doc Posted January 24, 2005 Report Share Posted January 24, 2005 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.greetsDoc Quote Link to comment Share on other sites More sharing options...

doc Posted January 25, 2005 Report Share Posted January 25, 2005 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 .... ;Dgreets Doc Quote Link to comment Share on other sites More sharing options...
