[Elecraft] [KX3] PCB Layers

Hi Elecrafters Other posts refer to the KX3's PCBs as of the mutilayer type. Does it means double sided or are there also other layers inside the PCB? And if so, how many? 73 __ Elecraft mailing list Home:

Hello Pierre, No idea what's inside the KX3 but it's probably a multi-layer PCB. If you look very carefully at the edge of the board you can probably count the layers. Sometimes it helps if you moisten the edge...it makes it easier to see the layers. When I say moisten, that doesn't mean

given the chipset and technologies, its extraordinarily unlikely that the KX3 is not multi-layer. The interconnection density and pin arraignments on these chips virtually ensure that multilayer is the only way to build a compatible PCB. Even the lo-res video's posted todate, show component

Yes, the KX3's PC boards have 4 layers. This is more expensive but allows for much cleaner signal routing, including nearly unbroken internal ground and power planes. It would be essentially impossible to pack a 160-6 meter, state-of-the-art radio in to 1.5 pounds without this and other
