Operating modes:
Digital ham radio repeaters are connected via reflectors. This allows for
worldwide connections from one repeater to another.
The DV4mini makes its own connection to this reflector network and gets
access to all connected ham radio repeaters.
The hotspot includes a low power 70 cm/2 m transceiver. All voice
communications on the connected reflector will be transmitted by the
hotspot on 70 cm/2 m and one can listen and transmit with a digital radio.
A hotspot is an ideal solution if there is no good access to a digital repeater
because you are inside a building, you are too far away or you are on
vacation.
You use your own call sign for the hotspot. Reduce your transmit power to a
point where you still able to cover your living area for a reliable
communication.
Hardware:
Use the hotspot mode to enter the frequency to be utilized for DV operation.
(check your band plan).
Your transceiver will be set up for Simplex use - RX and TX on the same
frequency.
The DV4mini gets the 5 Volt operating power from the USB interface. On
some computers the voltage could be too low (we measured below 4.5 V on
some). In this case you can’t operate. Then the best solution would be to use
a USB adapter with its own power supply.
