Ukrainian radio has launched three new medium-wave transmitters.
Since the beginning of Russia’s open aggression against Ukraine, the Ukrainian Radio of the National Public Television and Radio Company of Ukraine has launched three new medium-wave transmitters.
Thus, today there are four transmitters in Ukraine that provide a reliable signal of Ukrainian radio in the medium-wave range:
549 AM
Dnipropetrovsk region
Zaporozhye region
Kherson region
Mykolaiv region
Odessa region
Kirovograd region
Vinnytsia region
Cherkasy region
Crimea
1404 AM (new)
The southern part of the Odessa region
657 AM (new)
Chernivtsi region
Part of Ivano-Frankivsk region
873 AM (new)
Luhansk region
Donetsk region
Thanks to the expansion of broadcasting in the medium-wave range, the signal of Ukrainian Radio can now be heard by all residents of these areas, including small towns, which do not reach the signal of existing FM transmitters.
In addition, on medium waves, the signal of the Ukrainian Radio can be heard without hindrance while driving on the territory of the areas covered by the signal.
According to the technical specialists of Ukrainian Radio, almost all radio receivers that people have today, from the oldest to the newest models, operate in the medium-wave range.
It will be recalled that medium waves are a range of radio waves with a frequency from 300 kHz (wavelength 1000 m) to 3 MHz (wavelength 100 m). Medium waves are able to propagate over long distances due to the bending of the earth’s surface, as well as reflected from the ionosphere at night (i.e. at night, the medium-wave signal is stronger).
Since the beginning of Russia’s open aggression against Ukraine, Ukrainian Radio has been broadcasting around the clock, providing listeners with the most up-to-date and accurate information on the course of hostilities and the country’s defense. Round-the-clock hosts of Ukrainian Radio broadcast live representatives of central and local authorities, heads of the Armed Forces of Ukraine and military analysts with the most up-to-date data on the situation on the front and in the cities of the country.
Ukrainian Radio is the largest FM network and the most popular broadcast radio in the country with an average daily coverage of almost one million radio listeners. In Kyiv, it broadcasts on 105 FM. You can find out FM frequencies in other cities by following the link. All channels of the Public Radio have switched to the transmission of the Ukrainian Radio signal, they can be listened to in the mobile application suspilne.radio and on the website ukr.radio.
