Digital Speech Decoder
On Sunday 12 October 2014, I was informe of a software project called Digital Speech Decoder (DSD). The project claims that “Digital Speech Decoder is an open source software package that decodes several digital speech formats” — http://wiki.radioreference.com/index.php/Digital_Speech_Decoder_%28software_package%29
At the time of writing (version 1.7) supported the following
P25 Phase 1
ProVoice EDACS Digital voice
X2-TDMA – Motorola public safety TDMA system with P25 style signaling (mostly based on DMR)
DMR/MOTOTRBO – Digital Mobile Radio standard
NXDN – 9600 baud (12.5 kHz) NEXEDGE and 4800 baud (6.25 kHz) NEXEDGE/IDAS
D-STAR – The Github version of dsd/mbelib can parse and play back D-STAR traffic.
C4FM modulation (such as Yaesu System Fusion)
GFSK modulation (including GMSK and other filtered 2/4 level FSK)
QPSK modulation (sometimes marketed as “LSM”)
