I just traced out the board.
A generalized schematic diagram of a medium wave transmitter which covers a standard broadcast band 530 1700khz converted from a 4 or 5 valve superheterodyne radio is shown in fig.
I replaced these with 3 pin 1 amp 8v regulators and run the board at 12vdc to give headroom for regulation.
They provide no schematics.

This is circuit of 5km long range fm radio transmitter circuit.
A fm transmitter can cover maximum distance here showing a long range fm transmitter circuit diagram that can cover the distance upto 5 km and with the power of 1 w.
Spitfire pll medium wave and 160m amateur band am transmitter 9khz channel spacing.
During daytime only local stations can be received.
In wireless communication the frequency modulation fm carries the data or information by changing the frequency of the carrier wave as per the information or a message signal.
The fm transmitter achieves the application of very high frequency vhf radio frequencies.
There are two 50 ohm resistors that split the 9v power between the rf and af sections of the board dropping the voltage to about 8vdc.
Community radio stations and vintage radio collectors around the world use the spitfire am transmitter generally accepted as having one of the best frequency synthesizers and modulators of any part 15 compliant am transmitter available.
This circuit is designed with limited power output to match the fcc regulations and still produces enough amplitude modulation of voice in the medium wave band to satisfy your personal needs.
Propagation in the night allows strong signals within a range of about 2000 km.
What is fm transmitter circuit.
Converts the amplified signal to radio waves.
