one of these kiddie 5 dollar mircrophones that can "hear your voice on any FM frequency/radio"? well, what if i wired one of those suckers to a board of an old radio- where should I wire it?! think I could broadcast to other radios?

wire it and give me updates, and when you hook it up to a radio use a big ass antenna and also try broadcasting on AM

I take it you want to use the mike for covert use! Correct?

What you suggested wont work as:

If you were to wire it up to an old CB radio not only would it not be covert you also have the problem of the CBs internals needing around 12-13.8 Volts.

This would require either-
A: a car battery
B: a power supply

Which would also make the radio even less covert.

Also a radio is only as good as its aerial which needs to be tuned for the frequency to provide low SWR to gain effectiveness.

If you tell me in a bit more detail i may be able to help you with your idea.

Warweed, your reply made no sense.

And by the way, it's "modulation", not modification. But you knew that...

It sounds like you are trying to hook up a microtransmitter to an amplifier. Basically it would be easiest to just buy a transmitter.

There is a way i can make a microtransmitter or FM bug transmit 20-30 miles but it just depends how serious you are and how much money you have got!

I dont think you would have the resources as you only want to hook up a cheap $5 transmitter to an OLD CB radio board. So i wont go in to how you can do it unless you really want me to cause im tired and the less i type the better right at the moment!

Sorry about that .. i had just woken up it was 5 AM and well yeah i had a buddy telling me stuff while i was typing sorry about that

any was cheers

Yeah you could send a 20mw signal 20-30 miles, if you had a 50 element antenna.

No even with a 50 element beam you couldnt transmit that distance with a FM transmitter that works on the 88-108Mhz running 20mw.

I have got a 21 element Yagi beam and running that power on that band i would only expect about 2 miles. And besides a 50 element beam is not what you would call covert!

But i do know how to get that range with that device while still making it covert and only running 20mw. But like i said you will need to have a few things and i doubt the starter of this post is willing nor has the money to do it, so i wont worry about explaining how to do it.

Who said anything about covert.

Sorry my mistake! Yes i do admit when im wrong. I just assumed he was trying to build a covert transmitter with more power to get a larger recieve range.

The reason i "assumed" this is because the only devices in Australia that im aware of that transmit on the FM broadcast band, 88-108 mhz are bugs! They are classed as a LIPD (Low Interferance Potential Device).

The original post wasnt exactly packed with information or specifications or what he even wanted to acheive. He said,kiddie microphone. A microphone is a one way thing, ie not a tranceiver. Which led me to beleive he was trying to make a powerful bug.

After reading the post again he may even be trying to set up a pirate FM broadcast station. Im not quite sure. If the creator of the post can supply a bit more information im sure we could all help him in his quest

It's hella easy to set up an am broadcast/clandestine station if you know what your doing. Using my ft-107m and a random wire I managed to jam radio disney. That cost less than $350 american. I've seen ts-520's go for $150 and I'm pretty sure that those have 160m on them.
