so ive been listening on HF for maybe 3 weeks now and i keep seeing people type things like QSL and QTH and QRZ in the logbooks and on websites and i honestly have no idea what half of them mean. i looked some up but then theres like a hundred of them and some of them seem to mean different things depending on context? like QRM vs QRN i still get those mixed up. also people on the air say things really fast and abbreviate everything so even when i do try to listen in on a QSO... see i just used one, i think... i cant follow whats happening. is there like a go-to reference people use or did you all just kind of absorb this stuff over time

yeah the Q codes thing is one of those things that feels overwhelming at first but honestly you only end up using maybe a dozen of them regularly. QTH is your location, QSL means confirmed or acknowledged, QRZ is basically "who's calling" or someone asking if the frequency is in use, QRM is interference from other stations and QRN is natural static like from lightning or whatever. QSO is just a contact or conversation, which you already picked up on. the rest of them you'll just kind of absorb as you hear them. theres an ARRL reference page that lists them all but honestly dont try to memorize the whole thing, just look them up as they come up and after a few months of being on the air it clicks. also 73 isnt a Q code but everyone uses it and it just means best regards, kind of a goodbye

QRN vs QRM tripped me up forever too lol. the way i finally remembered it was N for natural, M for man-made. static from a thunderstorm = QRN, some guy running a plasma tv near the repeater = QRM. thats it, thats the whole trick. also worth knowing QRP means low power operation, youll see that a lot in threads here
