content: It's Chromium-based, so differs mostly in appearance. Also Yandex is similar to Google in scope (it has loads of own services like mail, maps, music, video, news, shopping, web-analytics and so on), so it makes sense for them to create a Chrome-clone. Putin is pretty much anti-Yandex, by the way: "Yandex Sinks as Putin Hints at Stronger Internet Control", but the data of course could be just taken from Yandex's data centres by government officials. Don't know much about Shortwave Radio, sorry.
