Hi all, it does seem that 136 is quiet at the moment. 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.
