so ive been listening on HF for a few weeks now and i keep hearing and seeing people use these weird three letter codes that start with Q and i honestly have no clue what half of them mean. like QSL, QRN, QSB, QRM... theres so many of them. i looked some up but then theres also all these other abbreviations people use in CW and even just in regular conversation on the bands that arent Q codes at all, like 73 or 88 or ES or whatever. is there like one place that lists all of this or do you just kind of pick it up over time? im a tech right now studying for general and nobody in my local club really explained this stuff, they just kind of assume you already know it all.

yeah this stuff can feel overwhelming at first but honestly you do just pick most of it up pretty quick once you start operating. the Q codes go way back to maritime radio, way before ham radio was even a thing, so theres a lot of them and not all of them get used regularly. the ones youll hear constantly are QSL which means confirmed or i acknowledge, QRM is interference from other stations, QRN is natural static like lightning crashes, QSB is fading which is super common on HF, QTH is your location, QRZ means whos calling me, and QRO or QRP are high power and low power respectively. the ARRL handbook has a full list in the back and so does the ARRL website if you just search for it. as for 73 thats just best regards, comes from old telegraph days. 88 means love and kisses and you mostly hear that between people who know each other. ES just means and in CW shorthand. once you get your general and start actually making contacts it really clicks fast, dont stress too much about memorizing it all upfront.

oh man i remember feeling exactly like this when i first started lol. i just kept a little cheat sheet next to my radio for like the first year honestly. QSY means change frequency which i kept forgetting. also people say things like OM which means old man but its not rude its just what you call another ham, and YL means young lady which is used for any female operator regardless of age. theres also stuff like DE which means from in CW, so when you hear a callsign DE another callsign thats just station one calling station two basically. the phonetic alphabet is another whole thing too but you probably already know that part. honestly just hang around on the bands and you'll start recognizing patterns pretty fast, thats how i learned most of it
