Wireless FM microphone kit

This wireless FM microphone kit is intended for hobbyists, students and educators who want a simple hands-on radio project. It transmits voice over FM so a nearby receiver can pick up the signal for karaoke, classroom amplification or experimental learning. The kit arrives as electronic components for self-assembly.

Handheld bi-directional transmitter

The handheld microphone uses a bi-directional figure-8 polar pattern and runs on a single 1.5 V AA battery, which is not included. Its wireless design means no cables to a mixer or amplifier, so users can move freely within the 20 to 30 metre effective range while speaking or singing. Assembly requires basic soldering tools and electronics knowledge.

DIY upgrade from wired microphone

This kit replaces a tethered handheld microphone when the user wants wireless freedom without a professional UHF system. The jump is worth it for classroom demonstrations, home karaoke practice or radio hobby projects where a 20 to 30 metre FM link is sufficient and the builder is comfortable constructing the circuit from discrete parts.
