Mike Osc AM radio transmitter?
#16

I did some experimenting with things tonite and found I can only go down to about 1050, or up to 1600. I notice the higher I set the frequency, the more stable it seems. It likes 1580 most. I don't notice it fading anymore. I think I need to solder a small control inside and set it, or use a portable CD player to modulate with the volume control. Not real proud of this, but should be good enough to use to test with. I think this was some kind of lab project for experiments or something, certainly not something you want just anyone playing with. Since I didn't have a schematic, I drew one.
