You'll find that sometimes you need to turn on the preamp for the noise
blanker to "do its stuff" even though the noise sounds VERY loud! I've not
dug inside to see what's happening to the signal levels but on 80 meters
there are a couple of lamp dimmers that can blow the cans off of my head
<G>. Turning on the NB at either level does nothing, but add the preamp and
the noise disappears.

Darrell, Greg, Darwin,
Great wisdom this reflector brings ... (Yoda, Starwars VII).
Tested the noisblanker rubbing a screwdriver across the first RF amp Q21.
Yep, makes a difference. Now waiting for a nice thunderstorm or some static
rain :-)
Thanks all.
Okay, what's next? Ah yes, the DSP module...
