Classic Scanners that changed the hobby

We all love scanners, you would not be reading this if you didn’t. There are certain scanners that, much more than others, are so remarkable that they change the market or make a lasting impression on the hobby. Scanners that introduced new features, made other features popular or just were so darn good that they are beloved by the community will be discussed here.

If you have a favorite scanner that you think should be listed please let us know! The ones I discuss are scanners that I think helped define the market at the time and are real game changers. While some are obviously dated and obsolete today at the time they were introduced they really made a huge impact.

There were also a few real duds here and there. Bearcat once made a scanner that you inserted into an 8-track player. For those too young to know what that was, an 8-track player was used to listen to music recorded on magnetic tape held in large plastic cartridges in the days before cassette tapes, they were wildly popular in the 1970’s. This scanner was in the shape of one of these cartridges and had 4 crystal-controlled channels. It was a neat idea but worked poorly.

GRE Designs:

GRE built and designed many scanners for Radio Shack back in the day. Later they developed their own line in parallel with the Radio Shack line. Coincidentally both Radio Shack and GRE closed up operations for different reasons at about the same time and Whistler Group bought the GRE product line. Whistler continued to produce scanners for Radio Shack based on the Whistler designs for a short time and afterwards brought out their own line of WS and later the TRX scanners.

Radio Shack had a great advantage in that they had a huge retail infrastructure around the world and for years sold a wide range of scanners. While most were GRE built even Uniden made some of them.

PRO2004/5/6

The PRO2004 was introduced in 1986 and was probably the most revolutionary scanner of the day. It had 300 channels when 16 was considered average and 50 was considered remarkable. Its wide-open frequency coverage actually caused it to be recalled from stores to have the cellular frequencies blocked, this was easily defeated however, and the radio even had the proper spacing for them. They were coveted by the MilAir listener and helped create a large cottage industry for modifications and accessories. It spawned the PRO2005 and PRO2006 successors, similar in operation but in smaller cases with some other tweaks and additional memory.

PRO43

The PRO43 was introduced in the mid 1990’s and was the first handheld widely available that included the Mil Air band so were coveted by the airshow crowd. With 200 channels one could program in a ton of channels or do a search of the band. The tiny size made it easy to keep in a shirt pocket or camera bag.

PRO96

The PRO96 was the first P25 scanner that worked on the newer 9600 baud trunked systems, together with its mobile cousin, the PRO2096, one could now listen to these systems directly rather than in a conventional mode. It also provided a data source usable with software programs such as PRO96Com and has data detection modes that were well liked by radio enthusiasts.

PSR800/WS1080

The PSR800 was introduced in 2011, just before GRE went out of business. It was rebadged as the Whistler WS1080 soon thereafter and eventually morphed into the WS1088 and TRX-1 Mobile versions of the stillborn PSR900 became the Whistler WS1095, WS1098 and TRX-2. The PSR800 was the first scanner co work on Phase 2 P25 systems and was one of the first scanners with the on-board database and ZIP Code programming.

Uniden – Electra – Bearcat

Uniden Bearcat scanners originated with the Electra line back in the 1960’s and 70’s. After purchase by Uniden they retained the Bearcat branding and designs. Eventually Uniden bought the Regency brand and rebadged some existing Bearcat designs with Regency names.

Uniden became the biggest player in the market. Bearcat scanners have had great success with many groundbreaking designs over the decades. Here are just a few of the ones we think really made a huge difference:

BC-III

The BC-III was introduced in 1975 and was a VHF/UHF crystal scanner that was one of the most popular scanners of its day. It was unusual in that it allowed both UHF and VHF in the same radio in the days when that was not common. The speaker was huge and provided such good audio that years later, when the scanner itself was no longer useful, hobbyists would wire it up to be used as an external speaker for more modern scanners.

BC101

The BC101 was introduced in the mid 1970’s and was one of the earliest programmable scanners. It was programmed by setting the channel switches in a pattern for the specific frequency as listed in the programming guide. While kind of clunky, for the time it was revolutionary to be able to program a scanner without crystals and it had a huge 16 channel capacity.

BC210

The BC210 was introduced in 1977 and was Bearcat’s first direct entry programmable scanner. Imagine in the days when one would buy crystals for each channel, need programming combs or have to look up binary codes in a guide that they were now able to enter a frequency directly into a scanner. It was unheard of!

BC100                                                          

The BC100 was introduced in 1981 and was the one of first mainstream handheld programmable scanners. The first versions had a threaded antenna connector and later versions had a BNC. It used AA rechargeable batteries but they were internally mounted so a screwdriver was needed if you wanted to swap them out. It was a revolutionary handheld scanner that could be keyboard programmed without need of crystals, a new concept at the time.

BC235XLT/BC245XLT

The BC235XLT was introduced in the mid 1990’s and was the first TrunkTracker, it would scan Motorola trunked radio systems on 800 MHz. at the time. Before that one would have to enter the various channels into a scanner memory, lock out the current control channel and make a guess as to the actual users as there was no way to otherwise discriminate among them. The compact form and huge (for the time) capacity of up to 300 channels were huge selling points. The similar BC245XLT that came out a few years later added computer control and EDACS trunking to the mix.

BC780XLT

The BC780XLT was introduced in 2001 and changed the hobby more than almost any other scanner ever had. With 500 channels, the ability to track several formats of trunking, wide frequency coverage (including the Military air band) and great performance it remains a great scanner for many to this day. It was really the cream of the crop of the day.

BCD996/396 Series

The BCD996T was introduced in 2006 and replaced the BC780XLT as the flagship scanner, along with the portable version (BCD396T) it provided P25 reception and bullet proof reception along with up to 6000 channels of dynamically allocated memory. It spawned the BCD996XT and 996P2 mobiles and 396XT and 325P2 handhelds with similar features and carried on the Family arrangement of scanners where a handheld and mobile version were created. The 996/396 series introduced GPS enabled programming as well.

Home Patrol

The HomePatrol was introduced in 2010 and was the first ZIP Code enabled scanner. This truly revolutionized scanning and made it available to the masses who did not want to program a scanner, now they can just enter the ZIP Code to load the channels into the radio.

SDS100/200

The SDS100 handheld scanner was introduced in 2018, followed in 2019 with the mobile SDS200. These use the HomePatrol database but also provide excellent performance on digital simulcast systems. These systems have been the bane of scanners for as long as they have been around but finally a consumer scanner had good performance on them. With the color customizable display and ability to handle almost any type of radio system they will be the top of the heap for years to come.

Regency/RELM:

Regency, like Electra Bearcat, was an Indianapolis based scanner manufacturer that had some well-loved designs, especially in the 1970’s. Best known for its early crystal scanners, they had a large following. After many years they sold their scanner line to Uniden but a decade later came out with a new line of scanners under the RELM name that lasted only a couple years.

TMR-8H

The Regency TME-8H was an 8-channel VHF only crystal scanner from the late 1960’s. It was my first scanner, my dad had bought it for me so I could listen to him when he was working as a police officer in our hometown. We had the local channels at the time and with 8 channels I could hear all the local police and fire operations easily. 

ACTR20-6

The Regency ACTR20-6 was a 20-channel 6-band crystal-controlled scanner introduced in 1975. This was the days when an 8-channel scanner was a luxury, and one could spend more on crystals than on the scanner itself.

AOR

AOR is better known for high-end receivers rather than traditional scanners but some of their products made it to the mainstream scanner market. The AR8000 was the most notable but there were a few others that became popular. AOR receivers do not follow trunking so are pretty much relegated to the advanced hobbyist or specialty uses.

AR8000                                                       

The AOR AR-8000 was introduced in 1994 and was an early full-range and all-mode scanner with 1000 channels. It covered just about anything with antennas at the time, covering the entire shortwave, VHF and UHF bands, from 500 KHz. To 1900 MHz. It did most analog modes, including CW and SSB and was computer programmable and controllable. It was popular to use with the OptoElectronics Scout recording frequency counter and one could buy a special cable and battery door (that allowed the cable to plug into the radio) to connect the two devices. This allowed one to get a hit on the Scout and hear the traffic on the AR8000. While current scanners have the CloseCall or Spectrum Search these days this was revolutionary at the time. It was also known to have great sensitivity and worked well on the cell bands.

Other Brands:

There were many other popular brands like Robin, Midland, Cobra, RCA and others. Some were rebadges of radios made by Regency, Bearcat or GRE but many were (or are) their own designs. Many department stores of the day like Montgomery Wards, Sears and others also sold Regency or Bearcat scanners rebadged with the retailer’s name.

All those weird ports on the back of the scanner

Modern scanners have a plethora of various ports, jacks and sockets on them. Here is a look at some of them.

Taking a look at the rear panel of the BCD536HP scanner there are 6 different ports on it. From left to right they are:

  • BNC antenna jack
  • External Speaker Jack
  • USB Port (used for WiFi unit only on the 536)
  • GPS Serial Port
  • 3-pin power port
  • Coaxial power port

Other common ports on scanners include:

  • USB programming port
  • Record jack
  • Headphone jack
  • Various serial ports.

Let’s look at each port and what it is used for: (*Bonus! See below for an explanation of the weird hole smack in the middle…)

Antenna Jack:  Of course this is used to connect an antenna to the radio. Most scanners these days use BNC, the little push and turn job you see in the picture. Some handled scanners use the smaller SMA connector. Some older scanners had Motorola or even SO139 connectors and some had both an external connector and an internal threaded connector with a hole in the case to insert it.

External Speaker:  These are used to plug in an external speaker and are different than headphone jacks. Speaker Jacks do not limit the volume like a headphone jack will. When you plug in a speaker into the external speaker jack the inside speaker is disconnected.

Headphone Jack:  The Headphone jack has a limiting circuit to protect from overly loud sound that can damage your hearing. Otherwise it works much like the external speaker jack. Headphone jacks are usually in the front panel of desktop scanners while speaker jacks are usually on the rear. Handheld scanners usually just have a headphone jack on the top.

Record Jack:  The Record Jack allows one to pull audio from the scanner at a constant level that is not affected by the volume control. This is important when the radio is used as a source for recording or streaming. Some older RadioShack scanners and some current Uniden scanners have record jacks.

GPS Serial Port:  Unique to Uniden scanners, the DB-9 Serial port (male) is used mostly to connect a GPS receiver to allow location based scanning. It can also be used to program or control the scanner with the properly constructed cables. Do not confuse this with the female DB-9 port used for programming on older scanners like the BC780XLT or the BC898T

USB Programming port:  Most scanners these days use a USB-Mini port on the front or side to program and control the scanner. On many handheld scanners these ports are also used to charge the batteries and power the radio. On the BCD325P2 a special cable is used to connect a GPS to this port.

Other serial ports:  Some older scanners use different type serial ports. Older Unidens (like the “XT” series) use a unique 4-pin square connector for programming and connection of the RH-96 remote head. HP-1 and HP-2 scanners use that same port style for connecting to a GPS. Older design RadioShack/GRE/Whistler scanners use a jack that is just like a headphone jack for serial port connections.

Coaxial Power Port:  Most desktop/mobile scanners have a coaxial power port to provide 12 VDC to the scanner. There are 2 different jacks in common use. The majority of Uniden mobile and desktop scanners use a “Type M” male jack while most recent RadioShack, GRE and Whistler mobiles use a “Type T” female jack. Both use center-pin positive. Some older handheld scanners use smaller coaxial power ports but newer portable scanners usually use the USB port for charging and external power.

3-pin power port:  This is another unique to Uniden port, similar to the power port used on some of their CB products. On Uniden scanners there are the regular black and red wires for power and a third orange wire used to control the brightness of the display when connected to the lighting circuits of the car.

Discriminator Jack:  This is probably the most popular jack that doesn’t come on scanners. Discriminator audio is used to provide an unfiltered audio source mostly for data decoding. This type of decoding usually does not work from the record or speaker jacks due to the filtering circuitry in the radio. Scanners usually do not come with jacks for this but it is often added on by advanced scanner hobbyists to allow data decoding.

 

Bonus Round

See that threaded hole smack in the middle of the back panel in the picture at the top of the page? Most Uniden base/mobile scanners have that. It is used to allow a rear bracket to stabilize the radio under the dashboard. It is not mentioned in the owner’s manuals but is shown in the diagrams.

Update the firmware on your scanner!

Why would you want to update the firmware on your scanner, and how do you do it?
First, let’s explain WHAT firmware is. Firmware is the operating system of your radio, it works behind the scenes and tells the radio how to deal with things like keyboard inputs, frequencies, etc. Just like your computer or phone has an operating system (Like Windows 10, iOS etc.) scanners do too. Remember, scanners these days are miniature computers; they work much in the same way.

Firmware updates are released for a couple reasons. They either fix a problem or add/change features. Sometimes they do both. As an example, the BCD436HP’s most recent firmware update added the ability to add ProVoice and DMR digital protocols, before that firmware updates addressed an issue with clock settings.

When updating firmware one must follow ALL instructions CAREFULLY! You have the possibility of “bricking” your radio if you don’t do it right. This means that your $500 scanner may now be more useful as a brick than a radio… Follow the provided instructions to the letter and make sure that the program and firmware file you use is intended for your radio. The firmware for the PRO106 will not work on the WS1040!

Before trying to update the firmware on your radio make sure you have properly downloaded the firmware file itself as well as the installation program (if needed) BEFORE you start. If you do not have a replacement firmware file to install do not start the process since this erases the existing firmware to make the radio ready for the new version. No new version means no radio once you get going.

Some radios firmware updates are easier than others. The HomePatrol type radios use a program called Sentinel to check for new firmware versions and install them (easy, safe). Other Uniden scanners use a “Bearcat Version Updater” program to install a new update. GRE/RadioShack/Whistler scanners also use an application to install new firmware versions (nerve-wracking maybe).

What they all have in common is that they require a computer running Windows to update. (You can do it with a Mac running Windows with Parallels, Fusion, Bootcamp etc.) You also need the appropriate cable to connect from your computer to the radio. This is usually done via USB but some older radios use a Serial port.

Before updating your firmware make sure you have the following on hand:
• The radio you want to update
• The proper cable for your radio, along with the drivers already installed (if needed)
• The Firmware Updating program appropriate for your radio
• The actual firmware file itself (Imperative!)
• A strong sedative or plenty of alcohol to calm your nerves (optional)

Follow the instructions included with the firmware update TO THE LETTER. Make sure your radio and the computer can communicate properly. If you have programming software for your radio then read it first and save the programming file just in case you need to restore it to the radio. This also ensures that the radio and computer can communicate.

We also suggest that you check the RadioReference forum for your radio to see what other people’s experiences have been. Reading about someone else’s mistake is a lot easier than trying to fix your own.

Owners of PRO651 and PRO652 scanners that had tried to update their radios’ firmware versions had issues since no firmware updates were available until recently. Now one can download them and install them so previously bricked radios can be reincarnated.

ScannerMaster can update the firmware on many different models of scanners. Download the Hometown Programming Form for your radio and check the Firmware Update option if you would prefer our expert programmers to do this for you. We keep them heavily sedated all of the time already so their nerves are steady. Firmware Updates for “Zip Code Scanners” (HomePatrol, 436/536 and the TRX/WS1080/1088/1095/1098 series scanners) is included with the Setup and Optimize package already, it is an extra cost option for other scanners. If you aren’t sure call us and we will let you know.

Favorite Scanner: RS PRO-2004

Years ago in the mid and late 1980’s police scanners were pretty tame by today’s standards. 20 channels was the norm, 50 channel scanners were top of the line. Most scanners did not cover 800 MHz, the displays were small and hard to view.

Radio Shack surprised the scanning world in 1987 when it introduced the revolutionary PRO-2004 scanner.  Made by GRE (like most RS scanners at the time), it had 300 channels, totally unheard of at the time. People actually complained that there were too many channels available! Soon it was discovered that the memory could be easily expanded to allow 400 channels.

In addition the PRO-2004 had full coverage from 25-520 MHz. and 760-1300 MHz. This was also unheard of at the time. This was one of the first radios that covered the entire spectrum, including Military Air and more. Later versions of the PRO-2004 had the cellular bands removed from the radio.

The radio itself was pretty big and heavy. There was a lot of metal involved, the entire frame and case was made of steel, just the front panel was plastic. The metal case helped reduce outside interference sources. The radio soon developed a reputation for excellent sensitivity and image rejection and it was soon considered the top-of-the-heap scanner.

An entire cottage industry soon developed for modifications to the PRO-2004. It had plenty of room inside for additional boards and components. The radio had a diode matrix used to configure it for different areas and these uses were discovered in short order. Enterprising hobbyists created memory expansion cards. computer interfaces and data decoders to be installed to the radio.

The PRO-2004 spawned 2 successors, the PRO2005 and PRO2006. These were essentially identical to each other with minor updates to the 2006. The 2005/6 were identical in function and features to the 2004 but were in a smaller plastic case (although the interior case was steel).

Almost 30 years on and the PRO-2004/5/6 are still considered among the best scanners ever made. Many are still in daily use. The large channel capacity and wide coverage made them ideal for Military aircraft listening. While current scanners dwarf them in features and capacity the PRO-2004 made a tidal wave sized splash in the scanner hobby. Old-timers maintain fond memories of these scanners.

 

Firmware, Firmware, who needs Firmware?

OK, you have this whiz-bang multi-hundred dollar scanner sitting there and you want to make it much more better! You read about Firmware Updates but haven’t a clue what this means. Should you update the firmware on your scanner? If so how do I do it? What does it all mean? What is the meaning of all this? Can you do this for me?

First, let’s explain WHAT firmware is. Firmware is the operating system of your radio, it works behind the scenes and tells the radio how to deal with things like keyboard inputs, frequencies, etc. Just like your computer or phone has an operating system (Like Windows 10, iOS etc..) scanners do too.

When bad things happen to good scanners: Heap Errors

On certain Radio Shack, GRE and Whistler scanners, specifically the ones using Object Oriented programming, one can be beset with an error message that reads “Heap Error” along with some seemingly random text.

These are caused when the radio doesn’t know how to deal with an Object programmed into the memory, usually a Talkgroup (TGRP) not assigned to a  Trunked System (TSYS).

If you can get into the radio programming you should make sure ALL talkgroups entered as Objects are assigned to a Trunked System. This is pretty easy to do in ARC500 or other programs but a lot more difficult without software. These radios are hard enough to program manually let alone find orphaned TGRP objects.

When programming by hand be sure to associate every TGRP with a TSYS BEFORE saving it. When programming with software sort the TGRP list by TSYS and make sure all are assigned to a TSYS. If it says “New” for the TSYS then you need to change or delete the TGRP. Also check for duplicates in your list of TGRP’s. These can also cause errors.

If you don’t have software to program the radio and can’t get into the radio to edit the objects you may well have to reinitialize it and start all over. (Press 0, then 1, then enter during the startup screen.) While this will erase the radio it will get rid of the dreaded Heap Error. If you have software you can usually read the radio even if a Heap Error is present.

Object Oriented programming is used for the following scanners:

GRE: PSR310, PSR410, PSR500, PSR600

RadioShack: PRO-106, PRO-197, PRO-651, PRO-652

Whistler: WS-1040, WS-1065

Drivers? What are they and why do I need them?

If you have a scanner and a computer you will most likely want to use one with the other. Computer programs (like ARC products) are great for programming and controlling scanners.

Windows however tries to make life difficult for us and requires almost everything we connect to a computer to have “drivers”. Drivers are basically small programs that allow the computer and device to talk to each other, kind of like an interpreter.

If the stars are all aligned and all is well with the world the device driver will load automatically when you plug in the device. If not then you will have to install a driver to make it work.

We have a link here that helps scanner users get drivers and load them. This page also links to download pages for the drivers needed by many scanners.

Depending on the scanner you have the driver might be connected to the radio or to a separate cable. If your scanner has a standard USB port on it (such as a HomePatrol, a BCD996P2, BCD325P2 or some of the other newer model Uniden and Whistler scanners) then the driver goes to the radio itself.

If you have an older radio with a USB-serial adaptor cable, such as a BCD996XT, BCD396XT, PRO106, a PSR 500/600 etc. then the driver is matched to the cable (like the Uniden USB-1, or the blue, orange or black RadioShack/GRE/Whistler cables). Once the cable has the proper driver installed and a serial port (Comm-X) number assigned it can be used for any compatible radio with no further issues.

Some radios use an old fashioned serial port with a DB-9 connection, either on the radio or it’s programming cable. These require a serial port on the computer itself or the use of an USB-Serial adaptor. If you use a USB-Serial adaptor then the drivers connect to the adaptor.

The common denominator for all this is that the radio gets a “Com Port” number assigned. This will show up as “COM1” , “COM36” etc. Once this number is displayed in the Device Manager use that number in your programming software so the radio and program can communicate. This is kind of like a channel number, if the radio and computer are both set to the same Com Port number they can talk.

Com Port and communication issues are the biggest problem faced with users of software and scanners. Once you get the drivers loaded and the program set to the right com port then you can read and write to the radio all you want.

Some older USB-Serial adapters and cables will not work with some newer versions of Windows, or with 64-bit versions of Windows. Others require newer drivers to be downloaded and installed. Once installed the drivers should automatically be loaded each time you plug in the cable but sometimes Windows may change the com port number so if you have problems check the Device Manager to make sure.

Scanner Tip: Care and feeding of scanner batteries

If you use handheld scanners then you have to manage batteries. Most scanners come with or use rechargeable Nickel Metal Hydride cells, often abbreviated to Ni-MH. There are still some older Nickel Cadmium (“Ni-Cad”) cells still around. There is also a newer technology called Lithium Ion (“LI”). If you still use one of the older scanners with composite battery packs (like the BC250D or BC296D) these likely use or NiMH battery packs.

Current scanners almost always use “AA” sized batteries. AA Ni-MH batteries are very common these days and can be found almost anywhere and are also used in a wide variety of different applications. LI batteries are more expensive but are lighter in weight and provide longer life in many instances.

If you charge your batteries in the radio then remember that it is likely set up for Ni-MH. If you use Ni-Cad or LI cells then the charge times will be different. If your radio supports altering charge times then you could change it to match.

Whatever you do make sure that ALL the cells in the radio are the same! Do not mix different types of cells. Also make sure that you do not try to charge alkaline cells like Duracell or Ray-O-Vac’s! This is an easy way to blow things up and make nasty things happen. If you do this warranty will not cover you and the repairs are on you.

If you want to use rechargeable batteries that are different than the ones that came with the radio then consider a separate charger. This would allow you to manage 2 or 3 sets, one for current use and another for standby when the current ones are depleted and a third set in the charger. Make sure the charger you use is appropriate for the batteries you use.

What about Alkalines? Alkaline batteries, such as Duracell’s, Energizer or Ray-O-Vac brands, are great for scanners. You do need to make sure that you do not try to charge them. On many Uniden scanners there is a tiny switch inside the battery compartment that you can select Alkaline or Ni-MH. If you select Alkaline the radio will not attempt to charge batteries in the radio. If you have a RadioShack, GRE or Whistler handheld scanner then the yellow battery holder will charge your batteries when the radio is plugged into an outside power source, so do not use the yellow holder for alkalines. The black battery holder is used for alkaline batteries.

One other thing to consider is that rechargeable batteries produce a slightly lower voltage than alkaline ones do. Typically rechargeable cells produce 1.2 to 1.25 volts compared to 1.5 volts for alkalines at full charge. Usually this is not a problem; the extra quarter-volt per cell is not going to burn up your radio. Using higher voltage alkaline cells will allow the radio to run a bit longer before the battery warning starts.

Here is a little hint for users of later Uniden scanners: You can see how many volts your battery has at any time by pressing the rotary knob down while scanning. Make note of the voltage with fresh cells and the voltage when the battery warning starts. This will give you a good idea of when to expect the need to change or charge the batteries.

I always try to keep an extra set of batteries handy when I am out and about. Save those little battery boxes or use something to keep the batteries from shorting and bouncing around. I use a prescription bottle; larger ones are perfect for 3 or 4 AA’s! I can then toss that in the glove box. Just remember to take off the label so the world doesn’t find out what meds you take. Do they make a pill that will cure a scanner addiction?

Selecting Your First Radio Scanner

Scanner FrequenciesBuying your first radio scanner requires understanding the differences between radio systems and scanner frequencies. While you do not need to know exactly how each radio system works, you do need to know which ones are used in your area. It is never safe to assume, just because you live in a small town, your needs will be met with a basic analog scanner. You would be surprised by how many smaller communities have state-of-the-art radio systems, requiring either trunking or digital scanners to listen to two-way radio communications.

  1. Find out what radio systems are used in your town. The first step to selecting a radio scanner is to conduct a little research and find out what radio systems fire, police, and other agencies use for communications. The easiest way to do this is to use our free scanner comparison tool. All you have to do is choose your desired listening range and enter in your zip code. Next, select the counties you want to monitor on your new police scanner to see important information about the radio systems used.
  2. Compare scanner radios based compatible with your location. Our scanner comparison tool also shows you several different models of hand-held portable, mobile, and desktop scanners that will pick up scanner frequencies in your location. The key thing to remember is that it is not what features and options are on the scanner, but the type of radio systems used in your area. Every location is different, and the police scanner has to be matched to the radio systems.
  3. Consider what agencies you want to monitor. Most people buy a scanner to listen to fire, police, and emergency medical responder transmissions. A small percentage of people also use their scanner radios to listen to other government agencies, railroad communications, campus police, and racer/pit crew communications at live NASCAR racing events. Choose a scanner based on the scanner frequencies you want to hear.
  4. Radio systems used in your town can change. Police, fire, emergency responders, and other agencies do upgrade radio systems from time to time. Keep this in mind when selecting a compatible scanner. For instance, if your city currently uses a basic analog radio system, they might decide to upgrade it to a trunking system in the future. Unless you have a scanner capable of picking up both analog and trunking communications, you would no longer be able to monitor any frequencies moved to the new system. You may want to check with your city or county planning commission to find out if there are any plans for upgrading the radio system in the near future before purchasing your new police scanner.
  5. Support options for the scanner. If you know you are going to need help programming and updating the scanners firmware, it is recommended you look at models that can be plugged into a computer. This way, in most cases, you are able to receive remote desktop scanner support without having to send in your scanner any time you need help.
