For your listening pleasure: Radio Educación (XEPPM) from Mexico City. This recording was made on April 1, 2019 starting around 0125 UTC on 6185 kHz. The receiver used was a WinRadio Excalibur hooked to a large horizontal delta loop antenna—the recording was made in North Carolina, USA.
Although XEPPM’s 1,000 watt signal often makes it into North America, it’s rare that it’s so clear and conditions are so quiet. Their jazz selection on this date was excellent. Enjoy:
