 World's
simplest FM transmitter schematic, period.
If
you cannot assemble this transmitter, then perhaps you should give
up on assembling anything at all;-) Range and stability
is not premium, but it works! Its a demonstration of what can be
done with little to none resources. Please, don't bother asking
how you could increase the power of this small FM transmitter.

 1W
PLL FM transmitter schematic
Cool little FM transmitter.
Suitable for study purposes, you can use the RF part of this transmitter
easily for your projects. However, unless you know how to build
a serial data link and connect this LPFM transmitter to a PC or
a microcontroller, you won't be able to use the PLL. All info about
the PLL is available at Plessey's web page.

 2W
FM transmitter schematic
This
is a bit more complicated transmitter, but gives a mile of range
or so. You have to understand that it radiates god knows where,
you will be making a lot of interference! This is probably the simplest
2W FM transmitter out there. Keep those two transistors cool, they
can die quickly in this circuit. Don't forget that there is no such
thing as a free lunch, stability and spectral purity suck. But range
is significant (watch those feds).

 Modified
2m VCO/PLL
This used to be a
144MHz FM transmitter,
but it can be modified for FM broadcasting. Here are the VCO,
the PLL and the block
diagram. Don't ask if you don't know what to do with those,
this is for someone who knows a bit about basics.

 FET
FM transmitter schematic
This FM
transmitter makes for a nice project. No PLL, but stability
is excellent. Does have spectral purity problems, though'. An additional
filter is recommended. Giving some 400-1000mW.

Turn your
PC (monitor) into an AM radio transmitter,
Only works in Linux, but you can actually play an MP3 on your
PC and hear it on radio without any extra hardware!!

NEW:
World's simplest FM transmitter II, upgraded!
many of you out there complained 7413 is not easy to come by.
We have revised the world's simplest FM transmitter to use new,
easily available parts. This design is also better as far as stability
and output power goes. Enjoy this small and easy to assemble FM
transmitter! Keep us posted, post your results in the forum!
