FM Tracking (1 transistor) transmitter schematic

OK, here's the schematic of the FM tracking transmitter I discussed earlier. It's called "tracking" because its original purpose is to be put into a model rocket, then use an FM receiver to track down the rocket after it lands. The basic oscillator / transmitter is unchanged from the web site I listed earlier. I added the FM modulator section and changed up the oscillator and pulse timer part to suit that change.

Revision 3/15/2010 - The diode used in the modulator should be a 1N4148, not 1N4848.  In other words, a common small signal silicon diode.  Sorry about that write-o.
