Any of you HAM types ever make anything like this: http://www.auroralchorus.com/bbb4rx3.htm ? Turns out, you can actually hear aurora borealis on the cheap with one of Steve McGreevy’s WR3 radios http://www.auroralchorus.com/wr3.htm, which is a minor upgrade to the first link. I had always assumed the required radio hardware would be very pricey.
I’ve got an email in to him asking permission to make this into a kit. Would be great if I could find a radio geek to help with the hardcore electromagnetic stuff. My eyes glazed over trying to grok all the technical details he provides.
Have a listen to one of the Whistler recordings http://www.archive.org/details/auroral_chorus_2_cd . Very cool stuff. We’re coming up on the peak of 11 yr sunspot cycle next year, so this will be fun and educational toy to have.
