Very basic beginners question about how VarAC is intended to be run...
Should one take care not to send anything while the other stations is expected to be sending something, or can both stations write and send texts same time and software will take care that "traffic collisions" are avoided so that all messages fly in both directions simultaneously?
So only one side should be sending at a time as in "Simplex" or does not matter?
Keep in mind that VARA is a ARQ mode, it will handshake and take care of this it self.
