Build an am transmitter circuit by using my oscillator design?


Can you help me make an AM transmitter with this oscillator circuit I have? I want to transmit a signal with a 550Khz carrier signal, but I dont know how to make a matching transmitter circuit with this oscillator.

    There's so much wrong with that circuit, I don't know where to start.

    Your circuit was totally wrong !   How could having  RF output through +6V power terminal and the so call output was grounded ???   

    To make a 550Kc transmitter is very simple, provided build a 550Kc oscillator ( or clock ) first, available simple to build with 555 IC. Then let its output amplifies one more stage to obtain big enough RF current to drive a final RF power stage, in class D is simple and efficient.

    how could I possibly build anything over the internet?

    and I don't think that will oscillate. 


    drop that circuit, and search the internet for an AM transmitter circuit. there are many available. Note that the FCC limits power.
