Many friends who have been at this hobby a lot longer than I have worked some pretty famous people - King Hussein of Jordan, King Juan Carlos of Spain, Barry Goldwater.
I have never worked anyone famous per se, but I did get a chance to work the Arizona DX Association last night, which is celebrating Arizona's Centennial this week. Their call is K7UGA - the same used by Senator Barry Goldwater (SK). So when I heard them on 40 Meters tonight, I jumped at the chance.
It took a while for me to break the pileup; but I was successful. 5 Watts and the HF9V yielded me a response. I got the customary "599"; but they were truly a 599 here into New Jersey. One of the loudest signals on the band.
I will definitely send for a QSL card, as this may be the closest I ever get to working a "famous" Ham.
