Buddy/Mike, further to my earlier email the current on receive is
actually 1.05A as measured on a digital multimeter and not 5A as
indicated on the PSU analogue meter.
Of course this doesn't solve the immediate problem.

Mike, I am experiencing a similar thing. I had a session on FT8 a few
days ago and my K3 shut down completely, in fact it blew a 20A fuse on
my alternate 20A PSU but just shuts down on my 40A supply.
One thing I notice is that it appears to be drawing nearly 5 Amps on
receive which is excessive and one occasion while I was testing actually
shut down on receive.
It isn't the DC lead as I have replaced that with a factory supplied item.
I'm still working on it but unless the experts in this group have any
ideas I will attempt to re-invent the wheel.

Hi Buddy
I can thing of 2 things. Overheating .. not likely since usually the RF
section shut downs.
RF getting into the power supply. Grounding might not make a difference.
RF Chokes on the power supply DC cord might help.
Oh, the 3rd thing, Is your power supply up to the task? Might it be
failing? Throw a volt meter on it.

i am using wsjt-x software for jt65 using my k3. after operating for
approximately 2 hours today, i answered a cq, and after 30 seconds the k3
shut down completely. i waited a few minutes and changed antennas. the k3
powered up, and i tried again. same result, shutdown after 30 seconds of
transmitting. my power is set to 30 watts, and i am using a kat500 with
both antennas.
any suggestions, any questions?
