Many thanks to SRAA contributor, Dan Greenall, who shares the following recording and notes:
Broadcaster: V32 Persian/Farsi numbers station
Date of recording: March 13, 2026
Starting time: 0226 UTC
Frequency: 7.842 MHz
Receiver location: Israel
Receiver and antenna: Kiwi SDR with MLA-30+ Active antenna
Mode: Single Side Band
Notes: Background material obtained via Radio Free Europe / Radio Liberty. This radio signal first started broadcasting on February 28, about 12 hours after the United States and Israel began bombing Iran.
A man's voice can be heard speaking Persian, counting out a series of apparently random numbers. The numbers are read out for varying stretches of time, followed by a pause in which the word tavajjoh -- which translates as "attention" -- is spoken three times. (around the 48 second mark in the attached recording)
Beginning on March 4, the signal started to be jammed, with a cacophonous screech of electronic noise that made it all but impossible to hear the numbers. The original transmission paused for a period of time, then moved to another shortwave frequency.
The transmission, that has been dubbed V32 by at least one group, is called a numbers station, a Cold War-era tool that employs radio transmissions and old-school cryptology to transmit secret messages, usually to spies around the world. It's location is suspected to be somewhere in central Europe.
The attached recording of V32 was made on March 13, 2026 around 0230 hours UTC on 7842 kHz upper sideband USB using a Kiwi SDR located in Israel. I began the recording on 7841.9 kHz, but switched after a few minutes to 7842 kHz. This will account for the change in voice pitch.
Also attached is a brief recording of the jamming signal, or “bubble jammer”, made on March 6, 2026 on 7910 kHz (V32’s original frequency) at 0218 UTC.
