SSB audio always sounds muddy on my end - what am I missing

 Loading...

so ive been on SSB for about two years now and i keep getting reports that my audio sounds bassy or muddy, like people say they can hear me fine but it doesnt sound crisp the way some of the guys on the band do. im running an IC-7300 into a stock mic and i know i know everyone says the stock mic is fine but i wonder if thats actually part of the problem here.

i did mess around with the TX bandwidth a bit in the menu but honestly wasnt sure what i was doing. currently sitting at maybe 2.4kHz if i remember right. compression is on but i dont know what level is too much, right now its around 4 on the ALC. the room im in is pretty live acoustically, just a hardwood floor office with not much on the walls. could that be part of it too? i feel like i hear guys on the air that just sound punchy and clear and im not sure what combination of things gets you there.

not looking to sound like a broadcast station just want to be readable and not have people asking me to repeat myself on pileups

the room thing is more of a factor than people admit. reflective surfaces cause comb filtering and it just makes everything sound weird and phasey, especially in the mids. a moving blanket behind you or even just a bookshelf full of books helps a lot more than buying a fancy mic.

on the 7300 specifically the TX eq is actually pretty capable if you dig into it. i run a slight cut around 200-300hz to tighten up the low end and then a gentle boost somewhere around 2kHz which is right where speech intelligibility lives. and yeah pull the compression back, 4 might be fine but watch your ALC meter while youre transmitting into a dummy load, you dont want it pinned. a little ALC action is fine, a lot means youre overdriving it and that could be whats causing the muddy sound more than anything else.

also worth checking if TX bandwidth in the menu matches what you think it does, theres a few settings in there that interact and its easy to have something set from a previous experiment that you forgot about

yeah the stock hm-219 mic on the 7300 is actually decent, people dump on it but ive had good audio reports with it. the issue is usually the settings not the mic itself. one thing that helped me was getting a buddy to record my signal off the air and play it back so i could actually hear what people were hearing instead of just going off reports. makes it a lot easier to diagnose.

also are you monitoring yourself on the receiver while transmitting? the 7300 has a monitor function and once you start actually listening to yourself in real time you catch stuff immediately
