Re: [KX3] KX3 Heat Sink Improved and Now Shipping

[Edward R Cole]

Ordered my KX3 Elecraft Heat sink, yesterday.

I already use the Cooler-KX heat sink made by VE7FMN so will be
interesting to see how the two compare and how the combo work
together.  I will repeat temp compensation procedure and do over
frequency drift testing for
1.  Elecraft heat sink, only
2.  Combo
I already have measurements of the VE7FMN heat sink:

Check VE7FMN website for updated prices (link from my webpage).

Ed, can you mount the combo? As I recall I had to
remove the original plate on my KX3 to mount
Fred's heat sink.

This aspect of the new Elecraft approach "A
high-performance, die-cut thermal gasket is used
between the rear panel and heat sink to ensure
excellent heat transfer" is most interesting.

Your comparisons of the Cooler-KX vs. the new
Elecraft heat sink will be very interesting!

Ed,

There should be no need to re-do the extended temperature compensation procedure, regardless of which heat sink you're using. This procedure creates a table of temperature-vs.-frequency correction values. They apply identically to any heat sink; the only thing that is changing is the rate at which temperature increases.

73,
