Thread: UHF CHANNEL BANDWIDTH

Yes it will still be legal and the current sets will still work on the existing 40 channels. The new additional 40 channels are being "slotted" in between the existing frequencies.

Frequently Asked Questions


Will my old UHF CB radio still work when the changes take place?

Yes, You existing UHF CB radio will still work after January 1st 2011

Will my old UHF CB radio interfere with other channels?

It is possible that old UHF CB will interfere with new channels but you would need to be very close to another radio to create a problem

Can I talk to someone on a new UHF CB radio with my old UHF CB radio?

Yes, You will be able to talk to another person using a new UHF CB radio provided they are on one of the current 40 channels, if the other UHF CB radio is on one of the newly allocated channels then you will not be able to talk to them

Will I notice any changes when talking on a new UHF CB radio with my old UHF CB radio?

Yes, You will notice that the sound will be distorted but you will be able to talk to each other

It is my understanding that the use of the 'current' 40 channel units will not be supported beyond 5 years and after that their use will be illegal. Also, because of the narrower channel spacing the 'signal energy' will be significantly less and the end user will perceive this as lower volume (ie you will have to turn the sound up).

Here is the link to the draft standard: http://www.acma.gov.au/webwr/_assets...ndard_2010.pdf .You will see, pursuant to s7, that after 1 Jan 2016, older equipment will be deemed to be noncompliant. Also, all new equipment sold 6 months after the new standard comes into force must be compliant with the new standard. The standard is still a draft and there may be changes, but I wouldn't bet on it. I have seen nothing to suggest that it will not commence on 1 Jan 2011, as indicated in the draft.

Thanks for the link. Just what I was after.

i'm yet to see a valid argument for changing the existing setup

It doesnt really matter, does it. if you need a radio to use now, then pretty much you are stuck with a 40 channel set up.

At some stage in the future though, this set up will be redundant, and you will need to replace it.

So, do you really need one?....or can you wait?

Perhaps the question to ask your supplier is: can the radio be programmed for the new channels?

For what it is worth... the Icom 400Pro can. I have a 400Pro.
As far as I can see the Icom 440 can't. I don't have one.
Looks like the GME 36xx and 38xx radios can. I have a 3840.

If any one can provide a list of radios that can be programmed it would be good.
Also, when will the "new" radios become available?
