You assume correctly. As I mentioned... I try to use as little
squelch as possible.
I did have one scanner that worked not too bad (a Pro 92) that died.
I'm looking for another one with no success.
I've since bought several on Ebay that are total crap. A pro 2051, a
pro 2055, and a few others that I don't recall.
I suppose that it could be just bad luck that I got duds.
I've designed a lot of digital and microprocessor electronics in my
day, and what kills me is that it would be so simple and inexpensive
to digitally process the audio signal to see if there is a signal
present. The computer could then just cut-out the squelch at that
point. Rather it seems that they just use some old crappy analogue
squelch circuit that chops out the audio (especially on weak
signals). I'm seriously considering making my own scanner unless
somebody knows of a good one that doesn't use WWII technology.
