A Very Small and simple one stage adjustable FM Voice Transmitter that transmits all sounds to a remote FM receiver up to 1.4 mile away in the FM 88 to 108 MHz receiver band.
Minimum parts and highly proficient. The .1 uh coil is just a few air wound turns, 3 or 4, wound on a plain ¼ inch drill bit with # 22 copper wire.
Decrease those turns to receive transmissions in the 147 to 174 MHz VHF band. Tune the 22 to 47pF capacitor to bring it into your desired frequency. Use a 16 inch small stranded insulated wire for your antenna.
