I wonder where he's at, when he's not surfing googlegroups. ;-)

Okay, so far we have this Ali Baba who wants to set off a communications jammer with a cheap Chinese LCD clock alarm...hmmmm, so the jammer and clock are to be pre-placed at the location of the receiver to be disabled at about the time something else is going on Ali doesn't want the people at the receiver to know about.

Maybe just an elaborate practical joke to be played on someone such as a dispatcher?

Maybe or maybe not. The aspect of remote activation on a schedule fits a railway scenario pretty well. The plan could be to defeat a CBTC ( communications based train control) system attempting to automatically bring a train to a stop under any one of a multitude of hazardous and emergency circumstances such as broken track or block occupied status. This would fit a driverless system pretty well, maybe a subway system somewhere.

sir what u said i cant understand?

The act of jamming radio communications is illegal everywhere except in certain very narrowly defined circumstances. If you were covered by those circumstances then you would, presumably, already have legitimate access to the necessary technical data. If you don't then it's a good bet that you aren't.
