Right. Any sort of device with a switching power supply will create noise, AND most noise blankers are likely to be ineffective, because it's not impulse noise.

This search for a better noise blanker may be misguided. The solution to most noise issues is to kill it at the source.

FWIW -- the best noise reduction I have ever heard (and it is amazingly good) is in NR0V's control software for ANAN radios. Warren is the inventor/developer of the Pure Signal algorithm. I visited his QTH (only a few miles from mine) a year or two ago and he demonstrated it to me.  Warren's software might work on your noise.
