Default In Car RF Transmitter

Hi. I'm trying to build myself an in-car radio transmitter, which I will
plug the headphone feed of my Mini-Disc player into, so that I can tune
the car radio in and listen to it.

I've tried a few circuits but so far no luck. I'm testing building on a
breadboard and in the home.

Does anyone know of any successful circuits of this nature, and have any
pointers to them?

Thanks.

You could try getting hold of one of the 'micromitter' kits that have
been put together for a Silicon Chip project published in the December
2002 issue of Silicon Chip magazine.

It is a low power broadcast band stereo FM transmitter. Seems to be just
what you are after. The spec's say it runs off 4 to 6 volts DC, pulling
28 mA at 5 volts.

I think the kits are carried by Jaycar Electronics and
possibly even Dick Smith Electronics stores here in Australia.
Alternatively if you are game enough to try etching your own circuit
board to build the thing on, the board layout is published in the article,
along with complete parts list, circuit diagram and description of how it
works and how to set it up.
