Hi Roger

funny you should mention that, as I have just read that. I was taking BMFA news with me as i am flying to NY on Sunday for work and just happened to flick through quick before packing in luggage, meeting up with 'Dustflyer' and was going to show him our famous BMFA rag!

Ok i have undertaken many issues with CE markings on electronic equipment and if you modify equipment then the emphasis is on that person/company to ensure it complies etc. I kow what you say about testing and expense is true after spending ££££££££ to get Inverter drives CE marked.... Yes i know you have to submit a particular example for testing and final production versions cannot deviate from submitted version.

You could always achieve the same as a Futaba module ie having a built in aerial by simply screwing on a 2db aerial to the SMA connector on the back of the Spektrum module making sure you use a 'CE' marked aerial..

Also the work has to be done by a suitably qualified person in that particular field (which i am) The mod i have done is exactly the same that you would find in a 2.4Ghz JR 12 DSX, JR 9 DSX and Futaba 2.4Ghz... My Tx module PCB is no different in operation than the 'proper versions' and i use the same actual RF lead and SMA connector that comes fitted inside the module. I have had this mod done as soon as the modules hit the market and performance and reliabilty has been 100% flying prop, jet and helicopters.

They plug the aerial straight from the aerial to the PCB via a UFL / IPEX connector. Now electrically that way of 'doing the job' is correct with any high frequency you should always try and eliminate 'joins' and leakage/db loss will certainly be reduced when using a single RF lead and in my opinion they way Spektrum designed their 'quickfix' is appalling leading to possible cracks and breaks in the RF lead. I know that the mod i did is technically far superior than the Spektrum module with their outside RF lead and i challenge anyone to state that this is not the case. Take for example their quick mod when they realised that the Tx could fall over and hit the SMA connector, what did they do? They bolted a peice of flat steel on to the SMA connector to help it avoid being damaged.

Just remember that manufactures do not always get it right, also having seen some of the rubbish 2.4Ghz Tx's (not just RC) that the EU allows to be placed in our market.... i think you get the picture

This is not aimed at anyone in particular but what amuses me the most are the guys on these forums that comment on electronic issues when they have not got a clue what they are talking about...[sm=drowning.gif]

Personally i am more worried about the idiots that overfly the 'pit box' area...even after having it pointed out to them on several occasions [:@] plus Futaba 2.4Ghz Rx's that shut down once they need to throw the bed clothes off coz they are too warm!
