Crystal Controlled FM Transmitter Circuit - 150xt

The 150xt Crystal Controlled transmitter circuit shown below has been produced in quite a few configurations. It is highly unique and will accept voltages from around 2V to almost 6 volts with no circuit changes. I have surface mounted it from the size of a postage stamp in the past and it is highly stable. It was one that saw much action back in my days and was built for quite a few drug squads and task forces.
