Even earlier, try 8950 USB for St Petersburg (formerly Murmansk) - regardless of the Russia situation, those territories who havent denounced the invasion, such as UAE, China, India, Qatar etc continue to overfly Russia airspace and over the top as Brandon points out. The St Petersburg transmitter isnt great, but give it a try - I try and sync when outside using Flightradar so you can see when the like of emirates are heading north and off the northern coast of Russia.
Similarly on Gander 8891 USB, again earlier, you will get all the European flights from Japan and Korea heading north from Alaska. Examples are DHL715/717, JAL43/45, SWR161 nd also some Finnair that head direct north towards the pole.
