[TenTec] TVI 95% Shield

[Charles Harpole]

In my "real world" TVI is the norm, not the exception.  I have lived and operated in the usa (at all power levels) at seven locations in six states and had some degree of TVI in all those places.  In TX, my Mexican neighbor called to say, "I hear you thru my phone, and IT IS HUNG UP."  Later, I handled some Mex. City earthquake traffic for her ("relatives are ok") and she liked me after that.  I also bought her a better telephone set.

I also modulated the flourscent lights in the kitchen, spoke strongly thru my son's stereo, and made the other neighbor's remote control airplane radio lights blink.  The best place I lived had all elect wires buried and all used cable tv (I did not need cable tv because I rcvd all sig for it that I needed via a leaky pedistal in my back yard).  RF is RF and it loves to excite everything it can, including the atoms in ur eyeballs.  73
