An evening monitoring Russian groundforce military signals

I take a trip out to the remote barn in the Peak District to monitor some military radio signals. I wanted to find out if there's any increased radio activity on the Russian military ground force frequencies. I get to hear some counter activity being transmitted on the frequency known as the Buzzer. I'm not sure whether the music/noises being played is radio trolling by amateurs or something more strategic. If you want to find out a little more about these frequencies and how to monitor military radio signals, this link is useful: https://priyom.org/military-stations/russia#ground-forces
