I'm really surprised by all these negative comments about K3 NB. Mine
has been very effective on electric fences (I have one!) and power line
noise.
Try this from 5 years ago:-
http://www.g3tct.co.uk/GB3ANG_processing.mp3
[you'll hear first the GB3ANG beacon on 70MHz (tropo, 607km) in ssb
bandwidth (2.3kHz) with no noise blanking. There's bad power line noise.
At 6.7seconds in, the noise blanker is switched on (set at dsp t2-6,
IF narrow 3). At 21.4secs in, the mode is switched to cw - the audio
tone remains the same, and the bandwidth changes to 900Hz. At 30.5secs
in, the APF is switched on until 56.4secs. At 61.5secs we revert to usb
mode and at 68.3secs, the noise blanker is turned off.]
