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… ;-)
The burst is only 170 msec, so it can’t be that important ;-)
After zooming in we notice that there are long and short pulses. Also here a long pulse represents a binary 1 and a short pulse represents a binary 0. So lets give this a go….
So what we get is 10 bytes of data:
00000000 10011100 11110101 01101101 11111010 11111001 11101011 00111010 11011011 11000001
Other samples I received are:

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 […]
Frequency Spectrum Heatmap and Timeline Heatmap See https://ukraine.quassi.nl for the live data. Radio communications across the Russian forces are realy poor, which leads to makeshift solutions! Webreceivers to use: List with WebSDRs: List with Spyservers
