Many thanks to SRAA contributor, Liam Spencer, who shares the following recording and notes:
Broadcaster: Radio Nacional da Amazonia
Date of recording: July 16, 2025
Starting time: 00:05 UTC
Frequency: 11.780 MHz
Reception location: Berthoud, Colorado, USA
Receiver and antenna: Sihuadon D-808 with telescopic antenna
Mode: AM
Notes: Here's a recording pulled from my radio archive of Radio Nacional da Amazonia from Brazil on the shortwave frequency on 11.780 MHz from July 16th, 2025. What's interesting is that this was recorded on a weekday, and usually, back-to-back music is not heard on weekday evening programming. Along with the announcers who are usually high energy are not in this recording. Around 20 minutes in, I stopped recording and resumed recording at 01:05 UTC until the end of the recording.
