After nearly 15 years, and almost 54 Million Grids mapped in close to 300M uploaded QSOs, this site will be decommisioned on June 18, 2025!

My time, energy and resources are focussed on other things at this time. Note: there are other logging tools that now include similar functionality.
I hope you've enjoyed this site! 73 - Johan, WG7J
