Hi - I've gone through five scanners and was wondering if someone can
recommend one before I run out of money. On all of these scanners, I
try and set the squelch so that it skips unused frequencies. However,
when a used frequency is found, the squelch chops out most of the
audio. If I turn the squelch all the way down, I can hear all of the
audio. I try and use the least amount of squelch possible, but it
still chops the audio so you can't understand anything. Needles to
say, I'm ticked off that devices could be designed so poorly.

Thanks in advance.

Can you tell us what scanners you've used? I use the Pro 96, Pro97, and
PSR 500. Also have used several different Bearcat, Uniden, and Radio Shack
models and haven't found the squelch too difficult to regulate.

I assume you've turned the squelch all the way up and then backed it slowly
down until it just allows the radio to scan thru the frequencies? That's
how I fine tune mine. If I have an additional freq. or two that overloads
and stops on that setting I back off the squelch just slightly to get those
freqs/channels to scan. So far I don't feel I'm missing anything and
everything seems to come in loud and clear.

Am I missing anything? Is this what you've done so far without success?

I suspect you've hit the nail on the head Sarah. Operator error springs to
mind.

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.

The only thing that makes sense is either you are getting a lot of bad
scanners, or you don't understand that squelch isn't perfect and very
weak signals will pop in and out, especially if it's not set correctly.

The latter is my guess. I'm not trying to be mean or anything, but with
nearly 45 years of listening on tunable receivers and scanners, the
squelch circuit was/is basically a non issue with all but the two I
mentioned before, and one of those was bad out of the box. A replacement
worked fine. The other I could have fixed, but I just sold it instead.

The scheme you mention for designing a squelch circuit has already been
done, in many scanners. It works, but not much better than the "WWII"
technology in others radios.

I have talked to a lot of people about scanners over the years, and can
count squelch issues on the fingers of both hands.

Can you give me a model, or what is the name of the feature for the
smarter squelch so I can look for it?

With the way it works now, I have to manually turn the squelch right
off and, yes, the signal is bit weak and snowy, but I can hear
everything perfectly. If I turn up the squelch a bit, all I hear is
BA__ DE__ NO__ LE__, etc. All I need is the feature that
automatically does what I have to do manually.

Sounds like you are trying to use a carrier(AM) or noise(FM) operated
squelch as an audio squelch - different animals.

Google "audio squelch" for details - it is indeed a simple digital device;
and when done properly will ignore all except human voice (or some signal
which approximates the syllabic rate of human voice).

Carrier and noise squelch have been around for generations - I have used
them in scanners, ham transceivers and professional equipment for over 50
years without the problems you are having. Aviation, public safety, Ham
radio and other mass users of squelch don't have the problems you are
encountering.

Audio squelch has been used for a quarter century or so, especially for SSB,
in professional equipment and has started to become more common in consumer
level stuff in the last ten years or so.

If you really want a voice squelch Google "SSB Squelch" the first hit will
give you a source, and there are others in the 53,000 Google hits.

Lol good one. Don't even know how to use squelch, yet you are going to
design your own scanner.
Please post back with the results.

I'm leaning that way too Rob especially considering he said he's had the
