Default Tracking Transmitter/FM Radio Receiver
I'm looking for a 1.5 or 3Vdc Tracking Transmitter diagram. I have located several that use a LM3909 IC, unfortunately that IC has been discontined. There are 2,3 and 4 transistor designs out there but I am not sure how realiable or accurate the frequncy will be? Anybody got any ideas?

Good idea, I need it to be really small and light.

Thanks for the link.
