FreeDV 2020

[FS75M1]

Hello.

First I would like to thank everyone involved in this neat project.

I had success sending FreeDV 2020 with cable from pc. Reception with usb sdr.

The modulated signal could do with a boost from 1700hz.

Is it just my tx that have this problem?

With a little boost 2020B would not be far.

I tried already with different levels on the drive. I also tried to pass the FreeDV signal through the usb cable.
