CorssMode also for ANY<to>DSTAR ??

Post by ApipApip » Sun Jul 31, 2016 3:48 pm

HI

will be possible in the future have not only C4FM and DMR, but all the 3 digital OPENSPOT connector with CROSSMODE mode?

CROSSMODE
CONNECTOR<>MODEM
===================
C4FM<>C4FM-------->OK
C4FM<>DMR--------->OK
C4FM<>DSTAR

DMR<>DMR---------->OK
DMR<>C4FM--------->OK
DMR<>DSTAR

DSTAR<>DSTAR----->OK
DSTAR<>C4FM
DSTAR<>DMR

Already I use only a single RTX for 2 mode, if can do all 3 mode with one radio would be a World fantastic newone!

Regard's

openSPOT only converts the FEC format between DMR and C4FM, as they use the same voice codec. D-STAR uses a different voice codec, so it's not possible to convert it to these modes without a proprietary AMBE IC, which openSPOT does not have. :cry:

The fusion radio is set to Voice Wide and the openSPOT is set to a DMR group. What does the openSPOT do to the Wide Audio form the fusion radio since it is much higher bitrate then the DMR is design to accept?

openSPOT will output silence to the DMR radio when receiving wide audio data.

Can the VW mode be added in the future to the openSPOT? I still get low audio reports when using my FT1DR on DMR, even when the mic gain is at max.

This would go a long way to bringing the audio levels up on Fusion. Hell, even the DV4Mini can handle VW mode...

Wide voice mode is supported on FCS with a C4FM radio. We plan to add support to YSFReflectors, which will also have wide voice mode support with a C4FM radio. DMR does not have wide voice mode, it operates using the same voice codec as C4FM narrow mode. Note that the standard dv4mini does not do cross mode operation.

Thanks for the confirmation on FCS mode VW access, I haven't even tried that yet...
