The Shortwave Radio Audio Archive

Many thanks to SRAA contributor Dan Greenall, who shares the following recording and notes: On March 16, I listened to V32 using the SV1BTL SDR in Athens, Greece. The voice came on at exactly 1800 UTC, but right up to 1759, the bubble jammer was being heard on that frequency. There did not appear to be any jamming during the actual "broadcast". The signal was very strong, averaging 20 dB over 9. At 1823 UTC, there were 12 users listening on this particular SDR, and 8 of them were tuned to 8742 kHz!

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.

Many thanks to SRAA contributor Dan Greenall, who shares the following recording and notes: Broadcaster: Radio Ghana circa 1971 Frequency: 11.850 Recption location: Ancaster, Ontario, Canada Receiver and antenna: Hallicrafters S-52 using a longwire antenna Notes: Back in 1971, Radio Ghana from Accra had an external service, this one beamed to North America and the Caribbean on 11.850 MHz shortwave. Here are two brief recordings of their drum interval signal followed by sign on in English.

Many thanks to SRAA contributor Jim Jordan, who shares the following recording of Radio Farda being actively jammed. Jim also shares these notes: Broadcaster: Radio Farda Date of recording: January 28, 2026 Starting time: 1700 UTC Frequency: 7.5 MHz Your location: NW UK Your receiver and antenna: Lowe HF 150 plus 50m random Notes: A bit reminiscent of trying to listen to Radio Liberty during the Cold War

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, 2026 Starting time: 2358 UTC Frequency: 19.052 MHz Receiver location: Thailand Receiver and antenna: Kiwi SDR with Wellbrook loop Mode: Single Side Band Notes: 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 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.

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, 2025 Starting time: 02:59 UTC Frequency: 9.455 MHz Reception location: Berthoud, Colorado, USA Receiver and antenna: Sihuadon D-808 with telescopic antenna Notes: 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.

Many thanks to SRAA contributor Paul Walker, who shares the following field recording of Radio Ndarason Internationale on 12,050 kHz made on October 26, 2025 at 1836 UTC in McGrath, Alaska.

Many thanks to SRAA contributor Paul Harner, who shares the following recording and notes: Broadcaster: Radio Netherlands 'Media Network' Program Date of recording: April 29, 1982 Starting time: Unknown Frequency: unknown Reception location: St.Louis, MO Receiver and antenna: Sony ICF-2001 Notes: This is a partial recording of "Media Network," though most of the program is on this recording. My interest in this specific show was the feature on Radio Luxembourg, This program is not in the Jonathan Marks archive of his "Media Network" shows.

Many thanks to SRAA contributor Paul Harner, who shares the following recording and notes: Broadcaster: Radio Union, Lima Peru July 1994 Date of recording: July 01, 1994 Starting time: 0730-0815 UTC Frequency: 6115 kHz Your location: St.Louis, MO Your receiver and antenna: Icom IC R-71-A Mode: Single Side Band Notes: Radio Union in Lima was a longtime favorite station of mine from the late 1980s through the 1990s. 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.

Many thanks to SRAA contributor Paul Harner, who shares the following recording and notes: Broadcaster: Radio Netherlands 'Media Network' Program Date of recording: April 23, 1987 Starting time: Unknown Frequency: Either 6165 or 9590 kHz Reception location: St.Louis, MO Receiver and antenna: Icom IC R-71-A Notes: I recorded "Media Network" using a timer, and reused these tapes weekly. In this case, it became a time capsule. It is also not a show that is on Jonathan Marks' archive site.

COPYRIGHT NDR Live, off-air, two-hour recording of the special annual Gruss an Bord program from German broadcaster NDR, Norddeutscher Rundfunk, on 24 December 2025. Gruss an Bord features music and greetings to and from mariners around the world. The Christmas greetings were recorded at an event in Hamburg. Relatives and friends had the opportunity to wish their loved ones at sea a happy holiday and a happy new year. The Hamburg event was recorded on the third Sunday of Advent, 14 December, in the Duckdalben International Seamen's Club and was hosted by Susanne Stichler. The program included a number of special guests including Bishop Kirsten Fehrs; Hamburg's Senator for Economic Affairs, Melanie Leonhard; the Federal Government's Maritime Coordinator, Christoph Ploß; and Vice Admiral Axel Deertz. Music was provided by the folk music duo of Frank Grischek and Ralf Lübke. The broadcast was primarily in German, however there were several minutes in English when Filipino seamen were interviewed and some of the songs had English lyrics. In addition to being carried on the NDR Info and NDR Info Spezial networks, the broadcast was transmitted around the world on shortwave using transmitters at Nauen, Germany; Issoudun, France; Tashkent, Uzbekistan; and Okeechobee, Florida, U.S.A.; and was organized by Media Broadcast. The scheduled frequencies (kHz) were: 6030 (via Issoudun) for the Northeast Atlantic, 6080 (via Tashkent) for Europe, 9635 (via Nauen) for the Indian Ocean, 11650 (via Issoudun) for the Atlantic and Indian Oceans, 13830 (via Nauen) for the Southern Atlantic, and 15770 (via Okeechobee) for the Northwest Atlantic Monitors reported that the program did not air on 9635 or 11650 kHz. This recording was made in Hanwell (just outside Fredericton), New Brunswick, Canada. It is of the transmission on the frequency of 15770 kHz for the full two hours. The recording was made primarily using a Belka-DX receiver in pseudo-synchronous (AM2) mode with a bandwidth of 50 Hz - 2.7 kHz outdoors with a Tecsun AN-03L 7-metre wire antenna Reception was quite good for the most part with a bit of fading at times. But that receiver was initially tuned to 13830 kHz with a weaker signal. However, 15770 kHz was being recorded simultaneously with a KiwiSDR 2 software-defined radio receiver in narrow AM (AMN) mode with noise cancelling and with a W6LVP indoor magnetic loop antenna. So, the recording here has about a 4-1/2-minute splice from the KiwiSDR receiver at the beginning with the remainder of the recording from the Belka-DX receiver. A few seconds of the end of the program are missing as WRMI cut over to other programming before the complete end of the program.

Many thanks to SRAA contributor Dan Greenall, who shares the following recording and notes: Broadcaster: Radio Barquisimeto, Venezuela 1970 Frequency: 4.990 MHz Reception location: Ancaster, Ontario, Canada Receiver and antenna: Hallicrafters S-52 using a longwire antenna Notes: On 4990 kHz shortwave, Radio Barquisimeto in Venezuela was one of the "regulars" on the 60 metre band here in southern Ontario Canada during the evening hours in the 1970's. On nearby 4980 kHz, you could find Ecos del Torbes from San Cristobal.

Many thanks to SRAA contributor Paul Walker, who shares the following field recording of the BBC World Service on 9410 kHz made on September 28, 2025 at 0603 UTC in McGrath, Alaska. Paul notes that this was an exceptionally strong signal to have been received in McGrath, Alaska.

Many thanks to SRAA contributor David Goren, who shares the following recording of Emisoras Jesús del Gran Poder Quito, which he recorded on cassette tape, most likely in the summer of 1989. This broadcast was received on 5050 kHz.

Many thanks to SRAA contributor Paul Walker, who shares the following field recording of the BBC World Service (French Language Service) on 13790 kHz made on Sept 20, 2025 at 1815 UTC in McGrath, Alaska.

Many thanks to SRAA contributor Paul Walker, who shares the following field recordings of the BBC World Service on 9410 kHz made on September 19, 20, and 25, 2025 at 0458 UTC in McGrath, Alaska. Paul notes: The English feed via Ascension to West Africa operates from 05:00 to 07:00 UTC on several days in late September, featuring something rare: the carrier is switched on, followed by a brief silence and then an interval signal. This sequence occurs every time I hear this transmission sign on, but I have noticed it almost nowhere else on BBC World Service shortwave, which usually just “crash starts” and ends abruptly.
