Mention of "el capitan", my gut says Spanish but the accent is hard to pin down. Decent signal on the COMMSIGMA SDR just before 2200 UTC on 6570 kHz 6.570 MHz USB mode.....after listening for another minute or two, this is Spanish. Mention of "the gentlemen" and discussion of what they're doing tomorrow. Heard "okay" a couple times, somebody whistling into the mic...somebody IDs as Antonio and the usual "gambio" or "cambio" end of transmission pro-word (means "over" in Spanish).
