Kinda surprised this hasnt been discussed here.
A fellow from Belgium has been developing a "bloat free" and open source piece of sdr software that gets rid of the problems that SDR# has been prone to for all of us.
While im not a fan of some of the stuff he does [not in regards of this software, but the way hes treated some of his fellows], im still going to post this git repo and main site for all who want to see the alternative to SDR#, but in C++ instead...
