HF+ Discovery

Could a serious WSPR station need only one small program and one memorable command? I built this especially for my friend Brad, K1TE. We both believe in practical P2P, point-to-point radio contacts, and we are working toward making them reliable across the breadth of planet Earth. airspyhf-wsprd is a dedicated receiver for the Airspy HF+ Discovery. It tunes, aligns to the WSPR boundary, decodes, reports to WSPRnet, and repeats: ./airspyhf-wsprd -b 20m -c VU3CER -g MK68xm No dial-frequency memorization, GUI, virtual audio cable, or Fortran runtime. ...

Setup OS and SDR Please use the latest Raspberry Pi OS 64-bit on RPi 4 or later. Using a Raspberry Pi (<=3) is NOT recommended as it has quite a bit of power supply noise on the USB ports, which reduces the performance of the connected SDR. user@rpi:/etc$ cat /etc/os-release PRETTY_NAME="Debian GNU/Linux 13 (trixie)" NAME="Debian GNU/Linux" VERSION_ID="13" ...
