Abstract
This report is aimed to investigate basic skills in mathematics necessary for learning radio engineering. The author extracts learning items in mathematics from the problem in radio engineering fundamentals which is one of the subjects of the national examination for Technical Radio Operator for On-the-Ground Services. From total results of the survey we find the frequently extracted learning items, which are regarded as the components of basic skills in mathematics for radio engineering. The survey results will be available in the improvement of class or teaching materials in radio engineering.
