A jammer in the yard?
We've been hearing a bad, high-pitched squeak on the balcony for days. 24 hours a day. I can't open the balcony peacefully. We also have a cat that doesn't want to set foot on the balcony anymore. I suspect this is a jammer. I was about to call the clerk's office. Will this bring anything? Is there any way I can do anything? I don't even know which party it was from...there are lots of balconies around the courtyard. Can be anyone. We were terrified. Help!
The signal jammer works without making any sound. The beeps could be any fan bearing failure or something else.
