Effects of Local and Skywave Interference on CB Radio Range

Leslie A. Berry

Abstract: The combined effects of local interference, skywave ("skip") interference, and radio noise on Citizens Band radio range are calculated. If the ionosphere reflectivity is normal or above normal during the next solar cycle, and CB use does not decrease, the operational range of CB users in cities of under 100,000 will be less than half its present value during daylight hours of nonsummer days for 3 years at the peak of the cycle. CB'ers in metropolitan areas with more than a million residents will probably not be bothered much by skip interference.
