on 6969.9
1826 music, hum
1930 music, on 6969.87
so, well, this is the offset of Zeppelin Radio, then when there is no ID given, we should listen for a while, preferably till we hear greek songs, or at least music choices compatible with Zeppelin Radio.
The frequency 6970 today is not typical.
1940 enough to tell it's Zeppelin
