C4Fm­fusion - DV Development Group DV4mini D-STAR User Manual

When you use TS2, you always transmit and receive on TG9 (local) This is
then routed by the DV4mini and the DMR Plus system into the selected
rooms.
So on TS2 you use CC1, TG9. Again, you need to program your radio
accordingly, and again do not forget to put TG9 into you receive group list!
There are multiple DMR networks available:
The DMR Plus network is developed and operated by the DV4 team, the
Brandmeister network by a team of Russian developers and the DMR-MARC
network by the Motorola Amateur Radio Club.
The DMR Plus network reflectors and the Brandmeister reflectors can be
selected in the expert settings.
DMR reflectors have numbers in the range of 4000 to 5000. Each region has
its own reflector, which can be selected in the DV4mini menu.
The DMR-MARC network can be selected by using the IPSC2 version of the
control center. Select the appropriate IPSC2 server as your DMR server and
you can connect to the Motorola TG on TS1 and to the DMR Plus TG on
timeslot 2.
C4FM­Fusion:
C4FM-FUsion is a system developed by YAESU. It is based like DMR on 4FSK,
and also transmits 4 frequencies with a total data rate of 9600 bits/s. It uses
the same AMBE+ Codec as DMR, but needs only 3600 bits/s. The extra bits
are used in D4FM-Fusion in a different way. They can be used for data
transfer (e.g. GPS) but also for additional error correction to make the speech
more stable during interference. There is also a mode for high speech quality
which uses all bits for speech only.
C4FM -Fusion reflectors are named FCS001 (Europe), FCS002 (USA), FCS003
(Canada)etc. All DV4minis connected to a reflector can hear each other. It is
very easy to connect a C4FM/Fusion repeate​ r to t​ h e FCS reflector system.
Just put a computer with a DV4mini next to the repeater and enter the
reverse RX/TX frequencies. We have seen remote feed operations of up to 2
miles line of sight.
