so ive been licensed about 4 months now and still a bit fuzzy on when youre supposed to use the NATO phonetics vs just saying the letter normally. like i get that on HF when conditions are rough you want to spell things out phonetically but what about on 2m repeaters when everyones coming in clear as a bell? i feel kinda silly saying "Kilo Foxtrot Seven Alpha Bravo Charlie" every single time i identify when nobody is having trouble understanding me. is there like an actual rule about this or is it just kind of a best practice thing that people do out of habit

there's no FCC rule that says you have to use phonetics, you just have to ID with your callsign every 10 minutes and at the end. how you say it is up to you. on a local repeater where everyone knows your voice half the guys just rattle off their call sign like normal speech and nobody cares. phonetics really shine when conditions are marginal or youre working someone who doesn't speak english as a first language, or honestly any DX situation where your call could get garbled. i've heard guys on 40m get their callsign completely mangled because they didn't go phonetic and the other station logged them wrong. so use your judgment basically, if it's a scratchy contact or you're working someone far away, go phonetic. casual ragchew on the local 2m machine, not really necessary.

yeah what he said but i'll also add that some guys kind of make up their own phonetics instead of NATO and it drives me absolutely crazy lol. had a guy last week saying stuff like "N for Nancy, K for kitchen" and i just... why. stick to the standard ones because if you ever do any nets or emcomm activations people expect the NATO alphabet and anything else just causes confusion. not saying you're doing that but worth mentioning for anyone reading this
