What you need to set up your own Network!!
#1 A Solidtronic or Radio Tone PC-Radio Interface Zello Gateway
#2 A computer with Windows XP, or 7
#3 A QYT 980 plus radio or HT
#4 the cables for the QYT radio or HT
#5 A couple of Handhelds or A extra radio to be able to talk to the network.
That's all there is to a simplex network over Zello. Network must be setup on a separate antenna.
