so ive been on SSB for a few years now and i keep hearing the same advice recycled over and over — speak across the mic not into it, compression is good, compression is bad, use a headset, dont use a headset. figured id start a thread where people share what has actually made a difference for them rather than just repeating stuff from a youtube video.

for me the single biggest improvement was getting my mic gain set properly. i was running it way too hot thinking more level equals better audio and all it was doing was making me sound like i was transmitting from inside a tin can. pulled it back until the ALC was barely kissing on voice peaks and suddenly i started getting reports that i actually sounded like a human being. second thing that helped was a decent desk mic with a bit of proximity effect — the stock hand mic on my 7300 was fine but nothing special.

also the TX bandwidth setting is something people sleep on. i had mine set to narrow because i thought that was polite and someone finally told me i sounded muffled. opened it up to about 2.8k and the difference was noticeable on both ends. yeah it takes a bit more spectrum but honestly on a clear frequency its not a big deal.

curious what other people have found — especially on the processing side. im not sure where i stand on compression still. feels like it helps in a pileup but im not convinced its doing much for actual audio quality day to day.

the ALC thing is huge and you're right that nobody talks about it enough. i spent probably six months wondering why i sounded mediocre and it was literally just mic gain too high. the ALC meter is not a VU meter, you're not supposed to be pegging it on every word. once i understood that everything clicked.

on compression — i use it but lightly. maybe 4-6dB on the speech processor and thats it. the temptation is to crank it because your audio sounds louder to you in the shack but what it sounds like on the other end with heavy compression is this kind of pumping distorted mess especially if theres any background noise getting in. a little goes a long way. if someone in a pileup tells me they can hear me fine im not touching anything.

one thing i havent seen mentioned is the equalizer if your radio has one. my 756 pro has a basic tx EQ and boosting just a little around 2-3kHz does more for intelligibility than anything else ive tried. voice cuts through noise way better without actually sounding processed.

honestly the advice about speaking across the mic changed everything for me when i first got into HF. i was treating it like a phone and talking directly into it and getting terrible reports. took me embarrasingly long to figure that one out.

the bandwidth thing you mentioned — yeah i had the same issue. i think a lot of people default to narrow because they read somewhere that its the considerate thing to do and then they sound like theyre calling from 1940. 2.4 to 2.8k is pretty much the sweet spot for me. anything wider and youre just adding noise floor without much benefit for speech.

not sure about the high end desk mics though, i use a pretty cheap dynamic and get decent reports so i wonder sometimes how much the mic itself matters vs just getting the settings right on the radio
