Bill KC5SB has been using his “black beauty” µBITx on the FT8 digital mode and has already worked a station in Brazil with no problems. Bill has installed a fan because he spends a lot of time on digital modes. The display has been replaced with one with a blue background (goes better with black) and the unlabelled switch on the back is for the fan – high, off, low.
The case can be purchased here. It has, of course, been painted.
