Well done again!

Knowing the message, I looked for the W4DEX signal in Amb= erg. As a compromise between 8270.0 and 8270.1, the recorded band from the = DL0AO cardioid currently covers 8270.05 +-0.171 Hz. Fortunately this contai= ns at least the full main lobe of Dex' PSK spectrum. After unspreading, the= re appeared a small peak with 5.1 dB SNR in 35.9 uHz, equivalent to -7.2 dB= Eb/N0.
