OK, co workers uncle was a ham, radio man in the military, passed on. He never knew his call. Was from Chicago. So be a 9 call. This was in the 60's and 70's. His name Was Ronald M Then (long since went SK)
Anyone with those old call sign book, kindly see if they can find a call associated with that name? I suspect it will be a W9XXX, but that is just a guess.
Thanks.
Rick
