What is W3EAX?
By now you are probably wondering what the heck "W3EAX" means. It's our call letters (or more accurately, "callsign," as there's a number in there).
Amateur Radio Station W3EAX
Like WMUC, it was assigned by a government agency (the Department of Commerce, in particular, as W3EAX predates even the Federal Communications Commission, or FCC, having been assigned to us no later than early 1934). and is in a worldwide-standard format for callsigns as defined by the International Telecommunications Union (ITU) in Geneva, Switzerland. It is our "license-plate number" that uniquely identifies us to the world (and beyond, see below).W3EAX is a station in the amateur radio service. This is a special world-wide communications service, defined by international treaty, devoted to technical experimentation, public-service, and promoting international goodwill.
