24 Hike Across Maryland Using an HT to report ALL 100 runners! (40 miles) Location/time of over 100 runners reported by APRS messages.Hams (youth < 23) agreed it was as easy as Texting or Tweeting.
25 What is APRS?APRS = Automatic Packet Reporting System (not position tracking!)APRS since late 1980's was for local tactical digital communications, situational awareness and TWO-WAY information exchangeMessages + maps for OBJECTS – everyone sees the same situation and Network ConnectivityA single Reference Resource for all HAM activitiesNot just GPS Vehicle Tracking!

35 What is APRS all about? (Humans communicating INFO with Humans) Immediate local digital and graphical information exchange between all participants in a local area or event. This includes:Positions of all stations and objectsStatus of all stationsMessages, Bulletins and AnnouncementsWeather data and telemetryDF bearings and signal strengths for quick transmitter huntingRF Connectivity plots of all stationsLocal OBJECTS on a common map display for all usersLocal Freqs, IRLP, ECHOlink, Winlink, Nets, Meetings, events, HamfestsTypical applications are:Routine local awareness of all ham radio events and assets around youMarathons, races, events and public serviceSearch and rescueFamily communications and tracking and one-line sMobile-to-mobile global text messagingWeather data exchange and displayEfficient multi-user Satellite communications
36 Scope of APRS Over 40,000 users worldwide. RELAYS every mi called “digipeaters.”All linked by home station IgatesGlobal links by Amateur SatellitesThousands of Weather stationsTelemetry and data everywhereBut, only 2% of local ham radio users…(a side show)…
37 APRS = Events, Info and Objects! Dayton Hamvention
38 APRS MisConceptions! See aprs.org/APRS-tactical.html That APRS is just Vehicle Tracking instead of a Real-Time Information Distribution System.That APRS is dependent on GPS for its value (GPS is not needed. See Objects).Failure to use the APRS built-in Mile-Marks for tracking all other non-APRS mobiles.Using APRS clients that only do maps and ignored too many of the APRS fundamentals.Ignored the fundamental Decay Algorithm to accelerate new data, and decay old data!Failure to understand the importance of OBJECTS: . See Objects 101 and OperationsFailure to use real-time messaging: . See Messages 101 and Message OperationsFailure to implement the original APRS Centralized Common Bulletin Board concept.Not understanding the APRS operator’s role as a Data Input (Objects, Bulletins and Messages)Not using the D7 and D700 as data entry and clipboard display units at field events.Too much focus on Large Screen Displays –vs- Individual Operator displays for events.Failure to display APRS symbols with all their attributes and colors without clicking themFailure to manage the network by adjusting the local digipeater for the situation at hand.Not realizing the importance of Voice Operating frequencies in APRS.

Now we have a Hardware Version!

58 APRS Voice Alert! *(For all mobiles!)Voice Alert is effectively 3rd Radio channel for the D7 and D700 APRS radiosBy setting the APRS Band A to CTSS-100,but keeping the volume turned up:You wont hear any packets on *But you will hear a voice call using PL-100 onAnd you will hear* an occasional Ping packet if another D700 comes in line-of-site to you, like a proximity radar alerting you to local presence.Great for long haul traveling and meeting other APRS users.

60 The New-N Paradigm 2004 Factor of 3 to 5 improvement! APRS Generic Paths evolved over 13 years and the presence of many old legacy formats and procedures were really bogging down the network making it saturated and unreliable in busy areas.In 2005 all old paths were declared obsolete (RELAY & WIDE) and the entire APRS system in the US was then focused only on the WIDEn-N type of generic paths with small values of N.WIDEn-N goes N hops outward in all directions.N=2 in most areas colored on next slide50% of repeaters still not configured right!
