This morning I thought I’d search for number stations on the bands. According to,

Number stations are shortwave transmissions from foreign intelligence agencies to spies in the field of foreign countries. They carry encrypted messages in form of groups of numbers or letters, using either automated voice, Morse code, or a digital mode.

Here are a few number stations I heard this morning thanks to‘s schedule:

M12 station (Moscow) on 13.379MHz in morse code at 16:40 UTC. For those who don’t know CW, it is repeating “931” over and over with occasional breaks of “TTT” which Priyom says means “000”.


E11 station (Warsaw) on 12.229MHz in upper sideband mode at 16:50 UTC: “niner two niner oblique zero zero”.


HM01 station (Cuba) on 11.530 in AM mode at 16:58 UTC (schedule said 17:00 UTC), groups of numbers in spanish.


E07 station (a.k.a. “The English Man”, Moscow) on 12.223MHz in upper sideband mode at 17:00 UTC, “two zero one”.


It was very interesting listening live to these mysterious stations. Worldwide passive transmissions like these make you wonder what’s going on out there on the airwaves.
