Background:
Tired of listening to Led Zepplin or NPR on your I-Pod? Wouldn't you
like to be able to carry with you the kinds of ham radio conversations

Mike, KL7R, in Juneau, Alaska, and Bill, M0HBR, in London, England
meet regularly on the ECHOLINK system to discuss their homebrew radio
projects. We are making them available as PODCASTS.
