Polskie Radio has turned off the longwave frequency 225 kHz on November 2, 2015, at 9:00 clock until November 22, 20.00 clock local time.
This is justified by the installation of a DAB antenna and extensive maintenance work on the transmitter.
According to information from Polskie Radio, the longwave 225kHz is still used by 40 percent of the listeners who follow the broadcasted program "Jedynka".A greater interest from abroad is noticed as well.
