Hi, I am trying to make a short range(around 50 - 100 meters) fm transmitter and found this simple one on the web(simplest transmitter.png). I want it to have different input options 1. the jack, 2. regular microphone, and then I wanted to have a sonic ear type amplified mic for the third option. I thought If I put a switch which had three inputs I could do that. However for the mic I would need an extra transistor to ampliphy it a little right? How would I do that? Also, I would like to attach an anttena but I don't understand how I would attach it because there is a ground connection with it. I have never heard of an anttena with polarity? "My version" is sort of my idea of how I think i could be but I need help.
