It seems that Army MW 810 kHz is not on air anymore. The radio station of the Ukrainian army has been testing several times since the beginning of December on 810 kHz 10 kW.
In an answer to Mauno Ritola the station says: “So, it was test signal…. Now we don’t have medium frequency like 810(( But you can hear us on the satellite and online if you want))) I am sorry “
