At about 0946 UTC on 20th March 2022, I tuned in to the Radio Nacional Da Amazonia broadcasting in the Portuguese language on 6180 kHz.
The broadcast was coming from the Brasilia 250 kW transmitter in Brazil. At 1000 UTC the signal was totally wiped out by China National Radio CNR6 on the same frequency.
The overall reception of Radio Nacional Da Amazonia was poor – fair.
Below is a short video showing my reception of Radio Nacional Da Amazonia.
