"and the bottom line reading is very unstable - the power jumps randomly from 18W to 48W, so is the reading of wattmeter - it is also unstable. The returned power stays pretty low though. The meter bars on K3 also unstable. The SWR shows one bar and it is blinking fast. The RF is jumping randomly."
In November the power and SWR on my K3 were unstable 160M to 30M but perfect with a dummy load. After much give and take with the great Elecraft support staff, and even trying a new 10W PA unit, the problem turned out to be all my fault. I was using a long pair of wires from the manually tuned remote tuner across the apartment hooked to the straight key so I could fire up the rig at the tuner, then fine tune the tuner. The rig worked fine into a dummy load, but not when connected to an antenna. Turns out those 2 long wires were picking up a lot of RF and feeding it into the Key Jack causing the problem. What I should of done is test the rig with only the coax and power connected. That would have shown the problem right away.
