NXDN® radio: the radio access number (RAN) match in your radio and the
openSPOT4 (example: set it to the default 0). Make sure the talkgroup you
want to hear is in your NXDN® radio's contact list, or it is set as the TX
contact of the currently active channel.
You'll also hear silence in cross mode operation, when the incoming
transmission can't be transcoded to the current modem mode.
No one is hearing me on the network
Please read the Setting up your transceiver section.
Check where your radio is sending your call by looking at the Call log on the
openSPOT4's web interface. Make sure your radio is sending the call to the
desired talkgroup or reflector.
The openSPOT4's status LED should blink green when you press the PTT on
your radio:
If not, then make sure the openSPOT4 and your radio are on the same RX and
TX frequencies.
Make sure the openSPOT4's modem is set to the same mode as your radio, and
the following settings are set:
DMR radio: the color code (CC) match in your radio and the openSPOT4
(example: set it to the default 1).
C4FM radio:
The DGID is set to the same value both in your radio and the
openSPOT4 (example: set it to the default 0).
Make sure the Half Deviation setting is turned off in your transceiver,
and use plain C4FM modem mode on the openSPOT4. If there's no
such setting in your transceiver's menu, then you have to use C4FM
Half Deviation modem mode, and run C4FM Half Deviation AutoCal on
the openSPOT4 (or manually change the RX offset on the Modem page
for the lowest BER). Test the connection between your transceiver and
the openSPOT4 using the built-in local echo service.

If you are using a D-STAR® server, then make sure your callsign registration is
valid on this page. Also check if your registered callsign exactly match the
callsign you've set on your D-STAR® or C4FM radio. There should be no
suffixes. If you want to keep on using suffixes, then enable the Force source
callsign to D-STAR® network for cross mode calls setting on the Settings
page, D-STAR® settings section.
