RECEPTION OF WWV AND WWVH IN NORTHERN CANADA
Abstract
UI T-DAY DIURNAL, S ASONAL, AND LATITUDE VARIATIONS IN RECEPTION QUALITY OF WWV and WWVH transmissions on six frequencies from 2.5 to 25.0 mc at five northern Canadian stations between 45 degrees and 75 degrees N latitude are given. Solar, propagation-mode, and auroral effects on these transmissions are considered. The investigation shows that the ori ntation of transmission path with respect to auroral zone affects reception quality on long paths (WWVH), and reception improves going northward. It appears that a tilt mode of propagation on long path is possible at times when sunrise occurs simultaneously near the two end points of the path. On magnetically quiet days, WWV (15.0 mc) reception has been possible for all hours of the day regardless of season during sunpot maximum of 1957-1958. (Author)
