The Arctic Tracker project isnt dead. It has just been “resting” for a while (sorry, we have been busy with many things). However, a second version is underway, based on the ESP-32 module and experiences from the first round. I will describe this in the next post.
It is some time ago now, but here are some pictures of the resulting tracker prototype (based on a Teensy 3.1 and an ESP-8266). It worked, it had a display, but the PA module didn’t work as expected. Probably due to instabilities and feedback through the antenna switching network. In the new design this is fixed.
Stay tuned..
