Buying a Hotspot
Simplex Hotspots is easy to set-up and use.
So we would recommend using/buying them.
Duplex Hotspots is not easy to set-up.
You must run MMDVMcal on Pi-Star and get the correct settings or they give issues.
Using more than one Hotspot on DMR
They must have different Frequencies and Color Codes.
Frequencies need to be 4 Meg or more apart so they do not interfere with each other
