I had a listen to the audio. This is all Ukrainian Radio, with many IDs (in Ukrainian, including the IS, but interestingly, sometimes followed by ?Mayak IS once, then back to Ukr Radio IS), but the programming is all in Russian, especially regarding the Russian Volunteer Corps incursion into Belgorod. Thanks for the interesting link! Towards the end, (ie, 1:27) though, there *might* be some Ukrainian programming, but it's starting to fade quite badly by then.
