KX2 modification

[IK4EWX]

I own KX2 serial number 749. I see that on higher serieal numbers KX2
Elecraft have introduced a modifications for reducing spurious on tx (and
improve thermal dissipations it seem to me). What do you think about it? Is
itreally a good think to pay for the modification or can I make without it?
Many thanks.
Ian IK4EWX

Ian,

Since your KX2 is less than SN 866, I would recommend that you install
it.  See
https://ftp.elecraft.com/KX2/Mod%20Notes%20Alerts/E740304%20Inst,%20mod%20kit%20KX2,%20harm%20supp,%20rev%20B.pdf.

Anyone who orders a replacement or aftermarket end panel (no matter the
serial number) should also install this change.

Hi all,

We have had several inquiries as to whether our Pro Audio Engineering
Kx22 Heatsink for the KX2 is compatible with the Harmonic Reduction Mod
kit, Elecraft p/n KX2MDKTHS.  The good news is since discussing the
issue with Elecraft two years ago we have been supplying the Kx22
Heatsink with the Harmonic Reduction Mod already installed.  With the
proper application of the thermal transfer compound we include this
approach results in thermal performance better than either stock
configuration.
