WAS stands for Worked All States. The Worked All States (WAS) award is earned by confirming QSOs with all 50 U.S States.
This award is anything but easy to get as you must have confirmed contacts with stations in all 50 US states either by card and/or LoTW . It is not unusual to have 49 states contacted and take years more to get that hard-to-pin-down 50th state, as was the case with me in chasing South Dakota for almost three years to complete my WAS award. The contacts listed in the following spreadsheet are the ones who sent me a card or have entered my call sign in their LoTW page. I updated each time I got a contact I needed. At the bottom of the page is a map of the 50 states with the different regions valid for ham operators.
I FINALLY ACQUIRED ALL MY 50 STATES FOR WAS ON JULY 27, 2014 !!!
