So many variables for audio settings. Your voice, your microphone, any other things in the chain. These make it very hard to share settings in a productive way.
Fundamentals
- Transmit bandwidth - set that first as it determines the overall potential available to tune
- Microphone level - before enabling anything set the level so that your peaks are close to 0 but not going over at all
- Equalizer - It takes time and patience to achieve the sound you want. I typically tell people to high pass at 50-100 Hz and then start poking at 120-160Hz to drop that out, then the next harmonic at 200-400Hz. Dropping in those ranges will clear up your voice and make the articulation of higher frequencies more prominent.
- Compressor - Experiment with a ratio of 2:1 or 4:1 range, drop the threshold until you hear the compressor increase the density of your voice
- AGC and limiter - Will depend on how you speak into the microphone and will help maintain a consistent level and limit the peaks
- Clipper - bring down the threshold slowly as your voice gets louder, but not until it sounds fuzzy or overdriven.
With AM I find that I remove more bottom end than SSB by a db or two as it seems that AM emphasizes the bottom end a bit more and it needs a bit more care to get it clean and balanced.
For AM I run 50-5000 pass band range for a total of 10 kHz wide. I don’t find audio response over 5kHz very useful, it’s about the practical limit given signal strength and typical noise floor on the band, much higher gets lost and is just wasted energy to transmit.
