“You’ve seen these printed on QSO cards, but what do they mean. I’m talking about grid squares, a unique method of geolocation that is popular with HF digital and VHF & UHF operators. When I say unique, I mean the grid square system has the ability to convey your location down to the precision of about 3.5 miles using only 6 characters. While that doesn’t sound very precise, it’s extremely useful and good enough for radio communications.
