Powerful AM Transmitter

This is the circuit diagram of powerful AM transmitter which use ceramic resonator/filter of 3.587 MHz. Resonators/filters of other frequencies such as 5.5 MHz, 7 MHz and 10.7 MHz may also be used. Use of different frequency filters/resonators will involve corresponding variation in the value of inductor used in the tank circuit of oscillator connected at the collector of transistor T1.
