What is APRS ?
VK4GO -- JA1OGS
Packet radio has great potential
for passing large pieces of message traffic from one station to another.
However, with the internet growing by leaps and bounds a lot of folks,
including myself, seem to become disenchanted with packet. Then in 1993 I discovered
APRS! (Of course some of us discovered APRS before then but I digress…).
It was always difficult to apply packet to real time events. Especially
since these events seem to always be short lived. APRS can avoid this problem.
It is not limited to a connected network or its complexity. APRS permits
any number of stations to exchange data just like voice users do on a voice
net. Any user can send information and all stations receive it or transmitted
it. Secondly, APRS recognized one of the greatest real-time needs of any
special event or emergency. That is tracking of key assets! For instance…
Where is the event leader ?
Where are the emergency vehicles ?
What is the weather at various points in the
Where is a mobile\base amateur station ?
Where is the hurricane ?
Where is my car now (if stolen) ?
Where is a DX station?
Where is a Jota scout station ?
To answer these questions,
APRS is a full featured automatic vehicle location and status reporting system too.
All this is happening here in Australia & all over the world on the country allocated
APRS simplex frequency for is Australia 145.175MHz.
PS: There are a few HF APRS Gateway`s

Here in Far North Queensland (Atherton) we have a VHF APRS Digipeater VK4WAT-3 with live Igate feed from VK4GO
So if you have a old Packet,SSTV,PSK-31 modem
or a soundcard interface then you can monitor the APRS traffic flow VHF 1200bd Packet for activity.
The UI-View APRS software and maps are all free, but only for a hamradio
station with a Amateur Callsign
and no SWL or Commercial !.
