This presentation was originally given at the QSO Today Virtual Ham Expo in March 2021. I show how I'm able to receive and spot both WSPR and FT8 on 4 bands, simultaneously using inexpensive and commonly available RTL-SDR dongles, and GNU Radio. The technology is expandable to as many bands as your antenna will work on, and to send sub-band audio to more programs than just WSJT-X for WSPR and FT8 (eg: RBN, PSKReporter, etc.)
