High Quality 9 Volt FM Transmitter Kit

High Quality 9 Volt FM Transmitter Kit

The original CK217 was an improvement on the CK200 FM Transmitter. This new FM Transmitter can transmit over 900 feet in the open depending on aerial used. The tank oscillator coil is built into the circuit board, and has been tinkered with to give the best distance and stability for it's size. The battery supply rails have been well tied together with respect to radio frequencies. The tracks are also thicker making the fm transmitter circuit a single 'solid' block eliminating RF currents in different parts of the circuit. This also means the battery no longer has RF on it which makes the whole unit a lot more frequency stable.Can be tuned anywhere in FM band.

High Quality 9 Volt FM Transmitter Kit Reviews:

  • --> I received this kit directly from the manufacturer (Hong Kong) because another FM transmitter kit (Kit 7) did not work. The instruction were easy to follow but the information on the antenna was Chinese to a novice like me. In the end, it only worked at a foot distance or so from the receiver. Quite a disappointement!
