This radar log book is divided into two parts. Part 1 is intended for recording the occasions on which the set is used, and the conditions existing at the time. Part 2 is for recording results obtained on various targets, for comparison and future guidance.
A few pages of PPI blanks are included so that important radar pictures or phenomena may be permanently recorded. Also included is an explanation of the use of the log, and notes on radar phenomena
