[Elecraft] K3/100 suddenly shut down on FT8 TX

[Yoshida Akira]

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
