[Elecraft] K3 SHUTTING DOWN OPERATING JT65

[Colin]

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.
