so ive been on HF for about two years now mostly doing digital modes but lately ive been getting more into SSB and i keep getting reports that my audio sounds muffled or like im talking through a sock or whatever. im running an IC-7300 into a heil headset, the PR40 boom mic element, and i thought that combo was supposed to be just plug and play basically.

ive messed with the TX bandwidth settings, tried narrowing it down to like 2.4kHz thinking that would help but honestly i cant tell much difference from my end obviously. someone on 40m last week told me i sounded like an AM station and i wasnt sure if that was a compliment or not. i think he meant i was too wide maybe.

what are people actually doing to dial in good SSB audio these days, like is there a standard set of adjustments on the 7300 that most folks run or is it all just personal preference and band conditions

the AM comment probably meant you were over-driving it tbh. the 7300 has a built in ALC meter and a lot of people just watch the TX power and ignore the ALC entirely which is a mistake. you want ALC barely moving, like just kissing the bottom of the scale. if its slamming around youre compressing the heck out of the audio and it gets that mushy processed sound.

also the mic gain and the bass rolloff settings in the menu are where i spent most of my time when i first set mine up. voice is mostly intelligibility in the 300hz to 2700hz range anyway so cutting below 300 actually cleans things up a lot, less boom, less room noise getting in. Heil elements tend to be pretty mid-forward already which works well for SSB but you can still mess it up with too much mic gain upstream. i run mine around 35-40 on the mic gain dial, nowhere near max. if you have a friend on the other end willing to give you honest reports on a sideband with low QRM thats really the only way to properly hear yourself

yeah i had the same issue when i switched from FM to HF, took me a while to figure out that SSB audio is just a completely different animal. one thing nobody told me was to make sure youre actually on the right sideband for the band youre on. i know that sounds obvious but i was running USB on 40m once for like 20 minutes before someone politely told me. doesnt affect audio quality directly but you sound absolutely terrible to everyone else lol

the bandwidth thing you mentioned is worth playing with more though. i ended up somewhere around 2.8kHz for general ragchewing and tighten it up if the band is crowded. also make sure youre not standing too close to the mic, i was practically eating mine and it was causing all kinds of low end buildup
