Listening to LRA 36

by TomL

I finally had time to go outdoors to listen to LRA 36, Antarctica. People were gushing about how well it is being received. My location was a park across the street from the Forest Preserve I usually go to (the Forest Preserves are shutdown and gates locked after sundown). Even though it was after sunset, this Park has no gate or chain to prevent people from parking there. In the dark, I setup the trusty amplified Loop-on-Ground antenna, SDR, and laptop. Solar Flux Index about 179, K index 2.

Started recording and, NOTHING! ARRGH. But I had just heard it at home in the noise!?!? Waited about two minutes and all of a sudden music started playing in the middle of a song. S6 – S7 strength with lots of fading. Very cool. 20 minutes later, went off the air. Then 10 minutes later, came back on again in the middle of another song. They must be tweaking the transmitter. This feels like the 10 kW transmitter; no way could a 1.5 kW be this loud over 12000 kilometers! Also, an advantage with IQ recording of a spectrum is I could tune into it later. Good thing because between their tweaking the transmitter, my SDR, and the crazy propagation, I had to tune to 15475.983 kHz in order to get the USB signal perfectly in pitch.

For your listening enjoyment if you have not had a chance to hear it clearly, I have uploaded both recordings to archive.org where you can listen as long as you want. Worth listening to, playing music of Argentina music bands. Happy Listening! Here is the link to Archive.org and the audio files are also embedded below:

LRA 36 NEW TEST BROADCAST ON SATURDAY 18th

In full progress of the adjustment and improvement works in the audio chain of LRA36 Radio Nacional Arcangel San Gabriel, test broadcasts are being carried out (even on USB) with excellent signal reports which helps us to continue working together with the valuable testimony of DXers, SWLs and radio amateurs. Special recognition to the technical team : Alejandro Petrecca, Alejnandro Alvarez and Juan Benavente.

We want invite you to tune us on SATURDAY, FEBRUARY 18, 2023 between 20:00 and 23:00 UTC on 15476 khZ (USB). Reception reports: [email protected] WhatsApp messages +549 297 624 0137.

In the next week we will receive a transmitter of 1 kW modulated amplitude that has been calibrated for our new frequency at 15.475 KHZ. We will be announcing the test broadcasts of the new equipment in due course.

Likewise, once the improvements and survey of the complete audio and transmission system have been completed, a technical report will be carried out that will be taken into account for the acquisition during this year of a 10 KW transmitter equipment that will be destined for LRA36 to be put into service.

Likewise, the CCA 10 kw transmitter that was out of service has been completely disassembled, which will be transferred to the Radio Nacional transmission site in General Pacheco so that, once repaired, it will remain at the service of RAE Argentina al Mundo , thus recovering RAE’s shortwave output from our own transmission site, a possibility that will be realized thanks to RAE’s technical and human team and especially Jeff White, who, by strongly supporting RAE’s continuity in SW all these years via WRMI relay, it was really great argument for the authorities to understand that despite all the technological advances, shortwave is still necessary, and that a true public meda today must be able to be heard both on a Zenith Transoceanic, on a Sony ICF5900W , in a TECSUN, as in Radiogarden or in the latest radio app for iOS.

We´ll wait for all of you on Saturday 18 test broadcast from Antarctica from 5:00 p.m. to 8:00 p.m. Argentine time (8:00 p.m. to 11:00 p.m. UTC) frequency 15476 khz USB

We await your reception reports and if you get good listening, register and upload those videos on YOUTUBE, IG or FB.

We appreciate sharing this information among radio listeners, DXers and radio amateurs around the world.

Last Saturday, January 21, at 12:15 (15:15 UTC) Argentine time, the Antarctic shortwave radio station LRA 36 “Radio Nacional Arcángel San Gabriel”, located at Base Esperanza, began the program “Uniendo Voces”, from the cycle 2023 summer special of the RAE service, Radio Argentina abroad POR 15476 kHz (usb)

The program was carried out by Juan C. Benavente, a member of the Joint Antarctic Command and a professor at the National University of Quilmes; Marcelo Ayala, a journalist from LRA 1 Radio Nacional Buenos Aires, and Principal Corporal Nicole Valdebenito in the technical operation, a member of the Antarctic staff of that Argentine base. The proposal and general coordination is in charge of the director of RAE, the journalist and host Adrián Korol, who for years has coordinated the annual broadcasts of LRA 36.

In this first program, the Antarctic Joint Commander, Brigadier General Edgar Fernando Calandín; the head of the Esperanza base and current director of LRA 36, Lieutenant Colonel Gustavo Cordero Scandolo. For his part, the director of RAE spoke by telephone on the air before the closing of the program, emphasizing the importance and international repercussions of these wave broadcasts.

The broadcast was followed by diexers, radio listeners and radio amateurs from Argentina, Uruguay, Chile, Brazil, Mexico, Costa Rica, the United States, Spain, Germany, Japan, Ukraine, Belgium and France. Online SDR receivers (kiwisdr and websdr) in Latin America were active during the transmission with all their channels occupied and tuned almost entirely to the LRA36 frequency.

In addition, the Antarctic station LRA 36 is the only one that transmits on shortwave from Antarctica and also does so on FM for local coverage on the 96.7 MHz frequency, and on the Internet, from the site www.radionacional.com.ar/emisoras/Antarctica.

With the broadcast on Saturday, the start of the radio programming of the Special Summer Cycle is completed, which is part of the Antarctic Culture Agenda 2023 “Culture is Sovereignty”, an initiative for the sixth continent developed between the Ministry of Culture and the Ministry of Defense, through the Joint Antarctic Command (COCOANTAR).

The other radio activities in the cycle include the broadcast of “Panorama de Noticias”, hosted by journalist Marcelo Ayala, which is broadcast on LRA 1 in Buenos Aires, and the activation of station LU1ZV from Base Esperanza on amateur radio bands.

The airing was in charge of Nicole Valdebenito and Esteban Romero, members of the Navy and Air Force respectively.

ON SATURDAY, JANUARY 28, a new 90-minute broadcast will be made on short wave on 15476 kHz (USB) at 12 local time (15 UTC) with repetition at 4 local time (19 UTC)
