I tuned to 8743 usb earlier this evening. Two Spanish speaking men were
"talking" to each other by reading series of letters and numbers. I
figured it was some bizarre variety of numbers station. However, I
started writing down what they were reading and the letters were
spelling English words. I picked up the words "vessel", "reassure" and
"any".

Anyone have an idea what this was? Why would these Spanish speaking men
be spelling out English words to each other?
