I started running some 100% duty cycle operation with my KPA100 (PSK31 and Olivia). I was running 20 watts ... I'm not sure what power folks normally run in these modes (I'd be happy to get feedback on that), but, in any case, I was running well below the KPA100's 100 watt maximum. After around 90 seconds, the little fan on the KPA100 kicked in and really rev'ed up. The heat sink was, not surprisingly, quite warm to the touch.
So, considering I was running at 20 watts, would that level of heat be normal, i.e., was it actually no surprise that the fan kicked in? And is there any danger to the output transistors running key-down at the 20 watt level? Thanks for any tips or insight.
