  • Page 18 DMR transceiver DMR usage notes There are two basic types of DMR calls your transceiver can transmit or receive: private and group. The openSPOT4 forwards what it receives from your radio to the network, or from the network to your radio. The network may forward your calls to its other connected stations (hotspots/repeaters/gateways) or calls from other connected stations to you based on linked talkgroups and reflectors.
  • Page 19 DMR transceiver Static talkgroups on DMRplus/IPSC/other networks You can define what TGs to link statically at the DMRplus options section at the bottom of the Homebrew/MMDVM® connector settings page.
  • Page 20 DMR transceiver Reflectors Reflector IDs are between DMR ID 4000 and 5000. To link a reflector, start a short private call to the reflector ID. To unlink the reflector, start a short private call to DMR ID 4000. Only 1 reflector can be linked at a time. To talk on the linked reflector, send your calls to DMR ID 9 with a group call (TG9).
  • Page 21 DMR transceiver To unlink the currently linked module, call DMR ID 4000. To connect to module A, call DMR ID 4001, for module B call DMR ID 4002 and so on. Example If you have TG969 linked either dynamically or statically, then the server will forward group calls (coming from other stations (repeaters, hotspots, gateways)) going to DMR ID 969 to your openSPOT4.

About the dejitter queue All packets received from the network will go to this queue to eliminate network jitter. If the dejitter queue length is too short, the graph's line can touch zero during a call and the audio can stop for a moment as the modem runs out of frames to transmit.

  • Page 46: Connectors Page

    DMR transceiver Connectors page In openSPOT4 terms, a connector is the protocol which you use to connect the openSPOT4 to a server. The easiest way to choose which connector to select is using the Quick Setup. You can activate a connector by selecting it from the Edit connector list and clicking on the Switch to selected button.
  • Page 47 DMR transceiver This section is only available if Advanced mode is enabled. By setting the Change to Null connector after last call other than 0 will change the active connector to the Null connector after the last received call (minimum timeout value is 5 minutes). For example, if you set a timeout of 600 seconds, openSPOT4 will change to the Null connector if there is no call received in the last 10 minutes.

  • Page 48: Modem Page

    DMR transceiver Modem page You can change the modem settings on this page. If Advanced mode is turned off, both RX and TX frequencies will be automatically set to the same value (the separate RX and TX frequency fields will be hidden). If the Idle modem mode is activated then the openSPOT4's modem won't transmit and will ignore all received transmissions.
  • Page 49 DMR transceiver You can set a CW ID which the openSPOT4 will transmit at the specified interval with the specified speed. You can use letters, numbers, slash (/) and space characters in the ID. The openSPOT4 transmits an unmodulated carrier wave by default, so you'll only be able to hear it using a radio which is capable of CW/SSB demodulation.
  • Page 50 DMR transceiver The Ignore RX after TX setting specifies a time for which all received frames by the modem will be ignored after the last TX has ended. This is useful if you want to use the openSPOT4 to link a repeater to the internet through RF and the repeater has a lengthy internal buffer and it is still transmitting even after the openSPOT4 has finished transmitting (which means the openSPOT4 will start receiving its own stream again).

  • Page 51: Settings Page

    DMR transceiver Settings page You can change the general settings of the openSPOT4 on this page. Configuration profile The openSPOT4 stores all its configuration in individual profiles. There are 5 of them, and profile #1 is active by default. Initially all configuration profiles have the factory default settings.

  • Page 52: Firmware Upgrade

    DMR transceiver By setting the Change after last call setting to non-zero (this setting is available if Advanced mode is enabled), the openSPOT4 will switch to the specified profile slot after a timeout since the last call was received. If the Always use profile #1 on power on setting is enabled, then the profile #1 will always be loaded when powering on the device.

  • Page 53: Location Settings

    DMR transceiver Modem mode notes: DMR: voice announcements are sent to TG9, so to hear them, make sure you have TG9 in your radio's RX group list. NXDN®: voice announcements are sent to TG0.
