Hello Marco
Thank you for the interesting report.
Generally I got much better reports with PSK08. PSK08 had been received almost error free. To my Station: PC, Software Defined Tranceiver of Softrock RXTXv6.2, preamplifier, PA 70W.
Antenna: inverted L 50m and 10m high.
QTH: Neunkirchen a.B. / Nürnberg
Lokator: JN59NO

Hello Roland,

Copied your PSK08 transmission in JO42FD, using an SDR-IQ on an untuned HF dipole.
...
In PSK31, no decode, the signal barely visible on the spectrogram (except in the "up"-phases of the QSB).
Interestingly, the opposite here... not able to copy the PSK08, but
some acceptable copy in PSK31:

A lot of QSB and statics. Antenna 23m long wire, Perseus SDR receiver,
Spectrum lab V2.71b7. Signal around -105dBm, locator JN35SA.
