We have radios in all of our aircraft. We simply prefer not to clutter the air waves, there is plenty of that already. Hand signals work fine for routine hook up and launch procedures. Towplanes make departure calls of course. Radio calls between tow plane and glider are not discouraged. The 21st century exists in America too.
