How often should you update your scanner programming?

Posted on by

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.

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

Posted on by

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.

Force Write full Database (HP1, HP2 BCD436 and BCD536)

Posted on by

When updating a HP series (HomePatrol 1 and 2, BCD436HP and BCD536HP) scanner one of the update is the database that the ZIP Code feature relies on. If the database has old or incorrect data then it can affect whether you will be able to hear your target. If you update the database on a regular basis you can help ensure that you will hear what you want.

When you update the database within Sentinel (the free software provided by Uniden to support these scanners) it doesn’t actually update the database on the scanner itself. You have to “Force-Write” the database to the scanner. This is easy; after you “Update Master HPDB” in the Update menu just click the “Force-Write Full Database” button on the Write to Scanner (or Write to HomePatrol) item in the Scanner (or HomePatrol) menu.

This ensures that the Master HomePatrol database on your scanner is up to date.

GPS Based Scanning Tips

Posted on by

Several Uniden scanners support GPS based scanning. There are two main ways this works; Database based and Programming Based.

Scanners that support ZIP Code based programming (The HomePatrol and x36 types) can support GPS in both ways. Scanners that do not have the ZIP Code feature only support Programming based GPS.

ZIP Code based GPS scanning allows the radio to reload itself with the local frequencies based on locations provided by the attached GPS receiver. Instead of pulling over to change the ZIP code every once in awhile the GPS receiver sends the location to the scanner and it will update the location on a regular basis and reload the channels for that area.

Since these use the RadioReference database to provide the information, the GPS centers and ranges are set in the database and included when you update the scanner’s database in Sentinel.

Programming based GPS scanning requires that the Systems, Sites and Groups (or Favorites Lists) be programmed with GPS coordinates and ranges. The GPS sends the location to the radio and when the radio determines that you are within the circle drawn based on the location and range it turns on that item. When you leave the circle it turns it off.

If you use your scanner over a wide area a GPS can allow you to automatically turn on and off systems, sites, groups and/or Favorites Lists automatically and without having to punch in a ZIP Code all the time. If you only use the scanner at home or around a small area a GPS wouldn’t help you but if you travel a lot (RV folk, truckers etc.) it can be invaluable.

Most people use the Uniden GPS receiver with their scanners. It works on all Bearcat GPS-aware scanners without needing to configure it. If you want to use another GPS it has to support the older Serial format and the baud rate settings must be set to match that of the scanner. Most GPS receivers these days (Garmin, TomTom etc.) do not support Serial mode so you will likely be better off with the Uniden GPS.

Sentinel, Sentinel: What’s the difference?

Posted on by

Owners of Uniden ZIP Code scanners can use the free Sentinel software to do database and firmware updates as well as create and edit Favorites Lists. While they look and feel very much the same, the versions of Sentinel for the HomePatrols is different than that for the BCD436HP and BCD536HP.

The HomePatrol Sentinel works for both the original HomePatrol 1 and the newer HomePatrol 2. When installed on your Windows computer it will have a brown shield icon on the desktop.

The BCDx36HP Sentinel works for both the BCD436HP handheld and the BCD536HP desktop/mobile scanners and has a green shield icon on the desktop.

You can easily share Favorites Lists between HP-1’s and HP-2’s as well as between 436’s and 536’s. In order to share Favorites Lists between HomePatrol’s and “x36’s” you need to export from one and import it to the other.

If you have both types of radios you will need to install both versions of Sentinel. Even though they look and feel the same they cannot handle the other radio types. There is no additional learning curve but there are a few terminology differences. For example, in the HomePatrol Sentinel the menu used to read or write to the radio is called “HomePatrol” while the x36 version it is “Scanner”.

When the data isn’t right: How to get your database scanner working.

Posted on by

So you went out and bought one of these fancy new database scanner like the HomePatrol, BCD436/536 or a Whistler TRX and set it up. The problem though is that you are not hearing your local channel that you expected. There are a couple things to try. The first is to double check that you have the location and Service Types set properly. If these are correct, did you accidentally lockout (“Avoid”) the Channel, Department or System?

If you have ruled out these issues take a look at the RadioReference Database at RadioReference.com. This is where the frequency information comes from. If the channel is listed there but not included in your radio then you need to update the database on your radio. Make sure you have installed Sentinel (Uniden) or EZ-Scan (Whistler) and run the update procedure for these scanners. After updating the database make sure you copy (“Write”) it to your radio and try it again.

If you find that the channel is not listed in the RadioReference database then you will have to do some detective work. If you know what the frequency or talkgroup is then be sure to submit it to RadioReference so it can be added or corrected in the database. All you need is a RadioReference user name and password, either a free or paid membership will work. In the meantime it can be added to a Favorites List or Scanlist via the software.

If you do not know what the channel’s frequency or talkgroup is then you will need to do a little more work. If you know they use a trunking system then create a Favorites List and set it to Trunked Search (if on a Uniden). If you have a Whistler then create a ScanList with that system and add a Wildcard to it. This allows you to listen to all activity on the system and when you hear the traffic you want make sure you note the talkgroup number for future reference. You can submit that talkgroup number to RadioReference to update the database and also add it directly to the Favorites List or ScanList with the appropriate name.

On conventional (non-trunked) systems you can do a couple things. First off, check the FCC license for the agency you want to listen to. Most of the time you can do this from the RadioReference database page, just click on the call sign. Since the RadioReference Database only contains information that is verified a new channel might be listed on the license but not included in the main database since no one has reported it as verified yet.

If the channel you seek is not listed there, check licenses for nearby communities, the local County or a regional dispatch center. The actual license might be held by another agency that does dispatch for your town.

Still cannot find it? Now it is time to get serious! Your scanner has a “Search” function. Learn how to set up a Limit Search. Check the most common scanner bands used in your area and set up a search for that band. Lockout the channels as you hear them if they are not your local agency, checking the RadioReference Database as you find them.

Regardless of how you find them be sure to share the knowledge. Submit your finds to the RadioReference Database system so that others in your area can listen in and so that future versions of the database include it. Remember that the database is updated weekly, usually Sunday or Monday. Submissions might take a little while to get processed however so wait to the following week after you receive the notification that your submission has been worked.

ZIP Code based scanning: How does it work?

Posted on by

One question we get all the time here at ScannerMaster Intergalactic World Headquarters is “when I put my ZIP Code in my (HomePatrol, 436 or 536) scanner how do I hear something in the next ZIP Code over?” The answer is that you already are… Let me explain.

On the Uniden ZIP Code type scanners (Home Patrol, BCD436HP and BCD536HP) when using the ZIP Code method of scanning (versus using Favorites Lists) you enter your local ZIP Code into the “Location” menu. You then can set the range (in miles). The ZIP Code acts as a center point on a map. The range is how big a circle that is drawn around the center point of the ZIP Code. More miles equals a bigger circle; a bigger circle equals more stuff programmed into your radio.

So if you live in Mayberry and your ZIP Code is 27031 you would enter it in the scanner. You then set a range; let’s say 15 miles. Draw a circle 15 miles in any direction from the center point of the ZIP Code and that is your primary coverage area. When the radio loads up it will load all the channels that are in that area, based on the service codes you enabled. Simple, right? Well, not so much.

The way the HomePatrol Database is constructed is that each entry itself also has a geographic location assigned to it with a range. So the various entries in the database all have their own circles. If any of these circles touches or crosses your circle then they will be entered into your scanner. For this reason you may hear things that are actually outside your circle.

Let’s say that Mt. Pilot is 20 miles from Mayberry, where you are. If you set your range to 10 miles you may not expect to hear Mt. Pilot. In the database however the Mt. Pilot stations are set to a range of 15 miles. So the Mt. Pilot circle goes out 15 miles and crosses the 10-mile circle you set in Mayberry. Therefore you will have the Mt. Pilot channels in your scanner. Clear as mud, right? Well wait, it gets even weirder!

So, you see Mt. Pilot’s frequencies on your radio but you never hear them. Why is that? Your range is set to include them and they show up but the radio doesn’t stop on them. There are a couple possible answers:

The first reason may be that they are too far away. Just because they are within the range settings of the radio doesn’t mean your scanner will actually be able to hear them. Perhaps sometimes you can hear them and other times not. Radio signals are predictably unpredictable.

Systems are designed to reliably cover specific areas. When you are within those areas your scanner should be able to hear them all the time. When you are outside the main coverage area it all depends on things like elevation (yours and the transmitters), terrain, obstructions, distance and sometimes even the weather. If there is a mountain between you and them you may not hear them. If you cannot hear them you might want to try a taller antenna, but that is a post for a different day. A good rule of thumb is that if the agency’s radios work where you are your scanner should as well.

Another reason might include the database being wrong. The HomePatrol Database is derived from the database at RadioReference.com. This is maintained by scanner enthusiasts all around the world. Some areas are better covered than others. If there are a lot of dedicated scanner users in the area the database is liable to be more accurate.

Still another reason might be that your scanner is not capable of hearing the type of signals used.

Whistler ZIP Code scanners work differently. You select a location and the radio offers a set of systems and channels to enter into a ScanList. The same thing applies for distance however; you may not hear something that is closer than others due to obstructions, low antennas or power.

If this is all too confusing for you then have ScannerMaster perform its “Setup and Optimize” service on your scanner. We will set up Favorites Lists for your county or counties so you will only have the items programmed into your scanner that you really want!

Favorite Scanner: BCD436HP

Posted on by

The BCD436HP (commonly referred to as the “436“) is Uniden’s premier handheld scanner. It takes the Location Based Scanning system from the HomePatrol and merges it with the huge feature set of the BCD325P2. You get the best of both worlds; easy ZIP code based scanning and the flexibility and functionality of a full featured professional scanner.

Remember the commercials for the candy where some guy got his chocolate into another guy’s peanut butter? Well, imagine mixing a HomePatrol 2 with a BCD325P2, instead of a tasty peanut butter cup the end result is a BCD436HP.

The HomePatrol’s ease of use required the removal of several key features that were present on other scanners, this included things like CloseCall, Limit Search, Fire Toneout and keyboard programming. While most HomePatrol purchasers do not need these features there are others that want them. The “436” restores all of these features and more and keeps the Location Based scanning of the HomePatrol. With Phase 2 capability, the 436 works almost everywhere in the USA and Canada, just by putting in a location.

The 436 also now allows one to listen to ProVoice. These are used in a few areas of the country and until recently could not be heard by any scanner. With the extra-cost ProVoice option you can now hear unencrypted ProVoice digital systems such as used in San Antonio or Oklahoma City among other areas.

The 436 also has the ability to record conversations heard on the scanner to it’s built-in SD Card, allows analysis of trunked radio systems and more. You can program it on the fly like you would older scanners, use a computer to program it or just let the radio use it’s internal database.

The 436 comes with the free Sentinel software to update the firmware and database (Windows only, sorry Mac dudes!) as well as rechargeable batteries, a USB cable and antenna. You charge the batteries with a USB charger, available at extra cost or just use the one from your cellphone or other USB device. It covers most scanner frequencies from 25 to 1300 MHz. and works on AM, FM, FMW, P25 Digital Phases 1 and 2 as well as ProVoice digital (requires extra cost key for ProVoice). Optional ARC software is also available for control and advanced programming.

The BCD436HP is available from ScannerMaster at BCD436HP or just call us at 800-SCANNER.

Uniden Scanners

Zip Code Based Scanning: How does it work?

Posted on by

You say you are interested in a “ZIP Code” scanner like a HomePatrol, BCD436HP or BCD536HP? You like the idea of having the scanner do all the programming by itself but don’t understand how it works? Here are the answers you are looking for! The HomePatrol and x36 scanners are wonderful technology and take a lot of the work out of scanning. By understanding how they work you can better understand how to use the radio and address any issues that might pop up.

First of all there are a couple misconceptions about these scanners. One common one is that they will only hear things in the chosen ZIP Code. This is incorrect. “ZIP Code” scanners use the location you enter into the radio (either by ZIP Code, city and state or by GPS coordinates) as a CENTER POINT. You then enter in a “Range” in miles, this creates a circle around that location. The larger the Range setting makes a larger circle and more stuff that will be programmed into your radio. The Range setting only affects what is programmed into the scanner, not the actual distance it will receive from.

When you set a location and range the radio will automatically program in all the services you selected within the circle and allow you to listen to it. If a Service Type is unavailable to be selected (greyed out) that means the database has no channels with that Service Type within the circle.

So what happens when you need to listen to something 20 miles away but really don’t want to listen to another area closer in? This is where the “Avoid” system comes in handy. Learn how to use the Avoid key on your scanner and use it to lockout Channels, Departments or Systems from your radio to help tailor your listening. “Avoid” works much like the Lockout function in older scanners. “Temporary Avoid? Means that the item will be locked out until the radio is shut off, the item will return the next time you turn on the radio. “Permanent Avoid” will cause it to stay locked out until you go in and “unavoid” it.

There is another way to easily tailor your HomePatrol or “x36” scanner to your preferences. This is by using Favorites Lists. Favorites Lists are basically your own frequency sets for your area. Instead of using the Nationwide Database and going strictly by location, a Favorites List will allow you to import Systems from the Nationwide Database or create your own from scratch. This is usually done with the Sentinel program that comes with your scanner. You can also work on Favorites Lists with ARC-Patrol (for HomePatrol’s) or ARC-536 (for the BCD436HP and BCD536HP).

To create a Favorites List you would import items from the Nationwide Database into it. You can then edit the information but adding or deleting your own information. You can also create a List from scratch and built it from the ground up.

If you selected ScannerMaster’s Optimize option for your HomePatrol or x36 scanner we would have created a Favorites List for you for your area. You can edit this if you want with Sentinel. You can also edit this from the scanner itself but this can be time consuming and kind of daunting. It is a bit easier on the 436 and 536 than the HomePatrol but we recommend that you do this in Sentinel, trust me it is a lot easier!

So where does the database itself come from? It comes from you and me! A website called RadioReference (www.radioreference.com) hosts a database where scanner users from all over the world share information. Each state and province has one or more Database Manager’s that filter submissions from users and update the main database. Once a week Uniden retrieves a copy of this database and makes it available to scanner users via Sentinel.

When bad things happen to good scanners: SD Card Corruption

Posted on by

All of the various “Zip Code” type scanners such as the Uniden HomePatrol, BCD436HP or BCD536HP, Whistler WS 1080/1088/1095/1098 or the GRE and RadioShack versions use a Micro-SD Card to store the database and recordings. This SD Card is much like a disk drive without moving parts, it can be written to and read by a computer or a device; in this case your scanner.

Occasionally these cards can get corrupted which causes them to stop functioning. The scanner will display an error message and will not operate until you repair or replace the SD Card. Thankfully this is not usually a serious issue and rarely results in anything other than some annoyance. The worst that can happen is that you lose your Favorites Lists and any recordings you may have on the card.

First let’s talk about WHY this happens. Most of the time it is due to the power being removed from the radio abruptly. These scanners are basically small computers and, like all computers, they need to be shut down properly. By doing so the radio has a chance to finish writing information to the SD Card. If the power is removed before this is done then an incomplete or corrupted file may be left. When you turn on the radio the next time it doesn’t know what to do with the file and displays the error message. While this does not occur every time the radio is improperly shut down, it only has to happen once to ruin your day.

Now there is always the possibility that the card or even the radio itself is defective but that is very rare.

What can you do to prevent this from happening to you? The best thing you can do is to make sure you turn the radio off before removing power to it. If you have it mounted in a vehicle be sure to turn off the radio by use if the volume/power knob before starting the car or turning off the ignition. If the radio loses power while still turned on then the card can get corrupted. Same goes for portable radios. do not pull the batteries unless the radio is turned off.

OK, my card got corrupted, is my scanner dead? Usually no. These cards can usually be reformatted and the database rebuilt. Even if the card is shot it can be replaced and the new card set up for your radio. You can get replacement (or spare) Micro SD Cards almost anywhere.

What can you do if this occurs to you? First make sure the card is really corrupt, some times they are just loose. Remove the card and reseat it, making sure that it clicks into place. When you turn on the radio, if it works then you are back in business. If you still get the error then you will likely have to reformat the card.

Of course the easiest way to get past this is to let us fix it for you! Just download, print and fill out the form at https://www.scannermaster.com/v/vspfiles/files/pdf/homepatrol-servies-order-form.pdf. Send it to us with the radio and we will do the rest!

To reformat the card it is best to use an application specifically for this. You can use a free program available from https://www.sdcard.org/downloads/formatter_4/. Download the one for your version of Windows and install it. You can use an SD Card reader if you want or leave the card in the radio and connected to the computer in Mass Storage Mode. If you reformat it using Windows directly it may not be done in the proper format. Sorry Mac guys; you need Windows for this!

Once reformatted you need to reinstall the database. On Uniden scanners this is done as follows:

1: In Sentinel under the Home Patrol menu select Clear User Data, click on the Display All Drives box.

2: Be sure to select the correct drive letter then click OK. (You do not want to erase your C Drive!)

3: Run Sentinel on the computer and select the Update Master HPDB option in the Update Menu.

4: In Sentinel under the HomePatrol menu select Write to HomePatrol .You may need to select that drive again, but it will not show the serial number of the radio this time.

5: Eject the card and put it back into your scanner (if not already there). When you turn on the scanner you should be all set. You many need to reset your location, Service Types etc.

Of course this requires that you have Sentinel running in a Windows computer. If you don’t have Sentinel installed (it comes on the SD Card…) you can download it from Uniden’s website.

Whistler, GRE and RS scanners use slightly different procedures, check the manual for your radio for these.
