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 openSPOT4'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
openSPOT4's voice announcements, which will be sent to TG9.
Create a contact with private call to ID 9999, which is the openSPOT4's
built-in local echo service. Make a call to this ID to test the connection
between the transceiver and the openSPOT4.
Run AutoCal in case you have voice quality issues. See the AutoCal's usage
description in the Connectors section below.

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,
and the local module on the openSPOT4 to D.
If you want to use a gateway, set the URCALL on your radio 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 openSPOT4's local module to a space (empty) character.

You don't have to care about RPT1 and RPT2 settings.
You can make a test call to the openSPOT4's built-in local echo service to
test the connection between the transceiver and the openSPOT4 by setting
the URCALL to .......E (7 spaces and an E, replace dots with spaces).
Take a look at the D-STAR® APRS® page if you want to forward your
transceiver's GPS position to the APRS® network.
If you use a Kenwood TH-D74A transceiver, then make sure the
Direct Reply
feature is turned off, as it basically causes automatic callsign routing, which
could cause one's transmission to not be heard on the used reflector.
