Now the nighttime carrier is also visible on the DL0AO grabber: Since I know Stefan's EbNaut sequence, I've reconfigured the colour spectrogram to undo the PSK modulation.

The trace you saw on the DL0AO site was the carrier which was
transmitted between my EbNaut transmissions. I simply let the TX run all
the time, several days. The message is between the carriers and
invisible at DL0AO.
