so ive been licensed for a few months now and i get on the air occasionally but honestly half the time i dont know what people are saying. like someone will say QSY or QRM and i sort of nod along but i dont actually know what it means. and its not just Q codes either, people say things like 73 or 88 or FB and i have to just guess from context. is there like a good reference for all this or do people just kind of pick it up over time? i feel like im missing half the conversation every time i key up. also someone told me to QRX and i just sat there not knowing if i should respond or not which was kind of embarrassing

haha dont worry about it, everyone goes through this. the Q codes came from old telegraph days and theres actually a pretty long official list but in practice you only really hear maybe a dozen or so on a regular basis. QSY means change frequency, QRM is interference from other stations, QRN is natural static like lightning crashes, QSB is fading signal, QRP means low power, QRX means stand by or wait, and QRZ is asking whos calling. QTH is your location. thats probably 90% of what youll hear in casual HF ragchews. 73 just means best regards, its been used forever. 88 is hugs and kisses, usually between certain operators. FB means fine business which is basically just saying something is great or good copy. honestly after a few months it just becomes second nature you dont even think about it. just keep listening and itll click

yeah the QRX thing gets people, it literally means please wait i will call you again in X minutes, so basically just means hold on. i got confused by QRO and QRP for the longest time too. QRP is low power like 5 watts or less and QRO means crank it up, high power. theres also QSL which you probably already know means confirm or acknowledge, like a receipt basically, and thats where QSL cards come from. one thing i'll add is that in contests people shorten even more and it gets wild, you'll hear stuff fly by super fast and it takes a while to parse it. ARRL has a decent list on their site if you want to bookmark something
