I wish to build a small FM transmitter. Nothing fancy, just something that'll transmit over a range of 20m or so with half-decent sound quality. I found the following circuit on the net: What I want to do is take off the electret microphone and replace it with a stereo audio jack. I've made some modifications that I think should work, but I may have got it completely wrong. I'm no good with radio electronics, so I figured I'd ask here first. The potentiometer is there so that I can adjust the pan, but it's not a necessary function. However, I do need to stipulate that I not interfere with other people listening to the radio in the house. Also, my dad has a decent transmitter (a few watts) that runs on 93.4MHz or something that he uses to listen to music around the house or in the garden or garage, and my transmitter mustn't interfere with his.
