Packet RadioYou mean that stuff from the
80s?
● Digital communications mode using AX.25 - a derivative of X.25 data link protocol adapted for amateur radio use.
● Any station may be able to act as a digipeter - allowing the creation of both permanent and ad-hoc networks in a region.
● Common applications:○ Digipeter / Node○ Bulletin Board System○ Chat○ Winlink Gateway
