Topband: Sudden Ionospheric Disturbances

[ZR]

Ive been running comparisons between European BCB down in the 200KHz region, 
some NDB's, Experimenters band at 500KHz, AM BCB, and 160M for many years. 
The 500KHz section only for a few years.

While there has been some correlation there is often just the opposite and 
with enough ambiguity thrown in to completely confuse the issue. Others 
living further South and West might find a completely different set of 
results. Ive noticed many times over the decades how as little as 25 miles 
can affect 160 when disturbances are involved since there is a lot of 160 
activity in New England and after awhile you know who can do what.

The following website has some interesting information that may help us to 
figure out what goes on in topband propagation
It seems to be reasonable to expect that VLF conditions relate to MF 
conditions
