i know this is not related with midi, but could u help me please
i listen to music on the net but my hi-fi is to distant from my computer too run cables between !
so i want to build me a radio FM transmitter to plug into my sound card headphones jack !!!
i’ve found some schematics on the net, but..
due to my lack of knowledge in electronics i cant choose the best !!
PLEASE HELP ME and point me to the best project !!
i need no more than 50 meters of trasmission but it MUST be in very good quality .
the parts must be as common as possible with no hard-to find.
it should be operated by batteries.. best = 1.5v but also possible 3v and 9v.
of course it MUST be a stereo.
posibility to change" station" (=fm frequency).
with NO frequency loss on the way = sound received must be exactly the same as “sound in”
oh yes.. it should be simple to build as i m only a hobbeist
thanx

Hi,
it’s not really simple to build such a transmitter for a hobbiest. In fact that there are many ready solutions for small money on the market.
For example: VIVANCO. It’s about 70€ in excellent quality with batterie boxes in stereo.
You won’t be able to build that for that money.

Hi,
ok. 70 Euros is a lot of money…
I don’t know the chips used in your applications. One thing you should keep in mind:
Is it legal in your country to send in the FM Band ?
- You will get a lot of trouble in the FM Band (in my country). Profesional wireless systems are using other (higher) frequencies.
(The VIVANCO Set uses 868 MHz)
- The quality of DIY FM transmissions are normally poor (I did it once but the result was lousy !). No diversity. A lot of noise, and so on.
The cheapest way for your problem is a long cable … ;D
