I did not notice any other mode than the C/10 kHz, but we had guests here and I was not glued to the PC all the time. I just noticed that the DRM started, so I started logging. There was no audio at all until I switched off. At that time MSC was red and SDC was red. The upper part of the SNR Spectrum was missing. My log did not record any mode changes. The Doppler was high and around 1850 UTC it went over the top of the log plot window.
