Transmitting Transmitting on m is a bit more complicated. Amateurs do successfully communicate by bouncing their signals off the surface of the moon, called Earth-Moon-Earth EME transmission.

On the second screen shot you can see what John's signal looked like before my local QRN started. Photo Gallery This map shows th If you have a conductor that allows electrons your signal to flow but has some resistance to it the wire alloy , that lowers the velocity of the wire and is part the reason why a thicker conductor usually is better, but not always practical for long wire lengths. The amateur 40m band is 7. Its all in the math and materials.

Maximum current 5 Amps. Since the United States is different than the "metric" world, here is the conversions for the "theoretical" math above for antenna lengths.
