There is an interesting frequency changing signal that i can't recognize at 5456kHz. I started listening to it at 19.30 UTC and it seems to be staying constantly now but i haven't seen it before on this frequency. The receiver mode was USB and the receiver is at the university of Twente in Netherlands.
i had trouble extracting the screenshot file here so there is a brief recording of the signal.
