I came home from work and turned on the K3 and the P3 and then switched to the
CW zone of the 40 meter band. The VFO was about 7.009 as left from my last
visit yesterday. I turned the VFO up just a tiny bit and this strong, like S9+
broadband noise came through. Funny because I remember
Next time you see something like this, take a look at the VCO control
voltage (PLL1 or PLL2) using the DISP meter function. If the K3 goes
out of lock, it puts out all sorts of garbage audio and the PLL (VCO)
voltage moves around randomly.
I've had this happen on 5 MHz when working with

I have seen the same kind of thing twice, only over roughly twice the
frequency range you describe. However on both occasions the only solution
was to do a recalibration of the VCO from the config menu. Simply turning
the K3/P3 off and on did nothing in my case. I recall that on both
I noticed that the width of this noise seemed to be the width of the pass band
since when I changed modes (CW, USB, etc.) the width of the affected frequency
spread changed. It also changed when I adjusted the filter width.
