This is how the the WinradHD waterfall at the UVB-76 Temporary Internet Repeater looks for past 24 hours (this image is updated every 15 minutes. Look at the time and date (UTC) on the bottom left corner to see when exactly it was captured). Note, that in order to see the most up to date capture, you have to click on image, as the thumbnail preview may or may not be from the latest screenshot!
