Radio Brasil Central is being prepared to switch from AM to FM. There are no clear mentions about the frequencies in question, but the medium wave frequency (1270 kHz) will certainly be there.
As for the other frequencies, tropical/short waves, 4985 kHz has not been on the air for many weeks. The frequency 11815 kHz is currently (April 9, 2130 UTC) without signal, off the air. In short, this is practical proof that what is being reported about the migration makes sense.
