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

Posted on by

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.

DMR, ProVoice and Ultimate Updates for Uniden Scanners.

Posted on by

ScannerMaster offers a service to install the various paid updates for Uniden HomePatrol, x36 and P2 series scanners. These updates include the HomePatrol Ultimate Update (for HomePatrol 1 and 2 scanners) as well as the ProVoice and DMR/TRBO updates for the BCD436HP, BCD536HP, BCD996P2 and BCD325P2 scanners.

If you buy one of these scanners from ScannerMaster we offer a service to install these options for you before we ship the scanner. You can also send the scanner to us to perform the update, we then send the radio back to you.

Sometimes however it is not practical to send the radio to us. For US and Canadian customers it is pretty simple to buy the update directly from Uniden and install it yourself. For customers in other countries however it is a different story. Uniden can only accept credit cards from US and Canadian addresses. If you live in other countries then Uniden cannot accept your credit card for payment for these updates. They will refer you to a third party like ScannerMaster to obtain your updates.

ScannerMaster can accept credit cards from most countries. As long as the card works on our payment system we can provide you with the secret code to unlock the update for your radio. There are a couple things you will need to do to make this all work out:

First you need to update the FIRMWARE for your scanner. This is so important that if you don’t do it the paid updates just will not work! On the HomePatrol and x36 scanners it is done thru the Sentinel software, on the 325 and 996P2 radios it is done thru a separate (free) program available from Uniden’s website.

Once you have done the Firmware Updates then you need to obtain the “ESN” (Electronic Serial Number” from your scanner along with the “SUM” code. Here are the procedures for this:

HomePatrol-1 and HomePatrol-2:

  • Press Menu
  • Press Advanced Menu
  • Press the down arrow to get to the second page of items
  • Press the Version Information Button.

The ESN is listed and starts with 36 for the HP-1 and 37 for the HP-2. The SUM Code is the last 3 digits past the second dash. The ESN will look something like 36327-0040012345-123, the SUM code is the “123” part.

BCD436HP, BCD536HP, BCD325Ps and BCD996P2:

  • Press Menu
  • Select Settings.
  • (If you do NOT see “Upgrade” as an item in the list go back and update the firmware and start over!)
  • Select See Scanner Information
  • Select Firmware Version
  • The ESN will be listed as “SN37……”
  • The SUM Code will be a 3-digit letter/number combination.
  • We need both the ESN and the SUM Code. Don’t worry about the M-VER code.

We need the complete ESN and the SUM Code as well as the model of radio you have. With this info we can obtain the one-time code that unlocks the feature you want and send that code to you. You then go to the Upgrade menu on your scanner and enter it using the rotary knob to select the numbers. Once the code is properly added the radio will think it over for a minute or so and then announce that it was successful.

Once properly updated the code will stay working on the radio and will not need to be reinstalled. The code will only work for the radio it was obtained and if you dispose of the radio there is no way to transfer the code or feature to another radio.

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.

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.

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.

 

Why Do I Need a Uniden Scanner with Internet Scanner Apps?

Posted on by

Uniden Scanners

One common question people have in today’s Internet and app heavy environments is whether a handheld Uniden scanner or Whistler scanner is really necessary since people can access online police scanners. Handheld police scanners are still an essential piece of hardware for people to own for several reasons.

Running a scanner app on your smart phone limits your channel selections. With an app, you are limited to a few frequencies rather a full spectrum of scanner radio frequencies. With a battery operated handheld scanner you have access to more channels, the ability to monitor your local area better with access to not only sheriff, police, and fir dispatch channels, but also tactical, detective, SWAT, state police, highway patrol, fire ground, and numerous other channels rarely offered on scanner apps. In addition, you can monitor public works, university police, transits and so much more. Remember too, that thousands of local, county, and state agency dispatch channels are not offered on apps since there is no one local in many areas feeding the audio to the Internet. These apps generally rely on hobbyists, who may just decide to take down their feed at any time.

Also, consider you are home during a severe thunderstorm and the power goes out. Your home Internet and cellular hotspot services are down and not working. As a result, you cannot access online police scanners from your computer or smart phone. You have no way of knowing what is going on because you are cut off from the police radio scanner transmissions.

However, if you have a battery operated handheld scanner radio, like the Uniden BCD436HP or Uniden HomePatrol HP2, it does not matter if the power is out or whether your Internet or hotspot service is functioning. You are able to listen and monitor radio frequencies from your local law enforcement agencies, fire departments, and emergency responders, as well as other numerous other agencies in your community, and know exactly what is going on in regards to the severe storm.

If you are like 90 percent-plus of the people out there who buy police scanners to listen to live police scanner audio feeds and fire department audio feeds, you want to make sure you hear all of the transmissions from city, county, volunteer, and state agencies. The easiest way to ensure you are able to monitor all of these transmissions is with a Uniden scanner, like the BCD436HP or HomePatrol HP2.

How to Program a BCD436HP and HomePatrol HP2 Uniden Scanner Radios

The BCD436HP and HomePatrol HP 2 Uniden scanner radios are one of the easiest scanners on the market to program. You do not need an advanced degree in computers and electronics to program this scanner. It is as simple as entering in your zip code into the scanner. The scanner does all the work and downloads all of the available scanner radio frequencies available in your area. If you ever want to update the radio frequencies, like if you take the handheld scanner with you on vacation, you just enter in the zip code for wherever you are and the scanner updates to that location.
