Capability of this board and Software:
The DV4mini is a very small but also very capable USB Stick that can expand any
PC into a Hotspot for the D-STAR and DMR modes (C4FM Fusion is in
development).
It consists of a powerful 32 bit micro controller, a complete 70 cm transceiver and
a modulator/demodulator for GMSK and 4FSK (incl. Raised Cosine) and also a USB
interface.
The DV4mini does not require external power as it is powered via the USB
interface. The DV4mini is supplied together with a simple to use and
comprehensive software package. This allows linking with DCS, XRF and REF
refectors for D-STAR as well s DMR refectors.
Many hams have a DV 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 the DV network. We are talking about a
small board inside a USB stick with a SMA antenna socket.
System requirements:
These components are a prerequisite:
1. DV4mini USB stick
2. PC Software: DV4mini Control Panel
3. A DV capable radio (D-Star, DMR)
4. A PC with Windows XP, 7, 8.1, 10; Linux on a PC or an ARM computer like a
Raspberry, Banana Pi or Odroid.
5. Internet access
The DV4mini will be connected thru the USB interface with a PC or a single board
computer and the required software will be installed. After starting and setting up
the software one now has a Hotspot for the 70 cm band and can use it with a D-
STAR or DMR transceiver.
