252.150 Activity from Chinchiná in Colombia

Lately, I’ve been hearing a regular amount of Spanish chatter on different UHF SATCOM frequencies. Here are several stations using 252.150 conducting radio checks and exchanging information. What caught my attention on this intercept was the mention of a camp in the sector of Kilómetro 41 and the mention of a specific point 500 meters below the point where Río Chinchiná and Río Cauca meet. These are very specific locations and after a bit of Googling, I was able to find an approximate location on this map. This puts them in the Caldas Department of Colombia, which is located a bit north of Pereira. Definitely interesting and bears watching.
