Some of this is undoubtedly due to the increased static noise levels discouraging listening. However my series of graphs of data from Brian CT1DRP suggest that, as we have moved down the solar cycle and the general Solar X-ray background level has declined, daytime skywave signals at distances of over 100km have decreased in strength. This decrease is anything up to 10dB. Best conditions for daytime qsos are now probably a day or two after a geomagnetic disturbance (Monday or Tuesday this week) when conditions will probably be back to "average" for a while. As before the best times are at around mid-day at the middle of the path. Cheers de Alan G3NYK
