SDR received JT65 on 20m

Sunday I test my homebrew SDR. I get information from YU2LM's Website. Select design single LO Frequency at 140625 kHz generate from Crystal Oscillator. JT65 operating in 140760kHz. This is on range of my SDR. While operate with long wire antenna. I received first QSO between BV7RJ and JA1PLT and signal at -24db. So I think very weak but it good for experiment. It first time.
