Aprs Information

APRS provides situational awareness to all operators of everything that is going on in his local area, whether it be Weather reporting, traveler info, Direction Finding, objects pointing to ECHOlink and IRLP, or Traffic reporting and emergency response. All of this while providing not only instantaneous operator-to-operator keyboard messaging capability for special events, but also an always-on Voice Alert backchannel between mobiles in simplex range. There is even an APRS interface to the WinLINK system called APRSlink, so that mobiles can send and receive Email without needing a PC. Think of APRS as a signalling channel to reveal ALL amateur radio resources and live activities that are in range of the operator at any instant in time. UBIQUITOUS OPERATIONS: APRS must work everywhere to be a true resource to the mobile ham radio operator. In North America, 144.39 MHz is dedicated throughout the continent. In Europe, use 144.80 and in Australia use 145.175 MHz.. National operating rules were standardized in the 2004 time frame under the New-N Paradigm to eliminate obsolete and inefficient routing. Now, only a 2 hop WIDE2-2 path is recommended in all areasthough mobiles can use the special WIDE1-1,WIDE2-1 two-hop path that takes advantage of nearby WIDE1-1 fill-in digipeaters. See the high density areas in the map to the right. Further, the APRS channel is a resource to inform everyone of nearby ham resources in range. Please see the Local Info Initiative.
