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 techniques we used.
