Hello. When a connection is established between two users, what kind of protocol is communication. Also, when two users are connected, if a user wants to connect to these two users, does the connection break, can a third person intervene in this connection?

VarAC uses the VARA protocol, created by EA7HVK, by using his software modem...VARA HF or VARA FM for VHF comms.
The mode is a one-to-one ARQ system, and only two stations can be in s QSO at a time.
VarAC adds many features, including the ability for a roundtable or net using broadcasts.
Normally communication starts by exchanging signal reports. Once that happens it's a good contact. Normally if it's the first time youve QSOed each other then exchange names and qth and LOC. If conditions are poor it doesn't matter 73 and put it in the log. 73 Damian
