It works the opposite of that way on moonbounce and 160 meters.

Moonbounce ops virtually all use heavy filters, because the 
background noise is a hiss. Same on 160 meters on quiet nights.

Try to use a narrow filter on QRN or "spikey" powerline noise, and 
the filter will ring the noise pulses out until you can't catch a "tone" 
between the pulses.
