KPA1500 new software 1.87

[NK6A-Don Minkoff]

I just went from my 1.62 rev to 1.87 and something changed.  My fan use
to come on at 60 deg and now comes on at 50 and off at 40.

I need to go back and try and reload the older version.  I don't think
this is correct.

Anyone else run across this?

The firmware release notes seem to support what you are seeing:

Changed temperatures for fan speeds:
- On 160 thru 10 meters, fans increase speed at 50, 70, 80, 87, and 95 degrees, and slow at 40, 55, 75, 81, and 88 degrees.
- On 6 meters the fans increase speed at 40, 50, 65, 80, and 90 degrees and slow at 35, 41, 51, 66, and 81 degrees.
- New serial command ^FP0; can be entered in the KPA1500 Utility command tester to revert to previous fan profile, which sped up at 60, 70, 78, 85, and 90 degrees and slowed at 57, 67, 75, 82, and 87 degrees.  ^FP1; selects the "new" fan speed profile, ^FP0 selects the "old" fan speed profile.

This is as intended. The release notes describe this.

The intent is to use higher fan speeds less often by starting a bit lower.

John,

I just went thru this and reverted back to the original fan profile with the
^FP0 command using the KPA 1500 utility.  What is not mentioned in the
release notes is that after you execute this command, you must power cycle
the KPA 1500.  After that you will have the new firmware with the old fan
profile.
