Question about Radio Shack Pro-2018 Scanner

1 Answer

I am also new to radio scanning

My brother & I bought my mother a scanner for Christmas. I read the manual, programmed the four stations that she wants, and have it set to scan. I watch the scanning as it occurs in the display screen. The problem is that when it picks up a signal, it is impossible to understand.

The manual only says one little bit about what to do with "squelch". I don't know what the word "squelch" even means. I have it not set so that it's not hissing (all the way counter-clockwise), but not quite halfway toward "maximum", either. When a voice comes on we run to the scanner to attempt to adjust the volume and/or the squelch, but can't seem to get anything that is intelligible.

Please help with how to adjust the audio ... and please explain what "squelch" means. Thank you!

    Thank you ... I thought this post was forgotten. We are located in a suburban area. My mother had an old scanner (with a whopping four channels) that worked great in the same location. She wanted a new one, so we got it for her. She has a list of the locally used frequencies that I programmed into the new scanner (same exact frequencies she had in the old one). I then checked a couple of different websites that have online lists of frequencies used by the kinds of services that she wants to listen to (local police and fire, etc.) The websites had the same channels that she gave me from her old (ancient) list as well as others that I also programmed in.

    Thank you for your explanation of squelch.

Hi, you do not mention where you are located, but my first guess is that you are trying to listen to some freq's that are not compatable with your scanner. The squelch you use to quiet the white noise, so when someone keys their mic the squelch opens easy and allows you to hear them. The scanner you have is a standard FM analog style scanner. Nowdays there is also digital and encripted, trunktracking, and more. None of the different styles are compatable. On my scanners at home I run an external antenna to pull in a greater range. Our local area still runs the standard FM radios. If you respond back with some info, I might be able to narrow the problem down further.
Thank you,,, Mechanic

    Maybe it's just me, but I think the older units used to work better. I now use a 100 ch. and to get the same range, I had to add an external antenna. It allows me to hear the car to car activity that does not go thru the repeater. Puts my range at about 25-30 miles. If I'd go up higher on the tower, the range would go up also,,, good luck with it,,, Mechanic

Will not scan properly


I suppose you are trying to scan the channels by hand, If I'm not mistaken this model can also be hooked up to the pc.

Manual pages 55 and forward are on scanning, I suppose you have been throught those.

I't must be a simple setting wrong somewhere.

If you haven't yet programmed it for your area, you won't get much - if any - reception. Most Radio Shack stores will program the scanner for you, or at least give you some valuable assistance in programming it. They can also sell you programming software to simplify the task. IMHO the Butel software available from is the best on the market, and it will let you download virtually every frequency and system in your area directly to the scanner. I also suggest that you visit for a comprehensive database of active freqs and systems in your area, and a lot of other useful scanning information.

If it just seems to be "stuck" on static, you probably need to adjust the Squelch. Try turning the squelch down until the static stops.
If you haven't programmed any frequencies into the banks, scanning won't do anything. Press "Func" and "Scan" to perform a Search. This way, if you find a frequency with a lot of chatter, you can program it into a bank for scanning later.
The easiest thing to do is to find frequencies for your local police, fire, etc. on the internet & program them into the various banks on the scanner.
