I landed at Aalborg in northern Denmark a couple of weeks ago. It's a combined military and civilian field, and it has an impressively large radar rotating at ground level not far from the taxiway.
As I taxied past it my Garmin 196 was stunned into silence and had to be powered off and back on once away from the radar before it would come to life again.
I was also getting a distinct 'thump' sound in my noise-cancelling headsets every time the radar rotated past me.
Reminds me of the time I worked on computers in a port-side building. One day they started to go bonkers every few seconds. Took a little while to connect this with the Navy ship which had come to visit and tied up at the nearby wharf with the radar still operating.
