Transmitting iphone music via Fm transmitter

JMD1:
Who cares if its illegal? ....... How would care for legality? Its EU here and I dont mean Germany of France or any big country.

So for one I care, if you want to play about with transmitters then their are legal ways to do it in the form of ham radio. You are too stupid to know of any RF pollution you can generate and it could cost a life if you interfere with things like rescue communications. It seems like you want to have the advantages of EU protection without the responsibility of obeying the law. The fact that you believe you are not likely to get caught is a morally corrupt undefensible stance.

Didn't know the FCC permitted small untested unlicensed tx's - presumably only in certain bands. Not true in the UK. Even in the US wouldn't it be wise to have somebody measure the power before using it to avoid problems?

In the US (and apparently Canada) one can buy wireless FM transmitters like the circuit in post #1 in kit form.

e.g. : FM Transmitter for Beginners

Unless one deviates from the circuit design, the power output will be limited. I built these sorts of kits as a kid.
