Part of our Yaesu FTX-1: The Complete Guide.
Out of the box, SSB audio on most radios is a compromise, and the FTX-1 is no exception. A few menu adjustments made a real difference in how I actually sound on the air, especially paired with the Heil PRO 7.
Mic gain, set once, checked with a real report
Default mic gain tends to run hot, which produces exactly the overdriven, distorted audio you hear too often on the bands. Set your gain conservatively and get an actual audio report from someone you trust rather than guessing based on the ALC meter alone. ALC gives you a rough guide, but a real ear on the other end catches things a meter won’t.
Compression: less than you think
Speech compression can help you punch through noise, but it’s easy to overdo. Heavy compression makes your audio louder on average but also flatter and more fatiguing to listen to over a long QSO. I run mine light, just enough to even out my natural volume swings, not enough to change the character of my voice.
EQ tuned for the mic, not the factory default
The factory EQ curve is a generic setting that doesn’t account for whatever mic you’re actually using. With the Heil PRO 7, I found the low end needed a slight cut to avoid a boomy sound, and a small presence boost in the mid-highs helped intelligibility without sounding tinny. Your settings will differ with a different mic, but the point is the same, don’t leave EQ at default and assume it’s optimized for your specific setup.
How I actually dialed this in
- Set gain conservatively, then get a real audio report, not just an ALC reading.
- Use light compression, not heavy, unless you’re specifically fighting through poor conditions.
- Adjust EQ for your actual microphone, not the factory assumption.
- Recheck settings if you switch microphones or headsets, what worked for one won’t automatically work for another.
This took a few QSOs of tweaking and asking for reports before I landed on something I was happy with, but it was worth the time. Clean audio is one of the cheapest ways to stand out on a crowded band.
