1 GE84PLN First select fragment GE84. In Russia (RUS), select one recorded assignment, SOCHI KRAS, 106.1 MHz. Make a frequency search at that site between 88.0-91.0 MHz.

The maximum nuisance field gives an indication of the Eu at site. The complete analysis also involves calculating caused interference. (if too high frequency is unusable)

Usually you don’t have to worry about interference caused to stations of your own Administration.
According to 4.3.7.1 you should verify if any stations of other Administrations have an Eu increase of 0.5 dB or more.

n/c : Eu is not calculated (n/c) for the case Nuisance FS is 10dB (user selectable) below Eu Ref
Eu Ref* : Eu calculated at the time the assignment entered the Plan
Diff > 0.5 dB; if this is a station from another Administration, they can object according to 4.3.7.1
* n/a means Eu Ref does not exist for modifications under treatment
