AM Micro Transmitter (CB1526E )

    This circuit is from an 1977 American publication. The coil consists of 30 + 70 turns of 28 AWG wire on a ferrite rod. The transistors can be the BD135 and the transformer is an output type for transistor radios. The amplifier can be changed to more modern types, with change of the circuit like, for example, the LM386.
