Hi Tom,
You'll get a lot of opinions on noise blankers, I suspect :)
Here's my 2 cents: The K3's combination of two noise blankers -- one
at the 1st IF and one at the DSP -- can work wonders on all sorts of
noise. But it's especially good with power-line noise (loads of that
at my QTH).
The K3 blankers have a considerable range of adjustability of both the
blanking threshold with seven steps, and the blanking pulse width with
three steps, with independent settings for hardware blanking and dsp
blanking. Hopefully, you can find a setting that will work without
excess
