Firmware, Firmware, who needs Firmware?

OK, you have this whiz-bang multi-hundred dollar scanner sitting there and you want to make it much more better! You read about Firmware Updates but haven’t a clue what this means. Should you update the firmware on your scanner? If so how do I do it? What does it all mean? What is the meaning of all this? Can you do this for me?

First, let’s explain WHAT firmware is. Firmware is the operating system of your radio, it works behind the scenes and tells the radio how to deal with things like keyboard inputs, frequencies, etc. Just like your computer or phone has an operating system (Like Windows 10, iOS etc..) scanners do too. Remember, scanners these days are miniature computers, they work much in the same way.

Firmware updates are released for a couple reasons. They either fix a problem or add/change features. Sometimes they do both. As an example, the BCD436HP’s most recent firmware update added the ability to add ProVoice digital, the version before that addressed an issue with clock settings.

When updating firmware one must follow ALL instructions CAREFULLY! You have the possibility of “bricking” your radio if you don’t do it right. This means that your $500 scanner may now be more useful as a brick than a radio… Follow the provided instructions to the letter and make sure that the program and firmware file you use is intended for your radio. The firmware for the PRO106 will not work on the PRO97!

Before trying to update the firmware on your radio make sure you have properly downloaded the firmware file itself as well as the installation program (if needed) BEFORE you start. If you do not have a replacement firmware file to install do not start the process since this erases the existing firmware to make the radio ready for the new version. No new version means no radio once you get going.

Some radios firmware updates are easier than others. The HomePatrol type radios use a program called Sentinel to check for new firmware versions and install them (easy, safe). Other Uniden scanners use a “Bearcat Version Updater” program to install a new update. GRE/RadioShack/Whistler scanners also use an application to install new firmware versions (nerve-wracking maybe).

What they all have in common is that they require a computer running Windows to update. You can use also a Mac as long as you are running Windows on it (with Bootcamp, Parallels, Fusion etc.). You also need the appropriate cable to connect from your computer to the radio. This is usually done via USB but some older radios use a Serial port.

Before updating your firmware make sure you have the following on hand:

  • The radio you want to update
  • The proper cable for your radio, along with the drivers already installed (if needed)
  • The Firmware Updating program appropriate for your radio
  • The actual firmware file itself
  • A strong sedative or plenty of alcohol to calm your nerves (optional)

Follow the instructions included with the firmware update TO THE LETTER. Make sure your radio and the computer can communicate properly. If you have programming software for your radio then read it first and save the programming file just in case you need to restore it to the radio. This also ensures that the radio and computer can communicate.

We also suggest that you check the RadioReference forum for your radio to see what other peoples experiences have been. Reading about someone else’s mistake is a lot easier than trying to fix your own.

Owners of PRO651 and PRO652 scanners that had tried to update their radios’ firmware versions had issues since no firmware updates were available until recently. Now one can download them and install them so previously bricked radios can be reincarnated.

ScannerMaster can update the firmware on many different models of scanners. Download the Hometown Programming Form for your radio and check the Firmware Update option if you would prefer our expert programmers to do this for you. We keep them heavily sedated all of the time already so their nerves are steady. Firmware Updates for “Zip Code Scanners” (HomePatrol, 436/536 and the WS1080/1088/1095/1098 series scanners) is included with the Setup and Optimize package already, it is an extra cost option for other scanners. If you aren’t sure call us and we will let you know.

 

Windows 10 and Scanners

Many people have recently been upgraded to Windows 10, whether they like it or not. For most people it seems to work fine, it just looks different. Most scanner software, such as ARC products, Sentinel and EZ-Scan works just fine in Windows 10 but might take a few steps to get it to work. Here are a few steps to make your transition a little easier:

1)         Update the cable.

If you have a Uniden XT series scanner and use the USB-1 cable make sure you have the newer version. There are 2 versions of the USB-1 cable. The older version will not work in Windows 10 (or Windows 8 for that matter). The ones we sell now work just fine in all versions of Windows. If your cable worked in Windows XP or 7 and no longer works in Windows 10 then it probably needs to be replaced by a newer version. You can also try a USB-Serial adapter and the Serial Port cable that came with your scanner.

Most RadioShack, GRE and Whistler orange, blue and black USB scanner cables seem to work fine in Windows 10. If your scanner (Uniden, GRE or Whistler) has a “Mini-USB port on the front or side of the radio that looks like a little trapezoid then a standard USB device cable will work.

2)         Update the driver.

Some cables and scanners require drivers. These are small files that tell the computer how to relate to and communicate with the radio. Check the ScannerMaster page for the cable or radio that you have for links to the current drivers. Most of the time it is better to install the driver first, then plug in the cable or device. Make sure that you install the driver for your operating system. If Windows 10 isn’t listed then use the Windows 8 driver, chances are it will work fine.

3)         Update the program.

Sometimes the application itself needs to be updated for Windows 10. Just like drivers however, if it worked in Windows 7 or 8 it should work in 10.

4)         If all else fails reinstall the program.

Sometimes after you upgrade to Windows 10 you will still not get the radio and program to communicate. We have found that many times, especially with ARC products, simple uninstalling the program and reinstalling it will fix your connection issues. Make sure you are updating to the latest version of the program. You can download the latest versions at the program’s website. Your activation keys will still work with newer versions of the same program.

As with any program, your results may vary. The above steps will fix a majority of the issues with scanner programs, they have fixed every issue I have had. Depending on the computer hardware, software, operating system and a host of other factors you may have an issue that just doesn’t want to work even after doing all this. If you still get stuck then you may need to contact the software’s support department.

Scanner Tip: Indoor Antennas

Chances are, if you have a scanner in the house, you have wondered if you need an outside antenna. While an outside antenna will almost always work better than an indoor antenna, sometimes that just isn’t feasible. If you live in a rental property, apartment or condo, or in an HOA restricted area you may not be able or allowed to install an outside antenna. Sometimes you just don’t want to go thru the work to do it. Maybe the spouse or significant other just won’t allow it.

There are alternatives, but as they are also compromises, they may work as well. They may however be good enough to allow you to listen to your targets. Depending on your unique situation, some or all of these ideas may or not work for you. Remember: There is never a guarantee that any of these ideas will ensure that you will be able to monitor your targets.

Let’s start with the simple ideas first. Your new scanner comes with a back of the set (or side of the set for a Home Patrol) antenna. This is usually a metal telescoping rod or a rubber-duck style antenna. Sometimes better reception may be had by a simple relocation or tilting the existing antenna. Maybe move the radio with its antenna closer to a window or away from the large metal objects will help.

The next step would be a better BOS (Back Of Set) antenna. ScannerMaster sells a variety of antennas, from direct replacements (if you lost or broke the one that came with the radio) as well as more advanced antennas. If you mostly monitor 700/800 MHz. systems a specialized antenna for these bands will work better than a general use antenna.

If these don’t help, then you may need a remote inside antenna like the Nomad. The Nomad is a wire antenna and is amplified (active). This allows you to mount the antenna in a better location and leave the radio where you want it.

The next step might be using a base station antenna indoors. ScannerMaster has several of these types. Basically this means a base station antenna with some sort of base to support it along with appropriate coax and connectors. These can be set up on a balcony or behind the drapes for aesthetic purposes.

You can also try a mobile antenna adapted to home use. Try a magnet mount antenna on top of a large metal cabinet, window air conditioner or balcony railing. Window mount antennas can be mounted on an apartment window just like you would on a car. Suction cup mounts work in a home just as well as in a car.

If you have access to an attic then you might try putting a base station antenna there. Try to stay away from large metal objects. If you have metallic shingle liners or solar panels they would likely interfere with your reception.

If you install an antenna outside, either on the roof or a tower, make sure to properly ground the installation to protect from lightening and watch out for electrical wires! Consider having them professionally installed. Use a high quality coax. Usually thicker cables work better at higher frequencies and longer distances. 50 or 75-ohm cable is fine for scanners since you will not be transmitting thru them. We will have a blog post soon all about Coax!

When bad things happen to good scanners: Heap Errors

On certain Radio Shack, GRE and Whistler scanners, specifically the ones using Object Oriented programming, one can be beset with an error message that reads “Heap Error” along with some seemingly random text.

These are caused when the radio doesn’t know how to deal with an Object programmed into the memory, usually a Talkgroup (TGRP) not assigned to a  Trunked System (TSYS).

If you can get into the radio programming you should make sure ALL talkgroups entered as Objects are assigned to a Trunked System. This is pretty easy to do in ARC500 or other programs but a lot more difficult without software. These radios are hard enough to program manually let alone find orphaned TGRP objects.

When programming by hand be sure to associate every TGRP with a TSYS BEFORE saving it. When programming with software sort the TGRP list by TSYS and make sure all are assigned to a TSYS. If it says “New” for the TSYS then you need to change or delete the TGRP. Also check for duplicates in your list of TGRP’s. These can also cause errors.

If you don’t have software to program the radio and can’t get into the radio to edit the objects you may well have to reinitialize it and start all over. (Press 0, then 1, then enter during the startup screen.) While this will erase the radio it will get rid of the dreaded Heap Error. If you have software you can usually read the radio even if a Heap Error is present.

Object Oriented programming is used for the following scanners:

GRE: PSR310, PSR410, PSR500, PSR600

RadioShack: PRO-106, PRO-197, PRO-651, PRO-652

Whistler: WS-1040, WS-1065

Scanner Tip: Everything you need to know about trunking but were afraid to ask

In the old days of scanning things were pretty simple, you put in the local police frequency to listen to the police. In many parts of the country however, this no longer works. Most cities, many counties and even entire states use Trunking Systems. What are trunking systems and how do they work?

The best way to explain how a trunking system works is the analogy of a set of bank teller lines. The bank has 5 tellers, you can line up at any of the 5 lines and hope your line goes faster than the others. Then you get stuck behind the lady that wants to have her penny jar counted by hand…

These days however, banks have a single queue and you go to the next available teller when you reach the head of the line. This is exactly how a trunked radio system works: All users are in one queue and get assigned the next available channel. Instead of having a separate frequency for the FD, one for the PD and another for the ambulance, they just go to the next channel that isn’t being used.

All this is controlled by a computer system called, appropriately enough, a “Controller”. The Controller watches the system and when a radio requests to talk it assigns that radio and any other radio in its group to a channel. All this happens in a fraction of a second.

Radios have all the frequencies used by the system programmed into them and the system is broken down into various virtual channels, called “Talkgroups”. Talkgroups are assigned to various uses like channels would have been before. For example, Mayberry PD might be assigned Talkgroup 101 for Dispatch, 102 for Car-Car and 103 for Detectives. Mayberry FD might be assigned Talkgroup 123 for Dispatch, 124 for Fireground and 125 for Tactical. If Mt. Pilot is sharing the system they might be assigned Talkgroup 287 for Police Dispatch and so on.

There are several types of trunking systems but they all work in much the same way. There are differences in the way they get programmed into scanners as well. The main types of trunked systems in use by Public Safety agencies in the USA include Motorola, EDACS, LTR, APCO25 Phase 1 and APCO25 Phase 2.

For scanner listeners these trunked systems add a layer of complexity to the programming. Depending on the type of scanner and the type of trunked system the method used to program differs. For newer Unidens you program in a “System” to identify the type of trunking, then “Sites” to put in the frequencies used and lastly “Groups” for the talkgroup listing. Whistler, GRE and Radio Shack scanners with Object Oriented programming work differently. On LTR and EDACS systems you have to identify the proper “LCN” channel numbers, these are usually well documented at www.radioreference.com. Motorola and APCO25 systems do not need the frequencies in any particular order.

HomePatrol and other scanners with the Database feature will have these Trunked System parameters already programmed so you can just select the Service and location to listen to them. They do all the heavy lifting for you.

Scanner Tip: Care and feeding of scanner batteries

If you use handheld scanners then you have to manage batteries. Most scanners come with or use rechargeable Nickel Metal Hydride cells, often abbreviated to Ni-MH. There are still some older Nickel Cadmium (“Ni-Cad”) cells still around. There is also a newer technology called Lithium Ion (“LI”). If you still use one of the older scanners with composite battery packs (like the BC250D or BC296D) these likely use or NiMH battery packs.

Current scanners almost always use “AA” sized batteries. AA Ni-MH batteries are very common these days and can be found almost anywhere and are also used in a wide variety of different applications. LI batteries are more expensive but are lighter in weight and provide longer life in many instances.

If you charge your batteries in the radio then remember that it is likely set up for Ni-MH. If you use Ni-Cad or LI cells then the charge times will be different. If your radio supports altering charge times then you could change it to match.

Whatever you do make sure that ALL the cells in the radio are the same! Do not mix different types of cells. Also make sure that you do not try to charge alkaline cells like Duracell or Ray-O-Vac’s! This is an easy way to blow things up and make nasty things happen. If you do this warranty will not cover you and the repairs are on you.

If you want to use rechargeable batteries that are different than the ones that came with the radio then consider a separate charger. This would allow you to manage 2 or 3 sets, one for current use and another for standby when the current ones are depleted and a third set in the charger. Make sure the charger you use is appropriate for the batteries you use.

What about Alkalines? Alkaline batteries, such as Duracell’s, Energizer or Ray-O-Vac brands, are great for scanners. You do need to make sure that you do not try to charge them. On many Uniden scanners there is a tiny switch inside the battery compartment that you can select Alkaline or Ni-MH. If you select Alkaline the radio will not attempt to charge batteries in the radio. If you have a RadioShack, GRE or Whistler handheld scanner then the yellow battery holder will charge your batteries when the radio is plugged into an outside power source, so do not use the yellow holder for alkalines. The black battery holder is used for alkaline batteries.

One other thing to consider is that rechargeable batteries produce a slightly lower voltage than alkaline ones do. Typically rechargeable cells produce 1.2 to 1.25 volts compared to 1.5 volts for alkalines at full charge. Usually this is not a problem; the extra quarter-volt per cell is not going to burn up your radio. Using higher voltage alkaline cells will allow the radio to run a bit longer before the battery warning starts.

Here is a little hint for users of later Uniden scanners: You can see how many volts your battery has at any time by pressing the rotary knob down while scanning. Make note of the voltage with fresh cells and the voltage when the battery warning starts. This will give you a good idea of when to expect the need to change or charge the batteries.

I always try to keep an extra set of batteries handy when I am out and about. Save those little battery boxes or use something to keep the batteries from shorting and bouncing around. I use a prescription bottle; larger ones are perfect for 3 or 4 AA’s! I can then toss that in the glove box. Just remember to take off the label so the world doesn’t find out what meds you take. Do they make a pill that will cure a scanner addiction?
