[Elecraft] KPA100 oscillation during IARU Reg 1 Field Day

[Jukka Tarvainen]

I took closer look into K2 and KPA100. Can't find any source of smoke. Only
thing that looks like it could give some smell are the thermal pads of final
transistors. The black stuff has partly stuck or melt into heatsink. Pads
seem to be aluminium and they are clear where that "blackness" has gone
away. I will do more testing tomorrow.
