Radio Difusora Roraima 4875.25 kHz, Brazil, improved reception recently

The theme of improved SW reception from low power stations in Brazil continues. Here is one of the strongest signals I've ever copied at home from Boa Vista. Bear in mind that usually this signal is very weak - often audio is borderline imperceptible.

Recorded in Oxford UK on 28/08/17 at 02:36 hrs UTC using an Elad FDM DUO and Wellbrook ALA1530 active loop antenna outdoors. Thanks for watching.
