Setting up your transceiver

Here are some tips on setting up different types of transceivers.

DMR radio setup

  • Set up a simplex channel (with the same RX and TX frequencies). You can set the timeslot to any value, as it is not used in simplex mode.
  • Set the channel's color code to the openSPOT2's color code (by default it's 1, it can be changed on the Settings page, DMR settings section).
  • Set the TX contact for the current channel to the talkgroup you want to talk on. If you want to use a reflector, or Homebrew call rerouting, set it to ID 9 with a group call (which means TG9).
  • Create an RX group list and add TG9 to it. Assign this RX group list to the previously created simplex channel. This way you'll be able to hear the openSPOT2's voice announcements, which will be sent to TG9.
  • Create a contact with private call to ID 9999, which is the openSPOT2's built-in local echo service. Make a call to this ID to test the connection between the transceiver and the openSPOT2.
  • Run AutoCal in case you have voice quality issues. See the AutoCal's usage description in the Connectors section below.

Take a look at the example channel configurations.

D-STAR radio setup

  • Set the radio to single frequency mode.
  • If you want to use a reflector, set the URCALL on your radio to CQCQCQ. If you want to use a gateway, set the URCALL to the gateway's callsign and remote module. The remote module should be the last character of the URCALL.
  • Make sure you have registered your local module on the D-STAR gateway registration system. If you have a registration, you have probably registered the "space" local module. In this case set your openSPOT2's local module to a space (empty) character. You can check your D-STAR registration here.
  • You don't have to care about RPT1 and RPT2 settings.
  • Make a test call to the openSPOT2's built-in local echo service to test the connection between the transceiver and the openSPOT2 by setting the URCALL to .......E (7 spaces and an E, replace dots with spaces).

C4FM/Fusion radio setup

  • Set the radio to single frequency mode.
  • Use digital narrow (DN) mode. Voice wide (VW) mode does not support late entry.
  • If your radio has half deviation mode turned on, make sure you use the C4FM Half Deviation modem mode on the openSPOT2.
  • Make a test call to the openSPOT2's built-in local echo service to test the connection between the transceiver and the openSPOT2 by setting the DGID to 99 in your radio.
  • Run AutoCal in case you use the C4FM Half Deviation mode and there are voice quality issues. See the AutoCal's usage description in the Connectors section below.

NXDN radio setup

  • Set up a simplex channel (with the same RX and TX frequencies).
  • Set the channel's Radio Access Number (RAN) to the openSPOT2's RAN (by default it's 0, it can be changed on the Settings page, NXDN settings section).
  • Create a contact with private call to ID 9999, which is the openSPOT2's built-in local echo service. Make a call to this ID to test the connection between the transceiver and the openSPOT2.
  • Run AutoCal in case you have voice quality issues. See the AutoCal's usage description in the Connectors section below.

POCSAG pager setup

  • Make sure you set the your pager's receive frequency to the openSPOT2's POCSAG frequency, and that the baud rates match. Polarity should be normal. The openSPOT2's POCSAG frequency and other settings can be changed on the Settings page, POCSAG settings section.
  • Make sure you set the RIC(s) in your pager's configuration to the address(es) you want to receive messages on.
  • See the DAPNET Wiki for more information about POCSAG and DAPNET.
