D-STAR PresentationOn Monday September 25th at 7pm, the DuPage Amateur Radio Club meeting will feature a presentation on D-STAR by Mark Thompson, WB9QZB. D-STAR is a digital protocol developed by the Japanese government and Japanese Amateur Radio League. Icom is the first manufacturer to manufacture D-STAR-compatible radios, although the protocol is open to anyone. D-STAR enables simultaneous digital voice and data transmission. At present, digital voice can be sent on 144, 440 & 1.2 GHz (4800 bps) concurrently with low speed asynchronous data (950 bps) in a narrow 6.25 KHz channel. High speed data (128 kbps) can be sent concurrently using TCP/IP on 1.2 GHz in a 130 KHz channel. D-STAR repeaters are connected via the Internet, which enables worldwide connections across the D-STAR network. Imagine having a broadband Internet connection via your mobile rig. Among the many possible applications, D-STAR promises enhanced emergency communication handling - the efficiency of simultaneous voice and data communications, as well as graphic and other large file transfers that are difficult or impossible with current packet technology. Mark, WB9QZB, will present the D-STAR system in detail, with an update on Icom technology, the radios currently available that support D-STAR, and what is in development. Mark has been actively involved for many years in local packet and digital radio activities, and has been featured on Hap Holly's RAIN Report. Please join us for an informative and entertaining evening, Monday, September 25th at 7:30 pm. The DuPage Amateur Radio Club membership meetings are held at the Holy Nativity Church located at the corner of 55th Street and Richmond Ave. in Clarendon Hills. The church is located about 1 mile east of Cass Ave. and ½ mile west of Rt. 83. Talk-ins will be on the 2-meter repeater. If you can't make the meeting visit the Illinois Digital Ham Yahoo Group
