Polskie Radio Program I

Program I began test transmissions on 1 February 1925, and began regular transmissions on 18 April 1926 (as Polskie Radio Warszawa), one year after Polskie Radio was founded.

In 1924 the Post, Telegraph, and Telephone Act was passed, and in February of the following year, a broadcasting station built already in Poland started operation.^[1] Several months later (18 August), a privately owned company Polish Radio received a license for broadcasting a radio program. In 1935, the Polish government bought 96% of its shares and so the radio became the property of the state.^[2]

Jedynka broadcasts a program of universal character, addressed to a wide range of listeners, distinguished by a large amount of information, which is prepared, among other things, by the News Editorial Board. The program is broadcast on long waves in the amplitude modulation system on a frequency of 225 kHz from the Radio Broadcasting Center in Solec Kujawski and on UKF waves from transmitters throughout Poland, digitally, as well as via the Internet, HbbTV and satellite in the digital system without encryption (FTA broadcast). The radio station can be listened to using a telephone link - number +48 (22) 645 91 00.

Jedynka's total reception range in the UKF band (as of July 2012) covered 92.33% of the country's population and 90.19% of Poland's area.^[3] It is complemented by long-wave broadcasting.
