G'day, having trouble looking for the same beast, will let you know if I have any joy down this end of the world, any joy your end? Subs should do fine by the way.

I have a question , can a crystal radio send signals and receive without using electrical power? I built one as a kid that could receive but can they send without electrical power? I thought I read that you can put a rod in the earth to get power to send with , or am I wrong? If they can send what are distances ? Thanks please reply to rti94@aol.com
