re. K3/K3S noise blanker performance greatly enhanced (at my QTH) -- need testers

[John G3PQA]

Thanks Wayne, the software blanking improvement on CW using FL1 13kHz filter set to 400Hz is remarkable because not only does it suppress strong electric fence pulses here for the first time in years but also cleans up the NB function when FL1 is enabled. I used the 13kHz filter because it was in my K3. DSP 2-3 or 3-3, IF Blanker OFF.
The main improvement is on the DSP blanker, the hardware blanker remains only mildly effective on strong electric fence pulses and is little use if any with FL1.
Some overload on strong signals as expected because of wide roofing filter. Setting the bandwidth to activate either my 500 and 200 filter each side degrades NB performance to previous.
I will try with a 6kHz filter in due course.

That answered a question I took off list, will my 12 KHz filter work,
looks like I will be testing this...
