Hi all,
Last night i thought a bit about noise cancelling on LF/VLF. Depending
on the band and distance and strength of the QRN, different settings for
a noise blanker are used, or optimal. Different rise times, treshold
levels and so on.
I thought about propagation changes and different shapes of QRN bursts
in the time domain, requiring different blanker settings.
Is it possible to program an 'intelligent' noise blanking system that is
evaluating the input spectrum, looking at the shape/type of a sferic and
automatically sets individual dynamic noise blanker parameters for each
burst?
Or do i miss something here?
Just a thought. I guess i'm not the first one who has this idea :-)
