Declan Barry Posted December 29, 2008 Share Posted December 29, 2008 Hi Folks..Is 2.4Ghz equipment univeral around the world? i.e Is 2.4Ghz equipment purchased in America or elsewhere usable here in the UK?RegardsDeclan Quote Link to comment Share on other sites More sharing options...
Brian Lambert Posted December 29, 2008 Share Posted December 29, 2008 Not unless it is CE marked, well not leagaly, it would obviously work! Quote Link to comment Share on other sites More sharing options...
iawnski Posted December 29, 2008 Share Posted December 29, 2008 what about the rx are they the same as here in uk, can you use them and will they work hereif you buy from the states???????? Quote Link to comment Share on other sites More sharing options...
Brian Lambert Posted December 29, 2008 Share Posted December 29, 2008 Don't know about the others but Spektrum receivers will.Brian Quote Link to comment Share on other sites More sharing options...
Tim Mackey Posted December 29, 2008 Share Posted December 29, 2008 The output power of the US Spektrum TX is double that of the allowable power here in the uk, not sure about other brands..but nonetheless that still means - in a nutshell - the answer to your OP Q is NO.

ken anderson. Posted December 29, 2008 Share Posted December 29, 2008 yo-merry christmas to every one--don't find out the hard way -if the radio works here or not-bottom line line is someone could get seriously hurt!!!!!!!!!!!!!! ken anderson.

Andy Anscombe Posted December 29, 2008 Share Posted December 29, 2008 the answer is yes they work but it is technically illegal as the USA are allowed a stronger signal and thus can fly at a greater rangeAndy Quote Link to comment Share on other sites More sharing options...
Brian Lambert Posted December 29, 2008 Share Posted December 29, 2008 Timbo so that would be 200mW erp but Spectrum say 120mW for the U.S. ones.Anyway have a look here for the lowdown. Quote Link to comment Share on other sites More sharing options...

However there is only a very minor reduction in range and no impact on selectivity. And both versions are classified as full range systems capable of controlling any RC aircraft with plenty of margin.The 3dB difference is very minor when you consider the total path budget of the systems:Path = RX sensitivity + RX coding gain + TX power 98 + 18 + 22 = 138dB for the US 98 + 18 + 19 = 135dB for EU versions.So...there you have it from the horses mouth. Now stop worrying about technical guff, buy the UK CE approved gear, and get flying, and stop worrying. Quote Link to comment Share on other sites More sharing options...
Brian Lambert Posted December 29, 2008 Share Posted December 29, 2008 Yes Timbo but what I was trying to point out was that though there is a large difference in the two maximums in practice there is very little difference in output between "our" and the american Spektrum transmitters.The receivers seem to be the same, I have seen some imported ones and they are identical including the CE marking.Anyway with the Puond/Dollar/Yen exchange rate as it is I would think it would not be worth importing them at the moment.Brian Quote Link to comment Share on other sites More sharing options...
Tim Mackey Posted December 29, 2008 Share Posted December 29, 2008 I agree, VERY little real diffrence in useable / noticeable poer, other than in battery life no doubt! Bet the US sets dont las half as long as oursThe DX6i in particular has fantastic battery life. And yes, as far as the Rx are concerned they are the same AFAIK - the O/P should have really been a little more specific about the quipment he was qeurying.

Paul L Posted December 30, 2008 Share Posted December 30, 2008 The Futaba FASST system AFAIK uses the same output power in the US and the UK (in fact all over the world, except France). Therefore any Futaba 2.4ghz transmitter bought from the US should be legal to use in the UK from the point of view of output power. Even so, if it does not have the CE sticker on it, I believe It would be illegal. Quote Link to comment Share on other sites More sharing options...
Frank Skilbeck Posted December 30, 2008 Share Posted December 30, 2008 The Spektrum DX6i has a user setting in the menu's which you set to EU or US, and yes it has a CE sticker on the back. So theoretically you could set it to the higher power US setting, but mine's set at the EU setting and there hasn't been any range issues.

Ultymate Posted December 30, 2008 Share Posted December 30, 2008 I think you'll find Frank that either setting will give you range way beyond that of human eyesight so in reality you're unlikely to encounter range problems on either EU or USA settings Quote Link to comment Share on other sites More sharing options...
Ernie Posted December 30, 2008 Share Posted December 30, 2008 Hi guys, why does my Futaba 2.4 have a wee switch inside that says 'france' What does it do, and what happens if it is wrongly set?ernie Quote Link to comment Share on other sites More sharing options...
Tim Mackey Posted December 30, 2008 Share Posted December 30, 2008 same as the spekky idea.... France have even lower power allowances, so you should set it to France...or move back to blighty Quote Link to comment Share on other sites More sharing options...
Peter 'Ivanna Crashalot' Savage Posted December 31, 2008 Share Posted December 31, 2008 i swear the power level in US is same as UK, the only reason spektrum's EU selection is 10mw is because of france, so it is legal to use the US mode in the uk i think, can anyone link me to a site which has them written on, ofcom or something Quote Link to comment Share on other sites More sharing options...

Peter 'Ivanna Crashalot' Savage Posted December 31, 2008 Share Posted December 31, 2008 i think that is just because of france being part of the EU which for some reason dont want strong 2.4ghz radio waves, i thought the UK and US power outputs where the same, atleast thats what they said at my club's AGM Quote Link to comment Share on other sites More sharing options...
Frank Skilbeck Posted December 31, 2008 Share Posted December 31, 2008 From what I understand US has a higher power limit than Europe, France being the exception which has an even lower limit. But I understand the FHSS systems (e.g. Futaba) meet the regs in both US and Europe (except France) and DSM systems (Spectrum/JR) have different power levels in US and Europe, not even sure if you can buy a DSM system in France.Hence the switch in the Futaba set for use in France.

Tim Mackey Posted December 31, 2008 Share Posted December 31, 2008 I am pretty sure, as has been said in several threads, and on several forums, that peak output power in the US is 200mW and the UK is 100mW - early Spektrum Tx units such as the DX7 were shipped as either US or EU compliant, and using a US version in the UK was / is against the UK regulations.... which limit the power to 100mW. Later sets such as the DX6i have a user settable software switch fitted, to select the correct power output. Any US compliant sets of older variety can be sent to HH UK for "adjustment" to enable them to be used legally in the UK. Quote Link to comment Share on other sites More sharing options...
Bert Posted December 31, 2008 Share Posted December 31, 2008 Just by way of a bit of trivia, if you look at the CE marking on the Spektrum receivers (the ones I have anyway) there is an exclamation mark by the CE mark.This is to show that the marked item does not comply with all of the requirements of every country in the European Union.All anorak stuff I know Bert Quote Link to comment Share on other sites More sharing options...
