Hello everyone!

Today, we release another update of the ExpertSDR3 User Manual (SunSDR2 DX edition). The main changes are:
- Expanded Drive slider description
- Addition to the Firmware Manager
- Link to the mic signal adjustment guide

But the main dish is the Italian version of the user manual! For that we thank Roberto Boccadoro IZØAEX!

Please share your suggestions and ideas regarding the user manual on GitHub.
