Steve,

I was thinking it might have been you.  I often snap on the DSP instead of
the noise blanker but as is the case with so many pulse noise blanking
circuits, super loud signals up and down the band trigger the noise level up
and down.  I figured that would be a thing of the past in a more expensive
radio
these days but it reminds me of the good old days when I would snap on the
noise blanker in my Ten Tec Triton One.  It helps, in a weird sort of a way,
by copying a signal several KHz up the band without tuning the receiver up
there when listening to the dits and daws of the line noise bleeping off and
on, haw.

Phil.
