Many radio amateurs now keep their log book on computers. Others prefer paper.
The content of the ham radio log book is relatively regulated, the layout – not so much. Here’s an example.
Sample ham radio log book:
The log book may have other columns that the radio amateur deems applicable, but in practice space is limited.
No matter on computer or paper, the log can be more than just a record of the mandatory attributes of radio communications. It can become a journal of your amateur experience.
Make it a habit to write down thoughts and comments, changes in station equipment, operator experience, and anything else that comes to your mind at the moment and may evoke fond memories years from now. Make your journal a reflection of your personal experience as a radio amateur.
Keep your journal neat, yet comprehensive and interesting.
