On 17 May 2021 we started a short survey into the misuse of the UHF CB emergency channels 5 & 35. As of 19 September 2021 we had 80 responses. The results are shown below.
Of the 80 responses 87.5% reported they had heard misuse of either one or both of the emergency channels while 12.5% reported they had not heard misuse on ch5.
|Both 5 and 35||65%|
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).
|Business or Commercial||23.17%|
|Private or Hobbyist||25.61%|
As can be seen from the above table, the largest proportion of misuse came from the construction industry, followed closely by private users or hobbyists, then business/commercial and road works. Government users were the lowest number of recorded users.
The survey also asked how often this misuse (or non-misuse) was observed:
|Most of the week||12.5%|
|A few times a week||13.75%|
To round out the data we also asked whether the operator used their UHF in a car/truck, house or both:
|UHF used in||Instances|
|Car and/or truck||51.25%|
|Both car/truck and home||42.5%|
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.
