[Elecraft] K2 freeze at startup... need advice

[Jean-François Ménard]

It seems that something let my K2 stuck in TX mode. I removed all  
module and put appropriate jumpers (unmod kit). Still in TX when  
powered ON. I checked this using my DL2 dummy load with my  
multimeter.... I always have output power !!

Could it be a defective KEY jack that is jammed? I have nothing  
plugged......
