Yes. Neither level did much. No CW filters were installed. I even attempted to
play with the hardware adjustment. One could get more distortion, but not
better blanking. Strange. Interestingly, my IC-7410 blanker kills the fencer
pulses completely on it’s lowest level with NO distortion of strong signals.
Technology marches on.
