Raspberry Pi based AllStar Link microHUB assembled by G7RPG.
The microHUB is a self contained lightweight hotspot providing access to AllStar and the Echolink networks via its internal low power UHF FM transceiver with approximately 100 meters range.
Remote control is by DTMF commands or through a simple web application on a smartphone, tablet or PC.
The microHUB connects to the internet via its integrated WiFi adaptor and is supplied completely preconfigured ready to use.
The microHUB has its own internal switching power supply and can be powered from 9 - 24V DC via a standard
DC ( 2.1x5.5mm) connector, a DC cable is provided for connection to the shack 13.8V supply.
