SKCC Skimmer is a program that helps find stations you have not yet worked in order to achieve various SKCC award levels (called GOALs) as well as stations that need you in order to achieve theirs (called TARGETs).
It runs on your local computer and uses data from five sources:
Real-time spots from the Reverse Beacon Network.
Your master ADI logfile of all SKCC contacts.
Member data from the skccgroup.com website.
The SKCC Sked Page.
The K7MJG RBN Retail Servers.
