SAQ transmission of July 2nd, 2025

This time SAQ was received with the new Perseus22 SDR receiver fed from a modified mini-whip. Perseus22 through Virtual Audio Cable sent the recovered base band audio both to HDSDR and to Argo Version 2.
HDSDR was used to record an excerpt of the audio received, while Argo V2 was used to show a fragment of the waterfall and of the spectrum

The S/N was rather poor, at least here in JN45sl, so I had to narrow quite heavily the bandpass...  This is an excerpt of what received
