Continuously calculate noise floor and lower threshold level if less noise was received. High noise or ongoing transmission during start of program will not cause a threshold that is too far above the actual noise floor. |

README
This software implements base station protocol of classic mobile phones. With radio transmitter and receiver connected to one sound card and a headset connected to another sound card, it is possible to make and receive calls to and from mobile phone. Currently supported networks: * A-Netz * B-Netz (ATF-1) * C-Netz * NMT 450 / 900 (Nordic Mobile Telephone) * AMPS (Advanced Mobile Phone System) * TACS (Total Access Communication System) * Radiocom 2000 (French network) USE AT YOUR OWN RISK!
