so ive been listening on HF for a few weeks now and i keep hearing and seeing all these weird codes and shorthand that i just dont understand. like people say things like QSL and QRZ and QRM and i know QSL is like... confirming contact? but im not totally sure even about that. and then on PSK31 and in contest logs i see stuff like 73 and 88 and DE and all kinds of other stuff that nobody really explains anywhere.

is there a good way to learn all of this or do you just kind of pick it up over time? i looked up a Q code list online but there were like hundreds of them and i dont know which ones actually get used vs which ones are just historical. feels overwhelming honestly

yeah it feels like a lot at first but honestly you only really need to know maybe a dozen or so to get by day to day. QSL is yeah, confirmation or acknowledgement - like "I copy that" or also the physical cards people send. QRZ is "who is calling me" so when someone says QRZ? they're asking who just called. QRM is interference from other stations, QRN is natural noise like static from thunderstorms. QSB is fading, which you'll notice a lot on 20m when signals just drift up and down.

the ones you'll hear constantly are QTH (your location), QSO (a contact or conversation), QRP if someone's running low power, and QRT means you're shutting down or leaving. 73 is just "best regards" - it's old telegraph shorthand. 88 is love and kisses which people mostly use with close friends or significant others on the air. DE just means "from" in CW and digital modes, so like W1AW DE K1XYZ means K1XYZ is calling W1AW.

honestly just get on the air and ask people. most hams are happy to explain stuff and thats kind of how you really learn it, not from memorizing a list

dont stress about memorizing the whole Q code list, thats like 150 years old and most of them were for maritime or commercial use anyway. the ones that actually come up in regular ham use are maybe 20 at most. i'd been licensed for two years before i even heard QRK used on the air and i had to look it up (it's signal readability, fwiw).

one thing that helped me was just hanging around on a local net for a while and writing stuff down when i didn't recognize it. context usually makes it pretty obvious. like if someone says "QRM from that station on the adjacent frequency" you know it means interference even if you didn't know the code before
