Simple FM Wireless Microphone
Simple FM wireless microphone can transmit up to 90 MHz of radio frequency and adjustable by tuning the inductor. This design is able to avoid the local FM radio frequency and set up its own range of radio frequency.
Influence
The distance and the frequency are influence by the wireless module, inductance, spacious of the surrounding, electromagnetic interference, and sensitivity of the receiver.
Specifications
Radio frequency : 80 MHz – 108 MHz
Circuit voltage : 3V – 6V DC
Transmission range : 10 – 50 meters (depends on the surrounding)
