[Aavso-sid-list] VLF and Decametric SID comparisons?

[Thomas Ashcraft]

I was going through some of my old webpages and came across a page of 
SIDs that I captured at 18.7 MHz.  I know that most people here on this 
list observe at VLF but I wonder if anyone has ever made a comparison 
between SIDs received at VLF and decametric frequencies?

Here are some sample 18.7 MHz SIDs:
