Capabilities - DV Development Group DV4mini D-STAR User Manual

Capabilities:
The DV4mini is a very small but also very capable USB Stick that can turn any
PC into a Hotspot for the digital modes D-STAR, DMR, C4FM and APCO P25.
It consists of a powerful 32 bit micro controller, a complete 70 cm/2 m
transceiver and a modulator/demodulator for GMSK and 4FSK and a USB
interface.
The DV4mini does not require an external power supply. It is powered
through the USB interface. Even older USB interfaces are sufficient. The
DV4mini is supplied together with a simple to use and comprehensive
software package. This allows linking with DCS, XRF and REF reflectors for
D-STAR as well as DMR, P25 and Fusion reflectors.
Many hams have a DV (digital voice) capable transceiver but cannot reach the
closest DV repeater. With the DV4mini it has become possible to create a
hotspot with minimal resources and thus get access to a DV network. It is
also possible to link C4FM repeaters with the reflector network.
The new DV4mini AMBE allows to talk to D-Star Reflectors or DMR Talkgroups
without a radio, just using a headset with microphone and speaker
connected to the PC. Fusion works with an external radio, the AMBE based
direct connection will be updated via software update later.
The UHF DV4mini can be set to any frequency between 420 MHz and 450
MHz. The VHF versions work on any frequency between 144 MHz and 148
MHz. However they also cover the 70cm band at a lower output power, so
they are dual band capable, but the output power on 70cm is lower than in
the UHF version.
