Using a two-way radio as a scanner

One of the more common question we get here at the opulent ScannerMaster Palace is how do I program this (Brand X) radio to my local systems. Usually it is one of those off-shore $40 two-way radio with unpronounceable names that are flooding the market on eBay and in stores.

The basic answer is that you don’t. These radios are intended as Ham radios and are basically toys. Some can be made to receive on VHF and UHF conventional analog channels and even talk on them.  This is not a good thing. First off the build quality on these things is poor. They are designed not for performance but for cheapness. If the radio breaks it usually cannot be repaired.

If your area still uses VHF or UHF analog channels then these might be able to be used to receive your local channels but they cannot do any type of digital or trunked system.

These cheap radios are not ideal for most monitoring anyway. They lack the features scanner buyers have come to expect such as banks, scanlists or quick-keys. They also usually do not support other typical scanner features like CloseCall, Fire tone out, easy field programming etc. They often do not work on aircraft, either civilian or military.

For not much more than you will pay for one of these cheap toys you can get a decent basic scanner like the BC125AT or WS1010 that will run rings around  them with the feature sets.  Our basic scanners start out at under $100 and have way more features than these junk toys.

Basic Troubleshooting – How to fix a silent scanner

So your fancy scanner no longer works. Is it the scanner itself or did your local agencies move to new channels? Today we will discuss ways to find out.

The first thing I tell callers when they say their scanner is dead is to try the local weather channels. Almost everyone is in range of one of the National Weather Service radio stations on 162.400 thru 162.550. If you try each of the 7 channels (listed below) and nothing is heard then there may well be something wrong with the radio. If you have another scanner or weather radio handy try that one. If the other radio works then there is likely something wrong with the first radio.

Here are the weather frequencies that you can check to see if your scanner is working properly:

  • 162.4000
  • 162.4250
  • 162.4500
  • 162.4750
  • 162.5000
  • 162.5250
  • 162.5500

If the weather channel works on your scanner then we should look to programming. If the radio worked before but no longer hears the local police, fire or other agencies you used to listen to then they may have changed frequencies. Several states have recently updated their wide-area radio systems, if you live in Ohio, Indiana or South Carolina there is a great possibility that this is what occurred. Alternately, some agencies have switched to existing regional radio systems such as these states or those in Illinois, Missouri, Wisconsin, Michigan Colorado, Louisiana and Mississippi among others.

The best thing to do is check the RadioReference.com database and forums. If you recently lost your target there is likely someone else who has also. I had a caller the other day from northern Arizona say his police department disappeared, he listened to them over the weekend and then on Monday they were gone. We found that they had just switched to a new P25 digital system. While it was not yet listed in the RadioReference database it was being discussed in the RadioReference forums for Arizona.

If all this fails and you cannot find the target anywhere by searches with the scanner there are still a couple more tricks. Remember that public safety communications systems are expensive. They don’t go out and buy them on a whim. Purchases of that size usually must be approved by the local boards, City Council, County Supervisors etc. Look at these board’s websites for meeting minutes and agenda items. This is all public information and most places these days post them to the web. You can sometimes find all kinds of interesting information on the systems, sometimes even complete technical details, frequencies and talkgroup information get put up there!

Check with your local officers and administrators. While often they might not be technically savvy they might know that “we switched to the County system” or something. Also look for the type of radio they are carrying or have installed in the vehicle. That can sometimes point to the radio system type they are using.

Once you find out what system they are using and the frequencies etc. reprogram or replace your scanner to match.

Questions? We have answers!

Here are a few of the common questions we get here at ScannerMaster’s World Headquarters as well as the answers we provide. If your question isn’t listed please call us and ask.

Q: Do you have scanners that will allow me to hear Encrypted/Scrambled communications?

A: Nope! There are 2 reasons why we don’t sell scanners that work on encrypted channels. First of all it is illegal. Our people like sleeping in their own beds at night and not on cots at the county jail. Second, even if it were legal the technology just isn’t there to break modern encryption, especially on a device sold to the public.

Q: Do you sell scanners that can hear cell phones?

A: Nope, sorry, for the same reasons we do not sell encryption capable scanners, it is illegal and impractical. Years ago one could clip a diode and open certain scanners for the old analog cell phones but those days are long past.

Q: Can you tell me the frequency for my hometown police department?

A: Sure we can. You can also find the freqs at www.radioreference.com

Q: Are you guys the same guys at RadioReference? Broadcastify? Uniden? Whistler?

A: No, we are ScannerMaster. We are friends with these other companies and do business with them but we are all separate companies. We sell products from Uniden, Whistler and others but if you need support beyond what we are authorized to do we will refer you to the right place. We can often answer a quick question here and there about these places but we have no access to their files.

Q: Can you fix my scanner?

A: We do offer a programming service and programmed replacement SD Cards for ZIP Code scanners but we do not do repairs or sell internal parts. Newer scanners should be sent to Uniden or Whistler for authorized repairs, One great source for older scanners repairs and parts is G&G Communications, they can be reached at 585-768-8151 or http://www.gcomradio.com

Q: Can my scanner be upgraded to DMR/ProVoice/NXDN?

A: Well, that depends on the scanner you have. Here is a list of the scanners that can be upgraded for these modes. Some of these can change in the future so be sure to check back! If you have an older scanner then it cannot be upgraded for these modes.

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.

FRS/GMRS/MURS/CB: The Personal Radio Services

Anyone can use one of several types of two-way radios, most of which do not require a license. From something the kids can play with to serious business uses there are a bunch of different types of varying quality and usefulness. These are called CB, FRS, MURS and GMRS. Only GMRS requires a license, the others do not. Each of the four services have different intended functions.

  • FRS: Family Radio Service (low power, short range, intended for families and individuals)
  • GMRS: General Mobile Radio Service (high power, longer range, intended for families)
  • MURS: Multiple Use Radio Service (mid-power, medium range, intended for business)
  • CB: Citizen’s Band Radio Service (low power mobile)

You ever go into Wal-Mart or Best Buy and see those cheap little two-way radios encased in one of the most devious inventions of man-kind (Bubble Packs)? They boast wild range figures (“35 mile Range!”) and are made by many different companies like Motorola, Midland and Cobra. These are called “FRS Radios” (Family Radio Service). FRS radios are restricted to ½ watt, non-removable antennas and are intended for short-range person-to-person communications. While titled as the Family Radio Service they are commonly used by businesses and government organizations. In my neighborhood I hear construction crews, hunters, the local school and the golf course maintainers on FRS channels. Just about everything but families… There are few restrictions on what you can use it for so business and personal communications are allowed.

FRS is actually pretty interesting to listen to in many cases. While a lot of the traffic is inane nonsense, like kids wearing out the noisemaking alert beep button, occasionally there is some interesting stuff to listen to. I live in a fairly isolated area 20 miles from the nearest town. There is construction going on and the crews use several FRS channels to coordinate activities. There is a school in the area that uses FRS radios too. The golf course guys use FRS when performing maintenance or to corral loose duffers. Local landscapers use FRS as well.

Listening to FRS channels at the mall or around amusement parks etc. can also be fun. The stores and shops often use FRS radios for clerks and stockers, customers use them to keep in touch with their family.

A lot of the FRS channels are shared with GMRS, so listening to one set of frequencies you may hear both services.

GMRS is a little different than FRS. Since a license is required and power levels are higher they tend to be used in a more formal matter. FRS also allows repeaters so you may hear traffic from all over the area. GMRS is often used by REACT and other volunteers as well as family businesses and often for just idle chit-chat and radio clubs. Sometimes it sounds a lot like ham radio.

MURS can be very interesting. It is on VHF and allows higher power than FRS but in many other aspects it is very similar. Like FRS there are few restrictions on what you can use it for. Since the radios tend to be a little more expensive MURS channels tend to be more business oriented.

CB these days is mostly a wasteland of unintelligible noise. It is still popular with the highway crowd but between high-power illegal amplifiers, over-driven power echo-mics and other noisemakers it is no longer a viable communications tool. It can be interesting to listen to however!

If you put these frequencies in your scanner you may find some interesting communications. You might also be bored silly but you won’t know until you try it.

Reading the RadioReference Database

One of the best sources for scanner information available is the RadioReference.com database. This is a huge listing of frequencies used thruout the USA and Canada for all types of two-way radio operations.

If you do your own scanner programming then the RRDB is invaluable for information. It is usually more accurate than the agencies themselves have! Even if you only use a database scanner (like a HomePatrol or TRX) then it helps to understand the database so you will have a better idea of what you are listening to. Remember: The data in your scanner came from RadioReference in the first place.

To read the RadioReference database and understand how it works you need to understand how it works. Without understanding how it is laid out it can be daunting, there is a whole lot of information at your fingertips.

To understand it you need to know a couple things. There are two main types of data available, trunked and conventional.

First we will look at a conventional frequency listing. Then we will look at trunking information. (Conventional means that it is not trunked.)

Here is the frequency page for Lee County Florida. It shows several fields:

  • Frequency       (Actual frequency used or the repeater output)
  • Input               (Repeater inputs)
  • License            FCC Callsign, click on this to see what frequencies and other info is available for it.
  • Type               Base, Repeater, Mobile only etc.
  • Tone                Could be PL, DPL or NAC 9for P25) etc.
  • Alpha Tag       A short tag used on some scanners, akin to channel numbers etc.
  • Description     A longer description of the channel and its use.
  • Mode              FM, AM, Digital etc.
  • Tag                  The classification that the channel falls under.

If you hover over the column title it will tell you what the codes mean.

Since so many areas use trunking systems these days one might miss a lot of the info needed to monitor the area. Look at the bottom of the county’s page to see a list of trunking systems active in the county. If you see one that appears to be used there click on it to see the data. The first part you will see it the basic info:

At the top you will see an info box with the system name, location, type and other info. Below that you will see the System ID’s (some scanners will show the System ID to identify it) and other info.

If you scroll down the page next you will see the trunked system Sites. Sites is where you will find the actual frequencies used by the system. Some systems only have 1 or 2 Sites, others (like the one shown) have dozens.

This is a portion of the Site List for the huge Illinois StarCom21 system that has many sites all over the state. There are several columns:

  • RFSS is the Zone number (RF Subsystem), then the Site Number within the Zone. Sometimes Sties are shown in other contexts as X-YYY (1-012 meaning Zone 1, Site 12) or just XYY (112).
  • Next is the Site Name, usually the city or location the site is located in. The county the site is in follows.
  • Last are the frequencies used at that Site. Some freqs will be shown in red, these are known to be “Primary” control channels (mostly for P25 systems). Other freqs will be in blue, these are known to be “Alternate” control channels. The rest are shown in black, these are not know to be used as control channels but are used for voice. Unless you know for sure otherwise, it is usually best to include all channels of the Site in your scanner.

The last part of the Trunked system information is the Talkgroup List. These are the virtual channels used to allow the correct people to communicate within the system.

The columns here are:

  • DEC (Decimal)           The most common way to identify a talkgroup in scanners.
  • HEX (Hexidecimal)     Another way to view Talkgroups, used mostly by the fleet radios.
  • Mode                          Tells you if it is Digital (D), Analog (A), Encrypted (E) or TDMA (T).
  • Alpha Tag                   The short channel name
  • Description                 More inclusive description of the channel and its use
  • Tag                              The classification (Service Type) for that talkgroup.

By understanding the way the data is laid out you can apply this to your programming and understanding of the systems you listen to.

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.

Select a Scanner Based on the Scanner Frequencies Used in Your City

Scanner RadioAny time you are looking at purchasing a new scanner, you need to make sure the scanner is compatible with the scanner frequencies in your area. Otherwise, you will be limited in the number of different channels you are able to monitor. The three radio frequencies used are digital, analog conventional, and analog trunking. Each type of scanner radio, whether it is a portable handheld unit, one installed in your vehicle, or one used in the comfort of your own home, picks up specific frequencies. Just like there are three radio frequencies, there are three kinds of police scanner radios designed to pick up the various radio frequencies.

It is important to first find out what frequencies various agencies utilize in your area for communications. There are several online resources available to help you determine what scanner frequencies are used. One of the easiest to use is on our sister site, www.policescanners.net. Simply click on “Choose a Scanner,” and enter in the range and your zip code, to see what scanner models are recommended for your location. We highly recommend using this resource before you purchase your new police scanner radio. It is free to access this information, and it provides an overview of what the various agencies use for their communications and which type of scanner is best. Since radio systems do sometimes change ahead of what is posted publicly on the website, you may wish to call and double check with your dealer for the latest information about the radio systems in your area.

Now that you have a better understanding of what scanner radio frequencies are used in your home town, it is time to start shopping for a new police scanner. To help you select the best scanner radio, look at the frequencies the scanner receives. Analog conventional scanners only monitor basic analog signals on FM and AM systems. These types of scanners allow you to listen to communications by police, fire, aviation, marine, railroad, amateur radio, racing, and FRS/GMRS transmissions. Keep in mind, if local law enforcement and fire agencies use either analog trunking or digital systems, you will not be able to monitor their communications.

An analog trunking scanner picks up both conventional and trunking analog transmissions, but not digital transmissions. Trunking is a widely used communications system, in both large and small communities, as it allows multiple agencies to share the same trunking system. Transmissions jump from one channel to the next and often each agency has its own talk groups assigned to specific trunking frequencies. Most scanner radios allow you to manually program talk groups and frequencies so you are able to hear communications for the agencies you want to monitor.

A digital scanner is a radio scanner capable of monitoring all three types of scanner frequencies. It can be used to listen to analog, analog trunking, and digital communications. Digital scanners provide the most flexibility, especially if you like traveling or have a job where you are on the road most of the time and want to enjoy listening to your scanner. With more and more agencies moving to digital transmissions, you may want to invest in a digital scanner, now, and be ready when systems are upgraded in your city.

People have various ways for listening to scanner frequencies. They could purchase their own personal radio scanner or use an online police scanner radio. There are several differences between these listening methods. Deciding which one is best for what depends on the frequencies you want to listen to and monitor. Most online scanner applications only monitor a single government agency, such as the Boston Police. If you want to listen and monitor emergency services or fire frequencies, you have to download and install another application. Further, you might be limited to only running one application at a time, so, if you want to listen to multiple channels, you have to open and close each application to switch frequencies.

With a radio scanner, you do not have to worry about these issues. Instead, you can configure your scanner to monitor and scan the frequencies you want to listen to, or set it to one specific channel. There is no software to download, install, or update. An online police scanner requires maintaining an active Internet connection in order to listen to channels. If your Internet connection goes down, you cannot listen to an online scanner. When you use a radio police scanner, you do not require an active Internet connection. The device operates using either AC power, or batteries, to monitor scanner frequencies.

Another major difference between a radio scanner and an online police scanner is the number of channels you can monitor. With an actual police scanner, you are able to monitor your local area in far greater depth, compared to an online scanner. You have access to more channels, like public works, railroads, college campus police, taxis, and several other agencies not available with online scanner applications. However, keep in mind, actual radio scanners do have limitations on the distance they are capable of picking up frequencies, depending on the model of scanner you use. Without an outdoor antenna, physical scanners ranges are between 10 and 30 miles. If you do not want to install an antenna and want to hear frequencies farther away, then an online application would be more appropriate.

Scanner monitoring laws and regulations vary, from state to state. Some states do allow people to use portable radio scanners in their vehicles and other locations whenever they are not at home or work. It is your responsibility to review the laws in your area in regards to where you are allowed to use actual scanner radios and online scanner applications. Taking the time to review these regulations prevents you from using the wrong type of police scanner or scanner application. It hardly needs mentioning that regardless of whether you use a police scanner radio or an online application, it is against the law to use a scanner or monitoring device during the commission of a crime.
