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.
