This June North Korea has resumed its Number Station broadcasts on Radio Pyongyang. The station V15 has been defunct since 2001, but it has been reactivated!

The most interesting discoveries are often due to coincidences. Hans Christian Ørsted accidentally discovered elecromagnetism, and I accidentaly found a man, who helped to create an automated voice device for OLX.

This book is a memoir of Vladimír Peták, who worked as programmer for Technical directorate of Ministry of Interior in the 80s. There is no top secret information or StB of...

Buzzer is not transmitted from Kerro anymore, new military marker on 4525 USB

09 August 2015

The Russian military network The Buzzer on 4625 kHz is not transmitted from the Kerro transmitter site ("Irtysh") anymore. It seems that the Russians are reverting to their old structure, when the frequency 4625 kHz was only used for the Moscow Military District. At present, The Buzzer appears to be broadcast only from the 69th Communication Hub in Naro Fominsk. A new military marker, similar to The Buzzer, The Pip, The Squeaky Wheel and S5292, was discovered on the frequency 4525 kHz,...

24 January 2015

The Swedish Counter Intelligence Säkerhetspolisen (SÄPO) has recently published a story about a Swedish double agent who was the recipient of S10 Bulgarian Betty, an old Czechoslovak number station. totoCZ comments: What's interesting is that it's read live, and uses "=" (Equal sign, "Rovná se") instead of "Attention" (Pozor). The shortwave number stations legend, Jochen Schäfer, has confirmed he remembers hearing this old version in the late 1970s. We've heard a similar record...

Priyom Discovers Polish Intelligence Digital Transmissions

21 December 2014

On November 25th, 2014, we noticed a transmission made with an FSK digital mode used by Polish intelligence, which started an investigation of its internals. This system has been in use since at least 2009, and a decoder for it is already included in certain expensive software, but little of its operation habits have been documented in public sources. This system uses the baud rate of 100 bd, the shift of 740 Hz, and a custom 16-bit alphabet. POL FSK without a message (December 8th, 2...
