so ive been messing around with my audio chain on SSB for a few months now and wanted to get some actual opinions from people who run SSB regularly. im running an IC-7300 and for a while i was just using the stock mic (the one that came with it, the HM-219 or whatever it is) and honestly it was fine but i kept getting reports that i sounded a little muddy or sometimes a bit hollow depending on conditions.

tried rolling off some of the bass in the TX equalizer and that helped a lot actually, like bumping the low end down a couple dB around 100-200hz made a noticeable difference in reports. but then i also started playing with the TX bandwidth setting and kept it around 2.4kHz which seems to be the sweet spot for me without killing too much presence.

my question is basically — how much of the audio improvement stuff people talk about online is actually meaningful vs just tweaking for the sake of tweaking. like does mic choice really matter THAT much on HF where the bandwidth is already limited, or am i overthinking it. also curious if anyone has strong opinions on whether speech processing actually helps or just makes you sound compressed and harsh. i run it pretty light right now, maybe 10% on the IC.

mic choice absolutely matters even on HF and ive argued this point probably a hundred times on various forums. the thing people miss is that a bad mic introduces problems that you then try to fix downstream with EQ and processing and you end up chasing your tail. something with a flatter response in the 300-2800hz voice range just gives you cleaner material to work with from the start. that said you dont need a $300 studio condenser, something like an Heil PR40 or even the cheaper PR22 makes a real difference over the stock dynamic that ships with most rigs.

on the speech processor question — yeah it helps if you use it right. the key is setting your audio levels properly BEFORE you touch the processor. most people crank their mic gain too high, slap the processor on, and then wonder why they sound like they're transmitting through a tin can. get your ALC sitting at the top of the green and barely kissing the yellow with the processor OFF, then bring the processor in just enough to get maybe 3-4dB of average power increase. that's it. beyond that you're just distorting and killing your intelligibility.

yeah the EQ thing is real, i run an FT-991A and spent a weekend just listening back to recordings of my own transmissions on a second receiver and it was kind of eye opening honestly. cut the low mids a bit and boosted slightly around 2kHz and people started coming back with way better reports. wasnt expecting such a noticeable difference from just that.

one thing i'd add — monitor your RF drive too, ive seen people push their finals pretty hard thinking more power = more readable and it just creates splatter that makes everyone around you on the band annoyed and your actual audio worse. running clean at lower power beats a dirty high power signal pretty much every time for actual communication quality. anyway thats just my experience mileage may vary and all that
