Nintendo Switch controller fix, and Lora measurements

One moment playing with LoRa. Next, a Nintendo Switch controller to fixed.

Side buttons or whatever you call them didn’t work anymore, so I replaced the flex PCB.

LoRa Antenna measurements

Using my NanoVNA and a RF test Kit I learned something about measuring antenna.

Below a measurement of a unknown antenna, ITs off, I need to shorten the metal spring inside.
