When transmitting FT8, it suddenly shut down (power OFF) Of course I do not touch
any button. It looks as if I push Power button.

After a while I push Power button and it turns power ON.  Maybe Power button problem ???

I’m curious.  When transmitting, why would one press the POWER button on the 
radio other than to turn the radio off?

Something I am missing here.

Hi all

Thanks for suggestions. All look OK to me.

Power supply is Powerwerx ss-30DV. I do not use Powerpole connector
in the front panel, instead use terminal in the back panel.

I use this power supply for another TRX also and have never noticed the problem.

I have never seen this for many years, however I recently noticed twice
when transmitting FT8 with 100W. No alarm and error message.
When I simply push POWER button in front panel then it turns ON again.

PA temp, DC voltage and DC current looks good. I do not believe RFI
cause this problem.

Any idea ?
