OK. That's a DRM channel. There isn't much to compress in the IQ stream. It just looks like noise to packers... and yet... the new IQ compression codec manages to squeeze it virtually loss-less'ly.

Give it a try while it's still there:

Long time ago, SDR# defined how desktop SDR applications should look like. Now let's do the same for smartphone... and the web altogether while we are at it.

Good progress. All the mode work fine and the streaming seems to be smooth. The SpyServer streams the main FFT and the IF IQ. The DSP is done in the browser. #airspy

The best is getting even better. New tricks implemented in the "Low Power" version of the NR. #airspy #sdrsharp

A second look: When the pulsed noise was filtered away, the AGC increased the gain to fit the new envelope. Very useful.

La mia solita fortuna: mi cita una delle menti più 'brillanti' di X, @sonopochi . Prima di portare Panna fuori, ho buttato lì due agent per vedere chi è. Nessuno spoiler: dal 2010 su questo social, un profilo così non l'avevo ancora visto. Se siete curiosi, link nel primo commento
