I put together this mini FM transmitter. It seems to work because I
can hear the buzz in my radio change whenever I mess with the coil or
the on/off switch. But I can never hear the audio that should be
coming through.

I don't know that much about this type of thing, but I took the mic (I
got it at Radio Shack) and tried to hook it up directly to a speaker
using several different schematics I found for electret mics.

All I got was nothing except for when I attached the battery I can
hear the speaker flutter a bit.

Does this mean I have a bad mic or am I just not hooking it up
properly?
