Excellent Marinos. Thats what I wanted to say! I am using my K2 as my main rig due to it's excellent features except when I must switch due to city noise. I do, of course, have a variable gain preamp that I built for my 80/160 phased loops that in turn feeds my K2 so I have plenty of rf at the blanker input.and the scope confirms it. There is nothing wrong with the blanking pulse widths. This low level city hash is simply not triggering the blanking mv due to other blanker problems. With my old Kenwood TS-140S and other rigs I typically see a 3 S unit drop in a S4 city noise floor and the weak ones jump out of it. We 160m noise eaters would buy a good RF noise blanker even if the box was twice the size of the K2.
