a more stable voice transmitter

[Overclocked]

Instead of making a mono FM transmitter toy that drifts its RF frequency, why not make a Stereo Micromitter that uses a modern IC with a crystal controlled frequency synthesizer and a phase-locked-loop for stability.

Lol, Ive read a couple posts around here that showed that link.

There was a transmitter I found that was made by micrel, MICRF103 (transmit) and MICRF005 (reciever), but they can only be used with digital, and run from 800Mhz to 1Ghz
