Summary: While exposed to amateur radio at an early age, it was not until Mark Rosenberg, 4X1KS, got his first license and upgraded quickly within a few short months, in Memphis, Tennessee. In Memphis, Robert Barbee, W4AMI, became Mark’s ham radio mentor driving Mark to satellite excellence. Now in Israel, Mark is active in just about every on-air activity, as well as being the consummate fixer and home-brewer. 4X1KS is my QSO today.
