In August 2010, there was a landslide in a mine in the north of Chile (Atacama Desert) and 33 miners were trapped for 3 months until their rescue was carried out. It was an historic event; the eyes of the world were watching as each miner was pulled to safety.

To commemorate 10 years of this feat, Radio Club Eternautas will be active as CB33M during August 5 to October 13, 2020. QRV on 80m-70cms; CW/SSB, Digi. QSL via PO BOX 12096 Santiago.
