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!
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.

Features of VMR6512 Hi-Fi Audio FM transmitter
Broadcasts sound without any external components.
Audio frequency processed by DSP, providing high quality sound.
Using frequency synthetic technology, high stability of oscillation
frequency and output power adjustments.
Frequency range is 88.0MHz to 108.0MHz, low -end can be extended to
76.0MHz upon request.
It can input analog audio or digital audio and possesses external UART
interface and can be easily controlled by external CPU or PC machines.
It provides frequency setting UP / DOWN input and can be used
This is the most simplest and single transistor FM wireless transmitter
circuit that ever posted in CircuitsGallery . In telecommunication
field, frequency modulation (FM)
transmits information by changing the frequency of a carrier wave
according to message signal. FM uses VHF radio frequencies usually 87.5
– 108.0 MHz to transmit and
receive the FM signals.
Here I will give you the explanations about FM transmitter, how to make
a FM transmitter and how a simple FM transmitter is designed and
assembled etc. The
performance and working of a wireless audio transmitter circuit mainly
depends on inductor coil specification and the value of variable
capacitor. Even a slight change of
inductance or capacitor can shift the harmonic frequency from the VHF
(88 -108 MHz) band. This article will enable you to answer “how to build
an FM radio
transmitter?”. Also you will get the confidence to build your own FM
