AM/FM Transmitter schematics from simple to hard.. « Thread Started on Dec 19, 2007, 10:01pm »
WARNING: Lots of pictures, wait for them to all load...
Schematics to keep you all busy. Here I have added several links to basic simple radio transmitters to more complex ones like stereo FM and PA amp sections. This thread will be updated periodically with more schematics over time. Last update on: May 23, 2009.
If you have a schematic or project of your own feel welcome to post a link/picture here.
Most basic FM transmitters/bugs you could build aka-"toys"
Simple 2 transistor (mod/osc) FM bug type transmitter...

Sweet thanks! any have a schem on a 1-10watt varibale output fm amp?
I know this is kind of an old post but I think you can just use a variable resistor from the output of your buffer going into the RF amp section. If you need some more details I could write up an example schematic of how I would go about doing that.
