Well, if you got real sneaky you could have the PIC generate a PWM signal
that you filter to control its own VCO frequency. Then you could have a
serial interface to the PIC to send commands to change the frequency. Then
your control program just needs to know how to fiddle the baud rate
generation to keep listening to the serial data to receive commands  to
change the PWM signal.

Sounds like it should all fit into a 12F6xx ;)))))))))))0
