Schematics - Fm transmitters
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 generally suck, 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.

Professional 15W FM transmitter/exciter board; MAX PRO 3+

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).

Professional 15W FM transmitter/exciter with DSP and RDS encoders; CyberMaxFM+ 15W

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.

Small FM bug
Small and simple FM transmitter. Low cost low quality bug.

PC FM transmitter card for your PC
Insert this into your PC (PCI slot) and turn your PC into a local radio station. Play music to your community, start your own small FM radio station, also great for outdoor cinema, advertising, realltor radio, convenient wireless translation, guided tours...
Optional RDS encoders and 15W or 300W amplifiers are awailable!

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!

Schematics - FM VCO designs
VCO I
This is a very cool VCO of professional FM transmitter. I am sure the design itself gives some ideas to you as how to design VCOs.

Professional 15W FM transmitter/exciter board; MAX PRO 3+

VCO II
Another VCO. It is originally made for 2m station, but is perfect for FM radio band as well. The mosfet serves as PLL mixer. If you want to use direct synthesis method, change this mosfet into buffer. Very clean signal, but it is narrowband. It has to be tuned every time you change frequency.

Schematics - FM amplifiers
Amplifier I
Hook this one to any above VCO and voila, you have a 4W FM LPFM transmitter.

General purpose amplifiers
This is a link to another page that containes detailed instructions for an amplifiers as well as a couple of other interesting designs from Motorola.

C class amplifier
RF amplifier, usable for FM radio and other applications. It is NOT suitable for AM.

Schematics - Stereo encoders
Stereo encoder I
From Internet, it has been circulating around for ages.

Stereo encoder II
...another cool stereo encoder schematic. Looks better than the above model. It has a bit of noise, filtering is not sufficient, but otherwise it can be made to work extremely nicely. Substitute XR2208!

Professional 15W FM transmitter/exciter with DSP and RDS encoders; CyberMaxFM+ 15W

Stereo encoder III
Yet another cool stereo encoder schematic. What can I say, it definitely works as I have tried it out. Has some hard to find parts.

Stereo encoder IV from BiasComms
Another simple and working stereo encoder from Bias Comm, a nice one...

Schematics - RDS encoders
RDS encoder from Internet
From Inet, its been circuling around for ages. I made it a little bit more readable for you guys.

And the required program
This is the program that's supposed to be used with RDS encoder, but It doesn't work on my PC. Supposedly it works on older machines. A fix exists on the internet so look around or ask in the forum.
