Many thanks to Esperanza San Gabriel who share the announcement above for a broadcast taking place today. Translated:
Wednesday, October 14, 2020 from 11:00-13:00 (14:00 UTC) on 15,476 kHz upper sideband.
I believe their time suggests a start time of 14:00 UTC, which would be three hours ahead of Argentina time. Even though that’ll be pretty early for an opening to North America, I will certainly tune in!
