A few questions on using the Squelch function, please.
a. et’s say I have a peak where the top of the peak is -80 db.
The noise floor is about -120 db
I select squelch, and want the audio to be active only
if there is actually a signal present.
I thought I would then set the slider value to -55 db (Green bar) as an experiment.
thinking I should hear nothing. But, the audio still comes thru.
Sometimes. But not all the time. Doesn’t appear consistent
Am I using squelch correctly ? How should it be set up and used ?
b. And, any way of having a Cursor (a horiz line perhaps) to visually
show the level that has been set ?
