One of the questions we often get here at Scanner Master is how I can listen to whatever is around me. While the ZIP Code scanners are the way to go for this some people think that by using the Close Call feature one can listen to all the activity in the area. While this would be a great idea it really doesn’t work that way.
Close Call and ZIP Code scanning have some similarities but are really two different animals. Close Call (and the similar Whistler/GRE/RS feature called Spectrum Sweeper or Signal Search) is a near-field receiving option that scours the bands for strong signals and locks in on them. You can then see the frequency displayed. This is great but it has limitations.
The range Close Call works at depends on the strength of the signal, it has to be very strong to trigger. Portable radios usually have to be within a few hundred feet, mobile radios within a block and base stations or repeaters within a few blocks. Sometimes you can get stations further away but that depends on so many factors like antenna, frequency, elevation etc. that anything beyond those distances is considered luck.
Close Call is a great way to find new frequencies, especially at less documented sites like shopping malls and events. It is a great tool to find all those walkie-talkies used at locales and events but cannot be used as a replacement for proper scanner programming. One feature it lacks is the ability to look up a channel in the database or programming of the radio.
ZIP Code programming is recommended for those traveling thru an area if you don’t know what frequencies are being used there. Chances are the main channels are already documented on Radio Reference and thus should be in the internal database on your ZIP Code enabled radio. Uniden ZIP Code scanners also support the use of a GPS to automatically update the location as you move.
Be sure to use the right location service for your needs. Need to find new local (VERY local) channels? Use Close Call. Need to listen to specific services or systems in a particular area? Use the ZIP Code feature.
One of the questions we get here at Scanner Master is how often one should update the programming on their scanner. The answer to that depends on a few things, including what kind of scanner you have, the resources available to you (computer, software etc.) and what is happening in your area.
The type of scanner you have is the first question we always ask. ZIP Code type scanners, such as the HomePatrol, x36/SDS type or the Whistler TRX and WS types are pretty easy to update with the free Sentinel or EZ-Scan software. With a Windows computer these can be updated as often as you like at no charge just by running the software and sending the updated data to the radio. Remember that updating the database does not update the Favorites Lists that you may have so if you are using Favorites Lists check them for any changes.
If you do not have a Windows computer or do not want to do this you can always let Scanner Master do the work for you. We sell fully programmed and ready to go SD Cards for your Uniden or Whistler ZIP Code enabled scanner for just $59.95.
On other modern scanners, such as the various Uniden, Whistler, GRE and Radio Shack digital radios (and some analog ones) they can be programmed by computer with the appropriate software and cables. If you have access to programming software then you can update these easily whenever needed. Scanner Master sells programming software for almost all the current scanners and most older ones. – Read more
The third question relates to whether you actually need to change it or not. There are some places using the same channels they have for 20 years or more, the Chicago Police Department for example is using the same radio channels they were in the 1970’s for the most part. Other areas have changed frequencies or systems several times over the last couple decades.
For ZIP Code scanners we normally suggest that you update the database when you buy the radio and perhaps once or twice a year after that. If you go on a trip and are bringing your ZIP Code scanner with you update the database before you leave. You might have to update the scanner if you know that your targets have changed systems or perhaps they disappeared and you no longer hear them on the channels that once used.
For non-ZIP Code type scanners it is a little more difficult. Since these are pretty much custom programmed for your area you might have to tweak them from time to time to add a new channel or agency. If your targets move to a new system then you would need to reprogram or replace the scanner, depending on whether the scanner is capable of monitoring the new system.
We also suggest that you monitor the forums for your area at Radioreference.com. When things change they are usually discussed there, often in great detail.
As always, Scanner Master will be happy to help you reprogram your scanner, either with a replacement SD Card or by using our main-in programming service.
Here are a Baker’s Dozen of hints and tips to make life with your new SDS100 scanner happier. If your question is not answered let us know and maybe we can add it to Part 2!
1) What is the deal with the battery?
Uniden designed the radio with a new Lithium Polymer battery pack, getting away from using common AA cells. While a lot of people preferred the AA cells since they can be easily obtained and swapped out, they just could not provide enough current to run the radio for a decent amount of time. The Lithium Polymer pack that comes with the radio was supposed to be sufficient but Uniden was not happy with the results so they designed a larger pack to be used. Unfortunately the radio was already on the assembly line by the time it was discovered that the battery life was not up to snuff.
Uniden decided to allow the radio to be sold and distributed as it was but included a notice in the box to advise purchasers to sign up for a FREE larger battery pack once they are available, likely in August 2018. Sign up at Uniden’s website and they will send you the new larger battery as well as a replacement battery door at no cost.
Once these batteries are available there should also be available for sale extra batteries. Eventually some sort of external charging device will also be available so you can charge one battery while using another.
2) Can I charge the battery and run the radio at the same time?
Actually, on the SDS100 you can! While other Uniden scanners do not support this, as long as your charger has sufficient current capability you can charge the battery with the radio on as long as you have that option turned on in the Settings>Battery Options>Set Charge While On menu.
Why would you not want this option turned on? The only reason I see is that the red or green charge light will be on all the time when the radio is plugged in. It might take a while longer to charge the battery when the radio is on but it should not be a big issue.
3) What else can I use to charge the battery?
The SDS100 comes with a USB charger. Alternately any USB charger will power and/or charge the SDS100 battery. If you have a smartphone or other USB device charger you can use it if you don’t want to use the charger that came with the radio.
In the car you can use any USB port to power/charge the radio. Most cars these days will have a USB port to charge your phones and other devices, these work well with USB powered scanners like the SDS100.
4) What is the deal with the raised ridge by the antenna connector?
That ridge is part of the water proofing of the radio. When used with the supplied rubber duck antenna this helps provide a seal to block water from getting into the radio. The supplied SDS10 antenna has a rubber gasket that fits this ridge.
This does however block use of many third-party antennas and adapters. The SDS100 comes with an SMA-BNC adapter so you can use your BNC antennas but with this adapter you will not have the water resistance provided with the supplied antenna.
5) What is that little hole on the back of the radio? Am I missing a screw?
That hole below the belt clip knob is there to provide a case breather to prevent pressure issues. The radio is still water resistant due to other parts inside the case. On some radios there have been issues with elevation changes causing the case to pressurize and damaging components. This pressure relief helps to prevent these issues.
6) It is hard to see the color screen in sunlight, what can I do?
The SDS100 color screen is a thing of beauty but can be difficult to read in direct sun. If you go into display settings you can select white on black or black on white instead.
7) What are the “Detail” and “Simple” screen modes?
The SDS100 has a fully customizable display. You can set it up to display just the basic information (Simple) or all kinds of special information (Detail) when receiving. Almost every item can be positioned where YOU want to put it. You can even select the colors each item is displayed in.
Simple Mode shows just basic information in an uncluttered way. Detail Mode allows you to show many different details about what you are listening to, such as trunking ID’s, PL tones etc. so you can analyze systems you are listening to. You can switch between these at will and change the way they look on the radio via the keypad or Sentinel.
8) What are the software options?
The SDS100 uses the free Sentinel software to do the database and firmware updates. This is the same version as used on the BCD436HP and BCD536HP scanners and you can share files back and forth among all 3 radios. There is a separate version of Sentinel used for the HomePatrol models. The HomePatrol modes Sentinel has a brown icon, the 436/536/SDS version uses a green icon. Sentinel can also be used for programming Favorites lists as well.
ARC536 by Butel can be used to also program Favorites Lists, it provides the familiar Butel interface so if you have used other ARC products you will feel right at home. The Pro version also supports Virtual Control as well as other features.
9) Will there be a base/mobile version of the SDS100?
Yes! The SDS200 is identical in operation and programming to the SDS200, but in a mobile package with a larger display.
10) How does the GPS unit connect to the SDS100?
The Uniden BC-GPSK GPS receiver works on many different Uniden scanners and comes with several cables to adapt it to these scanners. With the SDS100 (as well as the BCD325P2) however you need a different cable. This special adapter cable, available at scannermaster.com, replaces everything but the GPS disk and attached cable. Plug the round plug from the GPS into this cable, the USB plug into a USB power source and the small plug into the Charge/USB jack on the radio. The radio will be powered/charged from the GPS cable as will the GPS itself.
11) Sharing Favorites Lists with other scanners
The SDS100 can share the same Favorites Lists as the BCD436HP and BCG536HP, and since they all use the same version of Sentinel, it is really easy to share. You can create different Profiles for each scanner if you want or just program them all the same.
To share files from other radios you would need third party software and import/export those files with that software.
12) If I have many Talkgroups or Sites in my trunked system will it slow down the scanner?
If you have many TALKGROUPS then no, it will not slow the scanner down. The SDS100 (and other Uniden scanners) does not actually scan talkgroups, it scans SITES and if it sees an active Talkgroup it looks to see if it is in an active Favorites list and Department. If it is it displays the name and listens to the talkgroup. If not it ignores it and moves on. All this is done in fractions of a millisecond.
If you have that trunked system’s Favorites List set to Trunked Search the scanner will look for the talkgroup and see if it is listed. If it is in the radio it will show the name etc. and hear the traffic. If it is not already programmed into the radio it will display it as “Unknown” with the Talkgroup number. If you can identify the user you can add it to your Favorites List.
What can slow down your scanner is if you have a lot of SITES programmed into the radio that you have no chance of hearing. If your area uses a large regional or statewide system then either turn off or delete the sites you would not be able to hear. (The radio’s manual describes how to do this…). The fewer sites the radio has to go thru the faster it will get to them.
13) Do I need ProVoice, DMR or NXDN?
Well, maybe, maybe not… Check the RadioReference database and see if anything in that area use these modes. If they use them in the areas you want to listen to then you might want to get the upgrades. ProVoice is used mostly by public safety agencies in specific areas including Oklahoma City, San Antonio, Denver and Albuquerque.
DMR and NXDN are mostly used by business operations and campus installations but are occasionally used by smaller police and fire departments as it is less expensive than P25 digital systems.
14) Where can I go for more information?
https://wiki.radioreference.com/index.php/SDS100_and_SDS200_FAQ_Page has a ton of info on the SDS100 and SDS200
If you haven’t heard already, the new Uniden SDS-100 handheld digital scanner has taken the prize as the most desired scanner available. Introduced in the spring of 2018 and finally available in June, we sold every one we had and were promised and just now are able to keep them in stock for regular purchases.
What makes the SDS-100 so special? Why does it work so well? Why is it worth all the extra money it costs? Glad you asked!
The biggest advantage to the SDS-100 has over other scanners is it’s ability to monitor Linear Simulcast Modulation (LSM, also known as P25 Simulcast) systems. Traditional scanners do not work very well often with LSM systems but the SDS-100 handles them much better, almost as well as a regular system radio like the police use. Other scanners tend to break up, miss words or phrases or just not hear it al all.
Why, you might ask, does this happen? Simply put, a simulcast system transmits the same traffic on the same frequencies at the same time from 2 or more locations. A simulcast system would transmit from multiple sites to provide better coverage within its intended operational area. These signals then tend to arrive at your scanner with slightly different time delays. Even though these time differences are almost indescribably small, the fact that they are digital1’s and 0’s makes them interfere with each other. The 1’s from one tower tend to block the 0’s from another tower. This causes interference and sometimes the interference is so bad as to block the entire conversation.
The SDS-100 uses a totally different internal architecture than other scanners, basically using a Software Defined Radio (SDR) with True-IQ processing to more properly decode LSM transmissions. This means that the SDS-100 will receive these simulcast systems with little to no distortion or interference.
There are other advantages to the SDS-100 SDR-based architecture. It allows other features and capabilities to be added down the road. While Uniden has not announced any of these features yet the possibilities are endless.
The SDS-100 works much like the BCD436/536 series scanners, the interface is very similar and they use an updated version of the Sentinel software so you can share your Favorites Lists between them.
The other big feature with the SDS-100 is the color display. This display can be used in either a “Simple” or “Detail” mode. The Detail mode is entirely customizable. You can place any of dozens of different fields almost anywhere on the screen and assign any color to just about any item. You can switch back to Simple mode and just have the basics, still in color or even switch to a simpler black and white scheme that works better in bright sunlight.
The SDS-100 is an amazing radio. If you have simulcast systems in your area then it works much better than other scanners. While it is more expensive than other scanners it is well worth it!

Learn how to do the following:
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.
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:
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.
Here are a few of the common questions we get here at Scanner Master’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.

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:
Other common ports on scanners include:
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.
