To: List for people interested in the D Star repeaters ; Sent: Monday, October 5, 2009 6:59:54 AM Subject: AX.25 Packet Retired from the 2009 MTCM Project - All Data now D-Star DD Mode After three years of flawless D-Star operation in 2007-2009, the Amateur Radio team supporting the Medtronic Twin Cities Marathon has officially retired AX.25 packet from the effort. "We've used D-Star DD Mode now for three years, and we're no longer afraid of the technology" said one of the leaders of the project. The five Icom D-Star RP-1D access points installed on Twin Cities building rooftops have been 100% reliable, including at the unusually warm 2007 race, where more than 50 runners were sent to area hospitals. The group uses Linux routers with DNAT co-located with the RP-1Ds to allow dozens of
area Amateur Operators to have high speed access to applications in a
central data trailer without use of the Internet. "The low data rate, complexity of the character mode interface, and user training issues we have had with packet have put it on the back burner" said Erik Westgard, NY9D.? "Again this year we can sit any available operators or even community volunteers in front of our web based missing runner application and they can be helping family members immediately." One objective for the 2010 team is to start phasing in D-STAR digital voice, who also allows the concurrent use of low speed data. Erik Westgard, NY9D 10/5/2009 |
