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 openSPOT4.
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 DGID to 99 in your radio. Don't forget to set the DGID back to AUTO (or
ALL or 00, depending what's available on your radio) after you've done with
the local echo test.
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.
Take a look at the Wires-X® button usage description and the C4FM/Fusion®
APRS® page if you want to forward your transceiver's GPS position to the
APRS® network.
