It will do that if the K3 is in transmit mode but with no power coming
out. The P3 auto-scales the modulation display amplitude, so if there
is no signal it jacks the gain way up and you see quantized noise.
The next version of P3 firmware will limit the maximum gain so you don't
see so much noise in that situation.

My P3TXMON scope display is not performing as it should, while I am talking
in SSB mode.
Frequently the display will go to a straight line with vertical signals that
are very narrow.
It looks almost like it is switching to a very wide span or the time base is
changing frequency.
This will continue until I stop transmitting, then it will be ok for a
while, then does it again.
A friend is also experiencing this same bug on his P3TXMON.
Anyone experiencing this same thing?
