This book was originally done as a project to enable me to use my BC-221-AK without having to keep thumbing through the original calibration charts risking damage to the original book. All the pages I have made are in Micro$oft Excel and are editable by you to put in your own BC-221's calibration dial settings.

The completed book I made is also shown here as a PDF file, this prints out on to A5 size paper and is only slightly larger than the original book, but infinatley better in respect of not damaging the original calibration book and you can print a new calibration book out for your own BC-221 when ever you need one.
