ok so ive been listening to a lot of HF lately and people keep using all these weird abbreviations and i cant figure out half of them. like i get QSL means like a confirmation card or whatever but then i heard someone say QRM and QRN in the same sentence and i wasnt sure if those were the same thing or different. and then theres stuff like QSB and QRZ which i think i know but im not totally sure. is there like a master list somewhere or do people just kind of learn these over time? also heard someone say 73 at the end of every contact, is that a Q code too or something else entirely

73 is not a Q code, its just an old telegraph abbreviation that means best regards basically. its been around since like the 1800s and hams just kept using it. you also hear 88 sometimes which means love and kisses, mostly used between friends or with a YL on the air.

as for the Q codes, QRM is interference from other stations, like man made noise, whereas QRN is natural static, like from lightning storms and that kind of thing. QSB is when your signal is fading up and down, you know when someone sounds like theyre going in and out. QRZ just means whos calling me, you hear that a lot when someone is calling CQ and thinks they heard someone come back but wasnt sure who it was.

honestly the best way to learn them is just time on the air. after a while they become second nature and you dont even have to think about it. theres also the ARRL handbook which has a pretty complete list but youll mostly use maybe 20 or so of the common ones in everyday contacts.

yeah i was totally lost with this stuff when i started too. the ones i kept messing up were QRP and QRO because they sound similar but one means low power and the other is high power, which matters a lot if someone asks you to QRP during a contact lol. also QTH is your location which comes up constantly, and QSY means change frequency. once i figured those out most of the basic ragchew stuff started making sense. there are way more obscure ones that almost nobody uses anymore but the common ones you can probably pick up in a week or two just from listening
