Although these codes are within the Aeronautical Code signals range (QAA–QNZ) and thus 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 forseen as long as we continued to use them only in amateur nets.”
I’ve never used these codes. I’ve never transmitted on the air. I have an American Technician class amateur radio license and am almost done studying for Canadian Basic qualification.
On Wikipedia source, linked above, there is a section: ARRL QN Signals For CW Net Use.
QNL as a CW abbreviation is listed as:
A notice to a named station that the frequency that the station is transmitting on is lower than the Net’s nominal frequency. c.f. QNH.
A notice to a named station that the frequency that the station is transmitting on is higher than the Net’s nominal frequency. c.f. QNL.
H seems to be representing High and L, Low.
I’ve been trying to decipher how the Q codes overall work. Here’s a good operational list of Q codes. QN subset not listed there. Only QR, QS and QT.
I’m assuming three letter codes are a function of telegraphy codes and have seen docs online placing the origin and popularity of various forms of telegraphy codes between (approx.) 1880’s – 1920’s.
It seems like there are just so many different overlapping sets of codes, decisions, agreements, organizing bodies, etc. It’s mind-boggling to try and untangle all of it.
I’ve only caught in the wild locally an amateur radio net (once) using a repeater I think about 2 hours drive away. I’m not sure how to find their schedules or frequencies. I am scanning with SDR, learning on my own. It’s like the internet but it’s not. It’s its own thing, for sure.
Excerpt from an ARRL document on QN Signs:
I’d like to learn more about nets. And untangle all these codes and abbreviations. It’s a compelling puzzle I’m engaging in for the sheer puzzle of it all.
Like this, what does it all mean, the Aeronautical Codes:
First defined in ICAO publication “Doc 6100-COM/504/1” in 1948 and in “ICAO Procedures for Air Navigation Services, Abbreviations and Codes (PAN a S-ABC)” [Doc8400-4] (4th edition 1989), the majority of the Q codes have slipped out of common use; for example today reports such as QAU (“I am about to jettison fuel”) and QAZ (“I am flying in a storm”) would be voice or computerized transmissions.
“Q” has no official meaning, but it is sometimes assigned with a word with mnemonic value, such as “Queen’s” (e.g. QFE = Queen’s Field Elevation), “Query”, “Question”, or “reQuest”.
I like this idea that “Q has no official meaning” but that it’s probably a question, query, inquiry or request of some kind.
QN is probably kind of like “Query Net” then I gues… though I haven’t found any document confirmation that in Q codes,
N = Net. (Labeling as Assumption for now)
QNL is used outside of radio to mean, occasionally, Quasi-natural language. References seem to abound for natural language programming, bots, conversational UI, etc. In some sense, that starts to feel similar to procedural words or prowords in radio:
I imagine QNL as a kind of clipped procedural language subset (superset?) used for specific kinds of transactional communication. Like the Q codes as a whole themselves, or radio prowords.
Something something, performative speech acts.
… the capacity of speech and communication not simply to communicate but rather to act or consummate an action, or to construct and perform an identity. A common example is the act of saying “I pronounce you man and wife” by a licensed minister before two people who are prepared to wed (or “I do” by one of those people upon being asked whether they take their partner in marriage). An umpire calling a strike, a judge pronouncing a verdict, or a union boss declaring a strike are all examples of performative speech.
