One of my readers (thank you, SL) pointed out that someone identified the location of the Voronezh-M radar at Mishelevka and posted a photo of the radar there.

Construction of the radar was first reported in December 2010. It appears to be located in front of the site of the Daryal-U transmitter building (which may have no longer be there - the reciever was demolished in June 2011). In March 2012, the minister of defense said that the Voronezh-M radar in Mishelevka is undergoing trials.
