List of changes:

Version 2.1.EE: changes of the toggle switch (SW1) on the printed circuit board, now the contacts of the case are soldered to the GND area.
Version 2.0.EE: the RF line width has been recalculated using Saturn PCB Design V7.08. At the moment, the resistance of the RF line is close to 50 Ohms.
