Please pardon my ‘noob’ question. This might belong in a GNU Radio forum.
The SDRuno manual states, “SDRuno files can be opened with any tools that support that file format [i.e., Wav]”.
Are recorded IQ streams out of SDRuno known to be valid for use with GNU Radio? And do the facilities to read them in exist?
VLF station SAQ (Sweden) is tough to copy in North America. I have this notion that “A New Noise-Reducing System for C.W. Reception” by the late Don L. Hings (QST June 1947) could be implemented in software.
