so ive been on HF for about three years now and SSB audio quality is something i keep going back and forth on. started out just running the stock mic on my 7300 and honestly it was fine, people could copy me, no complaints. then i fell down the rabbit hole of reading about mic gain and compression and TX equalizers and now im not sure if i made things better or worse.

the thing that bugs me is everyone online seems to obsess over flat response mics and processing chains and studio-grade this and that, but when i actually listen to most SSB contacts the bar is... not that high. like as long as youre not clipping and your audio is centered in the passband most people are happy. i run a heil PR-40 into the radio now with the icom eq set to bump the mids a bit and pull back some of the low end, and ive gotten good reports but im honestly not sure how much of that is the mic versus just having my gain set correctly finally.

curious what other people actually find makes the biggest difference in practice. is it the mic, the gain staging, compression, the eq, or just making sure you're not over-driving the finals and splattering all over the place. because i suspect the answer is mostly gain staging and everything else is kind of secondary

yeah gain staging is probably 80% of it honestly. ive heard guys with $300 mics sound like they're transmitting through a coffee can because their mic gain is cranked and the ALC is slamming constantly. the ALC indicator should barely be moving on normal speech peaks, if its pegged you're already in trouble regardless of what mic you're using.

the compression thing is a whole other rabbit hole. a little compression helps with readability especially on noisy bands, but ive heard people with so much compression its basically just a loud buzz, all the natural speech dynamics get destroyed and it actually becomes harder to copy not easier. the radio's built in compression on most modern rigs is fine if you dial it back to like 4-6 dB of actual compression, beyond that youre usually hurting yourself.

one thing i do think matters more than people admit is where your voice sits in the SSB passband. if you have a real bassy voice and youre not rolling off some of that low end, a lot of your energy is just sitting below where the radio is actually passing it efficiently. bumping presence around 2-3kHz does more for intelligibility than any mic swap ive ever done.

this is kind of what i figured when i got into HF but nobody told me, i spent like two months convinced i needed a better mic before someone on a net finally just said hey your gain is set way too high and i fixed it in five minutes. felt kind of dumb but also relieved because i wasnt about to spend another $200 on a mic

do you guys bother with a separate speech processor or is the built in stuff in modern radios good enough now. ive seen the W2IHY boxes and stuff like that and im not sure if thats overkill for just casual ragchewing and the occasional contest
