Protocols: Rules for Working Together
Packet radio, like any communication, is only possible if all parties involved
(i.e., sender, receiver, and intermediate points on the route between them) agree
on the rules for organizing information and the rules for dealing with all steps of
the transmission. These rules are called “protocols,” or standards.
AX.25
The defacto standard protocol for amateur packet radio communication is
AX.25 (level 2, version 2). For details on AX.25, see the ARRL publication,
AX.25 Amateur Packet-Radio Link-Layer Protocol.
+ Hint: You can set the KAM’98 to use an earlier protocol, AX.25 (level 2, ver-
sion 1)
Alternatives to AX.25
TCP/IP and the KISS protocol : The TCP/IP (Transmission Control Proto-
col/Internet Protocol) suite of protocols require functionality not found in native
AX.25 packets, so Phil Karn KA9Q defined a protocol called KISS that imple-
ments TCP/IP functionality for amateur radio. For further information on KISS
see the KISS Mode section of the “Modes of Operation” chapter.
XKISS is an extension of the KISS protocol, defined by John Wiseman G8BPQ.
For further information on XKISS, see the XKISS Mode section of the “Modes
of Operation” chapter.
This concludes the introduction to multi-mode digital communication, including
non-packet and packet modes. The next chapter guides you through the steps of
installing your KAM’98.
