1000 Miles Per Watt
This is probably the most fun awards I've earned. The 1KPW award is managed by the QRP ARCI and is awarded to stations that communicate with another station such that the total power and total distance come out to be at least 1000 miles per watt (used). I earned mine with a CW QSO with an Italian station using my Elecraft KX1 at 2.2 watts. The math came out to be 1680 miles per watt. Fantastic!
