What you will need

MMDVM

WIRES-X radio

Internet


A MMDVM (Multi Mode Digital Voice Modem) is a link from your wires-x capable radio to a room on the wires-x system – allowing you to speak to other hams.

This can be particularly useful when out and about as you don’t need to link your radio in PDN mode to a laptop

The Software (Operating System) runs on a small computer called a raspberry pi

There are different models and sizes from the small pi zero to the full sized pi – these can be used as a desktop PC giving them more then enough processing power and features to run pi-star

Well for around £70 (fully assembled) you can get a small MMDVM JumboSpot; running pi-star

Mini MMDVM Hotspot with 0.96″ OLED screen

Where to get an MMDVM

You can buy there from many places – including our shop.
