Hi all
Maybe my problem looks solved. Referring to suggestions I checked all
coax cables.
I found a cable with bad poor contact at both end plugs. K3 see very
high SWR instantaneously
and it shout down.
I have not seen the problem for several hours since bad cable was replaced.
Thanks again for suggestions.

Hi all
Thanks for more suggestions, however I am not happy.
I noticed this a several times yesterday when transmitting FT8 with 50W.
I checked DX cable and connectors. It looks OK. I look at voltage,
current and PA Temp
with internal meter. I do not notice any significant jump just before
shut down.
It is better for me to send K3/100 to JA dealer who checked
everything, sometimes
replaced parts before.
BTW: my K3/100 s/n 00060 arrived on 2007/12 I still like this radio
best.
Thanks

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.

Hi all
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 ?
