| Why Packet Radio Could be, You are Missing Something Fun. Packet radio has been around since the mid-1960's, but was first seen on the amateur bands in 1978 through research done in Montreal, Canada in 1978. This was followed by the Vancouver Amateur Digital Communication Group (VADCG) development of a Terminal Node Controller (TNC), also known as the VADCG board, in 1980. This was then followed by TAPR (Tucson Amateur Packet Radio) with the creation of the TNC-1 in 1982 and then the TNC-2 in '84-'85. In 1985, the packet radio revolution ignited when TAPR sold over a thousand TNC-2 kits. The TNC-2 was what was needed to make this mode, that a few experimenters were playing with, into something that every amateur could enjoy... Read more |

Packet Radio: What? Why? How?
|
| Digital Communications Conference The ARRL and TAPR Digital Communications Conference is an international forum for radio amateurs to meet, publish their work, and present new ideas and techniques. Presenters and attendees will have the opportunity to exchange ideas and learn about recent hardware and software advances, theories, experimental results, and practical applications. Topics include, but are not limited to: Software defined radio (SDR), digital voice, digital satellite communications, Global Position System (GPS), precision timing, Automatic Position Reporting SystemŽ (APRS), short messaging (a mode of APRS), Digital Signal Processing (DSP), HF digital modes, Internet interoperability with amateur radio networks, spread spectrum, IEEE 802.11 and other Part 15 license-exempt systems adaptable for Amateur Radio, using TCP/IP networking over amateur radio, mesh and peer to peer wireless networking, emergency and Homeland Defense backup digital communications, using Linux in amateur radio, updates on AX.25 and other wireless networking protocols ...

Packet radio is a particular digital mode of Amateur
Radio ("Ham" Radio)
communications which corresponds to computer telecommunications. The
telephone modem is replaced by a "magic" box called a terminal node
controller (TNC); the telephone is replaced by an
amateur radio transceiver,
and the phone system is replaced by the "free" amateur radio waves. Packet
radio takes any data stream sent from a computer and sends that via radio to
another amateur radio station similarly equipped. Packet radio is so named
because it sends the data in small bursts, or packets. The current TNC standard grew from a discussion in October of 1981 at a
meeting of the Tucson Chapter of the IEEE Computer Society...
