[Spooks] Russian military on 5492kHz?

[Jim Kalogeros-Chattan]

Heard a CW transmission on 5472 which brought back memories of 70s and 80s. Is this Russian military?  If so, they seem to be using procedures from 40+ years ago:

1) First group AAAAA
2) Final group date/group count, which, if I remember rightly, was ABWGDEVZIK substituting for 0123456789
