Usually this kind of thing is external to the K3, very often mechanical. Often happens when something external is rearranged. Remove *everything* connected to the K3 except the power and a dummy load. Make sure the power voltage is normal. See what you get then. If you still have noise, put an AC voltmeter across the DC power leads. Come back with the results.
73, Guy K2AV --------------------- While transmitting, my K3 developed a high level noise. During SSB with the mic level set at 25, there's 30 watts output power. It sounds like digital noise. It stops when the mic level is set to zero. There no microphone connected and I just down loaded the latest firmware but that didn't help. It happens on all bands and while transmitting into Bird 200 watt attenuating load. With an additional 20db of attenuation, and a total of 50 db, I checked the TX output on my spectrum analyzer. The spectrum is clean at all TX levels.
