The results of radio-echo observations of the Quadrantid meteor shower between 1964 and 1971 are presented. Radio magnitude distributions in the range + 6.05m to + 7.55m were determined as a function of solar longitude. A magnitude distribution index, S, of I 64 i was found. The position of the ascending node of the stream was found to be z8 0.030 and the width of the shower (to half maximum activity) to be o.5z0 o'o7 . Factors affecting the incident flux are discussed.
