AM/FM sets dont get used much out here any more as they can be hit and miss. On my old sets it was common to be able to pick someone up in Queensland but not a block away. Most people use UHF radios for short range communication and HF radios for long range. UHF radios are cheap and a decent package can be picked up for around $400 (less 2nd hand). HF radios are expensive ranging up to $5000. A good second hand unit will still set you back at least $1500. Me I was lucky I got my HF and autotune antenna for nothing.

Hi dullbird,

CB radios are controlled by regulation and the transmission frequencies are restricted to certain bands. Also transmitting power is restricted to 5 watts.

Without knowing the specifications of your radio it is difficult to
know.

Trust this helps a little.

This is what I have found so far, I think it will only be useable in Europe and anyway am/fm sets are seldom used in Australia naymore.

How are the Midlan/Alan CB's different to normal CB's?

These sets are designed primarily for long-distance truck drivers.
Introduced in Oct. 2002, the two Midland/Alan Multi sets can switch to suit the frequency allocations in different European countries, so when you are in these countries, you have access to that country's FULL CB allocation, not just the common European band on FM.

Some countries have AM CB, others have channels slightly different from the "standard" EU allocation.

By switching the unit on while holding down 2 buttons you can select a country from the list and get access to that countries CB allocation on AM or FM, including the Russian 400 channel (25.615-30.105Mhz AM/FM) band.

These units can work as a normal 80 channel UK spec CB just as easily, with UK/EU band change and FM only simply by selecting UK as the country.

IMPORTANT : These sets have been designed for travellers who regularly visit different countries and who wish to make use of that countries legal CB service.
AM and some of the frequencies these sets can operate on are illegal to use in the UK - using these modes here could render you liable to prosecution.

<span style="color:blue">cb radio is dead in this state......


so if you and your travelling companions have cb radios.....you will pretty
much have all the channels to yourselves.....


to communicate with others you will need uhf......which is what everyone uses
these days.....
most people use the small hand held battery operated units which are really cheap....


i actually have both cb and uhf in lurch......</span>

just to clarify a few errors in the previous posts....

CB radio stands for citizens band and both AM (27MHz) and UHF (477MHz) are "CB" radios...

AM/FM relates to the form of modulation used... UHF is in fact a FM radio

AM CB radio in Australia operates between 26.965 MHz and 27.405 MHz..
It appears your Midland radio operates on the same frequencies.. so YES you can use it legally here provided you dont use the extra channels..
HOWEVER as most have mentioned you will not find much activity on this band except for the occasional truckies... I would install it as you already own it.. but would also be purchasing a UHF CB radio.. GME ( www.gme.net.au ) tends to be the favourite and has a better quality audio than most IMO... except for the big $$ Kenwood and Tait radios..

Landyman,
Was just an ommission as of no consequence, the FM frequency of this radio is of no use in Autralia of course, and yes UHFs are actually FM, but they will still require a new unit, that why I did not tie this in. The other channels amy be interesting for listening only, but licences are required to transmit - maybe?.
Even a HF does not require a licence any more.
Geez I remember not too long ago when all cb sets used to have to be licenced.
I think it is just generically people refer to am/usb sets as cbs and UHFs as UHFs. May be incorrect technically.
Would be a good unit if these frequencies were used by many in Australia.
Will have to pull my finger out and get my HF fitted.

<span style="color:blue">if a group of you always travel together....its a good idea to install
the old 27mHz cb radios.....40 empty channels and no ratbags....

and they can be picked up cheap due to lack of popularity these days....

i bought a 40channel SSB unit for $10......and have fitted both to lurch....
now i just gotta get my travel buddies to fit one in their cars....</span>

<span style="color:blue">there are plenty of old 27meg units still lying around forgotten in peoples sheds....

i still got my first one that i ever bought....still works as good as new....
and if it werent for that radio....i never would have met my wife.... 8O

dunno if that is a good or bad thing.....</span>

Currently I only have an old 18 channel AM/SSB. I should be picking up a UHf some time this month. I had to return my loaner.

<span style="color:blue">just go and buy one of those $20 jobs.....thats all you need in convoy....
which is pretty much the only time you use the things.....


you cant have a decent conversation on any of the repeater stations as there is nothing
but ratbags trying to prevent it......
so high powered sets are not required to try and get over the ratbags...
if in convoy you are too close together to worry.....

then you can save up and buy a proper unit to install permanently and forget....
and use the handheld unit as a spare incase someone travelling with you doesnt have one.......</span>

Where do you get the cheap hand helds?
I have been looking for ages but keep finding only $100 and up priced ones.
