Another story of “HAM” origin: Another beautiful story has been discovered how this HAM was originated. At the beginning of 20th century in the year 1908 the word ham was first called in place of station CALL by some renowned ham operators of the then Radio Club.
The three operators of the club were Albert Hyman, Bob Almy, and Poogie Murray. At first they called their station as “Hyman-Almy-Murray”. To utter such a long name it was tiresome and called for a quick revision. Then they make it short cut with only two letters from their names.
As a result it came as “HYALMU”. But after a few years they discovered a Mexican ship in the name of “HYALMU” and a great confusion aroused among the ham operators. It needed immediate change of “HYALMU ” and then only one letter came for inclusion in the name of “HAM” for three initial letters for ham operators name. Thus the story ended with origination of “HAM “
