I received a very nice e-mail confirmation in response of my reception report to LRA36 RADIO NACIONAL ARCÁNGEL SAN GABRIEL. On July 25, 2020 they had a special test broadcast in the USB mode from ‘Base Esperanza’ on the Argentinian sector on Antarctica. The reception was very difficult here in Europe. I only heard a weak audio at the beginning of the broadcast. The 17 meter long T2FD antenna gave the best results!
