This sounds like a PL259 on one or the other end that is incorrectly dressed and soldered. I would guess something wrong in the PL259 that attaches to the K3. Before you throw the K3 in the drink, use a different piece of coax. All it takes is a very small gap that does not show up on an analyzer, but is arced across by 100 watts, or a short that makes contact when you bend it to get to the K3, or yada, yada, yada.
Mechanical problems with coax, plugs, jumpers, cords and adapters, etc. are by far the most common problem with ham setups. 73, Guy.
