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

if it's drifting, then it might drift onto an NDB  frequency. and that would be an aviation hazard.

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 investigate, then maybe the possibility of interference to a foreign airport might be enough
