While searching for sporadic E DX I came across this regional station that I had not yet listened to: Regio 90 from Leersum. Via a webform on their site I submitted a report. The next day I received a kind email from Jos Sterkenburg confirming my reception. I happened to have tuned in to his program:

With 300 Watt Regio 90 is operating on 91.7 from Leersum. They suffer a bit from interference from the 50 kW VRT1 station in Flanders. Target audience is the Utrechtse Heuvelrug and the region just south of it. This is one of my favourite areas for cycling and I can definitely recommend anyone to visit the many castles around Langbroek and Wijk bij Duurstede!
