[ORRando] Wireless computer interference

[Jeff Arasmith]

Some Google work turned up some corroborating stories:


This comment on Peter White's page could mean the light or the hub is the culprit..

I've had a report from one rider with a Shimano Flight Deck wireless computer getting interference 
from a dynamo hub. When he turns on his Lumotec light, he loses his speed readout. I haven't 
confirmed this, as I don't use any cycling computer myself. But if you have a choice, you may be 
better off using a wired computer.


This string at Bike Forums, strongly suggests it's the light that's the problem.
None of these guys are using dynamo hubs.

These are funny stories at Cycle Chat, including a Cateye light interfering with a Cateye computer
http://www.cyclechat.net/topic/30193-wireless-interference-with-computer/
Someone here suggests it's the LED driver in the light.

To me, both the computer and the light manufacturers are to blame.  The light manufacturers 
should build lights that are designed and shielded to emit less radio frequency (RF) noise, 
and the computer manufactures should make systems that have more immunity.  I suspect that 
they know they are primarily dealing with low speed signals and forget about the RF that 
is generated from and large changes in voltage or current from flashing mode or AC to DC 
conversion.

It is not the Son hub - it is the LED headlight. Endelux and Ixon lights both have stopped wireless systems from working for me.
