Hallo Jacek

the nearest NDB is SA,  474,5kHz

the drift is  +-5Hz

  ERP  valued to  10..30mW

i think,  no hazard

It is not yet time for the BNetzA

      look for local NDB's near this frequency. if none is found, then
      maybe you could say that it might drift to NPR (488kHz, Airport at
      Tomaszow Mazowiecki). if BNetzA needs to have a reason to
