Where would I be with a little help from my friends? I heard Blue Radio Chella on 90.2 MHz, but my report remained unanswered. Artur Fernández Llorella was so kind to help me to get in touch with Alex Selfa, director of the station. Within a day I got a nice email confirmation:
Blue Radio is a local station broadcasting on 90.2 MHz with 2.5 kW power from Chella. Headquarters are in Xátiva, 50 km south of Valencia.
Thank you Artur!!!
