Output power is 5W, but aerial seems to works properly so should be audible hundreds kilometers from their QTH, located somewhere in Northern Poland. Unfortunately annoing UTE sometimes makes problems on mentioned frequency.
Radio "7800" is not real name of this stations. This is my personal name of it because real name is not published yet or at least is not known for me.
