[Elecraft] How to use the PX3's noise blanker

[Wayne Burdick]

Hi John,

When you turn the NB on, you should see an "NB" icon in the upper-right corner. 

The menu also has a setting for NB level, which you may need to adjust. In my case I've assigned both NB and NB level to FN switches so I can change the settings very quickly. 

With the NB turned on, you will observe one of three things in the PX3's displayed spectra:

1. No change (because any noise that's present is too low in amplitude to activate the blanker)

2. A reduction in "jumping" of the display (because the NB is having a beneficial effect on the noise)

3. An *increase* in "jumping" of the display (because the NB level is set too aggressively)

Some experimentation with settings may be required. Note that the KX3 also has an NB function, with a similar level adjustment, but noise that affects the audible output of the KX3 may not affect the visual output of the PX3 and vice-versa. Thus they are independent settings.
