Radio Maria operates 95 radio stations in many countries around the world. I have received Radio Maria stations from Austria, Colombia, Italy, Venezuela. A few years ago they were even active on the former Dutch national radio frequency of 675 kHz before this transmitter was closed. But unlike similar world wide religious broadcasters like AWR or TWR they have no presence on shortwave.
Mr. Lopez from Radio Maria España was so kind to confirm the report of my reception made during a Sporadic E opening on June 24th. I sent my report to radiomaria@radiomaria.es . Unfortunately their are 4 stations present on this frequency, all low power. Given reception conditions that day my guess is that Toledo (2kW) was the transmitter I received, Marbella being less likely.
