the position of vehicles, the status of weather, radio direction finding and much much more.
all you need is a vhf-radio, a gps-receiver and a tnc. kenwood has started to build some radios that have a
built-in tnc, some of these models are the th-d7, tm-d700 and tm-d710. now almost all other companies like
yaesu, alinco, ... have a handheld or mobile radio that is aprs-ready. if you have one of these radios you only
need a gps-unit and you are all set to start in aprs.
your aprs-signal will be received by a local aprs-digipeater and resent on the same frequency. in europe the
frequency is 144.800 mhz. there are a lot of aprs-gateways active which send the received data to the internet.
so everyone can track your movements in real-time. it is also possible to send short messages to other hams.
mobile and portable stations should use WIDE1-1,WIDE2-2 and fixed stations WIDE2-2 as their aprs-path. in
regions with good aprs-infrastructure you should consider reducing your path to avoid unnecessary traffic.
paths like RELAY,WIDE,TRACE7-7 are not good and only occupy the frequency ... and such settings are making
it harder for portable, qrp and mobile stations to get into the aprs-network. also think about how often your beacon
is transmitted. for fixed station it's not necessary to transmit the aprs-beacon every 5 minutes, it's enough to send
it every 30 minutes. for mobile and portable stations an intervall of 2 minutes should be appropriate.
