[Elecraft] K3 SHUTDOWN

[Lu Romero]

Mike:

Check your power connections to the K3, especially the
Anderson power poles.  Sometimes they get "corroded" and
dont make good connection. Or they just get loose. This will
cause a momentary drop below 11 volts, and the K3 will shut
down.

Also, make sure your power supply has enough voltage
regulation and doesnt sag below 11v.  When I was using a
Astron 20, I had this issue in RTTY.  Changing to an Astron
35 cured it after I increased the voltage output to give me
14.1 volts indicated AT THE RADIO (on the FP display) when
in RX.  The PS saggs to 13.1 at full 100W output. The old PS
sagged below 11v on RTTY.

I wager to say that one of the above issues is causing your
problem. After the above checks, I have never had this
problem again.

This morning while playing in the RTTY 'test, I answered a
CQ by sending 
my call nine times (3 bursts of 3). 100W power.  The antenna
is at 1.0:1 
SWR.

*CLICK* and the K3 powered off. I wasn't watching it, so
didn't see any 
error message. Vague I know, but it's all I have. Any
thoughts?
