so ive been listening to a lot of HF lately and everyone is throwing around all these QSL QRM QTH things and i kind of get what some of them mean from context but not really. like i know QSL has something to do with confirming a contact but then i see people say it like a question and also like a statement and it gets confusing fast.

and then theres all the other stuff people say that isnt even Q codes, like 73 and 88 and OM and YL and i have no idea where all this comes from. is there like a master list somewhere or is this just something you pick up over time? i tried googling it but half the results are just people selling QSL cards which isnt helpful

been licensed about 3 months, general class if that matters

yeah the Q codes go way back to telegraph days, they were basically a shorthand so operators could communicate across language barriers without having to type out full sentences. most of the common ones you'll hear on HF are pretty intuitive once you use them a few times. QTH is your location, QRM is interference from other stations, QRN is static/natural noise, QSB is fading signal, QRP means low power. QSL as a question means 'did you copy that?' and as a statement means 'i confirm' or sometimes just 'yes understood'.

the ARRL website has a decent reference page for the common ones, and honestly after a few months of actually getting on the air and making contacts it just clicks. the 73 thing means best regards, comes from old telegraph code too. 88 is love and kisses, usually only said to YL operators. OM is old man, friendly term for any male ham, YL is young lady but used for any female ham regardless of age. dont overthink it, just jump in and you'll pick it up way faster than reading lists

oh man i was so lost with this same stuff when i started. honestly what helped me most was just downloading one of those reference sheets and keeping it next to the radio. after a few weeks of actually using them it became second nature. QRZ is another big one, means 'who is calling me' but you hear people use it sort of as a general CQ sometimes which isnt really technically correct but whatever, everybody does it.

73 is one of those things that just feels weird to say out loud at first but you get used to it real quick
