FM Wireless Microphone by BC557

FM Wireless Microphone has been a very popular project with beginners and experienced constructors alike. It has been used inside guitars and as the basis of a remote control system. I do however, receive many requests for a higher powered circuit and better microphone sensitivity. Now I can introduce the new FM Wireless Microphone (v5), which also has a better frequency stability, over 1Km range (under ideal conditions) and is good on microphone sensitivity. This has been achieved by adding an RF amplifier buffer (with 10dB gain) and an AF preamplifier to boost the modulation a little.

9 Volt FM Transmitter Kit by BC338

This new 9 Volt FM Transmitter Kit 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 – DIY Kit 18.

Specifications:

* L: 1-3/4″ W: 7/8″ H: 1/2″
* Requires 9 Volt Battery
* Transmission frequency is user selectable.
* Transmitter can be listened to on any FM radio.
