so ive been licensed for about 3 months now and i keep hearing people throw around all these abbreviations and Q codes and half the time i have no idea what they're saying. like i know QTH is location and QSL is like confirming a contact but then someone said QRM to me the other day and i just kind of said yeah thanks and moved on because i didnt want to seem like i had no idea what was happening

is there like a good way to learn these or do you just kind of pick them up over time. also whats the difference between QRM and QRN because i see both of those a lot. and what does 73 mean, someone explained it once but i forgot. sorry if this is a dumb question im still figuring everything out

not a dumb question at all, everybody goes through this. QRM is interference from other stations, like another signal stepping on yours, whereas QRN is natural static and noise, think lightning crashes or atmospheric stuff. easy way i remember it is QRM = man-made, QRN = nature. and 73 just means best regards, its been used since the telegraph days actually, way before radio. there's a whole list of what they called Phillips codes back then and 73 was one that stuck around.

as for learning them, honestly just print out a Q code reference sheet and keep it next to your radio for a while. you'll stop needing it faster than you think. the ones that come up constantly on HF are QRM, QRN, QSB which is signal fading, QRZ which is who is calling me, and QSY meaning change frequency. those five probably cover like 80 percent of what you'll hear day to day. the rest you just absorb gradually.

yeah QRZ trips people up because it sounds like it should mean something else lol. when someone says QRZ? they're asking who's calling them, but i've seen new folks think it means the website which i mean fair enough since that's where most people look up callsigns now anyway. also dont forget 88 which means love and kisses, you'll hear that sometimes especially if someone's talking to their spouse on the repeater, its a whole thing. 73 and 88 show up at the end of contacts all the time once you know what to listen for
