You will need a DMR capable rig and access to a either a DMR repeater or a personal “hotspot”.

A hotspot is a very simple simplex access point usually consisting of a rRaspberry Pi equipped with an RF Digital Voice “hat” such as a DVMega or MMDVM. The hotspot will need Internet access, wifi or Ethernet,  to link your digital voice stream coming from the rIg as RF to the 4SQRP DMR Talk Group.

I have a DMR HT - an Anytone AT-D878UV.  I usually connect to the the 4SQRP Talk Group through my Raspberry Pi DMR “hotspot”.  I also Have used the AT-878 to go through a local DMR repeater to access the Talk Group . If you don’t have a repeater nearby, then you will need a “hoptspot”.

BridgeCom Systems has a variety of videos that will help you get started. They also sell DMR Rigs and hotspots, and even offer some “plug-n-play” kits that they will setup for you, but those are expensive. HRO also sells the rigs and more “do it yourself” hotspot kits.

Hope this helps get you started!
