Grigoriopol transmissions.
Refer to

621 kHz: An old 150 kW transmitter originally installed at some other station somewhere in the USSR. Uses the 77 metres mast (also a standard type, if I recall correct called Aksion). On air only Mon-Fri between 7:00 and 8:18 local time. Programming is Radio 1 plyus, no separate feed required because Grigoriopol transmits this around the clock on FM anyway. It had been stated that the frequency was offered to TWR as substitute for 999 kHz. Until now no such transmissions appeared, so either there was no such offer or TWR refused it.

999 kHz: One of the Buran transmitter blocks from 1971, set aside as separate transmitter by breaking up an original two-block unit. The original ARRT-257 antenna collapsed due to icing in 2000, the comparatively small 150 metres antenna is the replacement. Another picture of this antenna accompanies a posting that obviously comes from someone in the know, informing that the Radio Rossii transmission, started on April 5, is run with 1000 kW.
It has been noted also in “regular” DX circles that this relay has a rather extraordinary delay of almost twenty seconds, making one first wonder if there are no news at the hour. Ingest is in all likelyhood from satellite, who knows through what a cascade of encoders and multiplexers.

1413 kHz: The former 234 kHz transmitter, run in a synchronized network with Sankt Petersburg (Krasny Bor) and Arkhangelsk (Koskovo), probably closed already in the moment the USSR ceased to exist. It used a 350 metres mast, brought down in 1997 exactly the same way than earlier the Konstantynów mast in Poland. The 1413 kHz now uses the four mast antenna, which is a type called Kvadrat with switchable pattern (not to be confused with fixed SV2+2 systems). Since 3 March 2014 the transmitter is on air around the clock with Vesti FM, originally set up as 500 kW and eastern beam, there is no reason to assume that any changes have been made in the meantime.

1548 kHz: The only MW outlet still running in its original configuration, with the Zarya antenna designed for skywave transmissions into the Balkans region. The TWR transmissions on this frequency continue, usually with the first item starting out of the blue after some time of open carrier, I assume from local file playout. (In the USSR days this transmitter was during daytime used on other frequencies, like 549 kHz, with the Kvadrat antenna, a constellation rather common for such foreign service installations. The most remarkable case existed for some time at Bolshakovo: Daytime 171 kHz, evenings 1143 kHz.)

11530 kHz: At present the only shortwave frequency in operation from Grigoriopol, carrying Dengê Welat. A picture of one of the shortwave transmitters accompanied a report about Radio Rossii on 999 kHz, so beware of possible confusion here.

Radio Rossii: This was indeed the child of Yeltsin, launched in 1991 on the frequencies of the culture program of Allunion Radio. Its shortwave service included up to the very end one frequency for Central/Western Europe, which could hint at possible considerations for using 999 kHz now.

Vesti FM: I can only leave it to others to determine the hardliner stronghold, even if it is part of VGTRK at all since another good possible candidate would be Perviy Kanal (the former Tsentralnoye Televideniye, which Yeltsin did not kill like Allunion Radio). Anyway it started in 2008, as the name already indicates on FM. VGTRK had no frequencies outside Moscow: No problem, Radio Kultura, which they had launched only in 2004, had to leave FM again (I understand it’s now just a cheap offspring of the Rossiya-K TV channel).

No licence: These transmissions have no licence from Chisinau just like the transmissions from Taiwan have no licence from Beijing. And certain maps with arrows out of Tiraspol have swiftly been retracted. Let’s leave it at that.
