I received a few requests for a bit more detail on various things that I do for flights. Here's a procedural of preparing one of my trackers for flight.
I go ahead and remove the JST connectors I used for testing of the solar and supercap inputs.
After soldering on the counterpoise, I tape it pretty heavily. That's all the tape near the top. The reason is that I don't want the counterpoise wire twisting and wrapping around the GPS chip antenna a the top of the board. That would end up causing problems. In Wisp2, I'll think about better ways position the chip antenna and counterpoise to reduce the amount of tape needed for this.
Finally, I attach the antenna wire (right spool). It's soldered onto the antenna pad, and a bunch of tape strain-relief is applied.
To weigh it, take my little clip mount and put it on my scale, and turn it on. That sets the tare weight of my scale to the weight of the base. I then clip on the tracker, as shown, and the tubes (which are laying on the table in this pic). The resulting weight on my scale is the tracker plus the tubes. I weighed the tubes prior to assembly, so I can subtract that weight, and I have the exact weight of the tracker plus dipole and tether.
