I have a kind and quick reply from new quality-station Radio PlayBack International.
Really interesting venture on SW. They enclosed QSL and very detailed history of radio broadcasting starting from Einstein and Marconi and ending to PlayBack.
In the reply they stated that the station in not located in Italy (We must remember that it is a pirate station - and we are not supposed to know their closer location. So, it is broadcasting from the "island of nowhere", as stated in their jingle).
They promised photos of the equipment and I will publish them here right away!! Very interesting.
Listen PlayBack-jingle in studio-quality!
