[Elecraft] K3 High Level Digital noise

[wa9fvp]

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.
