PocketPacket is a full-featured APRS client with a built-in TNC. The "Automatic Position Reporting System" is a packet communication protocol used by amateur radio operators (hams) around the world, to report position, status, station capabilities, weather or other information in real time. Packets can also be used for broadcasting announcements or one-to-one messaging. PocketPacket incorporates a software-based TNC, allowing you to directly capture and visualize, or encode and transmit 1200 baud packets (AFSK modulation) using a VHF radio transceiver. With PocketPacket you can also get and send packets over the Internet, by selecting one of the available Tier 2 servers of the global APRS-IS network. Incoming data is presented on a map, as most packets define some object, with a specific symbol and location. By selecting a symbol, you can view the latest information sent for the corresponding object, as well as the raw packets that produced it. All available objects are also shown in a list, which allows you to search for the ones you are looking for. Messages and bulletins are shown in a separate set of screens, structured like an e-mail client. With PocketPacket you can follow the status of the APRS network, submit your station's info, monitor moving objects, get real time weather reports directly from local stations and more. PocketPacket is ideal for field work or the ham shack. 73 de SV9OAN
