Re: K3 Woes -- Problem Solved!!

[David Inger-2]

I recently sent a message to the group regarding the fact that my K3 would
shut off at power levels over +/-50 watts.  I tried two different power
supplies, made up new power cables and even reset the radio.  The problem
remained.  Several group members offered suggestions, some of which I had
already tried, and some of which I hadn't.  I was ready to sent the radio
back to Elecraft for service, since I am going on vacation in about a week
(poor me; I am being "forced" to go to Hawaii for two weeks) and don't
really have time to dig into the radio.
 
On a whim, I borrowed a power supply from a friend (a Powerwerx SS-30DV);
problem solved!  With a little troubleshootting, it was quite apparent that
there was output voltage regulation problems with both of my two supplies.
One was about 5 years old; the other about two.
 
I never would have assumed that both supplies would have "gone south" at the
same time; so much for assumptions!  I like this outcome rather than have to
send the radio in for servicing.  Alls well that ends well...

Wouldn't viewing the K3's voltage display as power was increased have
helped in solving this more quickly?
