Here are some DIY FM Transmitter circuits that we have been published ... This FM transmitter circuit uses four radio frequency stages: a VHF oscillator built around transistor BF494 (T1), a ...

This sensitive FM radio ... circuit for hobbyists who want to build their own tuners instead of buying a “plug-n-play” finished product. The fm tuner circuit is designed with only 3 transistors. The ...

FM radio is ... the IF tuned circuits. The scope shows that at the center frequency, the signal passes through with no issue. However, as the frequency changes, the tuned circuit attenuates ...
