You probably won’t hear anything but the normal channel marker operation (like I’m listening to right now) on it unless STHF and Russia orders a total mobilization of its forces.
There appear to be a number of people around the world who monitor UVB-76. There have been periods of altered behavior observed in recent years; these are noted in several blogs.
The most recent of these appears to be in 2013. I wasn’t able to find any reports more recent than that.
Many think it transmits information to spies in the field (look up one time pads) The strange thing is that the buzzing sound seems to be from a machine placed up against the open microphone, instead of internally within the radio itself.
Lots of conspiracy theories about UVB-76, but it is most likely a World-Wide fixed radio net for Russian forces. We have several of the same, though they don’t broadcast much anymore with direct satellite and digital coms. Ham operators occasionally catch the US stations broadcasting coded messages.
It has been said that it could be the radio station for the rumored Soviet/Russian “Dead Hand” doomsday system, but we won’t likely know that until the balloon goes up. Then, we’ll all be too busy running to care.
Any folks notice significant activity from any other European numbers stations?
Tried to DF several numbers stations in the early ‘80s from time-to-time. Damndest thing. Using some of the largest antenna fields in the world and a very large (geographically) DF net, bearings from each site could never come close to pinpointing some of these sites.
The ‘buzzer’ was just freaking annoying.
