First off: You need at least two things:
Mr. Microphone offers both these features in a small package.
But you won't transmit past 300 yards at best.
You will be legal with mr.microphone.
For those who are serious about becomming a pirate broadcaster:
A little package from Smart Kit Electronics offers the same benifits
as mr.microphone; except:
1). It's not packaged up all pretty to look like a microphone.
2). You will not be legal. You will be verry illegal
The Smart Kit 1009 FM TRANSMITTER:
This Transmitter will do 1 to 2 watts depending on how much power
( 9 - 30 vdc 400ma) you deliver to it.
This is provideing that you make a proper solder bridge (not shown on instructions) if needed.
Look at the back of the board at the main antenna connection jumper & you will figure it out.
A 9 volt radio battery is fine for about 1 watt.
12 Volts is better
I now reccomend a lawn & garden or a motorcycle battery but...
If you connect two 6 volt lantern batteries in series
(connect the negative from battery a to the positive of battery b)
you will have a long-life 12 volt battery for your transmitter.
This is much smaller, lighter, safer and easier than trying to carry a car battery.
Eveready also makes a 12v lantern battery in two flavors classic and energizer.
You Can Use Alligator Clips
to connect the transmitter to
The 1009 FM with
the alligator clips
and a 5/8 wave
made of wire.
*I used to reccomend attaching a microphone with
plenty of mic wire to the transmitter.
*I Don't reccomend this anymore as the mic cable
effects the range of the transmitter in a bad way.
Im not saying that an electronics expert couldn't develop a feed useing diodes or something but...
Stick with the condenser mic that comes with the kit
mounted directly to the circuit board.
Place a speaker inside your inclosure and run the wire from
this speaker. Not from the transmitter itself.
Adjust the trimmer (VR 1) so that the mic isn't so sensitave.
