Results so far
On 17 May 2021 we started a short survey into the misuse of the UHF CB emergency channels 5 & 35. As of 13 April 2022 we had 113 responses. The results are shown below.
Of the responses over 90% reported they had heard misuse of either one or both of the emergency channels while less than 10% reported they had not heard misuse on ch5. The results below are for those reporting misuse. Reports of no misuse heard are rolled into the overall result shown above, but not in the channel or frequency data below.
|Both 5 and 35||70.59%|
Of those that heard misuse we asked if they had heard operators in five different categories – Business/Commercial, Construction, Road Works, Government and Private/Hobbyist (multiple reports from each response was permitted so the figures below show the percentage reported from the total responses).
|Business or Commercial||53.92%|
|Private or Hobbyist||66.76%|
As can be seen from the above table, the largest proportion of misuse came from private hobbyists, followed by the construction industry, then business/commercial and road works. Government users were the lowest number of recorded users.
The survey also asked how often this misuse was observed (all non-misuse reports said “Daily” so the results below relate only to reports of misuse):
|Most of the week||13.73%|
|A few times a week||15.68%|
To round out the data we also asked whether the operator used their UHF in a car/truck, house or both (these results do include every response, whether positive or negative):
|UHF used in||Instances|
|Car and/or truck||49.56%|
|Both car/truck and home||44.25%|
Some responses also gave us locations of the misuse. The most common of these, in descending order, was:
- Sydney (CBD, West and North)
- Melbourne (and surrounding suburbs)
- Brisbane & Sunshine Coast
- Newcastle (and surrounding suburbs)
A number of regional locations in NSW, Victoria and Queensland were also identified, while a significant number of responses did not provide a location. A couple did provide the name and location of possible offenders so in this cases RREC has made contact with these users in an effort to educate before we need to refer to ACMA.
Farming and farmers were also mentioned in responses as a group that often misuses 5/35 on their farms, especially during harvesting season when activities increase. This included farms in New South Wales, Victoria, Queensland and South Australia.
We’d like to thank everyone that participated in this survey. We will keep it open for a while longer (see form below) and update this page each month as needed. By the end of the year we aim to have a submission to both the ACMA and the Minister for Communications outlining this issue and the need for ACMA action to help resolve the problems.
If you have details of a specific incident of misuse you can send us the details using our Misuse Report. We can then try to contact the users and educate them on these channels.
