Can you provide a recording of this noise? Not sure what I am looking
for, but I don't think I have it here.
A few more notes about the noise blanker. My hardware noise blanker
was installed about two weeks ago - and frankly - it took me awhile
to find a noise that the DSP noise blanker didn't address on its own
to really see if the hardware noise blanker was up to snuff.
Somehow - one evening, my own electric fence started making some
noise. Rather than a normal click (which the DSP NB can deal with
just using signals within the passband of the roofing filter), it is
more like a short duration buzz. While the DSP NB did bring it down
in strength - the hardware NB totally took it out.
Currently, the firmware is setup that when you press the NB button,
both of the blankers are engaged. When you hold and press the NB
button - you can adjust each blanker (the VFO A know adjusts the
DSP one and the VFO B knob adjusts the hardware one). The changes
happen as you turn the knobs - so you can hear the differences in
real time. Each NB has 21 settings + the off position.
