What can APRS do ?The Automatic Packet Reporting System was originally devised by Bob Bruninga (WB4APR) to transmit the position of mobile stations using a Mic Encoder - this device piggybacks a burst of packet data onto the end of a standard voice transmission. As the APRS protocol was extended, it allowed other information to be transmitted, such as:
APRS also posesses the unique ability for a user to passively monitior network activity, making it an ideal introduction to digital modes for Shortwave Listeners.
PC Weather StationYou could possibly extend your fixed APRS station, by interfacing it with a PC weather station - then by the addition of some software changes, make the weather data in your shack available via APRS to all local users.
Several implementations of Mobile APRS stations are available, both commercially (such as the TH-D7 from Kenwood) and as projects, discussed further within this document.
All of the above developments are supported by Roger Barker’s (G4IDE) UI-View program, which is available via the Internet. Although the unregistered 16-bit version is not limited in its functionality, please consider registering it. Not only does it represent a considerable effort on his part, but is probably the easiest to configure!
The registered version of UI-View also supports the gating of APRS data via the internet (IGATE). However, the exchange of APRS data via the internet requires a Note of Variation on the Holders’ Licence.
