[Elecraft] carrying cases and ESD

[Stuart Rohre]

Hi,
Indeed, vibration in mobile transport creates triboelectricity, a charge
build up by friction of wires insulations against conductors.  It could be
not the foam of the box, (which usually is grey or black indicating carbon
content) but the wiring inside the radio.

It is always good practice to short a cable before connecting it to other
electronics to remove any residual charge.
