[App_rpt] Setting up a simplex node

That brings up another interesting point that I failed to mention in my
original posting. I am a little confused as to the definition of full
duplex. When I think full duplex, I think that of like a telephone
conversation where the caller and receiver can both talk at the same time.
How exactly does this work in App_rpt? I only have one radio to work with
with one simplex frequency, is this not intended for this type of setup?

That sounds like a more economical solution. Do you plan on having this
anytime soon?

One of the biggest things that attracted me to this project was openness. I
think echolink and IRLP are excellent systems, but too closed and
proprietary in nature which prohibits experimentation. I hope this project
goes far!
