Short Description I found this very slow frequency-modulated signal on 175.4968 MHz. In Belgium, this part of the spectrum is allocated for wireless microphones and audio connections for broadcast services. It might also originate from the Netherlands, as I'm not living far from the border. Every few minutes, the signal shifts up about 500 Hz for a while, before shifting back down.
