KPA1500 fans

[Elecraft mailing list]

I have all of the KPA1500 fan mods and firmware upgrades and they make
the amplifier so much quieter.?? Good job, Elecraft.

What I would like to see, however, is a firmware /option /to exhibit the
following tendency.

Minimum fan speed at 0.?? When the amp detects a PTT, then the fan speed
would increase to fan level 1 and remain that way for a period of time
after PTT detection has ceased (perhaps 10 - 15 seconds?). After that
delay time it would go back to fan speed 0.?? Of course, temperature
sensing would increase fan speed regardless of the PTT sense.

If this has been discussed before, I missed it.?? If it's currently
available then I missed it again.

Awaiting my K4.?? I hate waiting!

73,

Is there a fan mod other than a firmware upgrade?
