  1. Test of APRS trackingAdam’s Farm, Walpole, MA, USMay 26 and June 2 1, 2013

  2. Equipment • Kenwood TH-D72A • Diamond SRH77CA extended hand held antenna • Kenwood TM-D701A • AvMAP GEOSAT 6 APRS GPS unit • Garmin GPSMAP-60CSx

  3. Procedure • Walk the 2+ mile Adam’s Farm north loop • GPSMAP-60CSx taking track data • Kenwood TH-D72A sending position data • Two tests • No fillindigi support • Fillindigi support from Kenwood TM-D710A • Maximum airline distance from TM-D710A: about 0.7 miles

  4. Track in ARPSISCEno fill in digi

  5. Track in aprs.fino fillindigi

  6. APRSISCE with Topo and GPX overlay from GPSMAP-60CSx tack data

  7. APRS.fi track with D710A providing Fill in digipeating

  8. Comparison of GPS track, tack with no fill in digi, and track with fill in digi

  11. Conclusions • To provide robust tracking for foot traffic in the Walpole area fillindigis are recommended if not required • The Kenwood TM-D710A was determined to provide good fillindigi capability over an approximately 0.7 mile radius • It is recommended that an antenna better than the stock rubber antenna be used • APRSISCE can accept the GPX track data and provide a clean mapping of the foot mobile traffic overlaid over this GPX track data • This suggests that GPX tracks of critical off road environments should be captured prior to their need during an incident
