This is a catalog of results obtained by analyzing the database of DXCluster spots (Sep. 2012 through Nov. 2016). They are pdf's - if you have Adobe Acrobat installed, they will display in your browser.

- SF data obtained from NOAA, but some averages are low due to occasional server problems which caused incomplete downloads over the 2012-2016 time frame.

- how many spots reported contact with, or hearing, a station of this country/DX Entity. As of December, 2016. 

- how many spots have been entered by stations in this country/DX Entity. As of December, 2016. 



These histograms show how often different frequencies within each band have been reported in a spot. Note: many of the reports consist of multiple pages.
