so ive been licensed for about 4 months now and still working on getting comfortable on HF. my elmer always told me to use phonetics when giving my callsign especially on SSB but i was on a net last week and someone just said their call letters straight without phonetics and nobody seemed to care. then another guy used like... not the standard ones? he said something like "Nancy" for N instead of November and "Tommy" for T. is that actually allowed or is there some rule about using the official NATO ones? i dont want to be that guy who does it wrong but also i dont want to be overly formal if nobody else is. its a little confusing honestly

yeah there's no hard rule forcing you to use strictly NATO phonetics in the US at least. the FCC regs just say you gotta ID with your callsign, they don't specify HOW you say the letters. NATO phonetics are just the standard everyone agreed on so theres less confusion, like November vs Nancy both work but if you're in a pileup with bad conditions November is gonna cut through better because everyone already knows to listen for it. the non-standard ones trip people up sometimes because you're sitting there waiting for the next letter and your brain is trying to figure out if Tommy is the T or the start of a different word. i'd just stick with NATO until it becomes second nature, then you can break the rules if you want lol

honestly when i first got on HF i was SO worried about phonetics and within like a month it just clicked. the main time it actually matters is weak signal stuff or when theres a lot of QRM and someone really needs to copy your call correctly. on a local net on a clear frequency it probably doesnt matter much. but i still always use NATO just out of habit now. also worth noting some DX operators get confused by non-standard phonetics if english isnt their first language because they learned the NATO ones and thats it, so there is a practical reason beyond just rules
