Intermodulation interference becomes a serious factor in frequency usage when a block of consecutive channels is provided for a given type of radio service in a confined area. Formulas are presented which show the number of potentially interfering 3rd and 5th order intermodulation products that can be formed in a band of n consecutive channels. The probability of encountering interference when a number of operating channels are picked at random from this band of n channels is developed and the number of interference free operating channels that can be obtained by careful selection in this same band is also derived.
