Am having issues with my Fm tx, the difficulty lies in the amplification stage(s) but i must resolve it. Experts are welcomed and genius are most welcomed. Ready to learn...
Have you seen my FM transmitter circuit? When it is built on a pcb or on stipboard it works very well (but not if it is biult on a breadboard).
Its frequency is fairly stable because it has an RF amplifier to isolate the antenna from the oscillator.
It has a low dropout volage regulator so the mic preamp and oscillator always work properly.
it has pre-emphasis (treble boost0 like all FM radio stations so it sonds great.
