cycles. I'm cycled back into the writer's chair.
