To Use APRS from anywhere and from any device. Why does your APRS tracker only transmit once a minute?. Modem Options for Communicating with APRS World Products. APRS stations with two-way voice communication typically use the SSID 9. I needed some new trackers and thought about making some from scratch using SMD devices to keep them small and light, but this would mean first having to learn Eagle CAD in order to design the PCB and having to make a reflow oven so I decided to simply buy a couple of Tracksoar trackers from Mike. SSID 9 is not recommended for the StratoTrack since it is a one-way tracker only without voice communication capability. Systems connected to the Internet can send information on. Automatic Packet Reporting System (APRS) is an amateur radio-based system for real time digital communications of information of immediate value in the local area. As seen in the May 2015 QST!. Yet this is still the same basic design that allows hams to easily mock up the TNC on a breadboard, experiment with the open source firmware and software on their own, and even create their own custom cases. Here is some preliminary test to show you how to generate APRS (or AFSK in general) signal on Arduino UNO. The APRS packets are a combination of Base91 encoded position and custom telemetry data in the comment section of the packet. Mobile stations need an on-board GPS receiver. A Pecan is a cheap lightweight APRS position tracker designed especially for small ballons which may fly for monthes.
