@DefenceGeek @EndgameExpress @MATA_osint @ArmchairAdml @UKDefJournal The prosecutor considers this a possible act of terror with the involvement of foreign intelligence. I guess it's time to put it on a map.

W związku z dzisiejszym pożarem w Skarżysku-Kamiennej prokurator z małopolskiego wydziału PZ PK wszczął śledztwo w sprawie brania udziału w działalności obcego wywiadu i dopuszczenia się przestępstwa o charakterze terrorystycznym. ⬇️

Polish Number Station E11 “Oblique” sent a ciphered message on 5409 kHz USB. The message contained 39 groups of 5 numbers. During the transmission, each group is said twice, then the message is repeated with each group said once. Received in Poland on 30.08.2026, 20:05 UTC.

Finally, the starting phrase is said again (once) and the radiogram is repeated:

After yesterday's silence, Russian military was again active on shortwave. Interestingly, there are differences in the structures of messages containing radiograms of the same structure which suggests differences in importance of the recipient stations or the radiograms.

3/4
Other times, the starting phrase contains the callsign of the recipient repeated 3x, the callsign of the sender repeated 2x and the information that there will be a radiogram. This phrase is said three times. Then the radiogram follows (5135 kHz USB; 28.08.2026; 17:52 UTC):

@CoffeReport NATO01 is leaving Poland right now. Whatever interesting was happening, it seems to be over now.

[Piotr @LzyObsrvr]

@CoffeReport This is indeed interesting. Normally such exercises happen during office hours, not in the evening.

@Hslavza My setup consists of RTL-SDR Blog V4 dongle plus a cheap Chinese amplifier (HT004). For an antenna i use a length of wire connected to a rain gutter. I don't have conditions for a proper antenna but this works quite well.

Russian military active on shortwave this evening. A couple of long radiograms were sent on 5135 kHz USB. "Dmitry" repeated 5 times in the beginning of the letter part of the radiogram indicates a message of high priority.
Received in Poland on 25.08.2026; 17:45 UTC.

Apart from long radiograms, Russian comms also include short messages which are transmitted fairly often. They consist of 2 groups of 3 letters where the 1st letter in each group is always З (Z; "Zinaida").
Here's an example from today (5135 kHz USB; 26.08.2026; 18:58 UTC).

Russian military activity on shortwave continues this evening. Although this activity seems higher than usual it doesn't necessarily mean that Russians are up to something. This could be an exercise. Here's one complete radiogram from today (5135 kHz USB; 26.08.2026; 19:08 UTC).

[Piotr @LzyObsrvr]

Here's a complete radiogram transmitted on 5056,5 kHz USB at 18:38 UTC.

[Piotr @LzyObsrvr]

Now long radiograms are being sent on 5056.5 kHz USB (18:30 UTC).

[Piotr @LzyObsrvr]

Got one message transmitted in unencrypted AM but most of the traffic today is encrypted.

High NATO activity over northern Poland now. This time they included Apache helicopters. On the radio, the same frequency in use as 2 days ago, but this time secure comms instead of open AM.

@nexta_tv It's happening again:

Lotnictwo NATO ćwiczy w tej chwili nad północną Polską. Można ich na radiu usłyszeć.

[Piotr @LzyObsrvr]

@PolishMilRadar Do tego jakiś niemiecki samolot krąży w pobliżu Bornholmu. Wiecie może co to za jeden?
