Yeah, thinking about a 17hz RF transmitter makes my head hurt. We do have a pretty serious 60hz transmitter, though, that even has sufficiently long antennas...
Of course -- the desired 17Hz must be the frequency of whale songs! Good thing they're not extinct yet! (Hey, wasn't there a Star Trek movie about this?)
You can hear the 60 hz buzz near high power lines, but without piezo stuff I don't think you can swap EM for sound. -- Mike Stay metaweta@gmail.com http://math.ucr.edu/~mike
