I've come across this circuit a few times while searching for simple transmitter circuits, and decided to try it.
According to this site, it should be transmitting at around 90Mhz.
I feel like I've followed the instructions to the letter, yet I have no results when chasing the dial on my radio.
Here are some photos of the circuit I have constructed.
I've tried just about every area of the dial and fiddled with the coils. No effect or "quiet spot".
I have changed the coil so that it is a single coil tapped at the 6th loop. I am now getting some effect, but it's not what I expected.
When I pinch the coil together, it seems to drown out whatever FM station I am on. I can't seem to narrow it down to one frequency. If I hold the coil together, it will add static or a faint whistling to any station. The range is also very poor; the phenomena occurs at a max of 3 feet away from my radio with the 12" antenna. If I use myself as an antenna(holding on to the antenna wire), I can create the effect from the other side of the room. Is this a good sign or am I fooling myself?
See my answer.
