The Q Code came into being internationally in 1912 to overcome the language problems involved in communications by radio among ships and shore stations of all countries. The original list of 50 adopted by international agreement in London contain many which are still familiar to amateur operators: QRN, QRM, QSO; the traffic operator's QRK, QSY, and QRV - are now well past the half-century mark in continuous usage. QSL still has the official 1912 definition despite the changed informal usage in amateur parlance.
