The results of radio-echo observations of the Quadrantid meteor shower between 1964 and 1971 are presented. Radio magnitude distributions in the range |$+6\cdot05^\text{m}\,\text{to}\,+7\cdot55^\text{m}$| were determined as a function of solar longitude. A magnitude distribution index, s, of |$1\cdot 64\,\pm\,0\cdot 06$| was found. The position of the ascending node of the stream was found to be |$282\cdot{55}^{^{\circ} }\,\pm\,0\cdot 03^{^{\circ} }$| and the width of the shower (to half maximum activity) to be |$0\cdot{52}^{^{\circ} }\,\pm\,0\cdot{07}^{^{\circ} }$| Factors affecting the incident flux are discussed.
