[OZAPRS] QRM

Mon Nov 13 09:15:39 EST 2006

Gday Bob and all,

WICEN / Ham radio based emergency coms in South Australia for the most
part 
is centered primarily around major regional centers, with the local radio 
club for that center being the hub for this activity. E.g.. Port Lincoln,
Mt 
Gambier, The Riverland, The Barossa Valley. Most of these regions do 
currently contain there own Igate and digipeater(s)although not
necessarily 
controlled by the local radio club. In Adelaide, while there are several 
radio clubs that actively get involved with APRS operations, the main 
network coordination is done by one or two people. This makes network 
coordination through the whole of the state relatively easy. I believe
this 
is a similar situation with most of other states. WICEN in South Australia

has in fact utilized APRS extensively over the past few years for both 
vehicle tracking and message handling to great effect during community 
support events, Car Rally's and the like. Traffic levels are such that we 
can and have utilized the existing APRS infilstructure to run these 
excersizes. In our case APRS has proven to be an extremely valuable asset 
during these events, and therefore the APRS network and re-configuration 
should be done, keeping WICEN type activities as a primary focus.

Regards . Andrew .. VK5EX
