Hotspot

What is a Hotspot?

A hotspot is a device that allows digital voice mode radios to connect to the internet.  Once connected to the internet and routed through specialist servers, the operator can be connected to a reflector or 'room'.  Other operators connecting to the same reflector or room can then hold a QSO or net.  The use of hotspots and servers hosting reflectors allow cross mode DV QSOs worldwide.  Commonly, hotspots are made from a Raspberry Pi single board mini computer fitted with a MMDVM 'hat'.  The MMDVM is essentially a hardware and software solution that acts like a RF modem, allowing a radio to connect to a computer.  The Raspberry Pi computer, fitted with a MMDVM is often loaded with the Pi-Star software which allows the DV mode, frequency and target reflector to be configured amongst other settings.  Other makes of hotspot are available such as the Openspot Shark.  Hotspots are an excellent way to connect to other DV operators when you are not within range of a digital internet enabled repeater or public hotspot, often known as a node.
