Russian cellphone COMINT and antenna porn

On his business trip last month to St. Petersburg, my friend used a digital cellphone scanner that he used to successfully overhear the following conversation between a Russian Navy Warrant Officer and a distant civilian who seemed to be the insider on the Russian Navy ECM technology.

CIVILIAN: "...как лучше подавлять связь по Link-11?"
W. O. " ... возьми ... что-то типа КВ...Р-743 ... у нас на корабле передатчик...к нему УКВ "Утес" или Р-625 с формирователем помехи."
translation:

CIVILIAN: "...how to better jam communication on LINK-11?"
W. O. "...take...something like SW...R-743...we have a transmitter on our ship...together with USW "UTES" or R-625 with an interference generator."

Very important systems being mentioned here:
LINK-11 is USN's advanced digital communication system.


R-625 ("Пихта") is a USW station manufactured by the Musson factory in Sevastopol, Crimea, for simplex and duplex TTY/telephone-telegraph communications on naval and merchant ships. It looks like this:

UTES is a widely used rig which in its 3rd generation looks like this:

Here are the R-625's shipboard antennas - the single on an Akademik Ioffe "scientific" ship (this is the same ship that during 1980's in the name of underwater science killed whales by testing its roaring new Elac deep sonar, ADCP thermal current analyzer, a parametric and Echos multibeam sonar across North Atlantic all the way to Azores[USN Station Lajes]):

and the double from a Vishnya-type AGI (SSV).

Can you put it all together? The Russkies can.

Interesting post as for me. I'd like to read something more concerning this topic. The only thing this blog needs is some photos of any gadgets.
