The Priyom.org website is reporting that the Russian Buzzer is not transmitted from Kerro anymore, new military marker on 4525 USB.
"The Russian military network The Buzzer on 4625 kHz is not transmitted from the Kerro transmitter site ("Irtysh") anymore. It seems that the Russians are reverting to their old structure, when the frequency 4625 kHz was only used for the Moscow Military District. At present, The Buzzer appears to be broadcast only from the 69th Communication Hub in Naro Fominsk.
"A new military marker, similar to The Buzzer, The Pip, The Squeaky Wheel and S5292, was discovered on the frequency 4525 kHz, starting in August. However, no messages/signals have been caught from that frequency yet."
