I don't know if this will help your problem but here is my experience.  

My neighbor's garage door would open and close when I was on 10m CW.  Ferrites 
didn't help, but we put a disc ceramic bypass capacitor across the leads from 
inside (manual opening) switch for the door.  This cured the problem.  It seems 
wires for the switch were a pretty good 10m Rx antenna.
