Andreas Eversberg b32e0ab602 Implementation of RX level squelch (for A-Netz and B-Netz) 
Use -S <dB> for setting RF level or use -S auto for auto level.

When squelch closes, audio is muted. If squelch is closed for some
seconds (depending on network), call is released. (RF loss condition)

The previous loss detection has been removed

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!
