So IMHO, the unit should be called a "noise blanker".
My ancient FT-1000 had a noise blanker that worked very well ... unless
there were other radio signals on nearly frequencies. Think: contests.
In that case, it predictably folded like a lawn chair. Has anyone
tried one of these during a contest? I would be very surprised if it
would work under those conditions.
