The Shortwave Radio Audio Archive

Many thanks to SRAA contributor Dan Greenall, who shares the following recording and notes: I made the following recording (March 15, 2026 at 1822 UTC on 7842 kHz USB)) of V32 using a Kiwi SDR in Alvito, Italy. The "tavajjoh" (3X) announcement comes around the 6:09 mark, after which the numbers seem to run together more, rather than distinct groups of 5.

Here are two brief recordings of their drum interval signal followed by sign on in English.

Many thanks to SRAA contributor, Dan Greenall, who shares the following recording and notes:Broadcaster: Xing Xing Guangbo Diantai (Star Star Broadcasting Station)Date of recording: March 16, 2026Starting time: 2358 UTCFrequency: 19.052 MHzReceiver location: ThailandReceiver and antenna: Kiwi SDR with Wellbrook loopMode: Single Side BandNotes: This is a "numbers station" broadcasting in Mandarin Chinese, presumably sending encrypted messages to Taiwanese intelligence agents in mainland China, from Taiwan. It appears to follow a set daily schedule, and begins each transmission with the tune of a Chinese folk song played on a flute. This is followed by station ID, given twice, and a few announcements in Mandarin, then a sequence of numbers read in groups of four. An excellent article about this station can be found on the Mount Evelyn DX Report written by Rob Wagner VK3BVW in May 2025.

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 UTCFrequency: 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.

Many thanks to SRAA contributor Liam Spencer, who shares the following recording and notes:Broadcaster: Polish Radio External Service (Via WRN and WRMI)Date of recording: September 26, 2025Starting time: 02:59 UTCFrequency: 9.455 MHzReception location: Berthoud, Colorado, USAReceiver and antenna: Sihuadon D-808 with telescopic antennaNotes: After the withdrawal of most Overcomer Ministry broadcasts in the Summer of 2025. WRMI began relaying the World Radio Network North American stream to fill the empty hours. While this is great for many shortwave listeners, as we get to hear stations that used to broadcast on shortwave again. WRMI isn't making any money from broadcasting the World Radio Network, and it is unknown how long these will last. On September 26th, I recorded the Polish Radio External Service, as they became part of my daily listening thanks to WRMI. I used a cassette tape to record the broadcast. Sometime during the recording, a few seconds of the broadcast were cut as I had to flip over the tape to continue recording.

Radio Union was well heard in the overnight hours, and featured salsa, chicha, and huayno music. Long after it left shortwave, I listened to the station online, until it closed down a few years ago.
