Up Close Radio Scanning

Over the past few years, a number of the more active two way radio users in the Launceston area have gone off the air, in most cases they have either moved to MDT type devices, mobile phones or no longer use radio communications at all. These include some taxi companies, RACT roadside vans and some delivery companies. While these might not have been everybody’s preferred monitoring targets, they were active a lot of the time and had wide coverage areas from their hill top high power repeaters, making hearing them very easy. 

In the past couple of years a number of businesses have started using ear piece communication devices in the UHF band, these are very interesting to listen to but due to the low power they use you need to be very close to be able to hear them, this calls for some up close radio scanning. Below are some examples of the methods I have used to be able to monitor these signals in a “low profile” way. In all these cases I have based this around using my UBCD436PT which is a larger size handheld, if you have a smaller handheld radio then this is even easier. Back when mobiles phones were much larger (bricks) it was easier to pass off a radio scanner as something else, these days that just would not work. 

My daily carry radio kit (UBCD436PT, aerials, cables and so on) is based on a $1 Kmart lunch box, which I have published the details of it here on my blog.  I choose this so as not to draw any unwanted attention to myself or the contents of the lunchbox. It does not scream “expensive stuff inside” and blends in. I take the view that it is better to be discrete with my scanner listening hobby, especially within the view of the public. It does nobody no harm but it is best to draw attention to our innocent activities, which can be easily misunderstood. For this reason I prefer a set and forget type of setup, this means I can’t listen at the time but with using the UBCD436PT’s recorder feature I can later review what it finds. This also helps with blending in. 

Please note: None of this is written to encourage you to attempt to take a banned item in to anywhere, simply as a way to enjoy the radio scanning hobby in a low profile way.

Radio in my vest:

This works best in winter (wearing a heavy vest like this is summer makes you stand out, exactly the opposite of what we want to do). Before you reach your intended monitoring target, turn the volume all the way down and slip your radio in close call mode / with the recorder feature enabled in to a secure pocket, walk around the target area as normal, knowing your radio is logging all the traffic it hears for later review. I have used this method a few times in the CBD area with good results. If possible, enabled the keypad lock so that you don’t accidently press a key and end up with nothing logged.

In my backpack:

As the next step up from having the radio in your vest pocket, in this case before you reach your intended monitoring target, turn the volume all the way down and place your radio in close call mode / with the recorder feature enabled back in to a non-descript / low profile case and then place this in your backpack. This works well in the warmer months when wearing a vest would not be practical or if you are going to be walking around for a longer period of time. If you are careful you can also use the cover of your backpack to check any loggings by keeping the radio hidden in the case. A disadvantage of this method is that some shops do check bags and it can also increase the chances of somebody trying to steal your bag. 

Under the pram:

Really trying to blend in? In this case before you reach your intended monitoring target, turn the volume all the way down and place your radio in close call mode / with the recorder feature enabled back in to a non-descript / low profile case (such as my lunch box case) and then place this under a pram. Trying to do this with an empty pram is not a good idea and I don’t recommend stealing children for this purpose, I am lucky I have my own. Add a nappy bag or a lunch box with food (just don’t get mixed up and give a toddler the one with your expensive radio in) and you can walk around, knowing all radio traffic is being logged and recorded for later review. Very few places check prams and even if they do, they won’t normally check inside a lunch box. 

A mix of all of the above methods has allowed me to confirm a number of UHF headset frequencies and also log various other low power / limited coverage radio systems for later review.

Scanner Funny

One I heard the other day on the local police talk group:
VKT Hobart: VKT to all units. All units please be aware that we are having rolling database restarts between now and 20:00 hours tonight. During this time your in car tablets might not work very well or be much use to you"
Random unit: Are they ever?
Second random unit: They couldn't be any less useful.

UBCD436PT - More Thoughts and Experiences

I have now had my UBCD436PT for a few weeks. Some more thoughts and my experiences:
-  I am still a big fan of its performance on the 800MHz trunking band.
- The VHF / UHF performance is not great. I have now been able to test it in a wider range of locations and it is still not as good at picking up signals, especially in the 70-80MHz band.
- The VHF airband is an exception to the above, it preforms very well in this band.
- I have made great use of discovery mode, it now runs in this mode whenever I am not activity using it for listening.
- Battery life is good.
- Build quality is excellent.
- The Uniden software works well and I am understanding this well.
- The display and back lighting options work well, I often having it running beside my bed and can easily read it.
- The LED alert light is great and after some careful programming I am finding this very useful.
- The system / dept / chan keys are very useful, once you understand how to best use them.

Using the Recorder Feature to Confirm Frequency Usage

In my local area we have a few frequencies which are owned and operated by a two way rental company that then shared these frequencies between multiple users, using different CTCSS tones. This makes confirming who is using the frequency harder then simply being able to look up the user on the ACMA database.

Since purchasing the UBCD436PT, I have found that the recorder feature is excellent for this sort of thing, it not only records the audio but also the frequency, CTCSS tones and other information. Below is a short video of this in use, I have created a new system (called Logging System) on the UBCD436PT and then added the frequencies in question in to this. I can then leave the UBCD436PT recording and then come back later to review these loggings.


Based on my recordings over the past few weeks I have confirmed the following:

485.25MHz / 141.3Hz = Bus Company
485.25MHz / 167.9Hz = Gravel /landscaping supplies
485.25MHz / 173.8Hz = Security

488.55MHz / 123Hz = Cement Company (Hanson?)
488.55MHz / 151.4Hz = Courier 

Over time I will continue to record these frequencies and add extra information as I come across it.

Low Profile Lunch Box Radio Scanner Carry Case - May 2017

Over the years, while involved in the radio scanning / amateur radio / ultralight DXing hobbies, I have used a number of different bags and cases for carrying my radios and associated bits and pieces. Some of these bags and cases have worked very well, others have not for various reasons. 

I have again returned to my love of portable operation, this has meant finding a suitable carry case or bag for my radios to undertaken these activities in parks and other locations while keeping a low profile.

Based on my experience in the past, I decided to move away from a soft bag like I have used recently and started looking around for a hard case. This needed to be big enough to hold my UBCD436PT scanner, aerials, chargers, cords, ear phones and spare batteries but I didn't want to go to a "Pelican" type case due to cost and sizing options, plus they scream "expensive stuff inside", much like camera bags do. I needed to go for something that looked cheap and not valuable but which still provided a good level of protection.

Recently I was at our local Kmart store, they had put a heap of "back to school" items on clearance, including an $8 lunch box, down to $1, for that price I grabbed one as I liked the size of this and the only thing lacking was a way to keep my radio protected. I had an idea of a way to do this. On my home I called past Bunnings and grabbed some foam wrap, red cloth tape and a small piece of metal I could use as a divider.

A few nights later I spent some time in the shed setting this up. The first step was to cut the foam sheeting to go around the metal divider I then used some double sided tape to mount the foam to the case and then wrapped it in the red cloth tape. I then bent the ends of the divider and bolted this to each end of the case.  I then spent some time sorting my various radio scanning accessories and setting up space in the case for them all.

Overall for less than $5 and an hour of my time, I have a case which provides a good level of protection to my UBCD436PT radio scanner, it looks about as "low profile" as you could get and it was cheap. Nobody would pick it from the outside as anything other than a lunch box, just how I like it.

UBCD436PT - Scanner Stand

They say "necessity is the mother of invention". I have been moving my UBCD436PT around the house a fair bit of late as I have been doing various things, I had a mobile phone type holder which I have used in the past with my UBC126AT but found this was not heavy enough to hold the larger UBCD436PT and stop it from falling over. I was recently at Bunnings and found some metal plates which I thought I could use to make a stand.

I bent the top plate until I got the angle correct for my radio (this would vary for different radios due to size and weight), cut out a section for the belt clip to sit in and wrapped it in tape and then attached the top and bottom parts with some small bolts. Total build time was about 15 minutes.

Over the past few days I have been using this, it allows me to use my scanner at the correct angle. While this was designed for a radio scanner the same idea could be used for almost any handheld radio with a belt clip.

UBCD436PT - Using the Recorder Feature with Close Call

Below is a short video of me using the recorder feature with Close Call on the UBCD436PT for unattended logging. This was done about a week ago on rubbish day when I knew that the truck drivers would be active using their radios. Please note that as this is recording hits on the input frequency of 158.8375MHz which is the repeater output frequency of 163.4375MHz.

UBCD436PT - First Thoughts

Recently I was lucky enough to purchase a Uniden UBCD436PT. Below is a link to the Uniden webpage about it:

It has been many years since I have owned a trunk tracking scanner so it has been a big learning curve to get back in to using a high end scanner like this.

I am planning on documenting my progress with this, what I like / don't like and any issues I come across as a reference source for anybody who has one of these or is thinking of getting one.

My focus to this point has been on getting it programmed how I want, working out some of the advanced features and getting my head around the "Sentinel" programming software.

After two weeks of use, these are my first thoughts:
- It works very well for trunk tracking, it can "hear" very well in the 800MHz band and will decode EDACS control channels at very low signal levels. I mostly listen to the West Launceston and Mt Barrow sites which both cover where I live well.
- The VHF / UHF performance is not great, my UBC126AT out preforms it for general VHF / UHF scanning. I have tested this on it's own standard aerial (which is junk and useless), an after market VHF/ UHF whip and also a couple of different external aerials. In all cases it falls short of what my UBC126AT can receive.
- It has so many features and different modes of operation. I have become a big of discovery mode (as can be seen below) which I often leaving it running in for periods of times while I am at work or busy, coming back later to review the results.

Multiple Use Radio Case

With a new scanner having recently joined my radio setup, which I had been hoping to do for a while I have taken some elements and ideas for some of my previous radio cases and used these to cover my two basic needs:
- My daily carry needs. (Orange case)
- My "event" / portable scanning session setup. (Black case)

I had to cut off the top and bottom tabs on the orange case to make it fit (I had not thought to do this before). The end result is that the smaller orange case which has my daily carry kit now fits in the larger black case which has two other scanners, battery charger and other bits and pieces.

AFL at Utas Stadium - 29/4/2017

Today the AFL is on at Utas Stadium. I went for a walk by this morning and was able to log the following frequencies in use:

484.925MHz - Security / Gate Checks
506.75MHz - Audio feed of various ads. 
509.55MHz - Open Mike - Testing from various locations
509.925MHz - O/B talk back. Testing cameras, lighting and general chat.

I am a big fan of Portabase. I first started using it back in 2010. At the time I had been using an Excel spreadsheet for my radio related frequencies and information but I had found some limits of using this. I made a good start but after some issues I gave up and went back to using Excel. I have recently tried Portabase again and have had much better success this time.

PortaBase (portable database) is a program for conveniently managing one-table database files. It is available for many platforms, including Linux, Mac OS X (Tiger and up), Windows (XP and up), Maemo (Diablo and Fremantle), and the Pandora handheld PC. Notable features include:
  • String, Integer, Decimal, Boolean, Note (multi-line text), Date, Time, Calculation, Sequence, Image, and Enum column types
  • Add, edit, and delete rows of data
  • Custom data views (subsets of the columns in any order)
  • Filter the displayed rows using sets of conditions
  • Sort the rows by any combination of columns, each in ascending or descending order
  • Optional page navigation buttons, with custom number of rows per page
  • Add, delete, rearrange, and rename columns at any time
  • Specify default values for columns
  • View summary statistics for columns (total, average, min, max, etc.)
