A secret message in a Colombian song gave hostages hope
I struggle to believe that if a hostage with military training can notice and decipher the hidden morse code, that a hostage taker with paramilitary training wouldn't also spot it. But then it's probably not too much of a problem if they did, except for maybe shutting of the radios.The section of the song with the morse code almost sounds like there is interference. Maybe when played on the radio in the jungle it would be less obviously "odd" than when in a high def digital format.
