Stage By Stage Construction
This method is very secure as you know the particular stage is working after you have constructed and tested it,there is no cause to worry later.
BITX CONSTRUCTION PLAN: By Leonard
After examining them, I decided to make an "exploded" layout drawing using a section-by-section approach to the assembly and testing. I will function test each section as it is assembled. This will almost insure that the board will function when everything is completed. I already had an head start on the project as this would be the 3rd Bitx I had built. I already knew what the signals should look like in each stage.
