This station has been on my most wanted Argentinian station list for decades. The frequency 620 is mostly occupied by Brazilians R Assuncão, Fortaleza and R Jovem Pan, São Paulo. The most common Argentinian here is probably R Nacional, Resistencia. There are also Nacional stations in La Rioja and Rio Turbio on the frequency as well as R San Rafael in addition to R Provincia Misiones. The latter, LT17, was finally heard during LEM379 on January 27 with a nice peak around 0230 UTC. The stations chief announcer kindly verified my report.
