I’ve been using the AziLoop system for almost a year now, and the antenna has proven itself to be excellent in terms of its versatility and reception performance. The small server runs 24/7, uses very little power and is always accessible online via the network; the timer switches the antenna on in the evening, tuning in to Asia first and then South America later in the evening. Early in the morning, the system switches off completely and grounds the antenna. My perfect partner for reception on mediumwave and on 160 metres.
One of the ‘difficult’ mediumwave DX targets here in Austria is Chile. First and foremost, because the few stations there share the frequencies with other transmitters from South America and use relatively low transmission power. On top of that, I haven’t had a good South American antenna in recent years with which I could go ‘hunting’ for Chile during the best possible reception period in spring. By setting up my AziLoop antenna, which can be rotated 360° electronically, I was finally able to make a serious attempt at this major target this spring.
In fact, there are only two stations: Radio Festival on 1270 kHz, a long-established station from Viña del Mar, also known as ‘La Radio en Colores de Chile’. Unfortunately, Radio Provincia from La Plata also broadcasts on the same frequency, and always offers a much stronger signal from almost the same direction. The second option for receiving Chile here in Austria is Radio Cristo llama al Pecador on 1570 kHz from Rancagua, the capital of the Región del Libertador General Bernardo O’Higgins. However, Radio Carraviz from Juliaca in southern Peru also broadcasts on 1570 – and this station can very often be received strongly in Salzburg.
Nevertheless, this frequency seemed the most worthwhile to me, partly because the offset of Radio Cristo llama al Pecador, at 1570.039, is a considerable distance from the Radio Carraviz signal and is therefore clearly visible in the waterfall display of the SDR software. I have now been tracking the signal closely for many days; it was easy to see, but the audio was very difficult to make out. Here we must thank the developers of the specialist mediumwave programmes Jaguar and WavViewDX; without their help, one would never be able to see and hear such weak signals in the mediumwave band with this clarity!
Last Sunday, after 01:30 UT, the signals from Argentina were stronger than those from Peru further north, making the search worthwhile. Finally, at 01:52 UT, the signal from Rancagua in Chile was stronger than the Peruvian one on the same frequency for two minutes. And although I don’t usually use the stations’ audio streams for comparison, it paid off here – exactly the same folk music was being played in the stream! Even though I didn’t hear a station announcement, it was clear that the signal on 1570 kHz had come from Chile.
Thanks to the help of Thomas Nilsson and Hans Ostnell from the Arctic Radio Club, I was able to make contact with Pastor Angel Arenas Montecinos, who confirmed the reception:
Bendiciones señor Ratzer.
Le cuento que si es nuestra radio 1570 am de aquí de rancagua sexta region de nuestro país chile .Y le agradezco por darnos esta alegría a nosotros de saber que tan lejos se esté escuchando nuestra señal.
Un abrazo grande y muchas bendiciones.
English translation:
God’s blessings, Mr Ratzer.
I would like to inform you that this is our radio station 1570 AM here in Rancagua in the Sixth Region of our country, Chile.And I thank you for giving us this joy of discovering how far our signal can be received.
A warm hug and God’s blessings.
Such wonderful confirmation is the reward for all the work at the station, for the many hours spent trying to improve the reception equipment in the hope of perhaps making mediumwave signals from other continents more audible. And such a rare reception is also motivation to listen again every day and find new stations. Our very special hobby can be so wonderful!
Over the last few days, we’ve been able to pick up some lovely early-summer mediumwave signals from South America. The thunderstorms have spared us so far, so it’s a pleasure to listen in, even if the signals aren’t always very loud.

Over the summer, I’m only using the reliable AziLoop antenna; all my other antennas are switched off completely for the first time and have been unplugged as well – given my exposed location, I want to minimise the risk of power surges and lightning strikes causing any disruption.
No particularly strong signals, but southern South America can be heard on the medium-wave band almost every day here in Salzburg.

Signals from South America can be heard from time to time on the medium-wave band, though they are usually not very loud. However, the absence of thunderstorms is helping to ensure good reception.

ABC Newsradio from Busselton on the Australian west coast, 13,547 km away – about 220 kilometres south of Perth – could be heard again yesterday evening at around 22:00 UT on medium wave 1152 kHz in Salzburg. Caution is advised when receiving the signal, as a small station from Taipei, Taiwan, can usually be heard on exactly the same frequency (1151.994) from 20:00 UT onwards.
The new AziLoop system is now fully installed. Mast height 7.5 metres, loop circumference 26 metres each. The antenna not only receives excellent medium wave signals from all directions, it is also perfectly remote-controllable and the best antenna I have at my location.
