Incident Details
On January 19, 2016, at approximately 22:20 UTC, an incident occurred in the Warsaw Flight Information Region (EPWW) involving an Embraer 170 aircraft. An air traffic controller from GAT ACC reported a recurring issue with strong reception interference on frequency 125.45 MHz. The interference originated from a receiver located at KRK, which was one of three receivers for the nationwide frequency. This receiver was causing strong interference and had to be deactivated. As a result, the controller faced difficulties in communicating with aircraft crews at low altitudes, who were nearly inaudible. The controller was forced to rely solely on the KRK radio station for all communications. The interference was not detectable on the air navigation service provider's own receivers. The event was reported to the Office of Electronic Communications (UKE).
Probable Cause
The probable cause of the incident was not established.
