Absolutely agree - wonderful resource and one that I have been using for many years.

WSPR however extends the propagation research toolbox further in not only covering 
bands from 2m to 160 and below but also gives the individual station instant feedback 
(in the database or world map plot) of where the signal is being heard using very weak 
signal detection techniques. As of today there are nearly 1.5 million spots in the 
database, 6000 of which were in the last 24hrs.
