In this chapter, our goal is to take three previous projects and combine them into one package, both in terms of hardware and software. The three projects are: 1) the PS2 keyboard keyer, 2) the CW decoder, and 3) the station clock/ID timer. You could easily integrate the capacitive keyer you built in Chapter 8, but we wanted to find a middle ground between the complexities of integration and narrative clarity. Three projects are enough complexity to illustrate the issues of integration, but simple enough to make the discussion clear. Also, many rigs already have a keyer integrated into them so there is less need to add that feature in this project.
One of the primary purposes of this chapter is to discuss some ...
