Simple radio circit diagram



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

    This is a bit confusing. Can u help me?
    Where would the + and - terminals from the power source be connected?
    How many turns should be on the coil?
    Is the coil tapped in the middle as the diagram suggests? thanks

    1) Yes this is taped at the middle( after turning 1/3 )

    2) According to the Gage that you use and according to the turns that you turn the frequencies are changed.L1: about 30-35 feet of 22-gauge enamel wire.

    3)This circuit doesn't need battery power it runs with the power of radio waves
