Cross modes using a C4FM transceiver
Using a D-STAR® network (openSPOT4 Pro only)
After you've set up and activated the D-STAR® connector, switch the modem to C4FM mode (or C4FM Half Deviation mode, if your radio needs that). Only calls in DN (Digital Narrow) mode will be converted, if you transmit in other modes, D-STAR® users will only hear silence.
Note that some (classic) REF and XRF servers need a valid D-STAR® registration. You can read more about this here. Make sure you've set the callsign in your C4FM transceiver to the exact same callsign that you have registered, otherwise servers which require a registered callsign won't accept the connection, or won't let the openSPOT4 to transmit data.
Using a DMR network
After you've set up and activated the DMR connector, switch the modem to C4FM mode (or C4FM Half Deviation mode, if your radio needs that). Only calls in DN (Digital Narrow) mode will be converted, if you transmit in other modes, DMR users will only hear silence.
The source DMR ID of your calls from the C4FM radio will be set to the ID associated with the source callsign. If there's no ID associated, then the source callsign will be parsed into a number and this will be used as the source DMR ID. If it can't be parsed into a number, then the Default cross mode source DMR ID will be used. You can set this to your DMR ID.
The callsign of incoming DMR calls will be set to the callsign associated with the DMR ID. If there's no callsign associated in the database, then the Default callsign for cross mode calls will be used. If it's not set, the callsign will be the source DMR ID as text.
Using an NXDN® network
After you've set up and activated the NXDN® connector, switch the modem to C4FM mode (or C4FM Half Deviation mode, if your radio needs that). Only calls in DN (Digital Narrow) mode will be converted, if you transmit in other modes, NXDN® users will only hear silence.
All C4FM calls will be sent to the Default cross mode destination ID on the NXDN® network.
The source NXDN® ID of your calls from the C4FM radio will be set to the ID associated with the source callsign. If there's no ID associated, then the source callsign will be parsed into a number and this will be used as the source NXDN® ID. If it can't be parsed into a number, then the Default cross mode source ID will be used. The default ID will be used if 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.
The callsign of incoming NXDN® calls will be set to the callsign associated with the NXDN® ID. If there's no callsign associated in the database, then the Default callsign for cross mode calls will be used. If it's not set, the callsign will be the source NXDN® ID as text.
Using a P25 network
After you've set up and activated the P25 connector, switch the modem to C4FM mode (or C4FM Half Deviation mode, if your radio needs that). Only calls in VW (Voice Wide) mode will be converted, if you transmit in other modes, P25 users will only hear silence.
The source P25 ID of your calls from the C4FM radio will be set to the ID associated with the source callsign. If there's no ID associated, then the source callsign will be parsed into a number and this will be used as the source P25 ID. If it can't be parsed into a number, then the Default cross mode source P25 ID will be used. You can set this to your DMR/P25/CCS7 ID.
The callsign of incoming P25 calls will be set to the callsign associated with the P25 ID. If there's no callsign associated in the database, then the Default callsign for cross mode calls will be used. If it's not set, the callsign will be the source P25 ID as text.
