ok so ive been licensed for about 3 months now (technician, working toward general) and i keep hearing and seeing all these abbreviations and codes that i just dont understand. like QSL, QTH, QRM, QRN... there's so many of them and nobody really explained them to me in my licensing class, we just kind of touched on it briefly. and then theres all the other shorthand too like 73 and 88 and stuff like that. is there like a master list somewhere or does everyone just kind of pick it up over time? i feel like im missing half of every conversation on the bands because i dont know what people are saying. also saw someone write OM and YL the other day and had no idea what that was about either.

yeah you kind of just absorb most of it over time honestly, but the Q codes specifically have a pretty defined origin - they came from maritime and telegraph use way before ham radio was even a thing, which is why theres so many of them and they cover such weird specific situations. the ones you'll hear constantly are QTH (your location), QSL (confirming receipt or sending a confirmation card), QRM is interference from other stations, QRN is natural static noise, QSB is when your signal is fading in and out. QRZ is asking who's calling, you'll hear that a lot at the start of a QSO. the ARRL website actually has a pretty complete list if you just google arrl q codes, should come right up. OM just means old man, its just how guys refer to each other, doesnt matter how old you actually are, and YL is young lady, used for any female operator. 73 is the classic goodbye, means best regards basically, been used since the telegraph days too. 88 is love and kisses, usually only between close friends or couples in the hobby. once you get a few hundred contacts under your belt youll start using most of them without even thinking about it

so anyway i was in the exact same spot like two years ago when i first got my ticket and what helped me was just keeping a little cheat sheet next to the radio for a while. printed one off and taped it to the shelf. after a few weeks i barely needed it. the one that always tripped me up early on was QRP vs QRO - QRP is low power operation like 5 watts or less, QRO is cranking up the power. people talk about going QRP a lot in this hobby. also QSY means changing frequency which you hear all the time. theres some really obscure ones too that you almost never hear on voice, more of a CW thing, so dont stress about memorizing all 100 whatever of them right away
