i am going to be programming some of the public uhf cb frequencies into my Motorola GP328's. Do any Australians out there know if you can program the PUBLIC CTCSS codes into a GP328 on public frequencies so there is more of a chance at private communications between me and some of my friends???? I am looking to get UHF CB Channels 1 & 2 programmed with #3 of the 38 PUBLIC CTCSS Sub-Codes. I need to know the exact TX and RX frequencies of uhf cb channels 1 & 2 with CTCSS Sub Code #3 programmed into them. below is the TX/RX frequencies of the 2 channels along with the frequency of CTCSS PUBLIC Sub Code #3 that needs to be merged into each channel. can anyone merge these together and tell me the final TX/RX frequency with CTCSS PUBLIC Sub-Code #3 attached??? thanks....

Channel 1 TX/RX (MHz) = 476.425
Channel 2 TX/RX (MHz) = 476.450
CTCSS Code #3 (Hz) = 74.4

just remember that it don't matter if you have a tpl or dpl code on your radios, anyone listening on csq will still hear you, you just won't hear them. i don't know if you didn't want them not to hear you or if you wanted to filter them out. by adding a tpl or dpl you are not changing or offsetting the frequency, that gets put in a separate box.

What are you asking for, exactly? You just provided all of the information you asked for.

as already stated , no matter what subtone you have , other CBers will here you.
the GP328 will take only 16 channels.

Why? CTCSS is Illegal on UHF CB - full stop.

No it isn't.

Radiocommunications (Citizen Band Radio Stations) Class Licence 2002 wrote: Operating a CB station to transmit audio tones
A person, when operating a CB station to transmit audio tones for initiating communications with another CB station, must:
(a) on a carrier frequency mentioned in item 1, 2 or 3 of Schedule 1, only transmit audible tones for less than 3 seconds in any period of 60 seconds; or
(b) on a carrier frequency mentioned in item 4 or 5 of Schedule 1, only transmit:
(i) audible tones for less than 3 seconds in any period of 60 seconds; or
(ii) subaudible tones.
Note Subaudible tones are used in continuous tone coded squelch systems (CTCSS).

No it is not illegal
lots of people use it on Aussie CB channels
yes you can use it
But every one will still hear you cause they are on CSQ [ carrier squelch]

Ahh OK - I am thinking pre-2002. It was illegal.

Ditto to what everyone else has said - it wont stop people from hearing you. All it does it prevent you from hearing them.

it is illegal for a commerical companys to use CB frequencies but every one does it.
it is not police cause they cant be bothered watching every one.
but if you want to use it you can with subtones

It's not illegal for businesses to use CB. Plenty would like that to be the case though.

yes it is
But as i already stated
it is not policed
no one cares

Nothing in the class license says anything to that effect.

If I'm missing it, could you point it out?

(From the submissions I read about 2002 regarding legalising PL, it was mainly commercial interests who caused this to come about.)

it is not policed
no one cares

It's not policed because it's not illegal, but I'll leave it there.

I find it kind of funny ProFF comes in here, stirring things up after creating an account...... and "LosAngelesCop" is in Australia, no where near LA!

Odd.

I have been into radio since 1977, you do the maths.
If I am telling you it is illegal and no one cares so it is not policed here in Australia.
This is the truth.
Besides you live in LA.
What the hell do you know about what goes on here in Australia.
I don't know the Laws in the USA and i wouldn't say i do cause I don't
here in Australia I can tell you anything about radio that has happen in the last 30 or so years
DON'T TRY TO TELL ME THE LAWS IN AUSTRALIA UNLESS YOU LIVE HERE

And with that....
