Low Power FM Transmitter Kit

The most powerful FM Transmitter circuit we've seen that operates on such low voltage (just two AA cells). A range of 200 ft can be expected and, given a good antenna and FM receiver, over 1/4 mile can be expected. An external power supply can be used up to 9 volts. Transmits to the FM radio band, which means you can use any FM radio to receive the transmitter. Teaches basics of FM transmitters. Microphone is included - DIY Kit 7.

Also see CK217 our longer range version of this kit.

Specifications:

  • L: 1-3/4" W: 3/4" H: 1/2"
  • Requires 2 AA batteries (holder included, not shown in pic.) 9 volt battery can be used to increase range. (or Use this Power Supply instead of a Battery) 
  • FM Transmitter frequency is user selectable.
  • Transmitter can be listened to on any FM radio.
