I’v just tested a new Tayloe Quadrature Product Detector and Preamp made by LA6NCA Helge.
As the video show. I have down converted the 1st IF from the FT-1000d to somewhere around 460KHz and fed the signal to the product detector.

Cool! You are zoomed full in, how much bandwidth can you see zoomed full out? -Scott, WU2X
Hi Scott, Bandwidth is currently limited by my crappy soundcard sampling rate @ 48k.
Considering that only front end band pass filters being in front of 1st IF the potential should be the hole band if sampling rate could support it.
