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.
