so ive been listening to a lot of HF lately and i keep hearing and seeing all these weird codes like QRM, QSB, 73, 88, and a bunch of others and i honestly have no idea what half of them mean. i know 73 means like best wishes or whatever but thats about it. my elmer told me to just look them up but the lists i find online are like 50 pages long and half of them seem like nobody actually uses them anymore.

is there like a short list of the ones people actually use day to day? i feel like im missing half the conversation when im monitoring a net or just listening to ragchews. also whats the difference between QRM and QRN because i keep seeing both and i thought they were the same thing

oh man i remember being exactly where you are a couple years ago, it does get easier. okay so QRM and QRN are definitely not the same thing -- QRM is interference from other stations, like someone transmitting on or near your frequency, whereas QRN is natural static and noise, like lightning crashes or atmospheric stuff. easy way i remember it is QRM = man-made, QRN = nature.

the ones you'll actually hear constantly are QSB (signal fading), QSY (change frequency), QRZ (who is calling me), QTH (location), QRP (low power, though a lot of guys use that loosely), and QSL which just means confirmed or acknowledged. 73 is best regards and 88 is hugs and kisses, traditionally sent to or from women but honestly people use it however now. de means "from" so when you hear W1ABC de K5XYZ that's K5XYZ calling W1ABC. just lurk on some nets for a while and it really does click eventually

yeah what he said but also dont stress too much about memorizing all of them at once, some of the Q codes on those big official lists are super obscure maritime stuff from like a hundred years ago and you will literally never hear them on the air. the ones that come up in everyday HF contacts you can probably learn in a week just from listening. i'd say QRZ, QSL, QTH, QRM, QSB, and 73 will cover like 80% of what you encounter in a regular ragchew or net
