PhantomSDR-Plus Version 1.7.0

[sv2amk]

New PhantomSDR-Plus v.1.7.0 is uploaded in the github (https://github.com/sv1btl/PhantomSDR-Plus)

Added functions:
- C-QUAM AM Stereo mode. It is best working when audio_compression="opus" in the .toml file used
- Flac encoder is converted in 16 bit (was 8 bit). This means:

Aspect                    Before (8-bit)            Now (16-bit)
----------------------------------------------------------------------
Dynamic Range             48 dB                     96 dB ⭐
Noise Floor               Audible hiss              Clean silence
Quality                   FM radio quality          CD quality
Sample Resolution         256 levels                65,536 levels
Clipping                  99.6% samples clipped     0% clipping

- New Keyboard Shortcuts are added:
l, u, a, q, f for LSB, USB, AM, QUAM and FM mode

- Improvements in the backend focusing in stability and performance.

NB! Please make a clean install. If you a user of the previous v.1.6.9 then you can only replace these files and recompile backend AND frontend. Restart the server after compile.

With the newer version we've tried also to make the server more stable.
New scripts will be soon prepared and uploaded, so to help admins to keep their server running 24/7, by checking the status of spectrumserver and receiver's driver (e.g. rx888_stream), and force the server to restart if any disconnection due to any reason occurs.
Stay in touch!
