Unidentified station has been received on 87.8 MHz during brief final hop from Belgium and The Netherlands, at 17.25 UTC. Detected RDS PI code is: 5396! This code is being used by Jonica Radio and some other Italians, however Jonica is not broadcasting on 87.8 MHz, and there are no stations with such PI on this frequency at all, according to the FMList database. I can't identify the recorded song neither, but it is not typical for Italian broadcasters, in my opinion. Possibly a pirate?

Signal of this UNID has faded-in synchronously with signals from Genk and Sint-Pieters-Leeuw (Belgium), also 100% NL (tentative) from Hulsberg was audible at the same time on 92.1 MHz. So, if this is a Dutch pirate, the most probable location of him is somwhere in Limburg!

 

Any help with identification is very appreciated.

UPDATE: the UNID on 87.8 MHz is identified as a free radio station Zender Glaubedran. Many thanks to Jelmer! I would never IDed this one without his help.

All other stations were identified by ID jingles, RDS, playlists, podcasts, parallel frequencies or parallel web streams. Power values are ERP, distances are approximate.
