  8. What is a Tracker?

  9. Using a RELAY to Digi

  10. WIDE area Digipeaters

  11. RELAY’s are mostly home stations The are used to fill in areas with no WIDE coverage WIDE’s are permament Digis They have good coverage WIDE versus RELAY Generally RELAY’s should be the first callsign in the path, such as RELAY,WIDE,WIDE Relays are used to fill in the gaps. Wides do most of the work.

  12. Packet sent to Relay,Wide,MCL Packet received by Relay Packet rebroadcast to Wide Packet received by 4 Wide Digi’s Packet rec’d by MCL (gate to UHF) Packet transmitted to NWS-ILX WX3 is in range of ILX so no WX# is needed. MCL Operation of the NWS-ILX Backbone Wide Packet Transmitted to Wide, MCL Relay Wide Wide Wide ILX

  13. APRS WX backbone details • APRS backbone is on 445.925 9600 baud • The GATE alias of MCL digipeats local APRS to the backbone • The Kantronics KPC-9612 GATEs using two transceivers • The 2 meter unit should only pick up local APRS stations. • If it is too high, the delay waiting for dead air will slow WX Objects • The PATH to ILX ends with “,MCL” + “your WX# UHF 9600 path” • The # in WX# for the backbone is the tens of miles radius from ILX. • WX Objects are entered by one emergency powered base in each county or net. Having the internet would be a plus. That station should be familiar twith his county roads and be able to enter that on his version of APRS while he is listening to the local voice weather net. • WX Objects REMARKS MUST include: YOURcall Confirmed (or Reported) by REAL NAME • Damage reports MUST include: YOURcall then the REAL AC PHONE# of the person knowing the location of the damage.
