Jack;
You can always tell RTTY types. They like all caps… ;-)
But they are cool ops too!
The KPA500 Faults at 90 degrees C. The highest fan level kicks in at 80 degrees.
And for those who were wondering, the fan first turns on when the measured
temperature gets to 50 degrees C.
As my friend KK7P noted a few days ago, the fan will run much less in the antarctic in June,
and much more in the Sahara about the same time of year. It really depends on the environment
it (and you) are in as to how much it will run, and how long it takes to get to a high fan level.
Enjoy your Elecraft devices. And don’t worry about pushing the KPA500 too much. It has
proven that it can take it, contest after contest.
73!
