Andrew ,
Yes I have APRS Ports setup on each machine. I have a AGW Port and a APRS-IS Port as a rule.
After reinstating the Config it asks me for my IS Passcode which I have to Enter along with some other things like callsigns for each Port.
I have the Persist setting set but for now and the settings stayed between restats on the program.
I have given up on raster Maps because reinstating them is just too much work every time.
