I downloaded this ham radio related software program called truetty which offers several amateur radio digital modes including RTTY, Packet Radio and other modes including PSK-31 using Phase Shaft Keying with a baud rate of 31.25 and the transmitted band width is only 31 Hertz on HF. The audio from the receiver is fed into the computer sound card via mic or line input. (No TNC or Modem required.) PSK-31 works very well in crowded band conditions and works quite well, even at lower RF output ... Views: 5,520 |

Packet radio is a form of digital data transmission used to link computers. The most common use of PKT is in amateur radio, to construct wireless computer networks. Its name is a reference to the use of packet switching between network nodes, which allows multiple virtual circuits to coexist on a single radio channel. Packet radio networks use the AX.25 data link layer protocol, derived from the X.25 protocol suite and adapted for amateur radio use. en.wikipedia.org ka1fsb.home.att.net... Views: 439 |

On this date the first known three-network transmission took place among SRI International, Menlo Park and the University of Southern California via London, England. The networks involved were the ARPANET, the Bay Area packet radio network, and the Atlantic packet satellite network. This inter-network transmission among three dissimlar networks is generally regarded as the first true Internet connection. It was ... Views: 7,000 |
