Helmet mic interference from the bike

[Stephane]

I recently purchased this TTSE and my wife jumped on the back for the first time. She loved it which is fabulous :-)
However, when using the comm to talk she could not understand anything I said.
The comm system is a Fodsports M1-S+.
It appears to be interference from the bike! As soon as I switch it off or take a step away or sit on the back seat (bike idling), she can hear me clearly.
Any advice?

I don't know that intercom. Mine have a function that reduces interference and attenuates air noise. It is not entirely effective, but it helps a lot.

On the other hand, it could be that he has some fault in the masses of the microphone of his helmet or in the speaker of his lady.

It would be good if you check the connections of the mentioned connectors. It is possible that, as the cables are so thin, they have become somewhat cut and touch some ground with the cable that carries the signal to the microphone or speaker. Or maybe it is only necessary to insert the connectors properly on the intercoms.

I'd guess what you mean is that she can hear that there is audio but the clarity is the issue?

Might be worth trying something simple like wrapping as much of the the mic cable as you can in kitchen foil to shield against HF emissions being picked up. In theory BT (I'm assuming it is as I'm not familiar with that make) should be less prone to interference on the transmitted / received signal. It's not a solution but it might help you get a better idea of where the problem lies.

Can you try it with another bike?

I'm not familiar withthat system either, but there may be nothing wrong with it !

A fairly commom cause of such interference can be the use of After Market LED Bulbs !

Check if your Trophy has any of these - if it does, disconnect them and check again. 

If not, look for any other electrical equipment that has been added,
and try disconnecting that to see if the cause of the interference can be identified.

Finally you could check some of the Trophy circuits, such as the Audio system,
Stock Lighting, Accessory Sockets / Heated Seats and Handle bars etc
and pull the fuses for each in turn to check.

Hope this helps

Yes, interference from led lights is also possible. The led lights (Chinese). They are very bloody with interference ...

@sin_tiger - Yes, I mean is that she can hear that there is audio but the quality is so bad that she cannot make out what I'm saying. However, I hear her just fine.
The aluminum foil idea is probably the easiest to try.

@coconut - LED headlights; I would have never thought of that. I do have aftermarket LEDs. I won't be able to test it until this weekend.

Thanks all for your suggestions. I'll let you know what I find.

Just to let you know that the "@" symbol is not used on this Forum to alert specific Members,
it has no efffect at all - I believe it is used on some other Social Media type sites.

UPDATE
I emailed the company and they agreed that intercom unit was defective. They are sending a replacement.
