Navin R. Johnson said it best…
If you’re wondering why I care so much,I wrote a lot of Chapter 4, the new Digital Basics chapter. Some came from the old Basic Electronics chapter, but I hope to have it completely rewritten for the 2011 edition. I also have 3 projects in Chapter 24. So, it’s pretty cool. Besides,when you contribute to the Handbook you get your copy for free… and every ham NEEDS at least one ARRL Handbook around.
