THIS FREQUENCY WAS TEMPORARY AND IS NOW NO LONGER IN USE   It hasn't been long since Russian military added a channel marker (B Marker mentioned in last blog post) to a channel - which sends monolith messages just like Buzzer, Pip, Wheel and so on - using frequency 5292kHz. It looks like the Western & Central military districts at least are undergoing some changes and/or upgrades, for the past few days the Buzzer has been also sending continuously on 3216kHz as well as its regular...

We now have a fifth Russian military circular station with a channel marker! First there was Buzzer, then Pip, then Wheel, then R marker, well let us introduce to you the D marker! On Thursday 11th February 2015 we have found a new Russian military channel marker, akin to the buzzer! This is not something we expected to find in 2015 but rather would expect the opposite, less and less shortwave usage and more movement towards newer systems. The frequency for this new channel marker is 5292kH...

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...

The following is a description of a very interesting transmission that took place on October 14th. At about 07:20 UTC we spotted a carrier on 10755 kHz, a frequency commonly used by the Russian military intelligence agency GRU for unscheduled E06 and S06 with ID 975. The carrier had a characteristic of one of GRU's transmitters - that is, the transmitter hum present on both side bands, the actual audio on the upper, and only traces of it on the lower. Expecting E06 or S06 to start any time ...

We've recently been hearing from the ID 274 of Ukraine's E17z, which is now always unscheduled, and renowned for frequent breakdowns whenever there are messages longer than 10 groups. As we learned from the old ENIGMA newsletters, it has already been like that back in the 1990s, when E17z was using the old E17 voice with longer messages. This ID still makes appearances, usually once every a few years. Looking at the logs, even those from the previous years, this ID consistently uses a ...

Priyom has scanned and uploaded all the issues of the original "ENIGMA" newsletter, that was published in the years 1993 - 2000 by the European Numbers Information Gathering and Monitoring Association (ENIGMA). These are currently very rare, and we're making them available here to preserve history. ENIGMA was a number station research group, founded in 1993 by long-time enthusiasts Chris Midgley and Mike Gaufman. They published a hard copy newsletter, first 4 times a year, then twice-annual...

Hello! Recently I got haunted by number stations again, so I started to look for various documents and other info on the web about NS. Specifically I wanted to find out more about Stasi Sprach speech generators, which generated the famous voices that are heard on number stations. I came across an article written by Detlev and Daniel from ENIGMA 2000 newsletters about NS, encryption methods, radios and more. There is a lot of interesting information so make sure you don't miss this one. Enj...

Greetings shortwave fans. Seems we have broken google calendar, so be careful using the schedule, you may have to double check it. If you see stuff missing please drop into the IRC and let us know. Events are appearing and dissapearing at random it seems and the calendar can be a whole day out. At the time of writing this post it's the 30th of May but the site is showing the calendar for the 29th of May. Very odd and I cannot figure out why this is the case. The second issue is with even...

One of our members (Who wishes to remain anonymous!) has found and been to one of the current broadcast sites of the buzzer: 60°18'40.1"N 30°16'40.5"E The Buzzer source is fed to this shortwave site and other broadcasting locations using R-414S radio relay/phone lines directly from St. Petersburg's 60th Communication Hub (codename Vulkan, from a previous phone leak in February 2014, transcript) on Palace Square. Mutiple VGDSh antennas and other arrays then take care of distributing the ...
