DSD plugin: major fix in FSK modem
Again there is no change in SDRangel itself but you must make sure you compile it with DSDcc version 1.3.0 that contains these improvements.
This is a dramatic improvement to the Digital Voice modes experience with this plugin. The clicks and distorsions on the voice are completely removed and decoding of data frames is much more robust.
DSD plugin: changes in the GUI
The rewrite of the FSK modem in DSDcc yields some changes and improvements to the GUI along with other fixes:
- Button to select/deselect matched filter although you will want it most of the time liberty is granted to the user to play with it
- When the matched filter is engaged its output is shown on the scope and not the discriminator output to fit what really enters in the FSK demod
- Button to switch between transitions constellation display (the only one previously) and symbol synchronization monitor signal display
- Signal level range and center displays
- Display of the percentage of synchronization zero crossing hits per symbol
- Display of the calculated symbol framing jitter
- Fixed the channel power display
- Fixed the monospace font type so that it displays nicely both in Linux and Windows versions.
