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.
