Sounds like military or other land mobile traffic out of Latin America - its pretty noisy but I distinctly heard "frequency" and several series of numbers mentioned
EDIT: listened to it a couple more times
almost sounds like an alert or emergency type "broadcast" - the tones at the beginning aren't like anything I've heard the freebanders or peskies use before...."15" "frequency" "45", "75" and a possible mention of "la plata" (literally "silver" but a better translation is "money" or "cash" - could have been another similar sounding term though, perhaps "la playa" [the beach] or "la plaza" the plaza which is a term used by Mexican drug cartels to indicate areas of operation or influence of a particular cartel...) - heard "45" a couple times, could be a numerical ID for a station or a frequency/channel. Difficult to make out what else is being said. This could be related to the tropical storm developing in the Gulf of Mexico
