The transistor Colpitts oscillator oscillates at a frequency in the FM broadcast band. It is tuned with the trimmer capacitor.
The audio input causes the transistor to conduct more and conduct less which changes its capacitance which changes its frequency producing AM plus FM. FM radios ignor the AM.
