Hi there
Can DSDPLUS decode p25 TDMA trunk voice channel with audio feed that it get from SDR receiver without using the FMP2 Program ?

The idea is to listen to a fixed voice channel and hear its traffic and monitor the data when the oudio is supplied from an SDR receiver to the dsd software just like it do to DMR as example ?
has someone tried it ?
When i try it no data is displaying like no audio is supplied
but when the Receiver is listenning to control channel the dsd show data
any advices ideas welcome
Thanks Forward

No. P25 Phase II TDMA decoding requires FMP24 (or FMPA or FMPP) as the tuner with TCP link to DSD+.

Added P25 Phase II trunktracking and voice decoding

Requirements

- a full CC plus VC trunktracking DSD+ setup,
i.e. CC and VC signal sources and CC DSD+ and VC DSD+ instances running

- CC side can be any P25 control channel signal source feeding CC DSD+
(tapped scanner, RTL dongle, Airspy, etc., FMP24, FMPA, SDR#, etc.)

- VC side MUST be an RTL dongle controlled by FMP24 or an Airspy controlled by FMPA

- VC side MUST use TCP linking between FMPA/FMP24 and VC DSD+
