Thanks for the test; much appreciated because I (and DF0WD) is still QRT on LF.
Unfortunately, in a domestic environment I could not decode your QRPPP signal on 40m yesterday. Was it on the whole night ?

Slightly "off-frequency": I am frequently monitoring the VLF range with a colour azimuth spectrogram as invented / presented by DF6NM. There is a remarkable change of the azimuth of reception (only a few degrees), which seems to depend on the time of day, and also on the frequency - for example, the lower part of the MSK signal arrives from a slightly different direction (+- 1°) than the upper part. DHO38 on 23.4kHz is only ~100km away from here, so the groundwave should be dominant, but even there is this strange nighttime effect. On "DX" signals like NWC (19.8kHz) the effect is not visible.
