A report on interference caused by intermodulation products generated in or near land mobile transmitters

This report is a condensation of published papers combined with unpublished information on the subject of intermodulation products generation and interference created in or near land mobile transmitters. The following papers have been used in preparation of this report: Radio Report No. 50, "Investigation of Intermodulation Interference in the 100-108 Mc/S Mobile Radio - Telephone Service". Report prepared by Mr. C. H. Sturton assisted by Messrs. G. J.Campbell and B. T. Harnett of the New Zealand Post Office. Interference Due to Intermodulation Products UHF Maritime Service", Special Committee No. 36 of the RTCM. N. H. Shepherd, "BIDimensional Interference Analysis", Proceedings of the Third Conference on Radio Interference Reduction. Each of these papers provide excellent material that is useful as a continual reminder of the effects of interference and practical techniques for tracking down and reducing interference. A particular type of interference, intermodulation, is troublesome to locate since it can be generated in a variety of devices.
