CubicSDR provides a panadapter experience, showing the RF spectrum for the band you have selected. I use it with my Yaesu FTDX3000D radio frequently, along with an inexpensive RTL-SDR adapter.I've prepared CubicSDR to be unretired from Fedora rawhide (F33), now that wxGTK 3.1 is available in rawhide. Package review ticket here:Reviews appreciated.Thanks,Matt
