Fan question on K3

w5sum
First, I'm having no trouble with my K3 ( which was delivered to me a week before they announced the S grrrrrrr).
I have NEVER felt or heard the fans running! My K3 ( nick named Buster ) is warm to the touch, never HOT, but still even in a 48 hour contest I've never been aware of them running!
Either buster don't need to cool off or something is wrong?
Anyone have an opinion on this?

I have not heard the fans on my k3 since 2008...:-)
Oh, and I don't expect to in the future.
If you are unsure, place your fingers close and feel the breeze.

The manual describes a "Fan test procedure" to run the fans at each speed to make sure they are working. You can also use this to set the fans to a speed if you are working in a warm room or outdoors in sun and running high power and find the radio unusually hot.

Ronnie,

You can manually select a minimum fan speed if desired. See the CONFIG:KPA3 menu entry.

Re: Fan question on K3

Gary Smith-2
In reply to this post by Elecraft mailing list
To adjust for a specific fan speed, this
is as written in the manual:

------
Fan Speed

The K3S/100 includes two large, quiet
fans. Fan speeds are normally selected
automatically, but you can manually select
a minimum fan speed if desired. See the
CONFIG:KPA3 menu entry.
--------

I never have found the K3 to get hot,
ever. Nothing like the hot my old Drake
TR-7 used to get.

That said, I'm a bugger for driving with
low power so I often have the amp on in
case there's some DX I want to go for and
don't want to wait for the warm up period.
So I'll set the drive from the K3 (& now
the K3s), at 2-5 watts or so and with the
amp being QSK, it works perfectly and if I
want to go QRP, I'm already there.

I could just drive the radio at 100W which
is what most of us do but I like doing it
this way. Besides, I don't like turning
the amp on & off multiple times throughout
the day, I understand that isn't nice to
the tubes over the course of years. So
this way I have a cool rig, no issues with
distortion, and the amp is always ready to
go. Only downside is a higher noise level
in the shack but to that end, I almost
always wear the Bose QC-15 and they make
the noise go away.

73,

Gary

If you prefer to do the calculation in your head, I find it easier to think of the formula to convert C to F as:

Deg. C = (deg. Fahrenheit - 32) X 5/9

or, if you want to convert the other way:

Deg. F = (9/5 x Deg. C) + 32

Hope this helps.
