K7NS builds a very simple 80 meter cw qrp transmitter made out of a homemade zinc negative resistance diode. This simple radio transmitter is made without using any vacuum tubes or transistors, and can be heard several miles away.

Thanks to W9RAN for his contribution of using a quarts crystal in place of an LC circuit.
