ok so ive been licensed for about 3 months now and i keep hearing people say things like QSL and QRZ and QTH and honestly i have no idea what half of them mean or when youre supposed to use them. i looked up a list online but there are like hundreds of them and i dont know which ones actually matter vs which ones are just old maritime stuff nobody uses anymore. also people on the air sometimes use abbreviations that arent even Q codes like 73 and 88 and stuff like that. is there like a short list of the ones i actually need to know for everyday HF and VHF operating? i feel kinda lost when im listening to a pile up and people are throwing all this shorthand around like everyone just knows it automatically

yeah the full list is overwhelming, dont even worry about memorizing all of it. in day to day operating you really only bump into maybe a dozen or so regularly. QSL means confirmed or acknowledged, QRZ is who is calling me, QTH is location, QRM is interference from other stations, QSB is fading signal, QRN is static/natural noise, QSY means change frequency, QRP is low power, and QRO is high power. thats honestly most of what youll hear on a typical HF contact.

73 just means best regards, been that way since the telegraph days. 88 is hugs and kisses, mostly used between close friends on the air. some guys also say things like FB which stands for fine business meaning like great or well done, and OM which is old man — just a friendly term for any male ham regardless of age. it sounds weird at first but you get used to it fast. just listen for a few weeks and itll all click naturally, i promise you wont need to drill flashcards or anything like that

honestly the ones that tripped me up the most early on were QRM vs QRN — i kept mixing them up. QRM is interference from other stations, like someone transmitting on your frequency or nearby, and QRN is the natural static stuff like from thunderstorms or whatever. took me embarassingly long to get those straight lol. also QSK is full break-in CW mode which you probably wont need right away but youll hear it eventually
