APRS

M0PZT-7 APRSdroidThis page details how I use APRS to transmit my location when out and about on the bike (or walking).

If I’m out ‘n’ about and in a beaconing frame of mind, here’s the link to find me on APRS.fi as M0PZT-7.

I use APRSdroid which is a free application and works very well.  It supports a number of connection methods to an APRS Server – you can use a full-duplex TCP link which continuously retrieves APRS server traffic or opt for an HTTP/UDP “send-only” method.  The latter offers a significant reduction in mobile data used as well as extends the battery life.

I use the UDP connection which is set to beacon every minute which seems to work fine for bike speeds (5-15mph).  Due to the send-only connection, I won’t see any messages you send me.

For use at home, AGWTracker provides a GoogleMap interface that you can use with an APRS Server (you’ll need a passcode to transmit through it) or an external KISS TNC or soundcard interface (via AGW Packet Engine).
