Last month's column contains an erroneous set of Google Earth coordinates for the Russian 69th Communications unit, one of several suspected UVB-76/Buzzer/S28 locations.
This one seemed to elude my proofreading. It's a bit embarrassing, really. The correct location is 60.231100° N, 30.273928° E. The one in the column, 60.231100° N by 60.231100° E, actually is still in Russia, but it's way out in the Ural Mountains somewhere. The correct location is north of St. Petersburg.
Sorry about that. Appropriate corrections have been made in the local files here.
