From GigaWolf:
PiNumberStation is a python/bash coded front end that takes string messages and turns them into basic speech (preferably NATO phonetic alphabet or Combine VO) – this message is then passed over FM Radio transmission via a small antenna connected to GPIO pin 4. The hard part (modulating the sound and sending it to the antenna) is actually done by the back-end PiFM based C program.
The end result is a basic and very small FM Number Station that with adequate tweaking has the potential to be very powerful.
Legal Notice: The operation of an FM Transmitter (over a certain energy level) is in almost all countries and local jurisdictions illegal. Check the laws of your area before operating such a device.
