Now there's talk of raising one's QRG on 160 to 1.9 mHz to have less
signal absorption while in pursuit of DX. But even with global
agreement, life would not be simple as the geomagnetic field varies in an
irregular
manner, making results variablet, with results depending on path.
Another geophysical factor, global in nature, could mprove DXing by its
very nature, without our intervention. Here, I refer to the flux of galactic
cosmic rays (GCR). They are of astrophysical origin, are essentially
uniform over the earth''s surface, and have a cycle like sunspots.
K9LA and I find 160 meter signal ducting varies with GCR and GCR are near
a minimum at present. The current GCR is easily obtained by going to the
Internet and calling up the Moscow neutron monitor. At preseht GCR is
about 3 units below background level. ,
When GCR is below background, DXing improves and when GCR is 10 to
20units below normal , DXing increases 10,000 km,, even almost 20, 000 km.
This is found in signal logs from DXers such as W7LR, K1ZM, SP5EWY, ZS4TX,
VK6VZ and NI6T.
These results are in recent issues of CQ Magazine and the Low Band
Monitor. In any event, if GCR is more than 10 units below normal, GO FOR IT
your results could be surprising/
