ok so ive been licensed for about 8 months now and i get on HF occasionally and i keep hearing and seeing people use all these abbreviations and Q codes and i only know like a handful of them. like QSL i know means acknowledged or like confirming the contact, and QTH is your location, but then people throw out stuff like QRM and QSB and QRN and i have to look them up every single time which kind of kills the flow of the conversation especially in CW where things are moving fast. is there a good way to actually learn these or do you just kind of absorb them over time? also whats the difference between using them in voice vs CW because i feel like on SSB sometimes people say them kind of weirdly like theyre showing off or something, i dont know. and then theres all the non-Q stuff like 73 and 88 and OM and YL and XYL and i only recently figured out what XYL meant lol. anyway just wondering how people got comfortable with all of this

honestly you just absorb them, thats really it. after a while QRM just means interference from other stations the same way a regular word would, you stop thinking about what the letters stand for. the ones that come up constantly on HF are QRM (interference from other signals), QRN (static/natural noise), QSB (fading, like your signal going up and down), QRZ (who is calling me, or sometimes used wrong as like 'is the frequency in use' which bugs some people), QRT means shutting down, QRX means standby, QTH location, QSL confirmed. those probably cover like 80% of what youll hear day to day.

the voice thing youre noticing is real, some guys do use them kind of performatively on phone. purists will tell you Q codes were designed for CW and written communication so using them on voice is technically redundant since you could just say the words, but its so ingrained in the hobby at this point nobody really cares. just dont let anyone make you feel weird about it either way.

73 is the one that threw me off for ages, i kept thinking it was some kind of code for something secret haha. its just best regards basically, like a friendly sign-off. 88 is love and kisses and youre really only supposed to use that one with YLs but people bend that rule. OM is old man which sounds rude but its just how hams refer to other male operators, totally normal. YL is young lady for any female operator regardless of age, and XYL is ex-young lady meaning basically a wife or partner.

i made a little cheat sheet when i was starting out and kept it next to the radio, that actually helped me a lot more than trying to memorize from a list. context is everything, if you hear QSB while somones signal is clearly fading it just clicks and you remember it. also ARRL has a decent reference but honestly the cheat sheet thing works better for me personaly
