Cross modes using a DMR transceiver
Using a D-STAR® network (openSPOT4 Pro only)
After you've set up and activated the D-STAR® connector, switch the modem to
DMR mode.
Your outgoing callsign will be the callsign associated with the DMR source ID. If
there's no callsign associated to the ID, then the callsign will be the Default
callsign for cross mode calls. If this is not set, your outgoing callsign will be your
radio's DMR ID as text.
An incoming call's source DMR ID will be set to the ID associated with the
source callsign. If there's no ID associated, and the source callsign can be parsed
into a number, it will be used as the source DMR ID. Otherwise the Default cross
mode source DMR ID will be used.
All calls coming from the D-STAR® network will be sent as a group call to DMR
ID 9 (TG9). Make sure TG9 is the TX contact of your DMR radio's current
channel, or it's in an RX group list which is assigned to the current channel in
the radio, otherwise the squelch won't open and you won't hear the calls.
Using a C4FM network
After you've set up and activated the C4FM connector, switch the modem to
DMR mode. Only calls in DN (Digital Narrow) mode will be converted to your
DMR radio. If someone transmits in other modes on the C4FM network, you will
hear silence on your DMR radio.
Your outgoing callsign will be the callsign associated with the DMR source ID. If
there's no callsign associated to the ID, then the callsign will be the Default
callsign for cross mode calls. If this is not set, your outgoing callsign will be your
radio's DMR ID as text.
An incoming call's source DMR ID will be set to the ID associated with the
source callsign. If there's no ID associated, and the source callsign can be parsed
into a number, it will be used as the source DMR ID. Otherwise the Default cross
mode source DMR ID will be used.
All calls coming from the C4FM network will be sent as a group call to DMR ID 9
(TG9). Make sure TG9 is the TX contact of your DMR radio's current channel, or
it's in an RX group list which is assigned to the current channel in the radio,
otherwise the squelch won't open and you won't hear the calls.
Using an NXDN® network
After you've set up and activated the NXDN® connector, switch the modem to
DMR mode.
