FNpack is a specialized Packet software designed to allow a net control type of messaging system. It has been chosen by Greene County ARES (Missouri) for emergency typed traffic between stations set up in community hospitals. You can find it here: www.w1fn.org/fnpack/index.html
I don’t have much experience with FNpack. I have used it a few times. It’s not as elegant as the previous mentioned programs. If you are a GC ARES member however, we urge you to download the program get comfortable with it.
