Tuckerton Radio, NJ :

 

here a recording from 1984, mixing up WSC and SAG in cw (rb)

 

very friendly QSL by letter (rb, 1973)
verification letter from RCA's central office (Frank Schüttig, 1976)
interesting misprint in this QSL: they verify WSC instead of WSL... (Frank Schüttig, 1983)
here is a QSL card for WLO, when the station was operating together with KLB & WSC (Vladimir Rozhkov, 2000)
