QN Signals
The QN Signals are Morse code operating signals that were introduced for Amateur radio net operation in 1939 on the Michigan QMN Net to lighten the burdens of net control operators. Originally created by a committee of the Detroit Amateur Radio Association led by Ralph Thetreat, W8FX. Ev Battey W1UE, then ARRL assistant communications manager, later printed them in QST.
The QN Signals are defined in ARRL document FSD-218 and listed in the ARRL Operating Manual.
Although these codes are within the Aeronautical Code signals range and th us conflict with official international Q signals beginning with QN, the ARRL informally queried FCC's legal branch about the conflict. The opinion then of the FCC was that "no difficulty was as long as we continued to use them only in amateur nets."ARRL QN Signals For CW Net Use
