Hello All. While the Cooler KX may not be necessary for each KX3, it is never the less available to every KX3 operator for whom this amazing radio has become their base or even only rig.
Increasing among us do not have access to amplifiers, do not have access to resonant antennas, do not even have a dedicated ham shack. Compromised antennas, and improvised portable operations, emergency deployments, restrictive HOAs, crowded noisy living spaces, these are becoming normal rather than unusual ham operating scenarios. The KX3 meets the needs created by these circumstances.
I cannot say that the creators of the rig envisioned what their baby would grow up to become, but the assembly literature has now been revised to suggest that while the radio may be capable of 10 watts output, it is in fact intended that it do so under specific conditions.
We are pushing the rigs capabilities to new boundaries. That is what hams have done in the past out of a thirst for knowledge, it is what we do now out of necessity to be able to stay active.
The Cooler KX addresses the well documented overheating of the KX3 when it is deployed on the ragged edge of its capabilities. When a KX3 is your favorite rig, when it is your only rig, QRP is not a luxury; it is a fact of life. When you have no amplifier, and the band conditions are changing, and your antenna is ‘tuned’ the radio warms up. When every watt that you paid for counts to seal the QSO deal, then the Cooler KX helps to get the job done, without any power consumed, without any station noise added. It simply and passively sucks the heat out of the radio, which can only be good for all of the components, not just the PAs.
You don’t have to buy a Cooler KX, but if you want one I will surely build one for you. Fred, VE7FMN
