V32 Farsi/Iranian numbers station
7842kHz USB
On the same day, after the start of the conflict between the USA and IRAN, transmissions of numerical sequences in Fārsī language (فارسی Fārsī, persian language spoken in Iran) began on the frequency of 7910 kHz USB; radio enthusiasts initially thought it could be an new Iranian numbers station.
The first logs of the 7910 kHz transmission emerged on February 28th 2026, many radio listeners have posted various videos of this mysterious new station on YouTube. It seems like the broadcasts always happen at the same frequency every day, the transmission times during this period are at 18:00 with a repeat at 02:00 UTC.
Since March 5, transmissions have been heavily jammed in AM by a signal identical to the Iranian bubble jammer. Everyone was waiting for the 18:00z broadcast but it didn’t broadcast for a few days, in any case at that time the bubble jammer was taking preventive action.
Broadcasts resumed on March 7th on the frequency of 7842kHz with a long message lasting over an hour; a typical Microsoft Windows sound was heard during the broadcast, which is not unheard of as it already happened to G06 and E06 in 2017 and 2018, and E10 in 2010.
What we know about this station is just the tip of the iceberg; the information below is based on objective data actually heard and on estimates and reconstructions by radio listening enthusiasts.
Some sources, following signal triangulation and multilateration (TDoA), available on various SDR receivers in the network, indicate that the source is outside Iran, further west, in the Red Sea area or Israel (nearby areas), other sources instead report the possible transmission area in Central Europe (Germany). Furthermore, transmissions have occasionally been jammed by the Iranian bubble jammer, the same signal that disturbs Radio Farda, a historic anti-regime station, suggesting that this station’s purpose may be hostile to Iran.
Radio Farda is an external service of Radio Free Europe and Radio Liberty, funded by the US; it broadcasts counter-information to the Iranian regime (from outside Iran), and for this reason its broadcasts are jammed.
Moreover, some comments on the YouTube videos point out that the voice has a Russophone accent.
The fact that the signal does not appear to be radiated from IRAN and that a possible Iranian jammer may have disturbed the signal is fueling further uncertainties as to whether it could be Irianian or against Iran. This aspect will be discussed in a next paragraph.
At the moment, the ENIGMA2000 group has not yet released a bulletin, the Enigma designation V32 was assigned on March 3rd, 2026; at the moment there is no official “nickname”. The nicknames that radio enthusiasts are starting to use to identify this station are currently two: Farsi (فارسی Fārsī), due to the language, or else tavajjoh (توجه, “attention”) because this word is pronounced in the messages.
This page was the first to address the topic in question; since it is a recent development, the text may undergo revisions in the coming days.
A special thanks to everyone who is providing information to keep this page updated, THANK YOU!

Signal Characteristics
Radio amateurs monitoring the frequency have reported several recurring traits:
- Male voice, synthetic or pre‑recorded; the broadcasts can last more than an hour
- Numeric groups delivered with consistent pacing
- Clear audio, suggesting a modern, well-maintained transmitter
- Beeps, It is possible to hear, every three seconds or a little more, a dual tone (620 and 925Hz) underneath the voice. This is probably the PT override warning tone active on new L3/Harris radios; it’s automatically inserted into the audio path on both receive and transmit to let you know you’re operating in the clear, while the radio’s default setting is for ciphertext. So, it’s either an AN/PRC-160 or 150. Or the non-CCI versions of both, i.e., the RF-7800 or 5400. Thanks to the source in the comments for the information
- Strongest reception occurs in Italy and Southern Europe, consistent with a Middle Eastern source.
- The ≈ 41 Meter band (7.842, 7.91 MHz) it is commonly used by broadcasters and utilities, offering stable nighttime propagation to Europe and the Middle East. At a few hundred kHz, we can find, for example, Radio Romania International, Radio China International, Radio Voice of Turkey, Radio Cairo, which currently also broadcast in Italian, BBC and many others in various languages. Polish numbers station E11 is also currently broadcasting on the same band, at 7317 kHz.
Hypotheses Pro or Against IRAN???
Initially, since the numbers were dictated in a language commonly spoken in Iran, it was thought that it might be an Iranian numbers station. Furthermore, the probable restriction of the Internet or the collapse of the Internet network in that area may have prompted the broadcast of these messages via radio.
As mentioned, following approximate triangulations that “see” the source of the signal outside of Iran, and the jamming actions, the doubt arose that the station was created with an antagonistic purpose towards Iran. The transmitter thought to be used is Western, in Iran there is a national company for this type of radio equipment.
And what do you think? Let me know by leaving a comment at the bottom of the page.
If you want to try transcribing the sequences, the numbers correspond in Farsi language to:
1 Yek, 2 Do, 3 Se, 4 Chahâr, 5 Panj, 6 Shesh, 7 Haft, 8 Hasht, 9 Noh, 10 Dah.
In the age of viral videos, real-time news, and online SDR receivers, the appearance of this new numbers station has attracted unexpected attention from numerous enthusiasts and the press, and it’s being talked about everywhere, on social networks, forums, and so on.
It’s not every day that a new numbers station “pops up” on the air; in fact, it’s not even every year; perhaps it happens… every now and then. Enthusiasts are now accustomed to the news that a numbers station ceases broadcasting, having reached the end of its usefulness. Despite the geopolitical events of recent years, no changes have been observed in the numbers station’s schedule; in short, no numbers station has broadcast more or differently than in previous years.

I logged it at 0200 UTC on 7910 khz USB on 3 March 2026. It comes in and out, but I can hear it. Right now it’s still going for 20 minutes so far.

Apologies, my location is Jacksonville, NC.

Guys, I see fascism in this article. When it comes to Gaza or Iran, when there are interventions by Israel and the US, I see nothing else to fascism in this american or israeli numbers station. Free Palestine!!!

Was thinking the same thing as I read this.

You’re a f*cking moron – get educated about numbers stations before you come in here and shoot your mouth off.

Wow okay that’s rude 🙁 But how do you know that Anonymous isn’t educated about numbers stations? And what did they say about numbers stations anyway? I think about liberal and anti-fascist thought

Greetings. Thanks for the effort of documenting this, and referencing our V32 page at Priyom.org ! A few comments, since you make a good point about trying to remain accurate about the recent developments with this new station.
The station’s first known transmission is actually February 28th, 18:00 UTC: funnily enough, one of our member here at Priyom even spotted and reported it within a minute of the beginning of the TX! 😋 Probably it was concurrently reported by plenty other monitors at the same time, as the station isn’t very discreet… So we do believe that this was its very first transmission too indeed: if it was activated because of the war, well the first strikes happened that morning just 12 hours earlier, so it couldn’t have been before. Also our shortwave Time Machine failed to bring up any prior transmission of it on that frequency as far back as beginning of the year; but there could always have been insufficient propagation of course. And although I haven’t had first-hand contacts with ENIGMA 2000, it is my understanding that the V32 designator had already been assigned on March 3rd, not March 4th (nor April 4th).
Regarding the origin of the transmissions, it is in indeed tricky, and we need to be very careful about attribution, as evidence is far from enough so far to draw conclusions, and everything remains unconfirmed. To be clear, we couldn’t achieve any full triangulation or multilateration; but the results we did obtain seem to rule out Iran as the origin. Personally, I determined a VERY IMPRECISE bearing of 140°/320° from Paris, France (Iran is 90° from here). Partial TDoA multilateration results seem to coincide with this.
Now as for my personal hypothesis, I think that the scenario of an actor with an infiltrated network of agents reachable through a numbers station ready to be activated within barely 12 hours of the beginning of the war, is only realistic for two countries: Israel and the US. If the US, I suppose the transmissions could originate from the shortwave facilities at the Sigonella NATO base. But again, WILD UNCONFIRMED SPECULATION.

The Iranians have now started jamming 7910 kilohertz USB since 5th March, 2026 transmission at 0200 UTC. No Farsi Number Station heard at 1800 UTC on 5th March, 2026. The Iranians started jamming the frequency from approximately 1815 UTC.

The periodic dual tone beeps you are hearing is the PT override warning tone active on most new L3/Harris radios, it is automatically injected in the audio path for both RX and TX as a warning that you are operating in plain text while the radio preset is configured for cypher text. This means that V32 is using a Harris Falcon III or II HF radio and didn’t even bother to configure it correctly.
So that’s an AN/PRC-160 or 150. Or the none CCI versions of either, that’s the RF-7800 or 5400.
To me this strongly suggests that V32 is aligned with the west as the Iranians would not have easy access to this equipment. They could get some on the grey market I suppose but I can’t imagine why they would when they have domestic industry for this.

Wow that’s really great information, thanks for spotting and reporting this! We favor evidence-based research, so could you please upload a video demonstrating this for all of us to see?

Due to bubble jammer on 7.910 Mhz, the frequency of V32 has now changed to 8.742 Mhz
linkfanel
That’s really 7842 kHz, not 8742 kHz – typo I guess.

Since today, the speed has been slowed down somewhat, apparently to make it easier to copy / read.
I also have bad reception at my location towards the direction of the Gulf States , it seems therefore unlikely to be of Iranian origin. I am able to copy fine until the typical 40m propagation seems to drop in the evening (after the grey line disappearing). If I compare reception with similar signals, reception seems to run parallel with signals from (Southern) Europe… I have also just heard a (Windows) background sound, also already reported by others.

I have done 17 triangulations on this signal, by means of TDOA in KiwiSDR, each of them 1 minute long, making use of 6 receivers per attempt. 7 of them all point straight to Switzerland (Alps). The others are still directly around Switzerland and can be explained by propagation and other nearby signals. It is clear as night and day, where this signal originates from. Looking on a map of Europe, if one was to choose an ideal location for a radiosignal to reach all assets of interest, this would make perfect sense, since it would indeed be the most logical choice. There is an Iranian embassy in Bern (extremely close to the centre of the measurements). I would almost think that the people doing this transmission are related to there and have set up a transmitter location nearby. During transmissions I have heard a cooling fan switch on, also heard a Windows noise in the background (used for the narration of the numbers?) and even an open microphone rolling across the table. During the first days a dual beep tone could be heard as well, resembling what might possibly be a Harris army shortwave transceiver.

Hello,
Switzerland is a possibility, but it’s outside of the area where we get our most consistent and precise TDoA results. You note yourself that a majority of your results do NOT find Switzerland, but you find reasons to dismiss them: be careful of confirmation bias, it’s something we easily fall for.
Considering that this station operates on a single frequency, I would tend to believe that it targets assets that are all in a single area – Iran – and that reaching all assets is not a challenge: otherwise, they would most probably just use different frequencies. Even without getting into more operationally involved per-recipient schedules, they could transmit on an array of several frequencies to ensure reach, like HM01 of HFGCS do.
Also I don’t understand why you think Switzerland would be the ideal place, can you explain? Is it because of the elevation? But transmitter elevation doesn’t matter for shortwave as it’s not line-of-sight, and in fact mountainous terrain can hinder shortwave operations. Bear in mind that Bern is NOT actually in the Alps, it’s in a valley between the Alps and Jura Mountains, at an elevation of only about 600 m.
Are you able to share your TDoA results’ charts, with the intermediate arcs? It would be interesting to review. The TDoA algorithm will always compute and output a result, but unfortunately it does so even when that result is completely unreliable and irrelevant, without warning you about it. Thus raw TDoA results are highly subject to interpretation, to weed out unreliable results, and guess at the accuracy of remaining ones – and confirmation bias is still a pitfall there. There is already misinformation that’s getting picked up and spread online, locating V32 in Tanzania, based of a candid interpretation of a grossly unreliable TDoA result… That’s why it’s crucial to make detailed reviews of TDoA charts!
