1278 is audible here, but not very strong.

If the signal comes from курисово [Kurisovo], the distance is about ~400 km.
I assume the ARRT antenna is being used: 46.99341518966428, 30.896262571618276

The smaller cage antenna (шпренгельная антенна) collapsed betwenn March
2020 and July 2021, according to Google Earth pictures.
46.991058757749634, 30.889149353921177

Some smaller ones exist next to the transmitter building, but I don’t think that these are capable for high power broadcasts on MW.
