Description

This option is just what you will need to upgrade your already equipped KX2 that has my Side KX end panels and cover, for those needing additional heat dissipation.

In collaboration with Howard Hoyt at ProAudio Engineering, this heat-sink PAE-Kx22 was designed to allow extended transmit time at the KX2’s full-power settings, which is especially useful while using digital modes.

No passive heat sink can allow unlimited key-down time on the KX2,

however, the heat-sink for the KX2 has been engineered using thermal CAD

modeling techniques as well as KX2 transmit testing for maximum

performance with a minimum of increase in overall size. This is the

heat-sink of choice for those who want enhanced transmit time and

still retain low weight and size, and it is the absolute maximum footprint with minimum mass.

This allows the KX2 user to retain the portability which is the prime reason Elecraft

designed the KX2. With this in mind it has been engineered to be

fully compatible with the KX2 Cover and Mounting Cradle.

capabilities, please visit: ProAudio Engineering

****UPDATE***** Elecraft has had to make a change some components on the right end of the KX2 where you will be mounting the right end panel. Please read the new updated installation manual HERE for all of the changes found on KX2’s regarding their recent modifications. I along with Howard Hoyte of ProAudio Engineering have updated this manual and we now offer 2 versions of the PAE KX22 end panel, one has the thermal pads, and one does not

Original KX2’s from serial number 0016 through 5417 will use a PAE KX22 with thermal pads.

KX2’s with serial numbers 5417-5441 have a very delicate and different version and will require special handling to be done by either Pro Audio Engineering or Elecraft certified repair of Dave Wallaghen for upgraded installation due to this delicate version.

If your radio was produced after serial number 5441 (roughly since May 2025) you do not need the thermal pads, please put a note in the order section so I can send the correct version of the end panel. These newer and the older V1 radios are a straightforward install following this updated installation manual.

Please keep in mind Elecraft does not warranty issues from third party products installed on their radios. As well any installation of third party products is at the risk of the individual doing the installation. Side KX and GemsProducts.com are not held responsible for any issues caused by the installation of these products.

For both instruction sheets and detailed videos on how to install these, see the INSTALLATION tab.
