Oilfield Campaign and NDBs

[shake307]

So, I am just starting the Oilfield Campaign and ran into a confusing thing, at least for me.  Maykop-Khanskaya NDBs for the outer and inner markers are the same frequency.  Outers are both 289 and inners are both 591.  Attached is the screenshot of them.  I see they both have a suffix of a letter or two.  What does that mean and how do I get the Mi-8 to distinguish between the two?  Thanks for any help.

Only one pair of NDB's will be active at any one time, which pair depends on the active runway i.e. ATC/wind direction.

The different letter suffix are their morse ID's, so *you* the pilot can confirm the correct runway/beacon is active i.e.

 

• 289kHz RWY 22 outer marker = RK = ".-.  -.-"

• 289kHz RWY 04 outer marker = DG = "-..  --."

 

From a game play perspective, mission winds are setup so ATC has the correct runway/NBD's active, so it's not something you'll usually need to worry about outside of dynamic weather or mission making (DCS's 2.5.x ATC can desync the active runway and NDB for light (1-3 knots) headwinds i.e. ATC will say to use RWY 04 but activates the NDB's for RWY 22).
