A powerful little electronic circuit with surprisingly good audio
quality. Can transmit up to 3/4 of a mile in open spaces. This is one of the most powerful FM
transmitters that you can legally purchase. An electret microphone is used to add
sensitivity. The circuit comes with a nine volt battery plug, but can operate on 6 to 12
volts DC. Greatest output is at 12 volts, but stay with 9 volts to be legal. PCB is only
3/4" wide by 2-3/4" long.
