Vladimir,

When I worked at Icom I once talked to a poor soul who had his rig 
inside of a box.
That boxed rig was sitting against an electrical outlet and near some 
metal that was grounded, maybe a heating register etc.
Lightning hit the power line, blew through the outlet, the box, his rig 
and to the grounded metal so he told me. Of course damaging the rig.
I said bury a nice thick plastic box in the back yard and next time it 
starts storming place your rigs in it.

Yes even a connected ground wire to the radio can or will cause you 
issues during a lightning storm.

  In eastern Washington they get some dust storms, those will do the 
same damage as lightning.
