Hi,

Just for the record, my standard setting is:

DSP t2-5
IF MED3

This is really effective for my power line noise. There are cases where the noise starts to come back when there are strong (SSB) signals in the passband but normally it remains blanked even then.

Hi,

according to preview discussion on noise blanker of K3 I decided to
write few words also as I have lot of experiences with that I guess...
My antennas are really close to electric fence (just few metres)
so the pulses on all bands with K3 are over S9+20dB !

A few points as the results of my tests and final settings
which I am using on my K3 untill now.

1. Only the combination of the dsp and IF is able to kill the el.fence
pulses
2. dsp/t1-7 does not help in my case with any combination of IF values
3. IF NAR/MED/WID does not help if values are lower than 4...
4. dsp/t2-5,6,7 or t3-5,6,7 values are really agressive and it
suppressing
the pulses effectively if its in combination with IF setting MED or WID
with
higher than 4 values.
