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.
