FM Transmit Audio Poor

Postby dlambeth » Fri Feb 12, 2021 10:47 am

I have tried getting the FM transmit audio quality to sound good, but to no avail. I have used the 100b and th 200D, and I have a friend who has a 7000DLE and they all sound very poor on FM. Has anyone ever been able to get this thing to sound at least okay on these units? It almost unusable in it's current state as it sound very bad. It would be kind of sad if these fine units fail to sound at least as good as knob radios. I used to own an FDM-DUO and it's TX audio was just amazing.

Thanks

Are you using PowerSDR or Thetis?

Have you already enabled "Pre-emphasize Before Limiting"?

Ahh, this did the trick. Now it sounds much better on FM. Thank you so much, I was really on the brink of frustration.
