APRSISCE/32 for Windows Mobile.

APRSISCE/32 is an Automatic Packet Reporting System (APRS) program, primarily intended for Windows and Windows Mobile (CE), although it will run on Linux and Mac OS under wine. Currently it has a large number of features, including enhanced messaging, announcement support via ANSRVR, and QRU for object query support.

APRSISCE/32 can run as a highly configurable Digipeater, with a TNC connected, and is able to command the TNC into and out KISS mode, and configure the TNC ports. It supports many of the APRS capable Radios. And automatically acts as an internet gateway with an internet connection (This can be turned off if required).

The Mapping system uses Open Street Map, and updates automatically over the internet, with tile sets cached for use without an internet connection. There is no need to download or configure the maps, although other maps systems can be configured.

Software updates are automatically detected and the option to download is in built.

PocketPacket iOS.

PocketPacket is an APRS client for your iPad/iPhone/iPod Touch.

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 or submit your station’s info from anywhere. Monitor moving objects, get real time weather reports directly from local stations and more. Now, with an iPhone/iPod Touch and PocketPacket, you can have a full-fledged picture of packet activity in a small, portable package – ideal for field work or the ham shack.
