After many months of writing and revision, I have completed a new book that will help you communicate with air traffic control. Just out as a Kindle book at Amazon.com, Radio Mastery for VFR Pilots teaches you everything you need to know to talk to ATC.
From microphone technique to exactly what to say and how to say it, Radio Mastery for VFR Pilots will make you a skilled and competent communicator on the aircraft radio. Watch for an upcoming Radar Contact audio show with in-depth explanation of what this book can do for you. Until then, check out the book at Amazon.com. There is a 2-chapter excerpt that will give you a good idea of what to expect.
