[App_rpt-users] Autopatch on a simplex node?

[Bob Brown - NØEUH]

I woul dnot expect a simplex pathc to work unless some kind of sampleing is
done to see if there is any RX activity on the RF side as if you have a
patch up you will be in full duplex in oder for it to work properly ( ie
Phone call = Full Duplex) simplex wont work, as in you have no control of
the communications since your TX is up all the time.
