    use a 9v battery, take +ve to relay "switchingcoil1 in" .

    "switchingcoil1out" to "NaturallyOn pin" (make this a 5-10 turn loop wire away frm circuit)

    "RELAYOUTground pin" to battery ground

    put a capacitor across it to adjust frequency(i forget where exactly!!)

    .........actually thats still RLC, you cant not have it, since you need L to make fields, and R and C just kinda happen (even without capacitors in it), wires can act as Capacitors & inductors

    If you just want to produce radio wave then just make a coli and flow electricity through it.

    It will also produce some Electromagnetic Wave. While you switch on or off the coil.

    But If you want to produce controlled and high power Radio wave then you should use RLC.

    The sky is full of radio waves from sources other than LC circuits: lightning, Jupiter, The big bang, neutron stars, the sun, my central heating thermostat etc etc.
