Frank, seems indeed to work! Just tested during RX of station KG4HF with bandwidth of either 3 kHz or 500 Hz. See the following S/N comparison. Astonishing!

Oktober 2018 15:48 An: WSJT software development Betreff: [wsjt-devel] Improving S/N One thing I haven't seen discussed on this reflector is improving the S/N by narrowing the receiver bandwidth. It is no surprise that decreasing the bandwidth received increases the S/N, by 10 to 15 dB, sometimes more. When I see a station I want calling at -24 or so, I can narrow the BW and get solid communications. This is very easy with the graphical presentation and digital filtering of the Flex 6600, but with a little practice, could be done on any modern receiver. This means that, if we knew where the stations were calling at -30 or so, we could focus on them and bring them up to the point of making contact. Since you can't decode stations at that S/N, it would have to be done "out of band." Is there any thought being given to setting up an FT8-only DX cluster with exact frequencies? What a fascinating hobby! 73, Frank KF6E
