NDB Moskva-Domodedovo (*DM/DO) :

Russian NDBs change their frequencies and idents quite often - it is quite hard to keep track on it. So NDBs with call 'DM' appear in the Moscow region with the years on these 4 frequencies: 320 / 370 / 581 / 659 kHz, and at least it seems to be 2 different locations, one is approx 55 26 N / 37 50 E (Domodedovo), the other is approx 55 36 N / 38 02 E (Ramenskoye).
