Hi all, my partner & I are interested in possibly buying a radio for our travels. We were wondering if anyone here can tell us whether or not PMR Radio's (aka walkie talkies) can pick-up CB Radio frequencies? For example, can we communicate with Truckies and other travellers using CB Radio's through a PMR Radio while we're on the road?
We are looking at a PMR Radio with the following details:
Doro WT87 PMR Two Way Radio Twin pack
Doro wt87 is a long range Walkie Talkie.

-Up to 5km range
-Over 300 channel combinations
-Voice activation (VOX)
-Auto power save
-Low battery indicator
-Headset outlet
-Belt clip
-Keylock

Personally I wouldn't bother with them. Dick Smith sell really good Uniden handsets (quite often twin packs) that will do the job you've mentioned really
well. And just as cheap.
The Dick Smith units are usually only about 0.5watt output power, which is equivalent to about 5kms (bear in mind, what they don't tell you is that's 5kms direct line of sight - no good through hills etc). They have all the usual 40 channels (truckies, touring, local chat and emergency channel (does anyone actually monitor that channel????)
Realsitically, they're nothing more than a glorified toy. Having said that, we have a couple that we take away with us so the kids can be called when lunch is ready etc.
They're no substitute for a base/vehicle mounted unit which, for less than $200 will get you a respectable unit. Most base units run an output of around 5watts (10 times the power of your handheld jobs). Some naughty people run base units at up to 25watts....but that's illegal so I'll shut up ;)
Hope this helps.

Nothing really other than the fact that the Doro units (being imported) will not replicate correctly on Aussie frequencies. In other words, the preset frequencies will be different. As an earlier poster stated, some of the frequencies may interfere with NSW ambos which is VERY illegal. To have them recallibrated would cost around $200 per unit.
Other examples will be that the frequencies will be "off" channel. Example...here in Aus, our car radios on AM frequency go up in multiples of 11kHz, in the Middle East they go up in multiples of 10kHz making a Aus car stereo unusable in the Middle East if wanting to listen to the AM band. So in terms of the Doro sets, out of 40 channels, (without doing the math) you might end up with 2 usuable channels. Which ones is anyone's guess.
For person to person (between the two handsets) communication will work fine, but forget trying to talk to truckies, emergency
services, tourers, roadhouses etc. Likewise, forget trying to access any repeater stations which is where you gain your best long distance communication from.
Seriously and in all honesty, unless you just want them for person to person communication, you'll find two tin cans and a length of string as a better option and far cheaper. Don't waste you money.
My opinion only, but would hate to see you get caught out.

Fab, it doesn't lessen the overall intent of your post but AM car radio freqs in Australia are stepped by 9 khz, just nit-picking.

Yep...you're right GB. I realised that just after I hit the submit button. I was hoping no one would notice my error.
Glad to see someone was paying attention....LOL.

"here in Aus, our car radios on AM frequency go up in multiples of 11kHz,"
- no, in Australia the AM channel spacing is 9kHz.

Yep...thanks Mike. Gone Bush caught me out on that one too. (See previous follow up 5 of 7).
Simple maths is not so simple early on a Sunday morning after spending a night with the Bundy Bear....hehe.
Cheers.....Fab.

PMR stands for Private Mobile Radio - i.e. they have fixed channels as opposed to the shared channels in Trunked or GRN radios.
A PMR radio could be operating on just about any frequency band and are used by all sorts of
services - Rural Fire Service, Police etc.
A PMR radio could be a walkie talkie, a vehicle mounted radio or a fixed radio.
PMR generally means complying with the specifications for commercial radios, so yes, if you programmed the radio with UHF CB channels, it would be legal to use it.

Hi Mike. Thanks for your
feedback. It has given me more of an understanding to what PMR actually means. I have also just received an e-mail back from the supplier of the product I listed and Ch. 40 is in fact programmed into this radio. Thanks again. Tiffiny.

Mike is of course correct,but PMR walkie talkies such as these (with only 8 channels)
are British spec. and usually programmed for so called PMR 446 Band. See:

Hi Tiffany...just be sure that their channel 40 is the same, or shares the same frequency as at least one of our Australian UHF channels.
As a suggestion, perhaps ask them what frequency is their channel 40 and compare that to a list of Australian UHF channels to see if there is a match up.
Assuming there is a match and you're happy to get by with potentially only 1 channel, then go for it.
One last thing....if they come with a desktop charger,
check that the mains power supply is compatible with the Aussie mains power. I guesss you'd need an adaptor plug also.
Best of luck, and let us all know how you get on......
Fab.
