okay so ive been listening on HF for a few weeks now and i keep hearing and seeing all these weird codes like QRM and QSB and QRZ and honestly i have no idea what half of them mean. like i can figure out some from context but others just go right over my head. is there like a master list somewhere or do people just memorize these over time? also whats the deal with 73 and 88 i see those at the end of messages all the time. someone at my club mentioned 55 too but i cant find what that one means anywhere. feel like im missing half the conversation

yeah the Q codes can be overwhelming at first but honestly you only really need to know maybe a dozen or so for everyday operating and the rest you pick up over time. QRM is interference from other stations, QSB is signal fading, QRZ means 'who is calling me' and you hear that one constantly. QTH is your location, QSL means acknowledgment or confirming a contact, QRP is low power operation. 73 is just 'best regards' basically, its been around since like the telegraph days. 88 is 'love and kisses' so you mostly hear that between ops who know each other well. as for 55 i think thats 'best success' but honestly i almost never hear it on the air, might be more of a CW thing from back in the day. the ARRL has a full table of Q codes on their website and theres a few apps that let you look them up quick while youre listening. after a while it just becomes second nature, dont stress it too much early on.

oh man i remember being so confused by this exact same stuff when i started. the ones that tripped me up the most were QSK which is full break-in on CW and QRN which is natural static or noise as opposed to QRM which is like man-made interference. people use them kind of loosely in voice too which adds to the confusion. also dont forget stuff like 'de' which just means 'from' so like you'll hear 'W1XYZ de K9ABC' meaning K9ABC is calling W1XYZ. and ES just means 'and', TNX or TKS is thanks, OM is old man which is just how guys refer to each other, YL is young lady. its kind of its own little language really. just keep listening and it clicks eventually
