KPA500 - Fan Suggestion

[Richard Squire - HB9ANM]

If set to NOR, the KPA500 fan will switch to speed 1 at 50C, speed 2 at 55C etc.
If set to speed 1 manually, temperature rise will be slower and it will take longer to reach 55C or even 60C.
Then it cools down more quickly. Maybe not a bad idea to leave it at speed 1 all the time, the noise is hardly noticeable (my laptop fan is louder!). Especially if you are an RTTY contester! It will switch to the higher speeds automatically when required.

Yes. I have already placed a request with the Elecraft engineering team
for a firmware update that allows a more aggressive fan setting for
keydown modes (PSK, RTTY, JT65, etc.) .

That is what the user settable base fan levels are for in the KPA500
menu. When using data modes in high duty cycle environments, feel free
to set the lowest fan level to a higher value.
