Free Radio Network gives more reach to mobile / portable wireless users. With the FRN Client program you are able to create a gateway that connects a communication channel of a local mobile / portable radio to the network. To do this the program must run in "Gateway" mode.
If you do not have the ability to set up your own gateway and there is no other gateway in your area, then you can use the program in "PC User" mode (PC only) to talk to FRN users on the network .
