Today I was surprised to see on Radioescutas FB Group reference to the closure of the large ZYK-656 Super Rádio station on 1150kHz serving São Paulo.
Apparently it has already moved onto the new low FM band at 80.7MHz.
Slightly confused by the appearance of the monopole very clearly on Google Earth at its location in São Caetano do Sul. Many locals have taken photos which show a completely different appearance for the location. It is labelled as a Park so presumably demolition will follow quickly.
