List of local amateur radio repeaters Repeaters

Automatic Packet Reporting System (APRS)

The Automatic Packet Reporting System is used to transmit short messages between local amateurs. It's most common use is to transmit location data, whereby GPS co-ordinates of the amateur station are transmitted. These can then be plotted on a computer map, allowing people to see the location of other amateurs around them. The short radio packets are sent on a common frequency (in North America usually 144.390 mhz). They are picked up by repeaters and rebroadcast. Some repeaters can also gate the packets onto the internet. You can see APRS info mapped at APRS.fi. Note that APRS.fi also maps the AIS system, which is the Automatic Identification System used for ships. All commercial ships must transmit identification info that includes the name of the ship, its size, heading, speed, etc. This info is transmitted on 161.975 and 162.025 mhz, but uses a different encoding system from APRS, and therefore requires a different receiver. Again, there are receivers in some areas (including Hamilton) that pick up this info and gate it to the internet.

More info on APRS can be found at APRS.org and APRS Wikipedia page
