Cross modes using a DMR transceiver

Using a D-STAR® network

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 a NXDN® network

After you've set up and activated the NXDN® connector, switch the modem to DMR mode.

The source NXDN® ID of your DMR calls will be set to the same value as the DMR call unless the Always use this ID in cross mode setting is enabled for the Default cross mode source ID on the Settings page, NXDN® settings section.

Your DMR calls will be sent to the same NXDN® ID as the DMR call's destination ID unless the Always use this ID in cross mode setting is enabled for the Default cross mode destination ID on the Settings page, NXDN® settings section, or the destination DMR ID is out of the NXDN® ID range (0-65535). In this case, the Default cross mode destination ID will be used for the NXDN® call.

The destination and source DMR IDs for an incoming NXDN® call will be set to the same value as the incoming call's destination and source ID unless the Always use this ID in cross mode setting is enabled for the destination/source NXDN® IDs on the Settings page, NXDN® settings section.

Make sure the destination ID of the NXDN® calls (the NXDN® talkgroup) 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.
