Super Rádio Brasil in Rio de Janeiro is a regular on 940 kHz, especially if we have an antenna directed towards South America such as in February 2022. Not sure if they are really transmitting with a listed power of 100 kilowatts. If so, I would have expected their signal to be even better. Still, their signal is noted quite often, although with variable signal quality.
Super Rádio Brasil only transmits network programming from the religious Super Rede Boa Vontade de Rádio network without any local programming whatsoever (as far as I know). Marta Trigueiro, Assesoria da Comunicação sent an e-mail thanking me for listening to their signal on 940 kHz.
