I am constantly amazed with the 'power' of noise blanker built in GSDR: it is
able to 'eradicate' plasma TV junk like no other radio I've
operated. It really makes the difference between decoding weak
signals (and not).
Here is just another
example showing the waterfall 'background junk' with filter off,
and then on.
Needless to say,
KK4RDI was no decode at all until NB was turned on.
