simple FM transmitter.


Recommended Posts

This one is from our Projects section (RF Circuits) and is very simple.
Too simple because its radio frequency will change if something gets near it, if its battery voltage gets less and if the temperature changes. It doesn't have the treble boost that FM and TV stations have so its sound will not have enough treble when heard on an FM radio.

When you reply here, click on "Additional Options" then attach your FM transmitter schematics to your reply. If they are already posted at a site then please provide a link to the site.

Model aircraft, cars and boats use "servo" assemblies that have a motor, electronic circuit and pot for position feedback that are controlled with Pulse-Width-Modulation. You can find their circuits by searching at www.google.com .
