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.

UHF CB Channel 11 Usage

UHF CB channel 11 (476.675MHz) is the "unofficial" calling channel, from my listening it does not seem to get much use for that. Generally most UHF CB users either call on the local repeater (channel 2 in the Launceston area) or their own working channel.

Of late I have noticed an increase in the amount of radio traffic on UHF CB channel 11, other than the local channel 2 repeater or channel 40 (the road channel) it has been the most active UHF CB channel in the Launceston area.

I was out for a walk with my daughter in her pram recently and came across some road works, we had to stop to let a truck pass. I got talking to one of the guys who was doing traffic control and noticed he had a UHF CB. He told me that a lot of the road works / construction companies had agreed on using UHF CB channel 11 for this type of work, by having them all on the same channel they can talk to each other and coordinate what is going on. This might also be part of the reason why a couple of companies have migrated from VHF highband to UHF, they can use the one radio for both UHF CB and also their own business frequency.

Portable Scanning - Launceston CBD - 18/4/2017

Today I went for a walk around the CBD with my daughter in her pram. We started off at city park, walked across the CBD to Royal park, back via the Launceston Fire Station and the CBD to KMART and then back to the car. I had my UBC126AT running in close call temporary store mode in the top of the pram, my loggings are below:

81.53750 - TFS (TX)
81.56250 - AMBO (TX)
411.18750 - FIRE-UHF SIMP
462.25000 - KMART LTON
463.40000 - TARGET LTON
476.50000 - UHF CB CH 4
476.82500 - UHF CB CH 17 (Security?)
476.90000 - UHF CB CH 20 (TOLL)
479.57500 - LCC PARK (TX)

UHF CB channel 17 (476.825MHz) also had a hit in the mall, audio was asking for a staff member to do a bag check as a lady was leaving the shop, I suspect this might have been Best and Less.

The Russian WoodPecker

I found this a very interesting read.

TARGET Frequencies - Active



A few weeks ago I noticed the two new frequencies below on the ACMA database for both the TARGET stores in Launceston. I programmed them in to my UBC126AT but as my day to day drive does not take me past them I had not been able to confirm them in use.

463.40000MHz - TARGET LTON
465.31250MHz - TARGET MOWBRAY

Last week I happened to call past TARGET Mowbray and noticed that all the staff I saw had ear prices. On Saturday I had a couple  of spare hours so I decided to head to each of the stores and see if they were active yet.

I started at TARGET Mowbray, I sat in the car for about 20 minutes close to the doors and didn't hear that frequency active at all, I decided to put my scanner on my belt and head in for a walk around with it in close call temporary store mode. Within a couple of minutes I had a close call hit with the CTCSS tone also logged.

After this success I headed in to the CBD to see if the city store were also on the air. Again I had my UBC126AT on my belt, this time I also had an ear piece in to be able to hear the conversations. I spent a little bit of time walking around the store and was able to confirm the frequency is in use, the CTCSS tone in use and some call signs / a general idea of how they use them.

How to ID signals

You are scanning the bands and come across a weird looking and sounding signals - what do you do next?

There is a great wiki on signal identification that contains what they look like on a waterfall and what they sound like on the air.

A great future reference site for the bookmarks list.

NBN Cable Installers on UHF CB

Today I have logged via Close Call some NBN cable installers using UHF CB channel 21 (476.925MHz) in the Riverside area.

Scanning Repeater Input Frequencies - Why would you do it?

In almost all cases, you should program your scanner with the output frequency of a repeater. Since this is the frequency that the repeater is using to rebroadcast all communications and as repeaters with an antenna mounted high up will have much better line of sight to mobiles and portables and cover a much larger area.

When using Close Call mode, you will mostly get hits on the input frequencies of repeaters. This I have found useful for both finding new frequencies in use and also with confirming the user of frequencies, especially on shared repeaters where multiple users are sharing the same frequency but with different CTCSS tones.

As I focus more on traffic analysis (https://en.wikipedia.org/wiki/Traffic_analysis) the content of the message becomes less important than when, where, why and who is using a given frequency. What I have done in the past few weeks is to take a group of the more active frequencies in the Launceston area and program the input frequencies in as below.

72.82500 - ABILITY (TX)
80.15000 - TECS (TX)
80.78570 - LCC (TX)
80.81250 - LCC (TX)
81.53750 - TFS (TX)
81.56250 - AMBO (TX)
157.90000 - BORAL (TX)
158.01250 - TASRAIL (TX)
158.45000 - REDLINE (TX)
158.83750 - TOXFREE (TX)
454.27500 - METRO (TX)
479.42500 - LCC QVM (TX)
479.57500 - LCC PARK (TX)
480.05000 - MARCOMNET (TX)
483.35000 - MARCOMNET (TX)

This limits the radio traffic to only what is physically close to my location. So far my results have been encouraging, a number of times I have been able to visually match what I see (such as trucks from a company who use a shared repeater) with radio traffic on the input frequencies and the matching CTCSS tones.

Over time I will continue to log these results and share them on here on my blog.

Close Call Hit on 157.900MHz

This morning I was driving in Legana with my UBC126AT in close call auto store mode. I noticed some construction work going on near the shopping centre, a few seconds later I got a close call hit on 157.900MHz which is the input frequency for Boral off Mt Arthur on 162.500MHz.

Toll Transport - UHF CB

Yesterday I had to attend an appointment in Newstead. I left my UBC126AT in close call temporary store mode in the car. When I returned to the car, I had a close call hit on UHF CB channel 20 (476.900MHz). After listening to the traffic for a few moments I confirmed this is being used by Toll Transport at the Newstead depot.
