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.
PiNumberStation is a python/bash coded frontend 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. See: http://en.wikipedia.org/wiki/Numbers_station
#Installation:
- git clone https://github.com/korn101/PiNumberStation with SSH or Terminal
- cd PiNumberStation
- sudo nano PiNS.py
- Change desired parameters in default.ini:
- To begin transmitting message:
- with default configurations (default.ini)
sudo python PiNS.py - with custom configuration (yourcfg.ini)
sudo python PiNS.py yourcfg.ini
- with default configurations (default.ini)
Important: Due to copyright and filesize reasons, no voice/speech files are present. Loading these files is easy. Important to note is the files must be 16-bit Mono WAV files. With a file structure such that:
The folder "vo" contains sub-folders: "misc" and "alpha".
- where misc contains buzzer.wav
- where alpha containts alpha.wav, bravo.wav, etc.
- For NATO Phonetic, I would suggest: https://www.freesound.org/people/Corsica_S/packs/14153/
