The Russian Navy are quite active during this deployment in Morse Code. For the most part they use international callsigns and a list of frequencies assigned and agreed by the International Telegraph Union.
Obviously the near impossible part is linking the callsign to the exact vessel. That aside they do on occasion send weather and sea state reports containing a lat and long.
I noted callsign RAL46 sending the following on 12464 Khz at 1234 GMT today.
RAL46 BT 715 19 21 1614 715 BT FM RAL46
21121 99367 70096 41498 80207 10160 40310 53010 70211 884// 22233 20801 302// 41002 21014 BT AR
From the message the second and third groups contain the lat long. That puts the ship off the southwest of Portugal.

Group 6 = 10160 will be the temperature plus 16
I believe that group 11 indicates heading and speed? 22233 222 degrees at 3.3 knots?
Probably an indication that the Kuznetsov Task Group, or elements of, are shortly to enter the Mediterranean and meet up with the Frigate Ladny?
Black Sea Fleet (BSF) frigate Ladny heading for the Mediterranean Sea has called at French Navy's main naval base Toulon before joining Russian Navy carrier group comprising ships of Northern and Baltic fleets. ....
The Russian warship will replenish water and fuel supplies in Toulon and on Dec 17 lay a course for the rendezvous point of Russian Navy carrier group in the western part of the Mediterranean.
