This is a partial FT-991/A demonstration of its DSP filtering capabilities. This is a recording done in May 01, 2020 in HF 40m band mode, phone, LSB. It demoes the DNR, Bandwidth and Shift, in order to get a more comfortable reception. Later on the video (around 7:55), we proceed the demo - now with S6+ of noise floor, thanks to a rogue LED lamp.
