I have received the kit just recently and I understand there are a few modes I can do, for example, adding two caps to the voltage regulator on the rardunio to prevent clicks, and one to improve mic clarity (perhaps a trimmer cap) as well as removing two caps to enable USB operation for digital modes. What I was considering was adding in a small solid state relay close to the board to enable me to easily switch from lsb to usb operation - adding or removing the caps using a dpdt relay. The relay would be controlled by a switch to the ardunio that would then toggle the relay and make the changes to the frequency calculation. Thoughts?
