General Information
Packet Radio is a form of digital communication between network nodes used by radio amateurs. The protocol used, AX.25, is derived from the X.25 protocol.
A basic Packet Radio setup consists of a dumb terminal (or a computer acting as a dumb terminal), a Terminal Node Controller (TNC), a radio tranciever and an antenna.
History
In the late 1970's a group of radio amateurs started to experiment with Packet Radio using a TNC developed by VE7APU Doug.
In 1980 ASCII transmissions was approved by Federal Communications Commission (FCC) for radio amateurs in USA. This approval started a lot of work by groups around in USA, including the Pacific Packet Radio Society (PPRS) in California, the Tucson Amateur Packet Radio Corporation (TAPR) in Arizona and the Amateur Radio Research and Development Corporation (AMRAD) in Washington, DC.
TAPR released their first TNC in kit form in 1983.
During 1980's and 1990's a lot of software for Bulletin Board Systems where written by W0RLI Hank, WA7MBL Jeff, F6FBB Jean-Paul and others.
Present
Today Packet Radio is mostly used for connecting to DX-clusters and to use APRS.
A number or NetRom™ Nodes are available via AMPRNet and Internet.
