[Elecraft] K2 - Paddle & computer co-exsiatence

[Don Wilhelm]

Issac,

Be certain that auto-detect is turned on.  If it is off, behavior will 
be exactly as you describe.

Enter the menu for INP, press EDIT and then tap the DISPLAY button to 
toggle ADET - if you tap DISPLAY once and see ADET ON, you will know 
that it had been set to OFF,  Multiple taps of DISPLAY will toggle ADET 
on and off.
