Mystery 21 Radio

Monday, November 30, 2020
This morning, while casually exploring the shortwave bands from home using Twente WebSDR, I stumbled across an AM transmission on 4860 kHz. The station was playing some great Euro Pop so I immediately hit "record" and switched over to my local shortwave monitoring set-up (AirSpy HF+ Discovery / YouLoop antenna mounted on the balcony). It turned out that I could pick up their signal quite nicely over here too, albeit with somewhat greater noise levels compared to the WebSDR copy, owing to local QRM:

The station ID was "Mystery 21" and their Facebook page suggests that they are located in Germany. Below is the full WebSDR recording for your listening pleasure:
