Hm okay you're right - I can't find the BA1404 in any of the shops I usually buy parts. I'll think about this Micromitter project, maybe i find some time to build it. Thx once more.

Well, I'm interested in making one myself @Sasi, but to be honest the Micromitter project posted by audioguru is way too big for me... Is there a way to make an easier transmitter which works fine, or rather is the BA1404 really as bad as you say, audioguru? Thx for your help!

I got a question here: There are commercial FM-transmitters (e.g. from Apple) which send a few meters. I'd like to build such one and don't want to bother others on the highway by hearing crazy music from my ipod in my oldschool car radio :D Does somebody know about a schematic to this kinda FM-transmitter? This transmitter looks nice to me because of the easy way to build inductors :D http://w1.859.telia.com/~u85920178/tx/bug5.htm but up to 1km range is quite a bit too good for me ;) Sry for my English Greets, Br4in
