some persons asked simple radio circuit diagrams.Here you can see very simple circuit diagram.When I tested this my first time I enjoyed very much.When the signals are coming you can here some sounds like ne ne nee nic nee nee nee nee.so test this and enjoy. Note: # Don't use more than 4.5V # Build this on a pcb #If the signals don't come move the main coil here and there then you can here some sounds. # Firstly this circuit was designed by Elmer G. Osterhoudt in the early 30's
