Radio Regional is at my place the most commonly logged station from Brazil on 1520. They have often a significant hum on their signal.
(April 22 at 1455 UTC!)
Eberhard Fruck is the Ass. Program Director of Radio Seefunk which I logged last summer. He was happy to confirm my reception of their station.
Simona Giorgi works at Gruppo Media Hit who owns 6 different stations covering most parts of Italy. She verified my reception of Radio Fantastica, Radio Blu Toscana, Radio Cuore, Radio Sportiva and Gamma Radio.
