Hungarian radio can be heard well in Salzburg in the early evening with the Slovak program Nemzetisegi Adasok on three frequencies via five medium wave transmitters:
873 Nemzetisegi Adasok, Pecs
873 Nemzetisegi Adasok, Lakihegy
1188 Nemzetisegi Adasok, Szolnok
1188 Nemzetisegi Adasok, Marcali
1350 Nemzetisegi Adasok, Gyoer
The transmitters are very well synchronised, there is absolutely no echo to be heard on either of the dual frequencies.
