Airspy HF+ Discovery / SDR# Daytime RX of Medi1 from Amsterdam

This is a quick demo of the Hardware and DSP capabilities of the Airspy HF+ Discovery / SDR# (SDRSharp rev 1860) combo in the LW band in day time. The atmospheric crashes were reduced using the Wideband and Narrow band Noise Blankers. The DSB demodulator was selected along with the "Lock Carrier" to implement a robust Synchronous AM Demodulator. Given the signal symmetry, there is no need for the "Anti-Fading" option, which was left off. The IF Noise Reduction gets rid of most of the noise without adding much artifacts. The AF Noise Reduction gets rid of the remaining noise and any new artifacts, leaving a good signal. Overall, the DSP processing added a virtual equivalent of 40 dB of SNR to the original signal of 30 dB SNR.
