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.

WiFi on BCD536HP. How does it work?  What you can and can’t do with it.

The Uniden Bearcat BCD536HP is the only scanner that has the capability of being directly controlled by WiFi. By using the included WiFi dongle one can connect a smart phone or tablet to the scanner and listen to and control the scanner with the device. There are some other uses for the WiFi dongle as well.

Uniden has provided free “Siren” software (available for free via the Apple iTunes store or Google Play Store) to allow you to use your smart device as a scanner controller. You can even use this as a remote head for the scanner if mounted in a vehicle or to listen to your scanner from the patio or another room of the house for a scanner installed in the home. Some third party software allows you to use the WiFi feature to connect the canner to the computer without the need to plug in a cable.

There are a few things that the WiFi dongle will not work for, this includes database and firmware updates and other programming.

The Wifi dongle is designed specifically to work with your home or office WiFi network. While we have read of people using it for remote access this requires such networking tools as VPN, if you know how that works you probably can figure it out. Sorry, we cannot help with notworking issues like this!

To use the WiFi feature you need to understand the two modes involved; Infrastructure and Access Point.

Infrastructure Mode allows your scanner to connect to your home or office WiFi. This then allows you to connect to the scanner via third-party software like ProScan or RadioFeed or to the Siren application.

To get to Infrastructure Mode use the following steps:

Press Menu then select WiFi Setup>Select WiFI Mode>Infrastructure Mode

The radio will look for local access points and list them. When it displays the list select your router’s SSID name.

Then enter your password for the WiFi access point. This is the same password you would use for setting up any other WiFi device on your network. To enter the password you scroll thru the letters and use the 4 and 6 buttons to move the curser.

Access Point Mode allows you to connect you scanner to a smart phone or tablet (iOS or Android) using the free Siren software. You would use this when you are not in range of your WiFi system, such as when the radio is mounted in a vehicle. This allows you to use a phone or tablet as sort of a remote control head for the scanner.

In Access Point Mode the 536 acts as an Access Point and provides an SSID which you can change or leave at the default. You then connect your phone or tablet to that WiFi SSID and enter in the IP address in the Settings of the device. The IP address can be found in the WiFi settings on the scanner.

Siren is the free app available at the Apple iTunes Store for iPhones, iPads and iPod Touch’s. It is also available for Android devices at the Google Play Store.

Siren is a neat way to use your 536 scanner but there are limits to it. It will only work with the 536, and it has limited abilities for control. It can set the range, select Quick Keys, set the squelch and start and reply the recording features but that is pretty much all she wrote. There is also a 2-3 second delay in hearing the audio compared to the radio itself.

The WiFi feature on the 546 is unique and useful as long as you know its limits.

Scanner 101 – Tips on picking and installing a Roof Top Antenna

Have you been putting off installing a roof top antenna for your scanner? A roof top antenna is the best way to increase your scanner’s range.

What antenna should you pick?
When selecting you should keep the following in mind:
What type of communication systems are you monitor? VHF, UHF and 700/800/900MHz so on… If the area is using the same type of communication system you may want to consider a single band antenna. If there is a mix I would recommend “wide band” antenna.

Mounting your antenna
When selecting antenna you want to keep in mind; how and where you’re going to mount it. So many options available from non-penetrating, tripod, and wall mount. Keep way from power lines and telephone/cable wires. The higher the better, be sure you clearing anything that would block signals such as chimes.

Coax Cable
Your antenna performance depends on great coax cable! We carry LMR-400 Coax cable which is a high-end low signal loss coax. When planning out your coax routes, be sure you have a little extra, but not too much. Shorter runs are always best. Keep this in mind: the old carpenter rule of thumb, measure twice, cut once!

Will you have multiple listening locations?
Depending on how many listening locations you have in mind, you will need a 4 Port or 8 Port Multicoupler. This should be placed somewhere in a central location in your home or office. I would recommend running LMR-400 Coax cable (no more than 100 feet) from the antenna to the Multicoupler. From the Multicoupler to the scanners I would recommend LMR-400 or RG-6 Coax (no more than 50 feet). Both of the multicouplers have a built in pre-amp to cut down on signal loss going to the monitoring locations.

Installing the antenna
If your pretty handy this can be something you can do on your own, with help from a friend. Just following instructions provided with the antenna. If heights are not you thing I would recommend hiring help.

Scanner Master is your one stop shop for your entire base scanner antenna needs – from antennas to coax to mounting gear! Spring is here; don’t keep putting it off! Make 2012 the year to upgrade your scanner’s reception.
