So ive been on HF for about two years now mostly digital modes but lately been spending more time on phone and honestly the reports i'm getting are all over the place. some guys say i sound great others say i sound muffled or like im in a barrel and i cant figure out what the difference is. im running an IC-7300 with the stock mic, no EQ set on the radio, just basically default settings out of the box. i did read somewhere that the bass response on the stock mic is too heavy for SSB and you want to roll off below like 300hz or so but i havent touched any of that yet. also i notice when band conditions get rough my audio is the first thing to fall apart — like guys running 100w like me will still punch through better somehow. is it really just mic EQ or is there more to it? compression? ALC? i feel like theres a whole rabbit hole here i havent even started going down

yeah the stock mic thing is real, the HM-219 or whatever ships with the 7300 isnt bad but the proximity effect and the way most people hold it or position it makes the low end really bloated on SSB. what youll want to do is get into the menu and play with the TX tone settings — the 7300 has a decent parametric EQ built in and if you cut somewhere around 200-300hz and maybe add a tiny bit of presence around 2-2.5khz your audio will tighten up a lot. also check your ALC meter when youre transmitting, if its pinning constantly youre overdriving the finals and that adds distortion before any EQ even matters. a lot of guys set their mic gain way too high thinking louder = better but on SSB it really isnt, you want the ALC just barely moving into the yellow on peaks, not slammed. compression is worth looking into too but id get the basic gain staging right first before adding a compressor into the chain or youll just compress a bad signal into a consistently bad signal

the barrel sound is almost always too much low end yeah. i switched to an Heil PR-781 a while back and the difference was pretty immediate, those mics are voiced for comms use so they naturally cut a lot of the stuff below 300hz that just muddies up a sideband signal anyway. not saying you need to buy a new mic right now but if youre ever at a hamfest and see one for cheap its worth grabbing. one other thing — whats your RF power set to? sometimes guys are running reduced power for whatever reason and that can make marginal audio way more noticeable, like if conditions are already bad there isnt enough signal to noise for people to fill in the gaps. also make sure youre not too far off mic, SSB really rewards being like 2-3 inches away not a foot like people do on FM
