yeah there's no FCC rule that says you have to use NATO phonetics specifically, at least not for amateur radio. it's different for aviation and some other services but for ham you're just required to identify, not HOW you identify as long as its intelligible. that said NATO became standard for a reason — if you're working someone with a heavy accent or in a pile up the standardized words are way less ambiguous. "sugar" vs "sierra" doesnt matter on a quiet local repeater but try working DX on HF with weird phonetics and people will start asking you to repeat. the guys who use their own phonetics on local FM are fine for that context but id learn the NATO ones properly first just so its muscle memory when you actually need it

Are you using the same gain settings? HackRF's AGC behavior can cause unnecessary CPU spikes if not properly configured. Also worth checking if you're hitting USB3 vs USB2 bandwidth limitations - that can affect processing overhead significantly.

I was in the same boat last year! One thing that helped me was bookmarking a propagation site and checking it before getting on the air. Focus on 20m, 17m, and 15m during the day with those numbers. Don't get too hung up on perfect conditions - I've worked great DX when the numbers weren't ideal.

Thanks for sharing the hard data! This confirms what I've been telling newer hams. Countries with small amateur populations are less likely to have bureaus, which means the more sought-after QSLs often can't go via bureau and need direct mail - it costs much more but it's needed for the prized cards.

Don't forget the low-noise preamp - critical for EME! Install a low noise preamplifier with 0.5-0.8 dB NF at the antenna input point. Also use quality coax like LMR-400. Your 17-element should give you around 14-15 dBi gain which puts you in the game, especially with digital modes doing the heavy lifting.

yeah what KD5XYZ said, plus make sure you know your phonetics and can copy down messages reasonably well. i remember my first drill i was so focused on not screwing up the radio part that i completely botched writing down a simple health and welfare message lol. also might want to review the ICS forms if your group uses them, though they'll probably go over that stuff during the training portion
