Abstract
The percentage deviation of citizen band transmitter channel frequencies from the standard channel frequencies is determined by counting the difference between the number of cycles in the transmitted and standard frequencies during a period of 0.37 second, the number counted being mathematically related to the percentage deviation by the same factor for all channel frequencies.
