520	|a"This report describes a project to monitor, automatically, the signal levels of 10 channels in the 150-175 MHz land mobile service band for 24 hours a day 5 days a week. Equipment was assembled and operated to gain experience which would assist in specifying a future operational system, and from this experience, channel usage statistics were calculated for each channel for each hour of the day during April and May 1972. The results showed that, for a 6 hour "busy-period" between 1000-1600 hours, 5 minutes per hour was sufficient monitoring time for a reasonable estimate of each hour's operation and a sampling rate of at least one sample per second per channel was necessary to ensure the interception of the shortest transmission"--Abstract.
