Right Way to Program Your Scanner - Pt.2
Programming Trunking Talkgroups & Banks
In
a trunk radio system (TRS), users share a group of frequencies. Users are
assigned one or more numerical group id’s called “talkgroups.” Field radios are
programmed to only pick-up transmissions for that group.
In a large TRS, you
may find that there are a large number of users including police, fire-EMS,
public works, street maintenance, animal control, city engineers, etc., etc.
Since each user could have one or more talkgroup ID’s, a TRS could have dozen’s
and dozen’s of talkgroups ID depending on the number of users.
Talkgroup
ID Banks
Trunking
scanners allow you to program talkgroups ID’s into “talkgroup banks”, usually
5-10 banks, each with room for 5 talkgroup ID’s as shown below.
This is VERY
useful as it eliminate having to listen to every user and talkgroup on a TRS,
especially if there are dozen’s of talkgroups.
The
key to monitoring a trunk radio system is to strategically program talkgroups
within talkgroup banks that can be used to your advantage. Talkgroups for a
particular use or agency should be stored together in one talkgroup bank.
Police in one, fire in another bank and so on. Talkgroups banks can then be
turned on & off and/or individual talkgroups can be locked out.
Bank 1 –
Trunk Radio System Name
·
Talkgroup ID Bank 1 (Police)
·
Talkgroup ID 1 (Dispatch)
·
Talkgroup ID 2 (Tactical)
·
Talkgroup ID 3 (Detectives)
·
Talkgroup ID 4 (SWAT)
·
Talkgroup ID 5 ()
·
Talkgroup ID Bank 2 (Fire)
·
Talkgroup ID 1 (Dispatch)
·
Talkgroup ID 2 (Response)
·
Talkgroup ID 3 (Fireground)
·
Talkgroup ID 4 (Rescue)
·
Talkgroup ID 5
·
Talkgroup Bank 3
·
Talkgroup Bank 4
·
Talkgroup Bank 5
In
the example above, if you just wanted to monitor police you, you would turn of
Talkgroup bank 2 and any other banks you have programmed and just have the
scanner monitor bank one.
Note:
Some trunking scanners may have “sub-bank” within each main
bank allowing for more talkgroup storage such as shown below:
·
Talkgroup ID Bank 1
·
Talkgroup ID Sub-bank 1
·
Talkgroup ID 1
·
Talkgroup ID 2
·
Talkgroup ID 3
·
Talkgroup ID 4
·
Talkgroup ID 5
·
Talkgroup ID Sub-bank 2
·
Talkgroup ID 1
·
Talkgroup ID 2
·
Talkgroup ID 3
·
Talkgroup ID 4
·
Talkgroup ID 5
·
Talkgroup ID Sub-bank 3
·
Talkgroup ID Sub-bank 4
·
Talkgroup ID Sub-bank 5
·
Talkgroup ID Bank 2
·
Talkgroup ID Bank 3
·
Talkgroup ID Bank 4
·
Talkgroup ID Bank 5
And that is pretty much it on programming talkgroups into your scanner for optimal monitoring. Refer to your scanner's manual for specifics on programming frequencies for your trunking system.

Right Way to Program Your Scanner - Pt 1
Note: In this first of a two part article, I will go over the best way to program conventional frequencies into your scanner and cover the programming of a trunking system in part two.
A Common Programming Mistake
Two
common mistakes I’ve seen scanner listeners do is programming all their
frequencies in one or two banks until they’re full and monitoring every
frequency of every police and/or fire department they have programmed in their
scanner all at once!
This is the wrong way to monitor. Why? Well, if you’re
monitoring everything at once, your scanner will stop on every transmission. By
the time the scanner cycles back to your local area frequencies, you may have
missed a critical call near you - this is especially true if you live in a
populated area with lots of radio traffic continuously going on.
The
correct way is to monitor what is going on in the area you are in at the time.
For example, if I’m at home, I want to know what is going on around me – not
what’s going on a city or two away so I would only monitor my local police and
fire department.
If something major happens on the city’s borderline or a
pursuit is coming into my area from a neighboring agency, I will hear about it
over my local area’s dispatch. If I’m out traveling, then I monitor the area I
am in at the time.
Programming Conventional Channels &
Banks
Since
channels can be locked out and channel banks turned on & off, the key is to
program frequencies into channels banks that can be used to your advantage.
Frequencies for a particular use or agency should be stored together in one
bank.
You could put the local police department in one bank and the fire
department in another bank and so on. For example, let’s say you have a
200-channel scanner, most likely, this scanner would be divided into 10 banks
containing 20-channels each.
You could then program frequencies for a
particular use in each bank such as I have done below:
·
Bank 01 – Covina PD (My Local PD, 5 frequencies)
·
Bank 02 – LA County Fire (My Local FD, 10+ frequencies)
·
Bank 03 – West Covina PD/FD (Neighboring PD to the South, 4
frequencies)
·
Bank 04 – Baldwin Park PD (Neighboring PD to the West, 2
frequencies)
·
Bank 05 – Azusa PD/Glendora PD (Neighboring PD’s to the
North, 4 frequencies)
·
Bank 06 – Los Angeles County Sheriff (Neighboring PD to the
East, 14 frequencies)
·
Bank 07 – Local
Highway Patrol Frequencies (2 stations, 4
frequencies)
·
Bank 08 – LA City Fire (10+ frequencies)
·
Bank 09 – News Media Frequencies (4 news channels, 10+
frequencies)
·
Bank 10 – San Bernardino County ’s Valley Trunk Radio System
Note: Bank 10
is a trunked radio system and would not apply to a conventional scanner.
Turning Channel Banks On or Off
You
can turn banks on and off at the touch of a button. In the example above, if I
only want to monitor my local police and fire department, I would leave banks 1
and 2 on and turn off banks 3 through 10.
Now, let’s say I hear of a police chase
going on in West Covina
(neighboring city) over my local police channel. I could simply turn on bank 3
and manually select West Covina ’s
dispatch to listen in or simply turn banks 1 and 2 off and just monitor bank 3.
Now, let’s say I have to go to San
Dimas on a business heron. I simply turn on bank 6 and
I’m in on what’s going on in San Dimas .
Same goes for traveling on the highway, I turn on bank 7 (Highway Patrol) and
I’m good to go.
Note:
Keep in mind that some large agencies may require more than one bank.
This is the end of part one. In part two, I will go over the best way to program a trunking system in to your scanner.

Police Scanner Range & Reception Issues - Pt.2
This post is part two of a two-part series and covers factors that affect the range and reception of your radio scanner. Range and reception is basically how far you can pick up any given signal and how clear those signals come in.
In part one, I covered range and reception issues such as Line of Sight, Frequency Behavior, Atmospheric Conditions, Skips and Propagation, and Surrounding Terrain.
In this second part of range and reception issues, I will cover the remaining factors that affect your scanner's range and reception including; Type of Antenna Used, Indoor Reception, Electrical Noise, Birdies, Battery Power, Station Transmitter Power, and Repeated or Non-Repeated Stations. Let's get started.
Type of Antenna – the type of antenna you are using plays a big part. If you are using a standard rubber ducky antenna (standard on handhelds), you will not be able to pick up distant signals then if you where using a telescoping or outdoor antenna.
When you purchase a base/mobile scanner, it comes with a telescoping antenna (mobile scanners come with a mobile antenna). These work well, however, to maximize your receiption, an external antenna is highly recommented. Learn more about the different types of antennas that are available on the market on our "Police Scanner Accessories".
Indoor Reception – indoor reception will depend on what type of structure you are in, wood, steel, or concrete. Generally, reception of lower frequencies inside of a steel structure will be weak. Receptions of higher frequencies within a steel structure are not generally affected. Reception within a wood or concrete structure varies, but is generally fair. If you are listening from home, connecting an external antenna will boost your reception and extend the range of reception.
Electrical Noise – electrical devices can generate radio signals that can be picked up by your scanner resulting in interference with existing frequencies. Causes include electrical machinery, vehicle ignitions, motors, power lines, florescent lights, etc. Interference from electrical noise usually occurs with lower frequencies.
Birdies – birdies are signals that are internally generated by a scanner that can cause interference with some frequencies. If you have a problem with a birdie frequency, simply lock it out. See this blog post of a list of commonly known birdie frequencies.
Battery Power – the bottom line here is that fully charged or fresh new batteries will give you better range and reception than if you are running on weak ones. Most scanners on the market now include a "Battery Low" indicator to let you know when your batteries are running low. If your scanner does not have this feature, you can usually tell your batteries are getting low because reception starts to break.
Station Transmitter Power – base station transmitting power is measured in wattage. The more watts a transmitting station puts out, the further the signal can be received. You can learn more at the FCC.gov website.
Repeated or Non-Repeated Stations – if a radio is being used in simplex, or “talk-around” mode, then that means that each radio is communicating directly to the other radios on that frequency in that area. Simplex range can vary from several blocks to several miles depending on how much power the radios are putting out, the type and position of your antenna, and the surrounding terrain. This range is typically 3-5 miles. For ranges beyond this limitation, a repeater system is used.
A repeater is a device that is used to extend the range of mobile and portable radios. Public safety agencies need to communicate using portable or mobile radios over the distance limitations posed by handheld and mobile radios, which is approximately 3-5 miles. A repeater also allows communications where buildings usually block the radio signals.
Generally, a repeater is placed on a building, radio tower, mountain, or other tall structure. The higher up the repeater's antenna, the larger coverage area, or range the signal will have. The repeater works by listening to what the radios are transmitting and simultaneously broadcast it back over a larger area.
Hope this information was helpful.
That's it for now. Till next time stay safe and happy scanning!

Police Scanner Range & Reception Issues - Pt.1
This article is a two-part series and covers factors that affect the range and reception of your radio scanner. Range and reception is basically how far you can pick up any given signal and how clear those signals come in.
These factors include: Line of Sight, Frequency Behavior, Atmospheric Conditions, Skips and Propagation, Surrounding Terrain, Antenna limitations, Indoor Reception, Electrical Noise, Birdies, Battery Power, Power of the Transmitting Station, and if the station is Repeated or Non-Repeated.
In this first part of range and reception issues, I will cover several of the factors above in the order listed, with the remaining factors to be covered in the next post. Let's get started.
Line of Sight - line of sight means you usually cannot hear transmissions beyond the horizon, or approximately 30-35 miles away. This is mainly due to frequency behavior.
Frequency Behavior - lower frequencies behave different than higher frequencies. Lower Frequencies travel farther giving you greater range. On the flip side, higher frequencies travel shorter distances reducing your range. Basically, you can hear signals in the 30MHz bands much farther than frequencies in the 800MHz band.
Atmospheric Conditions – atmospheric conditions can affect range and reception. For example, in the summertime, reception is stronger and range extends farther than in the wintertime.
Skips/Propagation – unusual occurrences where signals from hundreds, even thousands of miles away are received. A skip, also called “sky wave propagation”, occurs when radio waves bounce off the ionosphere and return to earth. Skips are most common in the summer months and usually affect the VHF-Low band under 40 MHz or so.
Surrounding Terrain - the surrounding terrain can affect reception in different ways. If you are on flat land or water, reception will be at its greatest. If you are in a mountain or canyon area, your scanner will have trouble receiving radio signals or may not be able to receive signals at all with the standard (rubber-ducky) antenna.
Antenna Limitations - the type of antenna you are using plays a big part. If you are using a standard rubber ducky antenna (standard on handhelds), you will not be able to pick up distant signals then if you where using a telescoping or outdoor antenna.
When you purchase a base/mobile scanner, it comes with a telescoping antenna (mobile scanners come with a mobile antenna). These work well, however, to maximize your receiption, an external antenna is highly recommented.

Indoor Reception – indoor reception will depend on what type of structure you are in, wood, steel, or concrete. Generally, reception of lower frequencies inside of a steel structure will be weak. Receptions of higher frequencies within a steel structure are not generally affected.
Reception within a wood or concrete structure varies, but is generally fair. If you are listening from home, connecting an external antenna will boost your reception and extend the range of reception.
In the next post, we will cover the remaining factors that affect range and reception including Type of Antenna Used, Indoor Reception, Electrical Noise, Birdies, Battery Power, Station Transmitter Power, and Repeated or Non-Repeated Stations.

Incident Audio - Paramedic Falls from Overpass
Last Thursday (2/9), I featured
an article on our Facebook page about Alexandria Fire Department Paramedic
Joshua Weissman (33), who fell from a bridge overpass while at the scene of a car
fire and was critically injured.
Unfortunately, Weissman
has died from head injuries sustained in the fall.
Although the accident is
still under investigation, it is believed that Weissman was climbing over a cement
barrier to get to the vehicle when he fell through the gap and into Four Mile
Run Creek, approximately 30 feet below the interstate hitting his head on rocks
in the shallow creek.
In addition, a link to the audio recording of the dispatch and rescue operations of fellow firefighters working to save Weissman during this incident is included below. I have also put together an interactive Google map of the incident scene location for reference while listening to the audio recording of the incident.
You can read about the incident at the following link:
