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.
6 meter QSO volumes versus Solar Flux- 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.
HF QSO volumes versus Solar Flux- 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.
(All Quarterly) Number of spots, average Solar Flux, and Distance (signal [short] path) in km- data obtained from NOAA, but some averages are low due to occasional server problems which caused incomplete downloads over the 2012-2016 time frame.
Note the decreasing average QSO distances as the solar cycle moves away from maximum.
Number of times reported as heard, by country(DX Entity)- how many spots reported contact with, or hearing, a station of this country/DX Entity. As of December, 2016.
Number of spots made by stations in this entity, by country(DX Entity)- 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.
