Here’s some resources that I’ve found on the radio waves about Ukraine.

• I’m listening to the BBC on 5875 right now (0041z or 1942 eastern), focused on Ukraine issues

  I also heard they will broadcast on 7475, 9470, 9490, 9940 but nothing heard.
• Earlier today from 14z (0900 eastern) I heard the BBC on 15735, same focus

• Supposedly at 12z (0700 eastern) Ukraine Radio will be broadcast in English on 5010 and/or 6005.

• This is a list of Russian military frequencies. Those have been silent for me or encrypted junk.
