Actually, I was the one who was confused! That's what I get for commenting late at night. Now I'm not sure what the derivation of "es" is. It's definitely used to mean "and", but I don't know why. In any case, thanks for the correction. Update: I just figured out where I got the mixed up Spanish connection! There is a Spanish word used as a Morse code abbreviation, and in fact it's used in every QSO. It's not "es", it's "de" which means "from" both in Spanish and on CW/Morse. So I had the right idea, wrong word. hi hi tks es 73 de WJ6V
