[Spooks] C

[Utility World (Hugh Stegman)]

Probably navigation since they transmit most often during naval exercises or
major operations of some sort.  C is Moscow.  These beacons are all over the
Russian Federation and Ukraine, and that's a big area to be all over.

The clusters tend to be spaced 0.1 kHz.  C is supposed to be on 10872 CW.
It's right between S and A.  It doesn't do much good on 10972 all by its
lonesome.

The latest list I have on the 10 MHz cluster is:

10871.7  D  Odessa
10871.8  P  Kaliningrad
10871.9  S  Arkhangelsk
10872.0  C  Moscow
10872.1  A  Baku
10872.2  F  Vladivostok
10872.3  K  Petropavlovsk-Kamchatskiy
10872.4  M  Magadan

"A" seems to have moved recently.
