We experienced good conditions towards Spain at Lista last March with no less than 102 different Spanish stations making it into our log.
One of the stations heard was SER Radio Valencia which frequently had a good signal on its mediumwave frequency of 1179 kHz, often accompanied with the signal of co-channel SER Radio Rioja.
I received a short e-mail confirming my reception of the station a fews days ago. The transmitter is listed with a power of 50 kilowatts, but I doubt it is operating on full power.
