I also have the sub and a full compliment of 8 pole filters. The narrowest is the 250 and the next up is the 1K. I am wondering how I, without all those varieties of test gear can determine if indeed there is a significant offset that exists with the 8 pole filters in my K3 and if it exists to know how much it + or - it is. Of course I would need to be able to test both main & sub to know what the particulars are so I could properly adjust the ofset settings. I do find using diversity is much better for CW copy than without.
