I just want to confirm that version 3 works.? It functions the same as previous versions, but draws LM386 pin 1 down to ground rather than up to 12V, due to concerns about current in the LM386.? I substituted a 2N3904 for the 2N2222, otherwise identical with the schematic here:
/g/BITX20/attachment/30784/0/BITX_40%20PTT%20CLICKS%20V3.png I had a question about the board and how it was built.? It is called manhattan-style, with raised pads punched from copper clad board with a hole punch, glued to the copper clad board used as the ground plane.
