[Elecraft] KIO2 install and volt meter problem

[JEAN-FRANCOIS MENARD]

Hi,

You should look around U3 on the control board, U3 maybe defective,  
Also look at the voltage chart in the manual and check for R9 and R10  
on the control board. Also check that you do not change the position  
of jumper P7 to "EXT" position instead of "INT".
