The ACMA is Seeking Submissions on CB Channels
The ACMA is presently seeking information on some aspects of the Class licence that covers the use of Citizens Band (CB) radio in Australia.
Use of CB radio equipment is covered under a Class Licence and no individual licensing is required, subject to operation under the conditions of the overall licence. The plan from the ACMA is that the existing systems are operating effectively, and so there is no need to make changes to the licence per se, but they are seeking comments on a couple of specific areas of usage.
1. CB Radio Emergency Channels
- UHF channels 5 and 35 are listed as being for emergency communications only. The ACMA are seeking information on whether access to the public carrier networks (and specifically the 000 system) does away with the need for emergency channels on UHF CB. It is important for anyone with experience in the UHF CB sector, and our public safety agencies to respond if they see a continuing need for these emergency channels to be specifically available for public use in emergencies.
- HF channel 9 – The HF CB service operates on channels in the 27MHz band, and although not as popular as in the early days of CB radio usage, there may still be users on some of those channels. Again, the question is whether there should continue to be one channel dedicated as an emergency channel? The second question here is whether anyone actually monitors that channel regularly, and if the answer is no, then should it be labelled as an emergency channel? If any calls issued on that channel are highly unlikely to be responded to, does it lead to an expectation of support that may not exist?
2. Telemetry Channels
When the existing channel plan for UHF CB was introduced to change channel bandwidth from 25kHz to 12.5kHz, the telecommand/telemetry channels on the old format (channels 22 & 23) were left as 25kHz bandwidth. The ACMA are now seeking responses on whether these channels should be brought into line with the rest of the UHF CB plan at 12.5kHz and make new channels available in the spaces made available. Existing users and equipment suppliers for this type of equipment are encouraged to respond to the ACMA with relevant information.
