Testing my MSI.SDR, a chinese 50 Euro 12-Bit SDRplay RSP-1 clone.
Works quite well with SDRuno software/driver and VB-Cable.

A result for 157mins @ 99.9% CDA / 22.4dB max SNR.

At ~13:00 an AM carrier appeared affecting SNR and decoding. I assume that it is the same QRM from the same origin which noticed last year.

A result for 102 mins @ 99.8% CDA / 26.1dB max SNR.

The effect of QRM on the SNR figure can easily be seen in the plots.

A result for 158 mins @ 99.8% CDA / 24dB max SNR.

"Staying home" I spent some time building a forgotten mini Whip, designed by pa0nhc. I tested it today without taking any special measures to avoid of picking-up noise. The mini Whip was hang inside the attic below the roof. The output signal was about 20dB less compared to that of the ALA330S loop antenna which I mainly use in the same place.
