Pedestrian mobile APRS on the beach

Want to track something by radio independent of the mobile phone network? APRS could be handy. 

You basically need a 2 metre FM transceiver with VOX (voice operated transmit), a mobile phone with GPS, the APRSDroid app and an interface cable. It's best to get used to all this from home with a good antenna. 

Then once you've had success with that you could go for a wander to see if there are any receiving stations near enough to receive your signals. Sometimes there are, sometimes there aren't. My experiences, using a 5 watt handheld transceiver with small antenna, are in this video. 

After I made that video I did more APRS. That involved an outing with friends. We were in buses and walking through sometimes hilly forest. The longest distance a position from me was decoded was 100 km (from the bus) while from the handheld in scrub the distance was nearer to 4 or 5 km. 

This is the book for those returning to amateur radio. Available as a low-priced ebook or in paperback. More details including links to reader reviews here.
