Russian Military Radiograms are encrypted radio communications used by the Russian military and intelligence agencies for the transmission of sensitive information. These radio transmissions typically use a combination of numbers, letters, and other codes to convey encrypted messages. The specific encryption techniques used by the Russian military are not publicly known, and the messages are […]
On November 26th, 2022, I made the following recordings: Bashnya (Башня) and Gazon (Газону) were conducting tests on what appears to be the day frequency. However, the night-frequency has yet to be determined. It is possible that the F42 frequency may be used for this purpose. The tests were active on 3305 kHz and 5097 […]
On October 13th, 2022 at approximately 16:00 UTC, I observed a silent carrier on 4230 kHz USB. It became apparent that this was due to an open microphone, which was most likely caused by the female Russian operator’s lack of awareness. The microphone remained open for roughly two hours, during which time the operator was […]

To start with an attack, one first has to gain some knowledge! My initial starting point was a long time ago, when m3u-stream references first began appearing on various websites. NOTE: I am not certain if it would be wise to share the details of this adventure, as there are concerns about the potential consequences. […]
Each minute an RF burst is send into the air somewhere in the neighbourhood of my house at the frequency 868.4 MHz in AM modulation. Is this data intended for me? I dont know, so I would like to figure it out… ;-)
This heatmap is filled with alarms from the P2000 alarming system in The Netherlands. The data is from New Year’s Eve 2015 and New Year’s Day 2016, when a lot of cars and containers burned out through firework and vandalism. Website: http://www.quassi.nl/p2000/history/ If you want to play with the data yourself, you can download it here: […]
Moving to our new house gave us the advantage of a ‘new’ energy meter for electricity, clean installed with counters starting from zero. Luckely for us they installed a Smart Meter type. These type of meters have a lot of ‘smart’ ports, and one of them is the P1 port. Through this port it is possible to read […]
Wireless weather stations, car keys, wireless door bells and several other telemetry devices are transmitting their information into the air in the 433 MHz band. The modulation type which is used for these devices is mostly amplitude-shift keying, ASK. The most common ASK form is On-off keying, OOK. The following signal is transmitted each minute […]
Just for some analysis with SDR and for fun I bought a wireless door bell, a Silvercrest model Z31370B. This is a low power 433 MHz device (LPD433). SDR Sharp Quickly after starting up SDR Sharp, tune-in to the 433 MHz band, and pressing the button of my door bell, I had the following […]
Today I build my first FM radio. GNU Radio Companion makes the job very easy! I’m reading a 2MHz wide band from my SDR, where I tuned into 100.7 MHz. The following shows a part of the FM spectrum: The Audio spectrum gives me this, including the pilot signal at 19kHz which indicates that there […]
