Unfortunately there has been an assembly error on the v 0.6 complete kit. Wrong component has been installed for D5 and D6 on the RF board. Although same component is used for D1 as well, it is not critical to change it. But D5/D6 are part of the SWR/PWR bridge and it is important to install the correct component. Please check if your RF board looks like that:
And if yes, please drop me a mail with your postal address. I will send you the correct replacement parts, free of charge.
I am sorry for the trouble, it was my error causing wrong BOM file sent to the factory.
