[Elecraft] KDSP2 - Now What Have I Done?

[Ken Alexander]

That did it Don!  Many thanks!

Somehow, my first filter setting was:  C1 1.35 .75

I don't know how I managed to do that!  It requires more button presses than I thought I made!  Anyway, it's fine now and I'll proceed more carefully from here on.

Thanks again!

Ken, VE3HLS
