so ive been on HF for about 8 months now and mostly doing SSB on 40 and 20 meters and honestly my signal reports are pretty inconsistent. some guys tell me i sound great, others say im a bit muffled or that theres some low end muddiness going on. im using the stock mic that came with the radio which i know isnt amazing but i figured id get the fundamentals right before throwing money at a new mic.

ive been reading about TX bandwidth settings and the bass/treble roll-off stuff in the menu and played with it a little but honestly the menu system is kind of overwhelming and i dont really know what im optimizing for. like should i be cutting lows below 300hz or so? and whats the deal with the TX monitor — is that actually representative of what people are hearing or is it kind of misleading. also somebody on the air told me to watch my ALC and keep it out of the red which i get but he wasnt really clear on where exactly it should be sitting. any practical tips appreciated, been lurking here for a while and you guys seem to know your stuff

the ALC thing is super important and yeah its one of those things people mention but dont explain well. basically you want the ALC meter to just barely be moving, like kissing the bottom of the scale on voice peaks. if its pegging or even sitting steady in the middle of the scale you're probably overdriving the modulator and that's where you get the splatter and the distorted sound. back off the mic gain until you see it just nudging on loud syllables.

on the TX bandwidth, for a conversational contact i actually run mine a bit narrower than default — something like 200hz to 2800hz cuts the low mud and doesnt eat into adjacent channels as much. the stock setting on the 7300 is a bit wide imo. and yeah the TX monitor is not perfect, theres a bit of processing in the chain that can color what you hear, but its still useful for catching obvious problems like clipping sounds. honestly the best thing to do if you have a buddy nearby is get them to record your audio with their SDR or something and play it back — thats been more useful to me than anything else

dont overlook where you're positioning the mic relative to your mouth, seriously. i spent weeks messing with DSP settings and it turned out i was just talking across the mic instead of into it and at a bad distance. the stock hand mic on those radios is pretty sensitive so even a couple inches makes a big difference. also if you're in a room with a lot of hard surfaces the room acoustics can mess with your audio more than you'd think, i put a piece of foam behind my operating position and it actually helped a bit with the echoey sound one guy complained about. not saying go build a recording booth or anything just something to keep in mind
