[Elecraft] K3: E 0400Cd ERR DSE

[James Sarte]

Was in the middle of a 10m QSO tonight, and all of sudden no power.  Got
this message on the LCD:

 

E 0400Cd ERR DSE

 

Don't have a manual in front of me, so I'm not able to check at the moment.
This is the first time I've come across such an error in the time I've had
my K3.

 

I was running about 5 watts.  Antenna SWR was 1.2:1.  Firmware is 3.10

 

Any thoughts?  I'm going to try to upgrade to 3.11 tonight to see if this
happens again.

 

73,
