What is a Tracker?
Using a RELAY to Digi
WIDE area Digipeaters
WIDE versus RELAY
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
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.
Packet rebroadcast to Wide

MCL
Packet rec’d by MCL (gate to UHF)Packet transmitted to NWS-ILXWX3 is in range of ILX so noWX# is needed.

APRS WX backbone detailsAPRS backbone is on 445.925 9600 baudThe GATE alias of MCL digipeats local APRS to the backboneThe Kantronics KPC-9612 GATEs using two transceiversThe 2 meter unit should only pick up local APRS stations.If it is too high, the delay waiting for dead air will slow WX ObjectsThe 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 NAMEDamage reports MUST include: YOURcall then the REAL AC PHONE# of the person knowing the location of the damage.
