Frequencies are the same but they use a different step between stations, it doesn't look like they do a US only version but YMMV

According to the manual (available at sangean.com) you can change the tuning step on the WR-22. 

It doesn't say anything about the power supply whether its 110V only or 110/240V.

Looks like the US version is 120V but you have the option of using a 12V PS.

AM is different spacing there, also FM has a different emphasis but on my reciever that can have it changed on it the only difference seems to be a slight change in treble level, doesn't effect the stereo at all.

Yes it seems like a big price difference between US Amazon and everywhere else

So is it possible to step up from 110V to 240Volts? I can see how you would get a "step down" transformer but I've never come across one that steps up to 240V.

With getting a 12V power supply, aren't there a myriad of plugs available for this? The last time I tried to find the correct 12V plug adaptor I found it was an odd size that no-one stocked anymore. I guess this is the risk of ordering such an item overseas.

Not really sure what you mean. Why would you want to step up to 240V?

 I have a Sangean RCR-9 that is DC powered, bought from Amazon. The plug is standard 2.1mm x 5.5mm. I understand from reading the questions on Amazon that the WR-22 is the same. As the radio is not actually shipped with a DC PS it is unlikely to be non-standard if you're expected to provide your own.

Thanks for your answer, yes that all makes perfect sense to me now.

kiwigander: The radios require a low voltage DC power supply.

If you wanted to use the North American power supply that came with it - and if it were not a universal voltage (i.e. 100-250 V) supply - you'd have to step your household 230 V to 115 V. Then the radio's power supply would convert the 115 V AC to 6 or 9 V DC (or whatever the radio needs). That's only feasible if you've got a 230-115 V step down transformer lying idle. Most unlikely.

The Jaycar power supplies come with a variety of plugs to suit different appliances and radios, and I've had no trouble using them for my Sangean radios. This is not intended as a plug for Jaycar - you can find similar power supplies elsewhere. Just factor in $40 for a power supply in addition to the cost of the radio.

Thanks, thats really helpful.
