Cross modes
Both the openSPOT4 and the openSPOT4 Pro have a very powerful, yet easy to
use cross mode system.
openSPOT4 Pro
The openSPOT4 Pro has onboard transcoding hardware with a genuine AMBE®
vocoder chip:
The openSPOT4 Pro has the best voice quality in cross mode operation
Supports D-STAR® cross modes
Supports call audio playback on the web interface
The openSPOT4 Pro's onboard transcoding hardware supports the following
cross modes:
You can use your DMR transceiver to access D-STAR®, C4FM, NXDN®
networks
You can use your D-STAR® transceiver to access DMR, C4FM, NXDN®
networks
You can use your C4FM transceiver to access D-STAR®, DMR, NXDN®,
P25 networks
You can use your NXDN® transceiver to access D-STAR®
,
DMR, C4FM**
networks
You can use your P25 transceiver to access C4FM networks
A software-based conversion method is used for the following cross modes:
C4FM transceiver to access P25 networks
P25 transceiver to access C4FM networks
openSPOT4
The openSPOT4 uses a software-based conversion method, which supports the
following cross modes:
You can use your DMR transceiver to access C4FM, NXDN® networks
You can use your C4FM transceiver to access DMR, NXDN®, P25 networks
You can use your NXDN® transceiver to access DMR, C4FM networks
You can use your P25 transceiver to access C4FM networks
Note that as the standard (non-Pro) version of the openSPOT4 has no onboard
transcoding hardware, it can't change the audio level of the transcoded stream.
This may cause you to hear others loudly, but others hear you quietly, or vice-
versa.
