Analog APRS does not work
Analog APRS currently only works if an analog
channel has been selected, the proper analog
APRS settings have been applied and an analog
iGate is within RF-coverage.
Make sure ‘Analog APRS’ or ‘DMR+Analog APRS’
is selected at the radio within the menu
‘Appendix → APRS → APRS Type’
Digital APRS does not work
Digital APRS only works if a digital channel has
been selected and the proper TalkGroup has
been assigned for the defined reporting
channel.
Make sure ‘DMR APRS’ or ‘DMR+Analog APRS’ is
selected at the radio within the menu
‘Appendix → APRS → APRS Type’
Cannot use the radio with
my local simplex hotspot
If it is pistar-based and single-hat, you need to
set both, ‘TX TS’ and ‘RX TS’ to ‘On’ within the
corresponding channel definitions of our CPS.
Radio reboots whenever I
press [PTT]
• Use an external antenna (suitable for the 2m
and 70cm band) connected via an antenna
cable to the radio.
• Use clip-on ferrites and place one of those on
the power cord, close to the radio body.
• Route the power cord and antenna cable
separate as far away from each other.
• Directly wire the radio to the car battery
without using the cigarette lighter socket.
Often the connection between a cigarette-
lighter plug and its socket causes such issue
whenever a higher current is drawn.
• Make sure the battery is fully charged and
provides sufficient voltage and power
If analog VFO-mode is
selected, transmitting is not
possible
Check the setting of RXOnly using the Channel-
Edit function as described in chapter 10.12
Channel Edit on page 112.
I do not understand those
CPS parameters such as RX
Time, TX Time, GCL
You are using an old version of our CPS. Please
update the radio firmware and install the
newest CPS. Both to be found in our support
area for the Radioddity DB25-D, DB40-D and
GD-88.
Cannot communicate with
the radio
Make sure the radio is turned on and the
supplied programming cable is plugged in on
both, the radio and the PC. Make sure the
driver is installed.
