Subj : Ham Radio History (B) To : All From : Daryl Stout Date : Sun Apr 01 2018 10:37 am The Q Code 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 usages it is subjected to in amateur parlance. The QN signals for amateur net operation were introduced in the late 1930s by W1UE (now W4IA) to lighten the burdens of net control operators. --- SBBSecho 3.03-Win32 * Origin: RadioWxNet: The Thunderbolt BBS wx1der.dyndns.org (801:1/2) þ Synchronet þ Temple of Doom BBS - tod.eothnet.com .
