Hi Ken, list, I've done some pretty serious thermal studies of the KX3 (http://proaudioeng.com/wp-content/uploads/2014/03/PAE-Kx31-chart1.jpg). I looked that the "Go Box" concept a while ago and agree; The problem with the idea is that the KX3 uses the case back for all it's PA heatsinking. In the KX3 case design the front-half of the clamshell case is almost completely thermally disconnected from the case back (only the thumbscrew area is in contact), and cannot remove PA heat by conduction. In the Go Box concept the front panel is the only thing exposed to ambient air flow. If the back part of the case was to be sealed in a closed cavity or encased in foam, heat build-up would be inevitable. The Go Box idea may not kill the KX3's performance (drift, thermal limitations) if the KX3 is only used as a receiver or very low duty-cycle operation. Of course, one could put a fan in the box, but here we go again, killing the KX3's most hard-won and fantastic attributes: low power consumptio n, no moving parts and no acoustic noise.

How about heat dissipation if the intent is to operate the radio in the box and encased in foam? Ken - K0PP On Jun 6, 2014 5:50 AM, "Jeff Herr"<[email protected]> wrote:
