Introduction: Fm Pirate Radio

So you want to do some pirate radio , this is an intro into Micro broadcasting , this little transmitter is capable of transmitting around 500 mW of power over the Fm Broadcast Band (87.5 - 108 Mhz) . So the very basics , what do we have in the picture you might ask ? , well first of all we have a fm modulator that was bought brand new from Jaycar Electronics in Australia , it normally is enclosed in plastic enclosure and has a cigarette lighter attached to the end , well not any more as you can see :) , furthermore when you carefully take it apart you have the FM modulator which is capable of accepting a stereo 3.5 mm input / a sd card input and also included a infrared remote control.

One thing you find with most of these modulators is the lack of range they produce , mainly because of the approval or regulations of the country , well hey the government doesn't want pirates broadcasting in the millions around the country. well most Modulators are labelled with an antenna out , however they direct the signal into a few caps and inductor maybe a resistor and terminate the signal their , what you want to do is re-route the RF from being limited and use your own antenna or in this case into a Rf Amplifier for more bang!! this is only an intro of more posts to come , please feel free to comment to motivate me to post more instructables :) to follow , just to add in the picture is the fm modulator a 12 volt to 5 volt regulator circuit which is included in the modulator this converts your 12v dc car battery's voltage to 5 volts and a nice tv amplifier with 43 db gain to give 500 mW of power out the tv amp has been modified to suit...
