For those of you following the mystery of two phone numbers stations found from postings on Craigslist, I have interesting news: A third posting, and a third message, have appeared.

The phone numbers stations, when called, play a short message reminiscent of ordinary numbers stations normally heard on shortwave radio. On May 8, someone posted a message to Craigslist with a telephone number which, when called, played such a message, and on May 29, a second message was posted to Craigslist with a different telephone number and a different message.

I find these messages very interesting. I wish I had more time to devote to learning about cryptanalysis. I'm definitely in the camp that thinks there's a message here and that it's discoverable. I doubt it's anything very important (national security), but that doesn't curb my desire to know what it says.

The story about phone number stations posted to Craigslist has been mentioned here before. This is one of those interesting little mysteries. The hearsay only adds to it..

People have suggested that the messages are pranks, or are some sort of commercial gimmick. But at least one person, who is in the U.S. military, says he sent a copy of one of the messages up the chain of command and was promptly notified that it was classified and he wasn’t cleared to know anything further about it. I don’t know whether this is standard operating procedure for any encrypted message or whether it indicates that there’s something to be found.
