  2. About “Shorty” • First licensed at age 18 in 1987 • Father KØCEY, Step-Mom KBØBAW, Cousin WDØFHK, Nephews KCØQIO & KCØKTP, Brother KCØQIN • KØKU President—1989-1991 • Started the NE KS ARC with WVØS for KU, KSU & Washburn Alumni interested in repeaters-Became NEKSUN • Operations Director of NEKSUN (NEKSARC & Sunflower Interlink) -Total of 14 & 19 digipeaters across Kansas & the midwest • President & FC for the Kansas Amateur Repeater Council • Coordinator for kcAPRS.org • Johnson County ARES Emergency Coordinator • Project Management Consultant for Sprint • Maintenance director for Heartland Tower • Private pilot wannabe

  3. Why We Are Here • What is APRS? • How did APRS originate? • What software should I use? • What Hardware should I use? • What do I need to know about the existing APRS network? • How can I get involved?

  4. What is APRS • Automatic Position Reporting System (previoulsy Automatic Packet Reporting System) • Packet communication protocol for sharing live data on a network in real time • Real time tactical communications and display system for emergencies and public service applications (APRS Spec)

  5. History • Invented by Bob Bruninga, WB4APR in 1992 • Devised to facilitate short haul, short duration data transfer – conventional packet was not suitable • GPS input came later

  6. History • APRS for DOS was the first program • MacAPRS & WinAPRS 1994 by Sproule brothers • UI-View—best support & popularity • Many other APRS apps since – runs on Windows 3.x, 9x, NT and XP, Mac, Linux, Palm, CE and DOS

  7. Packet Radio • History • AX.25 protocol was approved by ARRL in 1984 • Came from X.25 protocol (the A is for Amateur) • Primary difference from X.25 is allowance for call signs and for unconnected packets

  8. Packet Radio • In ‘packet’ radio, qso’s are always between ‘connected’ stations • Several qso’s can take place simultaneously on the same frequency • Packet qso’s may be digipeated by specific stations

  9. How is APRS different from Packet Radio? • Communication is ‘one to many’ • Uses generic digipeating with standard aliases • Supports intelligent digipeating to reduce network flooding • Uses UI frames for messaging, bulletins and announcements • Provides maps and other features

  10. How APRS uses Packets • Uses the same AX.25 protocol but only a part of it • Uses Unnumbered Information (UI) frames exclusively • Always runs in unconnected mode • Frames are transmitted without expecting any response • Reception is not guaranteed

  11. Frequencies • VHF 144.39 • 1200 baud • HF 30M 10.15151 LSB • 300 baud • Satellite • ISS Downlink 145.800, uplink 145.990 • PCsat simplex 145.828 • 1200 baud

  14. Balloon Chasing • What do you need 2B a good Balloon Chaser? • Detailed Map • You WILL be in unfamiliar territory. • Visibility of balloon location & height • Auto display of your station & balloon • Needs to display in one place, so you can concentrate on keeping up with the balloon! • Field Observations • Need to see temperature & wind all around • See other chasers • Keep the convoy from getting lost

Emergency Operations • What do you need 2B a good Emergency Operator? • INCLUDING SAR • Detailed Map • May be deployed to unfamiliar territory. • Latest WX info from the NWS • Need to see Watches & Warnings • Radar • Field Observations • Need to see temperature & wind all around • See other spotters • Need to know where all field units are deployed • Objects • Indicate damage or roadblocks on a map for all to see • List of Shelter Locations • Short Messaging • Communicate more confidential info to EOC or field units • Email capability • Need to be able to send short messages to internet users

  16. Special Events • What do you need 2B a good Event Specialist? • Detailed Map • May be deployed to unfamiliar territory • Aid Stations need to be on the map • Event Route needs to be shown • Hazards or Medical support locations need to be displayed • Latest WX info from the NWS • Need to see Watches & Warnings • Radar • Field Observations • Need to see temperature & wind all around • See other specialists • Need to know where all field units are deployed • Objects • Show first & Last Runner • Show event officials • Show Safety units • Show medical units & rovers
