The WhereAVR is a small, lightweight, low-power, and low-cost APRS tracker with a full compliment of analog and digital I/O, as well as the ability to decode ax.25 packets. This allows for the reception of remote commands without the need for a “real” TNC. It is designed to hook directly to the speaker and microphone jacks of a handheld radio. One caveat, however, is that it currently doesn’t have a spiffy configuration utility.
