Manchester car park lock hack leads to horn-blare hoo-ha

Mr_Pitiful

We encountered this problem

There was a large carpark near one of our installations and an empty building nearby

The criminals had setup a jammer on 433.92Mhz to operate between 5pm & 10pm weekdays & all weekend

We operate monitoring equipment on that frequency and every day between 5 & 10pm and the weekend, we couldn't recieve any signals from the equipment.

I ended up sitting outside with a portable radio scanner for 2 evenings to figure it out, we contacted the police and the problem went away the next day.
