Hi Guys,
I have just purchased an IC400 for my cruiser and had the power settings tinkered with. Apparently, these units have three power settings that can be used.
I am mainly wanting to stay on the low (5w) setting but may occasionally need to go higher for transmission in some areas.
I have read the manual about five times now and cannot see any reference to selecting the higher power settings.
Does anyone know how to do this?

Ant, I thought that regulations kept those things to 5 Watts max.

Hi Ant, i was under the impression that 5watts was the maximum for civilian bands (CB) radio. The military use higher of course.

Now I believe that the 25 w can only be used on the commercial channels for which you would need a license, (unless you know somebody) It is not set up on the normal 40 UHF channels for 25w (again unless you know somebody)
I think it is also software controlled to reset these things.

I have a licence to operate 27mgh and such. Would this licence cover the commercial 25w channels?

I doubt it, QR operates most of the comms gear for just about everyone including emergency services and telstra in parts and even as a Govt. corporation in remote areas are still limited to 5W. They have to put more towers in to avoid black spots.

You can 'boost' them but you need to software. And yes you do need a licence.

There is nothing you can do "on the unit" each change is done via programming.

The ACMA is the authority for the RF spectrum in Australia. Defence even goes through them. Anyone can apply for a licence, its all about interfering with other users. and who else is geographically close that you could cause interference with. for example a repeater can only be registered for a fixed location but is allowed to transmitt on higher than 5watts in the 477mhz range.

Yes Icom and many other radios are capable of 25w. However the radios are not type approved for 25w on the UHF CB band and never will be, the UHF CB Band is licensed for 5w.

If you have a commercial licence you are able to have 25w for your private frequency in vehicles and you apply for a 50 watt repeater.

BTW it is easy to program the radio if you have the right leads and software.
