The DSP and IF noise blanking are distinct and operate in series when both are on.
IF NB shuts off the IF for a very short time when spike is detected. The timing and width of that depends on the IF setting. The DSP NB does various things in the number soup after the analog to digital converter. The NB button toggles either or both IF DSP NB depending if either type is OFF in the settings. DSP 2-7 and IF narrow 4 on at the same time take out my particular 160m power buzz that comes and goes around here. Good for four s-units of suppression which gets us back down to the regular nighttime S4 cr*p. Same radio at other locations takes other settings to handle THEIR particular noise. 73, Guy K2AV On Tuesday, November 10, 2015, Oliver Dröse <[email protected]> wrote: > Might it be you still have the DSP NB on, Jim?
