[Elecraft] K3 suffers from amnesia

[Udo Langenohl - DK5YA]

Gentleman,

it doesn't work unfortunately. PTT is always "OFF - OFF" when both K3 
are shutdown. No matter if the computer is running prior to the K3 or 
vice versa.

I asked another ham friend nearby with two upgraded K3's, the same 
issue. Could anybody else please try this?
