What size would you like to see for an Metal Box enclosure??? I started drawing with a 6" wide x 6" depth x 3" height?? So the front and back panel is 3" high, the flat bottom is 6" wide by 6" in depth.?? If you made it a little bigger, maybe include that small QRP chinese antenna tuner???? Space for a PSK31 Audio interface?? Or another Arduino Nano board to generate the PSK31 transmit audio from a USB interface??? Lets here ideas for what size to make a box and why it should be that size??? When files can be uploaded again,? I will put my first rough draft CAD file? here:? /g/BITX20/files/Enclosures_Metal_or_Plastic/Metal_Box_files
