hi all,

I'm really new to electronics and thought I would start by buying a few kits before I started any courses.

Made a few all ok and modified a couple successfully however this one has stumped me.

I am making this circuit BA1404 HI-FI Stereo FM Transmitter

now everything is fine until I go to connect the plug that will plug into the mp3 player etc. I could understand if there was just a left, right and a ground but I can see a ground for both the left and the right. How do you do this when there is only one ground wire from the rc adaptor.

thanks heaps,

Shags

The BA1404 IC is obsolete and has not been made for about 8 years. Its performance was so bad that it was replaced by a new line of ICs with modern circuitry.

The Micromitter kit uses one of the new ICs and so do most MP3 to car radio FM stereo transmitter products.
