A useful source of broadcasting information from inside Ukraine is this site, which looks like an equivalent of Radio Today: http://www.proradio.org.ua/news/2022mar.php
The page is in Ukrainian, but easily translated by any web translation service. The page says that the Ukrainian Radio's English service resumed a couple of days ago, with a nightly broadcast (on the single public radio service) at 03:00 Ukrainian time which appears to be aimed at an evening audience in the US.

Google translation of the item on March 3:
Ukrainian Radio not only broadcasts 24/7 in Ukrainian, but also resumes the work of the English edition of Ukrainian Radio! At 3 o'clock at night (20:00 in New York) - the first issue of news in English, where journalists around the world will tell about Russia's war crimes against sovereign Ukraine. Then - regularly and more often. Frequencies of Ukrainian Radio:http://ukr.radio/maps.
