Radio Austria classical programming
 

For those who have not discovered it and don't mind some interference
with their Schubert, Mozart and Beethoven, I'd recommend tuning into
Radio Austria at 0400-0500 on 6155 most any night for an experience
that, to me at least, defines much of the "romance" of SW listening.
The fidelity is far from high, but there is something about hearing
any number of great pieces of music emanating -over the air- from the
region where they were originally created that is close to magical.
Announcements are in German, but it is fairly easy to decipher the
composer and the piece.
