K1 Noise blanker

Joel

I recently assembled a K1 noise blanker. It doesn't seem to reduce my power line noise any. Any one have any suggestions or comments?

Joel,

The K1 (and K2) noise blanker is designed to work on impulse noise -
those noises with a fast rise time like automotive ignition noise or
distant lightning clashes.
It will not eliminate slow rising noises like power line noise.

The K3 Noise Blankers are very effective against line noise FYI with no
buckshoting off to the sides of your passband due to close by stations.
   Most rigs I have used are not this good and are not worth having in
