Sven (DL7AD) has designed another miniature tracker board and we have soldered two PCBs last week. We have still two minor hardware issues that could be patched and the software needs to be re-written due to the new micro-controller. Current state is that on one board the GPS is unresponsive and on the other board the transmitter is broken. However that’s enough to work on the software for now. We’ll solder up some more boards next week and hopefully we’ll get a full working tracker soon.
