This is a sample of a 80m band QSO, in digital voice, using an ADR9000MKII voice modem. the propagation was unstable as you can see. Thanks to CT1BWI and CT1PT to help me on this test.

    Thanks G0TMX for your post. You can see how the ADR9000MKII, can decode signals under S1. We are experimented some dropouts at week signal, because CT1PT was narrowred the bandpass from 3KHz to 2,4 KHz. Note that this device working extremaly well under low sognal conditions, but only when the QRG is clean.This system is very sensitive to the QRM on the band.
    You can see de other video in the 40m band, with a stable S9 signals.
